Inner German border

The Allied zones of occupation in Germany, highlighting the inner German border (heavy black line), the originally Soviet-occupied zone (red) and the area from which UK/US troops withdrew in July 1945 (purple). The provincial boundaries in gray are those of Germany until 1933 prior to the Nazi party's rule, and differ from the modern federal states established later.

The inner German border originated from plans by the Allies of World War II to divide a defeated Germany into occupation zones.[7] Their boundaries were drawn along the territorial boundaries of 19th-century German states and provinces that had largely disappeared with the unification of Germany in 1871.[8] Three zones were agreed on, each covering roughly a third of Germany: a British zone in the north-west, an American zone in the south and a Soviet zone in the East. France was later given a zone in the southwest of Germany, neighbouring with France, carved out of the British and American zones.[9]

The division of Germany was put into effect on 1 July 1945. Because of their unexpectedly rapid advances through central Germany in the final weeks of the war, British and American troops occupied large areas that had been assigned to the Soviet zone of occupation. The redeployment of Western troops prompted many Germans to flee to the West to escape the Soviet takeover of the remainder of the Soviet zone.[10]

The wartime Allies initially worked together under the auspices of the Allied Control Council (ACC) for Germany.[11] Cooperation between the Western Allies and the Soviets ultimately broke down because of disagreements over Germany's political and economic future. In May 1949, the three western occupation zones were merged to form the Federal Republic of Germany (FRG) with a freely elected government. In October, the Soviet zone was proclaimed the German Democratic Republic (GDR), under communist rule.[12]

From the outset, West Germany and the Allies rejected East Germany's legitimacy.[13] The creation of East Germany was deemed a communist/Soviet fait accompli, without a freely or fairly elected government. The FRG regarded German citizenship and rights as applying equally to West and East German citizens. An East German who escaped or was released to the West was automatically granted West German rights including residence, the right to work, and (later) EEC freedom of movement; West German laws were deemed to be applicable in the East. East Germans thus had a powerful incentive to move to the West, where they would enjoy greater freedom and economic prospects.[14] The East German government sought to define the country as a legitimate state in its own right[15] and portrayed West Germany as enemy territory (feindliches Ausland) – a capitalist, semi-fascist state that exploited its citizens, sought to regain the lost territories of the Third Reich, and stood opposed to the peaceful socialism of the GDR.[16]

In the early days of the occupation, the Allies controlled traffic between the zones to manage the flow of refugees and prevent the escape of former Nazi officials and intelligence officers.[17] These controls were gradually lifted in the Western zones, but were tightened between Western and Soviet zones in 1946 to stem a flow of economic and political refugees from the Soviet zone.[18] Between October 1945 and June 1946, 1.6 million Germans left the Soviet zone for the west.[19]

The east–west interzonal border became steadily more tense as the relationship between the Western Allies and the Soviets deteriorated.[20] From September 1947, an increasingly strict regime was imposed on the eastern Soviet zone boundary. The number of Soviet soldiers on the boundary was increased and supplemented with border guards from the newly established East German Volkspolizei ("People's Police"). Many unofficial crossing points were blocked with ditches and barricades.[21] The West Germans also stepped up security with the establishment in 1952 of the Federal Border Protection force of 20,000 men – the Bundesgrenzschutz, or BGS; however, Allied troops (the British in the north, the Americans in the south) retained responsibility for the military security of the border.[22]

The boundary line was nonetheless still fairly easy to cross. Local inhabitants were able to maintain fields on the other side, or even to live on one side and work on the other. Refugees were able to sneak across or bribe the guards, and the smuggling of goods in both directions was rife.[23] The flow of emigrants remained large despite the increase in East German security measures: 675,000 people fled to West Germany between 1949 and 1952.[24]

The relative openness of the border ended abruptly on 26 May 1952, when East Germany implemented a "special regime on the demarcation line", justified as a measure to keep out "spies, diversionists, terrorists and smugglers".[25] The East German move was taken to limit the continuing exodus of its citizens, which threatened the viability of East Germany's economy.[26]

A ploughed strip 10 m (32.8 ft) wide was created along the entire length of the inner German border. An adjoining "protective strip" (Schutzstreifen) 500 m (1,640 ft) wide was placed under tight control. A "restricted zone" (Sperrzone) a further 5 km (3.1 mi) wide was created in which only those holding a special permit could live or work. Trees and brush were cut down along the border to clear lines of sight for the guards and to eliminate cover for would-be crossers. Houses adjoining the border were torn down, bridges were closed, and barbed-wire fencing was put up in many places. Farmers were permitted to work their fields along the border only in daylight hours and under the watch of armed guards, who were authorised to use weapons if their orders were not obeyed.[25]

Border communities on both sides suffered acute disruption. Farms, coal mines, and even houses were split in two by the sudden closure of the border.[27][28] More than 8,300 East German civilians living along the border were forcibly resettled in a programme codenamed "Operation Vermin" (Aktion Ungeziefer).[29] Another 3,000 realised they were about to be expelled from their homes and fled to the West.[24] The seal around the country was expanded in July 1962, when East Germany declared its entire Baltic coast a border zone subject to closures and restrictions.[30]

The border between East and West Berlin was also significantly tightened, although not fully closed; East Germans were still able to cross into West Berlin, which then became the main route by which East Germans migrated to the West.[31] Between 1949 and the building of the Berlin Wall in 1961, an estimated 3.5 million East Germans – a sixth of the entire population – emigrated to the West, most via Berlin.[31] The railways between East Berlin and other important parts of East Germany went through West Berlin, so an easy way of going to West Berlin was by leaving on such a train. This railway configuration could not easily be changed, but a new 125 km (78 mi) long railway was built around West Berlin. Following the completion of the Berlin outer ring in 1961, sealing off the East German border with West Berlin became more feasible, and ultimately became a reality in August of that year.

East Germany decided to upgrade the fortifications in the late 1960s to establish a "modern frontier" that would be far more difficult to cross. Barbed-wire fences were replaced with harder-to-climb expanded metal barriers; directional anti-personnel mines and anti-vehicle ditches blocked the movement of people and vehicles; tripwires and electric signals helped guards to detect escapees; all-weather patrol roads enabled rapid access to any point along the border; and wooden guard towers were replaced with prefabricated concrete towers and observation bunkers.[32]

Construction of the new border system started in September 1967.[33] Nearly 1,300 kilometres (808 mi) of new fencing was built, usually further back from the geographical line than the old barbed-wire fences.[32] The upgrade programme continued well into the 1980s.[34] The new system immediately reduced the number of successful escapes from around a thousand people per year in the mid-1960s to only about 120 per year a decade later.[35]

The introduction of West German Chancellor Willy Brandt's Ostpolitik ("Eastern Policy") at the end of the 1960s reduced tensions between the two German states. It led to a series of treaties and agreements in the early 1970s, most significantly a treaty in which East and West Germany recognised each other's sovereignty and supported each other's applications for UN membership, although East Germans leaving for the West retained the right to claim a West German passport.[36][37] Reunification remained a theoretical objective for West Germany, but in practice that objective was put aside by the West and abandoned entirely by the East.[36][37] New crossing points were established and East German crossing regulations were slightly relaxed, although the fortifications were as rigorously maintained as ever.[38]

In 1988, the East German leadership considered proposals to replace the expensive and intrusive fortifications with a high-technology system codenamed Grenze 2000. Drawing on technology used by the Soviet Army during the Soviet–Afghan War, it would have replaced the fences with sensors and detectors. However, the plan was never implemented.[39][40]

A person attempting to make an illegal crossing of the inner German border around 1980, travelling from east to west, would first come to the "restricted zone" (Sperrzone). This was a 5 kilometres (3.1 mi) wide area running parallel to the border to which access was heavily restricted. Its inhabitants could only enter and leave using special permits, were not permitted to enter other villages within the zone, and were subjected to nighttime curfews.[43][56][57] It was not fenced off, but access roads were blocked by checkpoints.[58]

On the far side of the Sperrzone was the signal fence (Signalzaun), a continuous expanded metal fence 1,185 kilometres (736 mi) long and 2 metres (6.6 ft) high. The fence was lined with low-voltage electrified strands of barbed wire. When the wire was touched or cut, an alarm was activated to alert nearby guards.[59]

On the other side of the signal fence lay the heavily guarded "protective strip" (Schutzstreifen), 500 to 1,000 metres (1,600 to 3,300 ft) wide, which adjoined the border itself.[58] It was monitored by guards stationed in concrete, steel and wooden watchtowers constructed at regular intervals along the entire length of the border. Nearly 700 such watchtowers had been built by 1989;[59] each of the larger ones was equipped with a powerful 1,000-watt rotating searchlight (Suchscheinwerfer) and firing ports to enable the guards to open fire without having to go outside.[60] Their entrances were always positioned facing towards the East German side, so observers in the West could not see guards going in or out. Around 1,000 two-man observation bunkers also stood along the length of the border.[60]

Guard dogs were used to provide an additional deterrent to escapees. Dog runs (Kettenlaufanlagen), consisting of a suspended wire up to 100 metres (330 ft) long to which a large dog was chained, were installed on high-risk sectors of the border. The dogs were occasionally turned loose in temporary pens adjoining gates or damaged sections of the fence.[61]

The guards used an all-weather patrol road (Kolonnenweg, literally "column way") to patrol the border and travel rapidly to the scene of an attempted crossing. It consisted of two parallel lines of perforated concrete blocks running beside the border for about 900 kilometres (560 mi).[62]

Next to the Kolonnenweg was one of the control strips (Kontrollstreifen), a line of bare earth running parallel to the fences along almost the entire length of the border. There were two control strips, both located on the inward-facing sides of the fences. The secondary "K2" strip, 2 metres (6.6 ft) wide, ran alongside the signal fence, while the primary "K6" strip, 6 metres (20 ft) wide, ran along the inside of the fence or wall.[63] In places where the border was vulnerable to escape attempts, the control strip was illuminated at night by high-intensity floodlights (Beleuchtungsanlage), which were also used at points where rivers and streams crossed the border.[61]

Anyone attempting to cross the control strips would leave footprints, which were quickly detected by patrols. This enabled the guards to identify otherwise undetected escape attempts, recording how many individuals had crossed, where escape attempts were being made and at which times of day escapees were active. From this information, the guards were able to determine where and when patrols needed to be increased, where improved surveillance from watchtowers and bunkers was required, and which areas needed additional fortifications.[63]

Anti-vehicle barriers were installed on the other side of the primary control strip. In some locations, Czech hedgehog barricades, known in German as Panzersperre or Stahligel ("steel hedgehogs"), were used to prevent vehicles being used to cross the border. Elsewhere, V-shaped anti-vehicle ditches known as Kraftfahrzeug-Sperrgraben (KFZ-Sperrgraben) were installed along 829 kilometres (515 mi) of the border and were absent only where natural obstacles such as streams, rivers, gullies or thick forests made such barriers unnecessary.[64]

The outer fences were constructed in a number of phases, starting with the initial fortification of the border from May 1952. The first-generation fence was a crudely constructed single barbed-wire fence (Stacheldrahtzaun) which stood between 1.2 and 2.5 metres (3.9 and 8.2 ft) high and was built very close to the actual border line.[65] This was replaced in the late 1950s with parallel rows of more strongly constructed barbed-wire fences, sometimes with concertina wire placed between the fences as an additional obstacle.[66]

A "third-generation" fence, much more solidly constructed, was installed in an ongoing programme of improvements from the late 1960s to the 1980s. The fence line was moved back to create an outer strip between the fence and the actual border. The barbed-wire fences were replaced with a barrier typically 3.2–4.0 metres (10–13 ft) high. It was constructed with expanded metal mesh (Metallgitterzaun) panels. The openings in the mesh were generally too small to provide finger-holds and were very sharp. The panels could not easily be pulled down, as they overlapped, and they could not be cut through with a bolt- or wire-cutter. Nor could they be tunnelled under easily, as the bottom segment of the fences was partially buried in the ground. In a number of places, more lightly constructed fences (Lichtsperren) consisting of mesh and barbed wire lined the border.[61] The fences were not continuous and could be crossed at a number of places. Gates were installed to enable guards to patrol up to the line and to give engineers access for maintenance on the outward-facing side of the barrier.[61]

In some places, villages adjoining the border were fenced with wooden board fences (Holzlattenzaun) or concrete barrier walls (Betonsperrmauern) standing around 3–4 metres (9.8–13.1 ft) high. Windows in buildings adjoining the border were bricked or boarded up, and buildings deemed too close to the border were pulled down. The barrier walls stood along only a small percentage of the border – 29.1 kilometres (18.1 mi) of the total length by 1989.[63]

Anti-personnel mines were installed along approximately half of the border's length starting in 1966; by the 1980s, some 1.3 million mines of various Soviet-made types had been laid.[67] In addition, from 1970 the outer fence was booby-trapped with around 60,000 SM-70 (Splittermine-70) directional anti-personnel mines. They were activated by tripwires connected to the firing mechanism. This detonated a horn-shaped charge filled with shrapnel that was sprayed in one direction along the line of the fence. The device was potentially lethal to a range of around 120 metres (390 ft). The mines were eventually removed by the end of 1984 in the face of international condemnation of the East German government.[68]

Until the late 1960s, the fortifications were constructed almost up to the actual border line. When the third-generation fortifications were constructed, the fences were moved back from between 20 metres (66 ft) to as much as 2 kilometres (1.2 mi). This gave the guards a clear field of fire to target escapees without shots landing in the West and provided a buffer zone where engineers could work on maintaining the outward face of the fence in East German territory. Access to the outer strip was very tightly controlled, to ensure the guards themselves would not be tempted to escape. Although often described by Western sources as a "no-man's land", it was de jure wholly East German territory, and escapees could be arrested or shot.[69] Westerners were prohibited from entering the area and thus could not go to the aid of escapees.

The actual line between West and East Germany was located on the far side of the outer strip. It was marked by granite stones (Grenzsteine) with the letters "DDR" carved on the west-facing edge. Around 2,600 distinctive East German concrete "barber pole" (Grenzsäule or Grenzpfähle) markers were installed just behind the border line at intervals of about 500 metres (1,600 ft). A metal coat of arms of East Germany (Staatsemblem) was fixed to the side of the marker facing West Germany.[32]

On the West German side, there were no fortifications of any kind, nor even any patrol roads in most areas. Warning signs (Grenzschilder) with messages such as Achtung! Zonengrenze! ("Danger! Zonal border!") or Halt! Hier Zonengrenze ("Stop! Zonal border here") notified visitors. Foreign military personnel were restricted from approaching the border to avoid clashes or other unwanted incidents. Signs in English and German provided notifications of the distance to the border to prevent accidental crossings. No such restriction applied to Western civilians, who were free to go up to the border line, and there were no physical obstacles to stop their crossing it.[32]

Following the end of the Second World War, the East German side of the border was guarded initially by the Border Troops (Pogranichnyie Voiska) of the Soviet NKVD (later the KGB). They were supplemented from 1946 by a locally recruited paramilitary force, the German Border Police (Deutsche Grenzpolizei or DGP), before the Soviets handed over full control of the border to the East Germans in 1955/56. In 1961, the DGP was converted into a military force within the National People's Army (Nationale Volksarmee, NVA). The newly renamed Border Troops of the GDR (Grenztruppen der DDR, commonly nicknamed the Grenzer) came under the NVA's Border Command or Grenzkommando. They were responsible for securing and defending the borders with West Germany, Czechoslovakia, Poland, the Baltic Sea and West Berlin. At their peak, the Grenztruppen had up to 50,000 personnel.[79]

Around half of the Grenztruppen were conscripts, a lower proportion than in other branches of the East German armed forces. Many potential recruits were screened out as potentially unreliable; for instance, actively religious individuals or those with close relatives in West Germany. They were all subjected to close scrutiny to assure their political reliability and were given intensive ideological indoctrination.[80]

A special unit of the Stasi secret police worked covertly within the Grenztruppen, posing as regular border guards, between 1968 and 1985, to weed out potential defectors.[81] One in ten officers and one in thirty enlisted men were said to have been recruited by the Stasi as informers. The Stasi regularly interviewed and maintained files on every guard. Stasi operatives were directly responsible for some aspects of security; passport control stations at crossings were manned by Stasi officers wearing Grenztruppen uniforms.[82]

The Grenztruppen were closely watched to ensure they could not take advantage of their inside knowledge to escape across the border. Patrols, watchtowers and observation posts were always manned by two or three guards at a time. They were not allowed to go out of each other's sight in any circumstances. If a guard attempted to escape, his colleagues were under instructions to shoot him without hesitation or prior warning;[82] 2,500 did escape to the West, 5,500 more were caught and imprisoned for up to five years,[83] and a number were shot and killed or injured in the attempt.

The work of the guards involved carrying out repair work on the defences, monitoring the zone from watchtowers and bunkers and patrolling the line several times a day. Border Reconnaissance (Grenzaufklärungszug or GAK) soldiers, an elite reconnaissance force, carried out patrols and intelligence-gathering on the western side of the fence. Western visitors to the border were routinely photographed by the GAKs, who also oversaw work detachments maintaining the fence. The workers would be covered by machine guns to discourage them from attempting to escape.[84]

A number of West German state organisations were responsible for policing the western side of the border. These included the Bundesgrenzschutz (BGS, Federal Border Protection), the Bayerische Grenzpolizei (Bavarian Border Police) and the Bundeszollverwaltung (Federal Customs Administration).[32] West German Army units were not allowed to approach the border without being accompanied by BGS personnel.[2]

The BGS, established in 1951, was responsible for policing a zone 30 kilometres (19 mi) deep along the border.[85] Its 20,000 personnel were equipped with armoured cars, anti-tank guns, helicopters, trucks and jeeps. The BGS had limited police powers within its zone of operations to tackle threats to the peace of the border.[86] Until 1972 in addition to volunteers, conscripts could be drafted for the Compulsory Border Guard Service.[87]

The Bundeszollverwaltung (BZV) was responsible for policing much of the inner German border and manning the West German crossings. Its personnel lived with their families in communities along the border and carried out regular policing tasks in a zone about 10 kilometres (6.2 mi) deep along the border. They had the power to arrest and search suspects in their area of operations with the exception of the section of border in Bavaria.[88] The BZV's remit overlapped significantly with that of the BGS, which led to a degree of feuding between the two agencies.[86]

The Bayerische Grenzpolizei (BGP) was a border police force raised by the Bavarian government to carry out policing duties along the inner German border's 390 kilometres (240 mi) in Bavaria. By the late 1960s, the BGP had six hundred men patrolling its sector of the border, alongside the BZV, BGS and the U.S. Army. Its duties were very similar to those of the BZV, leading to turf wars between the two agencies.[89]

Joint British Army – British Frontier Service patrol near Helmstedt, early 1970s

The British Army conducted only relatively infrequent patrols along its sector of the inner German border, principally for training purposes and symbolic value. By the 1970s, it was carrying out only one patrol a month, rarely using helicopters or ground radar and erecting no permanent observation posts. The British border zone was divided into two sectors covering a total distance of about 650 kilometres (400 mi) along the border.[90] Unlike the Americans, the British did not assign specific units to border duty, but rotated the task between the divisions of the British Army of the Rhine.[91]

The border was also patrolled in the British sector by the British Frontier Service, the smallest of the Western border surveillance organisations. Its personnel served as a liaison between British military and political interests and the German agencies on the border.[92] The BFS was disbanded in 1991 following Germany's reunification.[93]

The United States Army maintained a substantial and continuous military presence at the inner German border throughout the entire period from 1945 to after the end of the Cold War. Regular American soldiers manned the border from the end of the war until they were replaced in 1946 by the United States Constabulary,[94] which was disbanded in 1952 after policing duties were transferred to the German authorities. It was replaced by three dedicated armoured cavalry regiments assigned to provide a permanent defence.[95] The 3rd Armored Cavalry Regiment based at Bamberg, 2nd Armored Cavalry Regiment based at Nuremberg and the 14th Armored Cavalry Regiment based at Fulda – later replaced by the 11th Armored Cavalry Regiment – monitored the border using observation posts, ground and air patrols, countering intrusions and gathering intelligence on Warsaw Pact activities.[96]

There was little informal contact between the two sides; East German guards were under orders not to speak to Westerners.[97] After the initiation of détente between East and West Germany in the 1970s, the two sides established procedures for maintaining formal contacts through 14 direct telephone connections or Grenzinformationspunkte (GIP, "border information points"). They were used to resolve local problems affecting the border, such as floods, forest fires or stray animals.[98]

For many years, the two sides waged a propaganda battle across the border using propaganda signs and canisters of leaflets fired or dropped into each other's territory.[99] West German leaflets sought to undermine the willingness of East German guards to shoot at refugees attempting to cross the border, while East German leaflets promoted the GDR's view of West Germany as a militaristic regime intent on restoring Germany's 1937 borders.[99][100]

During the 1950s, West Germany sent millions of propaganda leaflets into East Germany each year. In 1968 alone, more than four thousand projectiles containing nearly half a million leaflets were fired from East Germany into the West. Another six hundred waterproof East German leaflet containers were recovered from cross-border rivers.[100] The "leaflet war" was eventually ended by mutual agreement in the early 1970s as part of the normalisation of relations between the two German states.[99]

Before 1952, the inner German border could be crossed at almost any point along its length. Fortification of the border resulted in the severing of 32 railway lines, 3 autobahns, 31 main roads, 8 primary roads, about 60 secondary roads and thousands of lanes and cart tracks.[105] The number of crossing points was reduced to three air corridors, three road corridors, two railway lines and two river connections giving transit access to Berlin, plus a handful of additional crossing points for freight traffic.[106]

The situation improved somewhat after the initiation of détente in the 1970s. Additional crossings for so-called kleine Grenzverkehr – "small border traffic", essentially meaning West German day trippers – were opened at various locations along the border. By 1982, there were 19 border crossings: six roads, three autobahns, eight railway lines plus the Elbe river and the Mittellandkanal.[101]

The largest was at Helmstedt-Marienborn on the Hanover–Berlin autobahn (A 2), through which 34.6 million travellers passed between 1985 and 1989.[107] Codenamed Checkpoint Alpha, this was the first of three Allied checkpoints on the road to Berlin.[108] The others were Checkpoint Bravo, where the autobahn crossed from East Germany into West Berlin, and most famous of all, Checkpoint Charlie, the only place where non-Germans could cross from West to East Berlin.[109]

It was not possible to simply drive through the gap in the fence that existed at crossing points, as the East Germans installed high-impact vehicle barriers and mobile rolling barriers that could (and did) kill drivers who attempted to ram them.[110] Vehicles were subjected to rigorous checks to uncover fugitives. Inspection pits and mirrors allowed the undersides of vehicles to be scrutinised. Probes were used to investigate the chassis and even the fuel tank, where a fugitive might be concealed, and vehicles could be partially dismantled in on-site garages. At Marienborn there was even a mortuary garage where coffins could be checked to confirm the occupants really were dead.[111] Passengers were checked and often interrogated about their travel plans and reasons for travelling. The system used simple technology and was slow, relying largely on vast card indexes recording travellers' details. It was effective nonetheless; during the 28-year operation of the Marienborn complex no successful escapes were recorded.[112]

West Germans were able to cross the border relatively freely to visit relatives, but had to go through numerous bureaucratic formalities. East Germans were subjected to far stricter restrictions. Not until November 1964 were they allowed to visit the West at all, and even then only pensioners were allowed. This gave rise to a joke that only in East Germany did people look forward to old age.[113] Younger East Germans were not allowed to travel to the West until 1972, though few did so until the mid-1980s. They had to apply for an exit visa and passport, pay a substantial fee, obtain permission from their employer and undergo an interrogation from the police.[114]

The odds were against successful applications, and only about forty thousand a year were approved. Refusal was often arbitrary, dependent on the goodwill of local officials.[115] Members of the Party elite and cultural ambassadors were frequently given permission to travel, as were essential transport workers. However, they were not permitted to take their families with them.[116]

Until the late 1980s, ordinary East Germans were permitted to travel to the West only on "urgent family business", such as the marriage, serious illness or death of a close relative. In February 1986, the regime relaxed the definition of "urgent family business", which prompted a massive increase in the number of East German citizens able to travel to the West.[117] The relaxation of the restrictions was reported to have been motivated by a desire on the part of the East German leadership to reduce their citizens' desire to travel and shrink the number applying to emigrate. In practice, however, it had exactly the opposite effect.[117]

Crossing the border by rail at Oebisfelde railway station, April 1990

There was no formal legal basis under which a citizen could emigrate from East Germany. In 1975, however, East Germany signed up to the Helsinki Accords, a pan-European treaty to improve relations between the countries of Europe.[118] An increasing number of East German citizens sought to use the Accords' provision on freedom of movement to secure exit visas. By the late 1980s more than a hundred thousand applications for visas were being submitted annually with 15,000–25,000 being granted.[119][120]

The GDR's government nonetheless remained opposed to emigration and sought to dissuade would-be émigrés. The process of applying for an exit permit was deliberately made slow, demeaning, frustrating and often fruitless. Applicants were marginalised, demoted or sacked from their jobs, excluded from universities and subjected to ostracism.[121] They faced the threat of having their children taken into state custody on the grounds that they were unfit to bring up children.[122] The law was used to punish those who continued to apply for emigration; more than ten thousand applicants were arrested by the Stasi between the 1970s and 1989.[123]

A report for the Central Committee's security section noted: "The emigration problem is confronting us with a fundamental problem of the GDR's development. Experience shows that the current repertoire of solutions (improved travel possibilities, expatriation of applicants, etc.) have not brought the desired results, but rather the opposite." The agitation for emigration, the report concluded, "threatens to undermine beliefs in the correctness of the Party's policies".[124]

East German citizens could also emigrate through the semi-secret route of being ransomed by the West German government in a process termed Freikauf (literally, buying freedom).[125] Between 1964 and 1989, 33,755 political prisoners were ransomed. A further 2,087 prisoners were released to the West under an amnesty in 1972. Another 215,000 people, including 2,000 children cut off from their parents, were allowed to leave East Germany to rejoin their families. In exchange, West Germany paid over 3.4 billion marks (DM) – nearly $2.3 billion at 1990 prices – in goods and hard currency.[126]

Those ransomed were valued on a sliding scale, ranging from around 1,875 DM for a manual worker to around 11,250 DM for a doctor. The justification, according to East Germany, was that this was compensation for the money invested by the state in the prisoner's training. For a while, payments were made in kind using goods that were in short supply in East Germany, such as oranges, bananas, coffee and medical drugs. The average prisoner was worth around 4,000 DM worth of goods.[127]

The scheme was highly controversial in the West. Freikauf was denounced by many as human trafficking, but was defended by others as an "act of pure humanitarianism";[128] the West German government budgeted money for Freikauf under the euphemistic heading of "support of special aid measures of an all-German character".[125]

Diagram summarising the numbers of people who succeeded in passing each element of the inner German border system, 1974–79

Between 1950 and 1988, around four million East Germans migrated to the West, 3.454 million before the Berlin Wall's construction in 1961. After that, the number of illegal crossings fell dramatically and continued to fall as the defences were improved. During the 1980s, only about 1% of those who left East Germany did so by escaping across the border – far more emigrated after being granted official permits, fleeing through third countries or by being ransomed by the West German government.[38]

The vast majority of refugees were motivated by economic concerns and sought to improve their living conditions and opportunities by migrating to the West. Events such as the crushing of the 1953 uprising, the imposition of collectivisation and East Germany's final economic crisis in the late 1980s prompted surges in the number of escape attempts.[129]

Attempts to flee across the border were carefully studied and recorded by the GDR authorities to identify possible weak points. These were addressed by strengthening the fortifications in vulnerable areas. At the end of the 1970s, a study was carried out by the East German army to review attempted "border breaches" (Grenzdurchbrüche). It found that 4,956 people had attempted to escape across the border between 1 December 1974 and 30 November 1979. Of those, 3,984 (80.4%) were arrested by the Volkspolizei in the Sperrzone, the outer restricted zone. 205 (4.1%) were caught at the signal fence.[130]

Within the inner security zone (the Schutzstreifen), a further 743 people (15%) were arrested by the guards. 48 (1%) were stopped – i.e. killed or injured – by landmines and 43 (0.9%) by SM-70 directional mines on the fence. A further 67 people (1.35%) were intercepted at the fence (shot and/or arrested). A total of 229  – just 4.6% of attempted escapees, representing less than one in twenty – made it across the fence. Of these, the largest number (129, or 55% of successful escapees) succeeded in unmined sectors. 89 (39% of escapees) managed to cross both the minefields and the fence, but just 12 (6% of the total) succeeded in getting past the SM-70s.[130]

Escape attempts were severely punished by the GDR. From 1953, the regime described the act of escaping as Republikflucht (literally "flight from the Republic"), by analogy with the existing military term Fahnenflucht ("desertion"). A successful escapee was not a Flüchtling ("refugee") but a Republikflüchtiger ("Republic deserter"). Those who attempted to escape were called Sperrbrecher (literally "blockade runners" but more loosely translated as "border violators").[129] Those who helped escapees were not Fluchthelfer ("escape helpers"), the Western term, but Menschenhändler ("human traffickers").[131] Such ideologically coloured language enabled the regime to portray border crossers as little better than traitors and criminals.[132]

Republikflucht became a crime in 1957, punishable by heavy fines and up to three years' imprisonment. Any act associated with an escape attempt – including helping an escapee – was subject to this legislation. Those caught in the act were often tried for espionage as well and given proportionately harsher sentences.[133] More than 75,000 people – an average of more than seven people a day – were imprisoned for attempting to escape across the border, serving an average of one to two years' imprisonment. Border guards who attempted to escape were treated much more harshly and were on average imprisoned for five years.[134]

Escapees used a variety of methods. The great majority crossed on foot, though some took more unusual routes. One of the most spectacular was the balloon escape in September 1979 of eight people from two families in a home-made hot-air balloon. Their flight involved an ascent to more than 2,500 metres (8,200 ft) before landing near the West German town of Naila.[135] The incident inspired the film Night Crossing.

Some of the people who tried to escape were East German guards or soldiers. Some used military vehicles to smash through the Berlin wall.[136]

Other escapees relied more on physical strength and endurance. An escapee on August 26, 1987, used meat hooks to scale the fences,[137] while in 1971 a doctor swam 45 kilometres (28 mi) across the Baltic Sea from Rostock almost to the Danish island of Lolland, before he was picked up by a West German yacht.[138] Another escapee used an air mattress to escape across the Baltic on 2 September 1987.[139]

Mass escapes were rare. One of the few that succeeded took place on 2 October 1961, when 53 people from the border village of Böseckendorf – a quarter of the village's population – escaped en masse, followed by another 13 in February 1963.[140] An unusual mass escape occurred in September 1964 when 14 East Germans, including 11 children, were smuggled across the border in a refrigerated truck. They were able to escape detection by being concealed under the carcasses of slaughtered pigs being transported to the West.[141]

The traffic was not one-way; thousands of people migrated each year from West Germany to the east, motivated by reasons such as marital problems, family estrangement and homesickness.[142] A number of Allied military personnel, including British, French, German and American troops, also defected.[143] By the end of the Cold War, as many as three hundred United States citizens were thought to have defected across the Iron Curtain for a variety of reasons[144] – whether to escape criminal charges, for political reasons or because (as the St. Petersburg Times put it) "girl-hungry GIs [were tempted] with seductive sirens, who usually desert the love-lorn soldier once he is across the border." The fate of such defectors varied considerably. Some were sent straight to labour camps on charges of espionage. Others committed suicide, while a few were able to find wives and work on the eastern side of the border.[145]

From 1945 onwards, unauthorised crossers of the inner German border risked being shot by Soviet or East German guards. The use of deadly force was termed the Schießbefehl ("order to fire" or "command to shoot"). It was formally in force as early as 1948, when regulations concerning the use of firearms on the border were promulgated. A regulation issued to East German police on 27 May 1952 stipulated that "failure to obey the orders of the Border Patrol will be met by the use of arms." From the 1960s through to the end of the 1980s, the border guards were given daily verbal orders (Vergatterung) to "track down, arrest or annihilate violators". The GDR formally codified its regulations on the use of deadly force in March 1982, when the State Border Law mandated that firearms were to be used as the "maximum measure in the use of force" against individuals who "publicly attempt to break through the state border".[146]

The GDR's leadership explicitly endorsed the use of deadly force. General Heinz Hoffmann, the GDR defence minister, declared in August 1966 that "anyone who does not respect our border will feel the bullet." In 1974, Erich Honecker, as Chairman of the GDR's National Defence Council, ordered: "Firearms are to be ruthlessly used in the event of attempts to break through the border, and the comrades who have successfully used their firearms are to be commended."[147]

The Schießbefehl was, not surprisingly, very controversial in the West and was singled out for criticism by the West Germans. The GDR authorities occasionally suspended the Schießbefehl on occasions when it would have been politically inconvenient to have to explain dead refugees, such as during a visit to the GDR by the French foreign minister in 1985.[146] It was also a problem for many of the East German guards and was the motivating factor behind a number of escapes, when guards facing a crisis of conscience defected because of their unwillingness to shoot fellow citizens.[148]

It is still not certain how many people died on the inner German border or who they all were, as the GDR treated such information as a closely guarded secret. But estimates have risen steadily since unification, as evidence has been gathered from East German records. As of 2009, unofficial estimates are up to 1,100 people, though officially released figures give a count from 270 up to 421 deaths.[149]

There were many ways to die on the inner German border. Numerous escapees were shot by the border guards, while others were killed by mines and booby-traps. A substantial number drowned while trying to cross the Baltic and the Elbe river. Not all those killed on the border were attempting to escape. On 13 October 1961, Westfälische Rundschau journalist Kurt Lichtenstein was shot on the border near the village of Zicherie after he attempted to speak with East German farm workers. His death aroused condemnation across the political spectrum in West Germany.[150] The incident prompted students from Braunschweig to erect a sign on the border protesting the killing.[151]

An Italian truck driver and member of the Italian Communist Party, Benito Corghi, was shot at a crossing point in August 1976; the GDR government was severely embarrassed and, unusually, offered an apology.[152] In one notorious shooting on 1 May 1976, a former East German political prisoner, Michael Gartenschläger, who had fled to the West some years before, was ambushed and killed by a Stasi commando squad on the border near Büchen. The Stasi reported that he had been "liquidated by security forces of the GDR".[153]

Twenty-five East German border guards died after being shot from the Western side of the border or were killed by resisting escapees or (often accidentally) by their own colleagues.[154] The East German government described them as "victims of armed assaults and imperialist provocations against the state border of the GDR"[155] and alleged that "bandits" in the West took potshots at guards doing their duty – a version of events uncorroborated by Western accounts of border incidents.

The two sides commemorated their dead in very different ways. Various mostly unofficial memorials were set up on the western side by people seeking to commemorate victims of the border. West Germans such as Michael Gartenschläger and Kurt Lichtenstein were commemorated with signs and memorials, some of which were supported by the government. The death of East German Heinz-Josef Große in 1982 was commemorated annually by demonstrations on the Western side of the border.[156] After the policy of détente was initiated in the 1970s, this became politically inconvenient and state support for border memorials largely ceased.

The taboo in East Germany surrounding escapees meant the great majority of deaths went unpublicised and uncommemorated. However, the deaths of border guards were used for GDR propaganda, which portrayed them as "martyrs". Four stone memorials were erected in East Berlin to mark their deaths.[157] The regime named schools, barracks and other public facilities after the dead guards and used their memorials as places of pilgrimage to signify that (as a slogan put it) "their deaths are our commitment" to maintaining the border. After 1989 the memorials were vandalised, neglected and ultimately removed.[158]

Crowds of West Germans welcome East German Trabant drivers at the Helmstedt crossing, 11 November 1989

The East German government sought to defuse the situation by relaxing the country's border controls with effect from 10 November 1989;[169] the announcement was made on the evening of 9 November 1989 by Politbüro member Günter Schabowski at a somewhat chaotic press conference in East Berlin, who proclaimed the new control regime as liberating the people from a situation of psychological pressure by legalising and simplifying migration. Misunderstanding the note passed to him about the decision to open the border, he announced the border would be opened "immediately, without delay", rather than from the following day as the government had intended. Crucially, it was neither meant to be an uncontrolled opening nor to apply to East Germans wishing to visit the West as tourists.[169] At an interview in English after the press conference, Schabowski told the NBC reporter Tom Brokaw that "it is no question of tourism. It is a permission of leaving the GDR [permanently]."[170]

As the press conference had been broadcast live, within hours, thousands of people gathered at the Berlin Wall demanding that the guards open the gates. The border guards were unable to contact their superiors for instructions and, fearing a stampede, opened the gates. The iconic scenes that followed – people pouring into West Berlin, standing on the Wall and attacking it with pickaxes – were broadcast worldwide.[171]

While the eyes of the world were on the Mauerfall (the fall of the Wall) in Berlin, a simultaneous process of Grenzöffnung (border opening) was taking place along the entire length of the inner German border. Existing crossings were opened immediately. Within the first four days, 4.3 million East Germans – a quarter of the country's entire population – poured into West Germany.[172] At the Helmstedt crossing point on the Berlin–Hanover autobahn, cars were backed up for 65 km (40 mi); some drivers waited 11 hours to cross to the West.[173] The border was opened in stages over the next few months. Many new crossing points were created, reconnecting communities which had been separated for nearly 40 years. BBC correspondent Ben Bradshaw described the jubilant scenes at the railway station of Hof in Bavaria in the early hours of 12 November:

It was not just the arrivals at Hof who wore their emotions on their sleeves. The local people turned out in their hundreds to welcome them; stout men and women in their Sunday best, twice or three times the average age of those getting off the trains, wept as they clapped. "These are our people, free at last," they said ... Those arriving at Hof report people lining the route of the trains in East Germany waving and clapping and holding placards saying: 'We're coming soon'."[174]

Even the East German border guards were not immune to the euphoria. One of them, Peter Zahn, described how he and his colleagues reacted to the opening of the border:

After the Wall fell, we were in a state of delirium. We submitted a request for our reserve activities to be ended, which was approved a few days later. We visited Helmstedt and Braunschweig in West Germany, which would have been impossible before. In the NVA even listening to Western radio stations was punishable and there we were on an outing in the West.[175]

Zonen-Gaby's first banana: West German magazine cover satirising East Germans' banana-buying spree

To the surprise of many West Germans, many of the East German visitors spent their "welcome money" buying great quantities of bananas, a highly prized rarity in the East. For months after the opening of the border, bananas were sold out at supermarkets along the western side of the border as East Germans bought up whole crates, believing supplies would soon be exhausted.[176] The rush for fruit made the banana the unofficial symbol of the changes in East Germany, which some dubbed the "banana revolution".[177]

Some West German leftists protested at what they saw as rampant consumerism by tossing bananas at East Germans coming to visit the West.[178] The easterners' obsession with bananas was famously spoofed by the West German satirical magazine Titanic on the front cover of its November 1989 edition, which depicted "Easterner Gaby (17), happy to be in West Germany: My first banana". Gaby was shown holding a large, peeled cucumber.[179]

The opening of the border had a profound political and psychological effect on the East German public. For many people, the very existence of the GDR, which the SED had justified as the first "Socialist state on German soil", came to be seen as pointless. The state was bankrupt, the economy was collapsing, the political class was discredited, the governing institutions were in chaos and the people were demoralised by the evaporation of the collective assumptions that had underpinned their society for forty years. Membership of the Party collapsed and Krenz himself resigned on 6 December 1989 after only fifty days in office, handing over to the moderate Hans Modrow.[180] The removal of restrictions on travel prompted hundreds of thousands of East Germans to migrate to the West – more than 116,000 did so between 9 November and 31 December 1989, compared with 40,000 for the whole of the previous year.[181]

The new East German leadership initiated "round table" talks with opposition groups, similar to the processes that had led to multi-party elections in Hungary and Poland.[182] When the first free elections were held in East Germany in March 1990, the former SED, which had renamed itself as the Party of Democratic Socialism, was swept from power and replaced by a pro-reunification Alliance for Germany coalition led by the Christian Democratic Union (CDU), Chancellor Kohl's party. Both countries progressed rapidly towards reunification, while international diplomacy paved the way abroad. In July 1990, monetary union was achieved.[183] A Treaty on the establishment of a unified Germany was agreed on in August 1990 and political reunification took place on 3 October 1990.[184]

The abandoned border in Thuringia, December 1990

The border fortifications were progressively torn down and eventually abandoned in the months following its opening. Dozens of new crossings were opened by February 1990, and the guards no longer carried weapons nor made much effort to check travellers' passports.[185] The guards' numbers were rapidly reduced; half were dismissed within five months of the opening.[186] On 1 July 1990 the border was abandoned and the Grenztruppen were officially abolished;[184] all but two thousand of them were dismissed or transferred to other jobs.

The Bundeswehr gave the remaining border guards and other ex-NVA soldiers the immense task of clearing the fortifications, which was completed only in 1994, and rebuilding hundreds of roads and railway lines.[187] A serious complication was the presence of mines along the border. Although the 1.4 million mines laid by the GDR were supposed to have been removed during the 1980s, it turned out that 34,000 were unaccounted for.[188] A further 1,100 mines were found and removed following reunification at a cost of more than 250 million marks,[189] in a programme that was not concluded until the end of 1995.[190]

The border clearers' task was aided unofficially by German civilians from both sides of the former border, who scavenged the installations for fencing, wire and blocks of concrete to use in home improvements. Much of the fence was sold to a West German scrap-metal company. Environmental groups undertook a programme of re-greening the border, planting new trees and sowing grass seed to fill in the clear-cut area along the line.[186]
