Eastern Front (World War I)

Prior to the outbreak of war, German strategy was based almost entirely on the so-called Schlieffen Plan. With the Franco-Russian Agreement in place, Germany knew that war with either of these combatants would result in war with the other, which meant that there would be war in both the west and the east (two-front war). Therefore, the German General Staff, under Alfred von Schlieffen and then Helmuth von Moltke the Younger, planned a quick, all-out ground war on the Western Front to take France and, upon victory, Germany would turn its attention to Russia in the east.

Schlieffen believed Russia would not be ready or willing to move against and attack Germany due to the huge losses of military equipment that Russia had suffered in the Russo-Japanese war of 1904–1905, its low population density and lack of railroads.

Conversely, the Imperial German Navy believed it could be victorious over Britain with Russian neutrality, something which Moltke knew would not be possible.

Border changes in favor of Romania as stipulated in the Treaty of Bucharest

In the immediate years preceding the First World War, the Kingdom of Romania was involved in the Second Balkan War on the side of Serbia, Montenegro, Greece and the Ottoman Empire against Bulgaria. The Treaty of Bucharest, signed on 10 August 1913, ended the Balkan conflict and added 6,960 square kilometers to Romania's territory.[25] Although militarized, Romania decided upon a policy of neutrality at the start of the First World War, mainly due to having territorial interests in both Austria-Hungary (Transylvania and Bukovina) and in Russia (Bessarabia). Strong cultural influences also affected Romanian leanings, however. King Carol I, as a Hohenzollern-Sigmaringen, favoured his Germanic roots, while the Romanian people, influenced by their Orthodox church and Latin-based language, were inclined to join France. Perhaps King Carol's attempts at joining the war on the side of the Central powers would have been fruitful had he not died in 1914, but Romanian disenchantment with Austria-Hungary had already influenced public and political opinion. French endorsement of Romanian action against Bulgaria, and support of the terms of the Treaty of Bucharest was particularly effective at inclining Romania towards the Entente. Furthermore, Russian courting of Romanian sympathies, exemplified by the visit of the Tsar to Constanța on 14 June 1914, signaled in a new era of positive relations between the two countries.[26] Nevertheless, King Ferdinand I of Romania maintained a policy of neutrality, intending to gain the most for Romania by negotiating between competing powers. The result of the negotiations with the Entente was the Treaty of Bucharest (1916), which stipulated the conditions under which Romania agreed to join the war on the side of the Entente, particularly territorial promises in Austria-Hungary: Transylvania, Crișana and Maramureș, the whole Banat and most of Bukovina. According to historian John Keegan, these enticements offered by the Allies were never concrete, for in secret, Russia and France agreed not to honor any conventions when the end of the war came.[27]

The immediate reason for Russia's involvement in the First World War was a direct result of the decisions made by the statesmen and generals during July 1914. The July crisis was the culmination of a series of diplomatic conflicts that took place in the decades prior to 1914, and this is fundamental to an understanding of Russia's position immediately prior to the War. According to D. C. Lieven, Russia was formidable and was able to back up her diplomatic policies with force. One of the most significant factors in bringing Russia to the brink of war was the downfall of her economy.[28] The 20 percent jump in defense expenditure during 1866–77 and in 1871-5 forced them to change their position within Europe and shift the balance of power out of her favour.[29] At the time, Russian infrastructure was backward and the Russian government had to invest far more than its European rivals in structural changes. In addition there were overwhelming burdens of defense, which would ultimately result in an economic downfall for the Russians. This was a major strain on the Russian population, but also served as a direct threat to military expenditure.[30] Thus the only way the Russians could sustain the strains of European war would be to place more emphasis on foreign investment from the French who essentially came to Russia's aid for industrial change.[31] The Franco-Russian Alliance allowed for the Russian defense to grow and aid the European balance of power during the growth of the German Empire's might. Nevertheless, one of the key factors was that of the Russian foreign policy between 1890 and 1914. The Russian army was large, but had poor leadership and poor equipment, and increasingly poor morale until by 1917 it turned against the government.[32]

In order for the Russians to legitimize their war efforts, the government constructed an image of the enemy through state-instituted propaganda. Their main aim was to help overcome the legend of the "invincible" German war machine, in order to boost the morale of civilians and soldiers. Russian propaganda often took the form of showing the Germans as a civilized nation, with barbaric "inhuman" traits. Russian propaganda also exploited the image of the Russian POWs who were in the German camps, again in order to boost the morale of their troops, serving as encouragement to defeat the enemy and to get their fellow soldiers out of German POW camps that were perceived as inhumane.[33]

An element of the Russian propaganda was the Investigate Commission formed in April 1915. It was led by Aleksei Krivtsov, and the study was tasked with the job of studying the legal violations committed by of the Central Powers and then getting this information to the Russian public. This commission published photographs of letters that were allegedly found on fallen German soldiers. These letters document the German correspondents saying to "take no prisoners." A museum was also set up in Petrograd, which displayed pictures that showed how "inhumanly" the Germans were treating prisoners of war.[33]

Austria-Hungary's participation in the outbreak of World War I has been neglected by historians, as emphasis has traditionally been placed on Germany's role as the prime instigator.[34] However, the "spark" that ignited the First World War is attributed to the assassination of Archduke Franz Ferdinand by Gavrilo Princip, which took place on 28 June 1914. Approximately a month later, on 28 July 1914, Austria-Hungary declared war on Serbia. This act led to a series of events that would quickly expand into the First World War; thus, the Habsburg government in Vienna initiated the pivotal decision that would begin the conflict.[34]

The causes of the Great War have generally been defined in diplomatic terms, but certain deep-seated issues in Austria-Hungary undoubtedly contributed to the beginnings of the First World War.[35] The Austro-Hungarian situation in the Balkans pre-1914 is a primary factor in its involvement in the war. The movement towards South Slav unity was a major problem for the Habsburg Empire, which was facing increasing nationalist pressure from its multinational populace. As Europe's third largest state, the Austro-Hungarian monarchy was hardly homogeneous; comprising over fifty million people and eleven nationalities, the Empire was a conglomeration of a number of diverse cultures, languages, and peoples.[36]

Specifically, the South Slavic people of Austria-Hungary desired to amalgamate with Serbia in an effort to officially solidify their shared cultural heritage. Over seven million South Slavs lived inside the Empire, while three million lived outside it.[37] With the growing emergence of nationalism in the twentieth century, unity of all South Slavs looked promising. This tension is exemplified by Conrad von Hötzendorf's letter to Franz Ferdinand:

The unification of the South Slav race is one of the powerful national movements which can neither be ignored nor kept down. The question can only be, whether unification will take place within the boundaries of the Monarchy – that is at the expense of Serbia's independence – or under Serbia's leadership at the expense of the Monarchy. The cost to the Monarchy would be the loss of its South Slav provinces and thus of almost its entire coastline. The loss of territory and prestige would relegate the Monarchy to the status of a small power.[38]

The annexation of Bosnia-Herzegovina in 1908 by Austrian foreign minister Baron von Aehrenthal in an effort to assert domination over the Balkans inflamed Slavic nationalism and angered Serbia. Bosnia-Herzegovina became a "rallying cry" for South Slavs, with hostilities between Austria-Hungary and Serbia steadily increasing.[39] The situation was ripe for conflict, and when the Serbian nationalist Gavrilo Princip assassinated Austrian imperial heir, Franz Ferdinand, these longstanding hostilities culminated into an all-out war.

The Allied Powers wholeheartedly supported the Slavs' nationalistic fight. George Macaulay Trevelyan, a British historian, saw Serbia's war against Austria-Hungary as a "war of liberation" that would "free South Slavs from tyranny."[40] In his own words: "If ever there was a battle for freedom, there is such a battle now going on in Southeastern Europe against Austrian and Magyar. If this war ends in the overthrow of the Magyar tyranny, an immense step forward will have been taken toward racial liberty and European peace."[41]

Hindenburg at Tannenberg,

An engagement in Hungary

The war in the east began with the Russian invasion of East Prussia on 17 August 1914 and the Austro-Hungarian province of Galicia.[47] The first effort quickly turned to a disastrous defeat following the Battle of Tannenberg in August 1914.[48] A second Russian incursion into Galicia was completely successful, with the Russians controlling almost all of that region by the end of 1914, routing four Austrian armies in the process. Under the command of Nikolai Ivanov, Nikolai Ruzsky and Aleksei Brusilov, the Russians won the Battle of Galicia in September and began the Siege of Przemyśl, the next fortress on the road towards Kraków.[49]

This early Russian success in 1914 on the Austro-Russian border was a reason for concern to the Central Powers and caused considerable German forces to be transferred to the East to take pressure off the Austrians, leading to the creation of the new German Ninth Army. The Austro-Hungarian government accepted the Polish proposal of establishing the Supreme National Committee as the Polish central authority within the Empire, responsible for the formation of the Polish Legions, an auxiliary military formation within the Austro-Hungarian army. At the end of 1914, the main focus of the fighting shifted to central part of Russian Poland, west of the river Vistula.[50] The October Battle of the Vistula River and the November Battle of Łódź brought little advancement for the Germans, but at least kept the Russians at a safe distance.[51]

The Russian and Austro-Hungarian armies continued to clash along the Carpathian Front throughout the winter of 1914–1915. Przemysl fortress managed to hold out deep behind enemy lines throughout this period, with the Russians bypassing it in order to attack the Austro-Hungarian troops further to the west. They made some progress, crossing the Carpathian Mountains in February and March 1915, but then the German relief helped the Austrians stop further Russian advances. In the meantime, Przemysl was almost entirely destroyed and the Siege of Przemysl ended in a defeat for the Austrians.[52][53]

After the Battle of Sarikamish, the Russo-Turkish front quickly turned in favor of Russian forces. The Turks were concerned with reorganizing their army and also fighting the massive Allied armada that landed in Galipoli. Meanwhile, Russia was preoccupied with other armies on the Eastern Front. However, the appointment of Grand Duke Nicholas Nikolaevich as Viceroy and Commander in the Caucasus in September 1915 revived the situation of the Russo-Turkish front.

When the Allies withdrew from Gallipoli in December, the Caucasus Army's Chief of Staff General Nikolai Yudenich believed Turkish forces would take action against his army. This concern was legitimate: Bulgaria's entry into the war as Germany's ally in October caused serious alarm, as a land route from Germany to Turkey was now open and would allow for an unrestricted flow of German weapons to the Turks.[55] A "window of opportunity" appeared that would allow the Russians to destroy the Turkish Third Army, as the British required assistance in Mesopotamia (now modern day Iraq). Britain's efforts to besiege Baghdad had been halted at Ctesiphon, and they were forced to retreat. This led to an increasing number of attacks by Turkish forces. The British requested the Russians to attack in an attempt to distract the Turks, and Yudenich agreed. The resulting offensive began on 10 January 1916.[56]

This offensive was unanticipated by the Turks, as it was in the middle of winter. The Turkish situation was exacerbated by the absences of Third Army's commander Kamil Pasha and Chief of Staff Major Guse. Coupled with an imbalance of forces – the Russians had 325 000 troops, while the Turks only 78 000 – the situation appeared grim for the Central Powers.[56] After three months of fighting, the Russians captured the city of Trabzon on 18 April 1916.

Brusilov offensive

The Italian operations during 1916 had one extraordinary result: Austrian divisions were pulled away from the Russian southern front. This allowed the Russian forces to organize a counter-offensive. The Brusilov offensive was a large tactical assault carried out by Russian forces against Austro-Hungarian forces in Galicia. General Aleksei Brusilov believed victory against the Central Powers was possible if close attention was paid to preparation. Brusilov suggested that the Russians should attack on a wide front, and to position their trenches a mere 75 yards (69 m) away from Austrian trenches.[57]

Brusilov's plan worked impeccably. The Russians outnumbered the Austrians 200,000 to 150,000, and held a considerable advantage in guns, with 904 large guns to 600. Most importantly innovative new tactics similar to those independently invented by Erwin Rommel were used to perform quick and effective close-range surprise attacks that allowed a steady advance.[58] The Russian Eighth Army overwhelmed the Austrian Fourth and pushed on to Lutsk, advancing 40 miles (64 km) beyond the starting position. Over a million Austrians were lost, with over 500,000 men killed or taken prisoner by mid-June.[58]

Although the Brusilov offensive was initially successful, it slowed down considerably. An inadequate number of troops and poorly maintained supply lines hindered Brusilov's ability to follow up on the initial victories in June. The Brusilov offensive is considered to be the greatest Russian victory of the First World War.[21]^: 52 Although it cost the Russians half a million casualties, the offensive successfully diverted substantial forces of the Central Powers from the Western front, and persuaded Romania to join the war, diverting even more Central Powers forces to the East.[59]

The development of the Russian armament industry was mainly supported by French investors before the war. The Russian High Command saw the reason for the losses of the war in the lack of munitions. Most of these supplies were lost when advancing German troops occupied the fortifications. The production of munitions in the Tsarist empire was difficult, confidence in private enterprise among army personnel was low, and little capital was invested in the industry until 1916. About fifty percent of Russian ammunition requirements were supplied by Britain and the USA. As the Western companies were also responsible for supplying the needs of the Western Front, only a small proportion of the required quantity could be transported to Russia. In the following year, the Russian armaments industry was able to increase its production figures by a factor of two and a half and, despite the insufficient help of the Allies to cover the needs of the Russian army.

It is no exaggeration to say that Roumania may be the turning-point of the campaign. If the Germans fail there it will be the greatest disaster inflicted upon them. Afterwards it will only be a question of time. But should Germany succeed I hesitate to think what the effect will be on the fortunes of the campaign. … and yet no one seems to have thought it his particular duty to prepare a plan...

British poster, welcoming Romania's decision to join the Entente

Up until 1916, the Romanians followed the tides of war with interest, while attempting to situate themselves in the most advantageous position. French and Russian diplomats had begun courting the Romanians early on, but persuasion tactics gradually intensified. For King Ferdinand to commit his force of half a million men, he expected the Allies to offer a substantial incentive.[61] Playing on Romanian anti-Hungarian sentiment the Allies promised the Austria-Hungarian territory of Ardeal (Transylvania) to Romania. Transylvanian demographics strongly favoured the Romanians. Romania succumbed to Allied enticement on 18 August 1916.[62] Nine days later, on 27 August, Romanian troops marched into Transylvania.

Romania's entry into the war provoked major strategic changes for the Germans. In September 1916, German troops were mobilized to the Eastern Front. Additionally, the German Chief of the General Staff, General Erich Von Falkenhayn was forced to resign from office though his successor appointed him to command the combined Central Powers forces against Romania, along with General August von Mackensen. Kaiser Wilhelm II immediately replaced Falkenhayn with Paul von Hindenburg.[63] Von Hindenburg's deputy, the more adept Erich Ludendorff, was given effective control of the army and ordered to advance on Romania. On 3 September, the first troops of the Central Powers marched into Romanian territory. Simultaneously, the Bulgarian Air Force commenced an incessant bombing of Bucharest.[64] In an attempt to relieve some pressure, French and British forces launched a new offensive known as the Battle of the Somme, while the Brusilov offensive continued in the East.

It is certain that so relatively small a state as Rumania had never before been given a role so important, and, indeed, so decisive for the history of the world at so favorable a moment. Never before had two Great Powers like Germany and Austria found themselves so much at the mercy of the military resources of a country which had scarcely one twentieth of the population of the two great states. Judging by the military situation, it was to be expected that Rumania had only to advance where she wished to decide the world war in favor of those Powers which had been hurling themselves at us in vain for years. Thus everything seemed to depend on whether Rumania was ready to make any sort of use of her momentary advantage.

— Paul von Hindenburg, Out of My Life[65]

The entrance of Romania into the war was disconcerting for von Hindenburg. On 15 September, Paul von Hindenburg issued the following order, stating that: "The main task of the Armies is now to hold fast all positions on the Western, Eastern, Italian and Macedonian Fronts, and to employ all other available forces against Rumania."[66] Fortunately for the Central Powers, the quantity and quality of the Romanian Army was overestimated. Although numbering half a million men, the Romanian Army suffered from poor training and a lack of appropriate equipment.

The initial success of the Romanian Army in Austria-Hungarian territory was quickly undermined by the Central Powers. German and Austro-Hungarian troops advanced from the north, while Bulgarian-Turkish-German forces marched into Romania from the south. Although thought to be a tactical blunder by contemporaries, the Romanians opted to mount operations in both directions.[67] By the middle of November the German force passed through the Carpathians, suffering significant casualties due to determined Romanian resistance. By 5 December, Bulgarian troops had crossed the Danube and were approaching the capital, Bucharest. At the same time as the Austro-Hungarian troops moved east, and as the Bulgarians marched north, the Turks had sent in two army divisions by sea to the Dobruja from the east.[68] Eventually, the Romanian forces were pushed back behind the Siret in northern Moldavia. They received help from the Allies, notably from France which sent a military mission of more than a thousand officers, health and support staff.

The Act of 5 November 1916 was proclaimed then to the Poles jointly by the Emperors Wilhelm II of Germany and Franz Joseph of Austria-Hungary. This act promised the creation of the Kingdom of Poland out of territory of Congress Poland, envisioned by its authors as a puppet state controlled by the Central Powers. The origin of that document was the dire need to draft new recruits from German-occupied Poland for the war with Russia. Following the Armistice of 11 November 1918 ending the World War I, in spite of the previous initial total dependence of the kingdom on its sponsors, it ultimately served against their intentions as the cornerstone proto state of the nascent Second Polish Republic, the latter conposed also of territories never intended by the Central Powers to be ceded to Poland.

By January 1917, the ranks of the Romanian army had been significantly thinned. Roughly 150,000 Romanian soldiers had been taken prisoner, 200,000 men were dead or wounded, and lost two thirds of their country, including the capital.[69] Importantly, the Ploiești oilfields, the only significant source of oil in Europe west of the Black Sea, had been destroyed before they were abandoned to the Central Powers.

The Russian February Revolution aimed to topple the Russian monarchy and resulted in the creation of the Provisional Government. The revolution was a turning point in Russian history, and its significance and influence can still be felt in many countries today.[70] Although many Russians wanted a revolution, no one had expected it to happen when it did – let alone how it did.

On International Women's Day, Thursday, 23 February 1917/8 March 1917, as many as 90,000 female workers in the city of Petrograd left their factory jobs and marched through the streets, shouting "Bread", "Down with the autocracy!" and "Stop the War!" These women were tired, hungry, and angry,[71] after working long hours in miserable conditions to feed their families because their menfolk were fighting at the front. They were not alone in demanding change; more than 150,000 men and women took to the streets to protest the next day.

By Saturday, 25 February, the city of Petrograd was essentially shut down. No one was allowed to work or wanted to work.[72] Even though there were a few incidents of police and soldiers firing into the crowds, those groups soon mutinied and joined the protesters.[73] Tsar Nicholas II, who was not in Petrograd during the revolution, heard reports of the protests but chose not to take them seriously. By 1 March, it was obvious to everyone except the czar himself, that his rule was over. On 2 March it was made official.[74]

In early July 1917, on the Romanian front, a relatively small area, there was one of the largest concentrations of combat forces and means known during the conflagration: nine armies, 80 infantry divisions with 974 battalions, 19 cavalry divisions with 550 squadrons and 923 artillery batteries, whose effectives numbered some 800,000 men, with about one million in their immediate reserve. The three great battles, decisive for the Romanian nation's destiny, delivered at Mărăști, Mărășești and Oituz represented a turning point in the world war on the Eastern front. These battles, named by the localities and zones where they took place, were fought approximately on the front alignment stabilized in early 1917, which the conflicting sides had thoroughly consolidated for half a year.[75]

Between late July and early September, the Romanian Army fought the battles of Mărăști, Mărășești and Oituz, managing to stop the German-Austro-Hungarian advance, inflicting heavy losses in the process and winning the most important Allied victories on the Eastern Front in 1917.

As a result of these operations, the remaining Romanian territories remained unoccupied, tying down nearly 1,000,000 Central Powers troops and prompting The Times to describe the Romanian front as "The only point of light in the East".

On 7 May 1918, in light of the existing politico-military situation, Romania was forced to conclude the Treaty of Bucharest with the Central Powers, imposing harsh conditions on the country but recognizing its union with Bessarabia. Alexandru Marghiloman became the new German-sponsored Prime Minister. King Ferdinand, however, refused to sign the treaty.

The Germans were able to repair the oil fields around Ploiești and by the end of the war had pumped a million tons of oil. They also requisitioned two million tons of grain from Romanian farmers. These materials were vital in keeping Germany in the war to the end of 1918.[76]

By September 1917, just months after the February Revolution, Lenin believed the Russian people were ready for another revolution, this time on Marxist principles.[77] On 10 October, at a secret meeting of the Bolshevik party leaders, Lenin used all his power to convince the others that it was time for armed insurrection. Troops who were loyal to the Bolsheviks took control of the telegraph stations, power stations, strategic bridges, post offices, train stations, and state banks.[78]

Petrograd was officially in the hands of the Bolsheviks, who greatly increased their organization in factory groups and in many barracks throughout Petrograd. They concentrated on devising a plan for overturning the Provisional Government, with a coup d'état.[79] On 24 October, Lenin emerged from hiding in a suburb, entered the city, set up his headquarters at the Smolny Institute and worked to complete his three-phase plan. With the main bridges and the main railways secured, only the Winter Palace, and with it the Provisional Government, remained to be taken. On the evening of 7 November, the troops that were loyal to the Bolsheviks infiltrated the Winter Palace. After an almost bloodless coup, the Bolsheviks were the new leaders of Russia.[79] Lenin announced that the new regime would end the war, abolish all private land ownership, and create a system for workers' control over the factories.

After the disintegration of the Russian imperial army and navy in 1917, the Council of People's Commissars headed by Leon Trotsky set about creating a new army. By a decree on 28 January 1918 the council created the Workers' and Peoples' Red Army; it began recruitment on a voluntary basis, but on 22 April, the Soviet government made serving in the army compulsory for anyone who did not employ hired labor. While the majority of the army was made up of workers and peasants, many of the Red Army's officers had served a similar function in the imperial army before its collapse.[81]

With the German Army just 85 miles (137 km) from the Russian capital Petrograd (St. Petersburg) on 3 March 1918, the Treaty of Brest-Litovsk was signed and the Eastern Front ceased to be a war zone. While the treaty was practically obsolete before the end of the year, it did provide some relief to the Bolsheviks, who were embroiled in a civil war, and affirmed the independence of Ukraine. However, Estonia and Latvia were intended to become a United Baltic Duchy to be ruled by German princes and German nobility as fiefdoms under the German Kaiser. A rump Polish state was also foreeseen on the formerly Russian territories. Finland's sovereignty had already been declared in December 1917, and accepted by most nations, including France and Russia, but not by the United Kingdom and the United States.

The empire of Austria lost approximately 60% of its territory as a result of the war, and evolved into a smaller state with a small homogeneous population of 6.5 million people. With the loss, Vienna was now an imperial capital without an empire to support it. The states that were formed around Austria feared the return of the Austro-Hungarian Empire and put measures into place to prevent it from re-forming.[91]

Czechoslovakia was created through the merging of the Czech provinces of Bohemia and Moravia, previously under Austrian rule, united with Slovakia and Ruthenia, which were part of Hungary. Although these groups had many differences between them, they believed that together they would create a stronger state. The new country was a multi-ethnic state. The population consisted of Czechs (51%), Slovaks (16%), Germans (22%), Hungarians (5%) and Rusyns (4%), with other ethnic groups making up 2%.[92] Many of the Germans, Hungarians, Ruthenians and Poles[93] and some Slovaks, felt oppressed because the political elite did not generally allow political autonomy for minority ethnic groups. The state proclaimed the official ideology that there are no Czechs and Slovaks, but only one nation of Czechoslovaks (see Czechoslovakism), to the disagreement of Slovaks and other ethnic groups. Once a unified Czechoslovakia was restored after World War II the conflict between the Czechs and the Slovaks surfaced again.

After the war Hungary was severely disrupted by the loss of 72% of its territory, 64% of its population and most of its natural resources. The loss of territory was similar to that of Austria after the breaking up the Austria-Hungary territory. They lost the territories of Transylvania, Slovakia, Croatia, Slavonia, Syrmia, and Banat.[91]

Italy incorporated the regions of Trieste and South Tyrol from Austria.

The creation of a free and Independent Poland was one of Wilson's fourteen points. At the end of the 18th century the state of Poland was broken apart by Prussia, Russia, and Austria. During the Paris Peace Conference, 1919, the Commission on Polish Affairs was created which recommended there be a passageway across West Prussia and Posen, in order to give Poland access to the Baltic through the port of Danzig at the mouth of the Vistula River. The creation of the state of Poland would separate East Prussia from the rest of Germany, as it was before the Partitions of Poland. Poland also received Upper Silesia. British Foreign Secretary Lord Curzon proposed Poland's eastern border with Russia. Neither the Soviet Russians nor the Polish were happy with the demarcation of the border.[91]

The state of Romania was enlarged greatly after the war. As a result of the Paris peace conference Romania kept the Dobrudja and Transylvania. Between the states of Yugoslavia, Czechoslovakia, and Romania an alliance named the Little Entente was formed. They worked together on matters of foreign policy in order to prevent a Habsburg restoration.[91]

Initially Yugoslavia began as the Kingdom of Serbs, Croats and Slovenes. The name was changed to Yugoslavia in 1929. The State secured its territory at the Paris peace talks after the end of the war. The state suffered from many internal problems because of the many diverse cultures and languages within the state. Yugoslavia was divided on national, linguistic, economic, and religious lines.[91]
