Epirus

Epirus was part of the Proto-Greek area according to linguist Vladimir I. Georgiev.

Mycenaean sites in the region of Epirus.

In the Neolithic period Epirus was populated by seafarers along the coast and by shepherds and hunters from the southwestern Balkans who brought with them the Greek language. These people buried their leaders in large mounds containing shaft graves. Similar burial chambers were subsequently used by the Mycenaean civilization, suggesting that the founders of Mycenae may have come from Epirus and central Albania. Epirus itself remained culturally backward during this time, but Mycenaean remains have been found at two religious shrines of great antiquity in the region: the Oracle of the Dead on the Acheron River, familiar to the heroes of Homer’s Odyssey, and the Oracle of Zeus at Dodona, to whom Achilles prayed in the Iliad.[1]

In the Middle Bronze Age, Epirus was inhabited by the same nomadic Hellenic tribes that went on to settle in the rest of Greece.[12] Aristotle considered the region around Dodona to have been part of Hellas and the region where the Hellenes originated.[13][14] According to Bulgarian linguist Vladimir I. Georgiev, Epirus was part of the Proto-Greek linguistic area during the Late Neolithic period.[15] By the early 1st millennium BC, all fourteen Epirote tribes including the Chaonians in northwestern Epirus, the Molossians in the centre and the Thesprotians in the south, were speakers of a strong west Greek dialect.[1][2][16]

Regions of mainland Greece and environments in antiquity.

Geographically on the edge of the Greek world, Epirus remained for the most part outside the limelight of Greek history until relatively late, much like the neighbouring Greek regions of Macedonia, Aetolia, and Acarnania, with which Epirus had political, cultural, linguistic and economic connections.[17] Unlike most other Greeks of this time, who lived in or around city-states, the inhabitants of Epirus lived in small villages and their way of life was foreign to that of the poleis of southern Greece.[1][18] Their region lay on the periphery of the Greek world[1] and was far from peaceful; for many centuries, it remained a frontier area contested with the Illyrian peoples to the north. However, Epirus had a far greater religious significance than might have been expected given its geographical remoteness, due to the presence of the shrine and oracle at Dodona – regarded as second only to the more famous oracle at Delphi.

The Epirotes, speakers of a Northwest Greek dialect, different from the Dorian of the Greek colonies on the Ionian islands, and bearers of mostly Greek names, as evidenced by epigraphy, seem to have been regarded with some disdain by some classical writers. The 5th-century BC Athenian historian Thucydides describes them as "barbarians" in his History of the Peloponnesian War,[19] as does Strabo in his Geography.[20] Other writers, such as Herodotus,[21] Dionysius of Halicarnassus,[22] Pausanias,[23] and Eutropius,[24] describe them as Greeks. Similarly, Epirote tribes/states are included in the Argive and Epidaurian lists of the Greek Thearodokoi (hosts of sacred envoys).[25] Plutarch mentions an interesting element of Epirote folklore regarding Achilles: In his biography of King Pyrrhus, he claims that Achilles "had a divine status in Epirus and in the local dialect he was called Aspetos" (meaning unspeakable, unspeakably great, in Homeric Greek).[26][27]

Beginning in 370 BC, the Molossian Aeacidae dynasty built a centralized state in Epirus and began expanding their power at the expense of rival tribes.[1] The Aeacids allied themselves with the increasingly powerful kingdom of Macedon, in part against the common threat of Illyrian raids,[28] and in 359 BC the Molossian princess Olympias, niece of Arybbas of Epirus, married King Philip II of Macedon.[1] She was to become the mother of Alexander the Great.

On the death of Arybbas, Alexander of Epirus succeeded to the throne and the title King of Epirus in 334 BC. He invaded Italy, but was killed in battle by a Lucanian in the Battle of Pandosia against several Italic tribes 331 BC.[1][29] Aeacides of Epirus, who succeeded Alexander, espoused the cause of Olympias against Cassander, but was dethroned in 313 BC. His son Pyrrhus came to throne in 295 BC, and for six years fought against the Romans and Carthaginians in southern Italy and Sicily. The high cost of his victories against the Romans gave Epirus a new, but brief, importance, as well as a lasting contribution to the Greek language with the concept of a "Pyrrhic victory". Pyrrhus nonetheless brought great prosperity to Epirus, building the great theater of Dodona and a new suburb at Ambracia (now modern Arta), which he made his capital.[1]

The Aeacid dynasty ended in 232 BC, but Epirus remained a substantial power, unified under the auspices of the Epirote League as a federal state with its own parliament, or synedrion.[1] However, it was faced with the growing threat of the expansionist Roman Republic, which fought a series of wars against Macedon. The League steered an uneasy neutral course in the first two Macedonian Wars but split in the Third Macedonian War (171–168 BC), with the Molossians siding with the Macedonians and the Chaonians and Thesprotians siding with Rome.[1] The outcome was disastrous for Epirus; Molossia fell to Rome in 167 BC and 150,000 of its inhabitants were enslaved.[1]

The region of Epirus was placed under the senatorial province of Achaea in 27 BC, with the exception of its northernmost part, which remained part of the province of Macedonia.[30] Under Emperor Trajan, sometime between 103 and 114 AD, Epirus became a separate province, under a procurator Augusti. The new province extended from the Gulf of Aulon (Vlorë) and the Acroceraunian Mountains in the north to the lower course of the Acheloos River in the south, and included the northern Ionian Islands of Corfu, Lefkada, Ithaca, Cephallonia, and Zakynthos.[30]

The Roman provinces in the Balkans including Epirus Vetus and Epirus Nova, ca. 400 AD.

Probably during the provincial reorganization by Diocletian (r. 284–305), the western portion of the province of Macedonia along the Adriatic coast was split off into the province of New Epirus (Latin: Epirus Nova). Although this territory was not traditionally part of Epirus proper as defined by the ancient geographers, and was historically inhabited by Illyrian tribes and Greeks, the name reflects the fact that under Roman rule, the area had been subject to increasing Hellenization and settlement by Epirote tribes from the south.[30]

The two Epirote provinces became part of the Diocese of Moesia, until it was divided in ca. 369 into the dioceses of Macedonia and Dacia, when they became part of the former.[31] In the 4th century, Epirus was still a stronghold of paganism, and was aided by Emperor Julian (r. 361–363) and his praetorian prefect Claudius Mamertinus through reduction in taxes and the rebuilding of the provincial capital, Nicopolis.[32] According to Jordanes, in 380 the Visigoths raided the area.[32] With the division of the Empire on the death of Theodosius I in 395, Epirus became part of the Eastern Roman or Byzantine Empire.[32] In 395–397, the Visigoths under Alaric plundered Greece. They remained in Epirus for a few years, until 401, and again in 406–407, during Alaric's alliance with the Western Roman generalissimo Stilicho in order to wrest the Eastern Illyricum from the Eastern Empire.[32]

Ruins of Buthrotum

The Synecdemus of Hierocles, composed in ca. 527/8 AD but probably reflecting the situation in the first half of the 5th century, reports 11 cities for Old Epirus (Ancient Greek: Παλαιὰ Ἤπειρος, Latin: Epirus Vetus): the capital Nicopolis, Dodona, Euroea, Hadrianopolis, Appon, Phoenice, Anchiasmos, Buthrotum, Photike, Corfu Island, and Ithaca Island.[33] New Epirus, with capital at Dyrrhachium, comprised 9 cities.[32] From 467 on, the Ionian Islands and the coasts of Epirus became subject to raids by the Vandals, who had taken over the North African provinces and established their own kingdom centred on Carthage. The Vandals notably seized Nicopolis in 474 as a bargaining chip in their negotiations with Emperor Zeno, and plundered Zakynthos, killing many of its inhabitants and ferrying off others into slavery.[34] Epirus Nova became a battleground in the rebellions of the Ostrogoths after 479.[34] In 517, a raid of the Getae or Antae reached Greece, including Epirus Vetus.[34] The claim of Procopius of Caesarea in his Secret History, that under Justinian I (r. 527–565) the entirety of the Balkan provinces was raided by barbarians every year, is considered rhetorical hyperbole by modern scholars; only a single Slavic raid to the environs of Dyrrhachium, in 548/9, has been documented.[34] Procopius further reports that in 551, in an attempt to interdict the Byzantines' lines of communication with Italy during the Gothic War, the Ostrogoth king Totila sent his fleet to raid the shores of Epirus.[35] In response to these raids, and to repair the damage done by two destructive earthquakes in 522, Justinian initiated a wide-ranging programme of reconstruction and re-fortification: Hadrianopolis was rebuilt, albeit in reduced extent, and renamed Justinianopolis, while Euroea was moved further inland (traditionally identified with the founding of Ioannina), while Procopius claims that no less than 36 smaller fortresses in Epirus Vetus—most of them not identifiable today—were either rebuilt or built anew.[35]

In the late 6th century, much of Greece, including Epirus, fell under the control of the Avars and their Slavic allies. This is placed by the Chronicle of Monemvasia in the year 587, and is further corroborated by evidence that several sees were abandoned by their bishops by 591. Thus in c. 590 the bishop, clergy and people of Euroea fled their city, carrying with them the relics of their patron saint, St. Donatus, to Cassiope in Corfu.[36]

Of the various Slavic tribes, only the Baiounitai, first attested c. 615, are known by name, giving their name to their region of settlement: "Vagenetia".[36] Based on the density of the Slavic toponyms in Epirus, the Slavs must have settled in the region, although the extent of this settlement is unclear.[37] Slavic toponyms occur mainly in the mountainous areas of the interior and the coasts of the Gulf of Corinth, indicative of the fact that this was the avenue used by most of the Slavs who crossed the Gulf into the Peloponnese. With the exception of some few toponyms on Corfu, the Ionian Islands seem to not have been affected by Slavic settlement. The linguistic analysis of the toponyms reveals that they date mostly to the early wave of Slavic settlement at the turn of the 6th/7th centuries. Due to scarcity of textual evidence, it is unclear how much the area was affected by the second wave of Slavic migration, which began in the middle of the 8th century due to Bulgar pressure in the northern Balkans.[38] Slavic toponyms are nearly lacking in the mountains of Labëria (on the Kurvelesh plateau), in the Ionian coast where today Lab Albanian villages neighbour with the Greek-speaking ones, therefore it can be assumed that the expansion of the Slavs had not reach this region.[39]

As in eastern Greece, the restoration of Byzantine rule seems to have proceeded from the islands, chiefly Cephallonia, which was certainly under firm Imperial control in c. 702, when Philippicus Bardanes was banished there. The gradual restoration of Imperial rule is evidenced further from the participation of local bishops in councils in Constantinople: whereas only the bishop of Dyrrhachium participated in the Ecumenical Councils of 680/1 and 692, a century later the bishops of Dyrrhachium, Nicopolis, Corfu, Cephallonia, and Zakynthos are attested in the Second Council of Nicaea in 787.[40] In about the middle of the 8th century, the Theme of Cephallenia was established, but at least initially it was more oriented towards restoring Byzantine control over the Ionian and Adriatic seas, combating Saracen piracy, and securing communications with the remaining Byzantine possessions in Italy, rather than any systematic effort at subduing the Epirote mainland.[40] Nevertheless, following the onset of the Muslim conquest of Sicily in 827, the Ionian became particularly exposed to Arab raids.[41]

The 9th century saw great progress in the restoration of Imperial control in the mainland, as evidenced by the participation of the bishops of Ioannina, Naupaktos, Hadrianopolis, and Vagenetia (evidently by now organized as a Sklavinia under imperial rule) in the Ecumenical Councils of 869/70 and 879/80.[41] The Byzantine recovery resulted in an influx of Greeks from southern Italy and Asia Minor into the Greek interior, while remaining Slavs were Christianized and Hellenized.[42] The eventual success of the Hellenization campaign also suggests a continuity of the original Greek population, and that the Slavs had settled among many Greeks, in contrast to areas further north, in what is now Bulgaria and the former Yugoslavia, as those areas could not be Hellenized when they were recovered by the Byzantines in the early 11th century.[42] Following the great naval victory of admiral Nasar in 880, and the beginning of the Byzantine offensive against the Arabs in southern Italy in the 880s, the security situation improved and the Theme of Nicopolis was established, most likely after 886.[41][43] As the ancient capital of Epirus had been laid waste by the Slavs, the capital of the new theme became Naupaktos further south. The extent of the new province is unclear, but probably matched the extent of the Metropolis of Naupaktos, established at about the same time, encompassing the sees of Vonditsa, Aetos, Acheloos, Rogoi, Ioannina, Hadrianopolis, Photike, and Buthrotum. Vagenetia notably no longer appears as a bishopric. As the authors of the Tabula Imperii Byzantini comment, it appears that "the Byzantine administration had brought the strongly Slavic-settled areas in the mainland somewhat under its control, and a certain Re-Hellenization had set in".[44] Further north, the region around Dyrrhachium existed as the homonymous theme possibly as early as the 9th century.[45]

During the early 10th century, the themes of Cephallenia and Nicopolis appear mostly as bases for expeditions against southern Italy and Sicily, while Mardaites from both themes are listed in the large but unsuccessful expedition of 949 against the Emirate of Crete.[46] In c. 930, the Theme of Nicopolis was raided by the Bulgarians, who even occupied some parts until driven out or subjugated by the Byzantines years later.[46] Only the extreme north of Epirus seems to have remained consistently under Bulgarian rule in the period, but under Tsar Samuel, who moved the centre of Bulgarian power south and west to Ohrid, probably all of Epirus down to the Ambracian Gulf came under Bulgarian rule.[47] This is evidenced from the fact that the territories that were under Bulgarian rule formed part of the autocephalous Archbishopric of Ohrid after the Byzantine conquest of Bulgaria by Emperor Basil II in 1018: thus in Epirus the sees of Chimara, Hadrianopolis, Bela, Buthrotum, Ioannina, Kozyle, and Rogoi passed under the jurisdiction of Ohrid, while the Metropolitan of Naupaktos retained only the sees of Bonditza, Aetos, and Acheloos.[47] Basil II also established new, smaller themes in the region: Koloneia, and Dryinopolis (Hadrianopolis).[47]

The region joined the uprising of Petar Delyan in 1040, and suffered in the First Norman invasion of the Balkans: Dyrrhachium was occupied by the Normans in 1081–1084, Arta was unsuccessfully besieged, and Ioannina was captured by Robert Guiscard.[48] An Aromanian presence in Epirus is first mentioned in the late 11th century, while Jewish communities are attested throughout the medieval period in Arta and Ioannina.[49]

Expansion of the Despotate of Epirus in the early 13th century.

When Constantinople fell to the Fourth Crusade in 1204, the partitio Romaniae assigned Epirus to Venice, but the Venetians were largely unable to effectively establish their authority, except over Dyrrhachium (the "Duchy of Durazzo"). The Greek noble Michael Komnenos Doukas, who had married the daughter of a local magnate, took advantage of this, and within a few years consolidated his control over most of Epirus, first as a Venetian vassal and eventually as an independent ruler. By the time of his death in 1214/5, Michael had established a strong state, the Despotate of Epirus, with the former theme of Nicopolis at its core and Arta as its capital.[50][51] Epirus, and the city of Ioannina in particular, became a haven for Greek refugees from the Latin Empire of Constantinople for the next half-century.[51]

The Despotate of Epirus ruled over Epirus and western Greece as far south as Naupaktos and the Gulf of Corinth, much of Albania (including Dyrrhachium), Thessaly, and the western portion of Macedonia, extending its rule briefly over central Macedonia and most of Thrace following the aggressive expansionism of Theodore Komnenos Doukas, who established the Empire of Thessalonica in 1224.[52][53] During this time, the definition of Epirus came to encompass the entire coastal region from the Ambracian Gulf to Dyrrhachium, and the hinterland to the west up to the highest peaks of the Pindus mountain range. Some of the most important cities in Epirus, such as Gjirokastër (Argyrokastron), were founded during this period.[54] The oldest reference to Albanians in Epirus is from a Venetian document dating to 1210, which states that "the continent facing the island of Corfu is inhabited by Albanians". Kosta Giakoumis believes that the use of hypothetical immigrations to explain the accounts of Albanian presence in Epirote territory prior to the 13th-14th century is somewhat arbitrary.[55]

In 1337, Epirus was once again brought under the rule of the restored Byzantine Empire.[53] In 1348, taking advantage of the civil war between the Byzantine emperors John V Palaiologos and John VI Kantakouzenos, the Serbian king Stefan Uroš IV Dušan conquered Epirus, with a number of Albanian mercenaries assisting him.[56] The Byzantine authorities in Constantinople soon re-established a measure of control by making the Despotate of Epirus a vassal state, but Albanian clans proceeded to invade and seize most of the region. Under Pjetër Losha, the Albanian Malakasi and Mazaraki tribes defeated Nikephoros II Orsini at the Battle of Achelous in 1359, which won Pjetër Losha the rule of Arta; Losha then founded the Despotate of Arta (1358-1416) with the help of the Mazaraki and Malakasi clans.[57]

Although Albanian clans gained control of most of the region by 1366/7, their continued division into rival clans meant that they could not establish a single central authority.[58] Ioannina became a center of Greek resistance to the Albanian clans. The Greeks of Ioannina offered power to three foreign rulers during this time, beginning with Thomas II Preljubović (1367–1384), whose rule was marked by hostilities in the region, as Ioannina came under constant siege by the Mazaraki and Malakasi clans under Losha. These tribes would besiege Ioannina a second time in 1374–1375.[59][60][61] A truce was signed when Pjetër's son Gjin was betrothed to Thomas's daughter Irina, but she would soon die in the 1375 plague and hostilities would recommence.[62] Preljubović attempted to pacify the Albanians of Epirus; however, under Gjin Bua Shpata, the Albanians defeated him.[63]

The reign of Esau de' Buondelmonti (1385–1411) in Ioannina followed, and with an army that consisted of the Albanian tribes of the Mazaraki and Malakasi, he marched against the Principality of Gjirokastër. He was defeated and captured by Albanian nobleman Gjon Zenebishi, and ransomed for 10,000 gold pieces on the intervention of the Venetian governor of Corfu.[64] At the time the Zenebishi clan controlled the area around Gjirokastër (1386–1411), while only the city of Ioannina remained under Greek control.[65]

Carlo I Tocco (1411–1429) then assumed control of Ioannina, commencing heavy conflicts with Jakob and Muriq Shpata, the Albanian leaders of the Despotate of Arta. The Shpata were originally defeated by Carlo's brother Leonardo II Tocco at Mazoma near ancient Nicopolis, but Carlo's son Torno was in turn defeated by the Albanians.[66][67] After the Tocchi succeeded in capturing Rhiniasa, Leonardo tried to take Rogoi and Carlo attempted to take Arta, but Jakob and Muriq succeeded in defending their capital for the time being. Carlo withdrew to Ioannina, but soon after was able to lure Jakob to an ambush near Vobliana: Jakob was captured and immediately executed (1 October 1416).[66][67] Carlo had effectively ended the rule of the Albanian clans in southernmost Epirus.[68]

Nevertheless, internal dissension eased the Ottoman conquest, which began with the capture of Ioannina in 1430 and continued with Arta in 1449, Angelokastro in 1460, Riniasa Castle and its environs (in what is now Preveza) in 1463,[69] and finally Vonitsa in 1479. With the exception of several coastal Venetian possessions, this was also the end of Latin rule in mainland Greece.

Epirus was ruled by the Ottomans for almost 500 years. Ottoman rule in Epirus proved particularly damaging; the region was subjected to deforestation and excessive cultivation, which damaged the soil and drove many Epirotes to emigrate so as to escape the region's pervasive poverty.[1] Nonetheless, the Ottomans did not enjoy total control of Epirus. The Himara and Zagori regions managed to successfully resist Ottoman rule and maintained a degree of independence throughout this period. The Ottomans expelled the Venetians from almost the whole area in the late 15th century.

Between the 16th and 19th centuries, the city of Ioannina attained great prosperity and became a major center of the modern Greek Enlightenment.[70][71][72][73] Numerous schools were founded, such as the Balaneios, Maroutsaia, Kaplaneios, and Zosimaia, teaching subjects such as literature, philosophy, mathematics and physical sciences. In the 18th century, as the power of the Ottoman Empire declined, Epirus became a de facto independent region under the despotic rule of Ali Pasha of Tepelena, a Muslim Albanian brigand who rose to become the provincial governor of Ioannina in 1788.[1] At the height of his power, he controlled all of Epirus, and much of the Peloponnese, central Greece, and parts of western Macedonia[1] Ali Pasha's campaign to subjugate the confederation of the settlements of Souli met with fierce resistance by the Souliot warriors of the mountainous area. After numerous failed attempts to defeat the Souliotes, his troops succeeded in conquering the area in 1803. On the other hand, Ali, who used Greek as official language, witnessed an increase of Greek cultural activity with the establishment of several educational institutions.[74]

When the Greek War of Independence broke out, the inhabitants of Epirus contributed greatly. Two of the founding members of the Filiki Eteria (the secret society of the Greek revolutionaries), Nikolaos Skoufas and Athanasios Tsakalov, came from the Arta area and the city of Ioannina, respectively. Greece's first constitutional prime minister (1844–1847), Ioannis Kolettis, was a native of the village of Syrrako in Epirus and was a former personal physician to Ali Pasha. Ali Pasha tried to use the war as an opportunity to make himself a fully independent ruler, but was assassinated by Ottoman agents in 1822. When Greece became independent in 1830, however, Epirus remained under Ottoman rule. In 1854, during the Crimean War, a major local rebellion broke out. Although the newly found Greek state tried tacitly to support it, the rebellion was suppressed by Ottoman forces after a few months.[75] Another failed rebellion by local Greeks broke out in 1878. During this period, the Ecumenical Patriarchate of Constantinople managed to shut down the few Albanian schools, considering teaching in Albanian a factor that would diminish its influence and lead to the creation of separate Albanian church, while publications in Albanian were banned by the Ottoman Empire.[76][77] In the late 19th century, the Kingdom of Italy opened various schools in the regions of Ioannina and Preveza in order to influence the local population. These schools began to attract students from the Greek language schools, but were ultimately closed after intervention and harassment by the Ecumenical Patriarchate of Constantinople.[78] Throughout, the late period of Ottoman rule (from the 18th century) Greek and Aromanian population of the region suffered from Albanians raiders, that sporadically continued after Ali Pasha's death, until 1912–1913.[79]

While the Treaty of Berlin (1878) awarded large parts of Epirus to Greece, opposition by the Ottomans and the League of Prizren resulted in only the region of Arta being ceded to Greece in 1881.[80] It was only following the First Balkan War of 1912–1913 and the Treaty of London that the rest of southern Epirus, including Ioannina, was incorporated into Greece.[81] Greece had also seized northern Epirus during the Balkan Wars, but the Treaty of Bucharest, which concluded the Second Balkan War, assigned Northern Epirus to Albania.[82]

This outcome was unpopular among local Greeks, as a substantial Greek population existed on the Albanian side of the border.[83] Among Greeks, northern Epirus was henceforth regarded as terra irredenta.[84] Local Greeks in northern Epirus revolted, declared their independence and proclaimed the Autonomous Republic of Northern Epirus in February 1914.[85] After fierce guerrilla fighting, they managed to gain full autonomy under the terms of the Protocol of Corfu, signed by Albanian and Northern Epirote representatives and approved by the Great Powers. The signing of the Protocol ensured that the region would have its own administration, recognized the rights of the local Greeks and provided self-government under nominal Albanian sovereignty.[86] The Republic, however, was short-lived, as when World War I broke out, Albania collapsed, and northern Epirus was alternately controlled by Greece, Italy and France at various intervals.[84][87]

Red dotted line: Territory of Autonomous State of Northern Epirus

Although the Paris Peace Conference of 1919 awarded Northern Epirus to Greece, developments such as the Greek defeat in the Greco-Turkish War and, crucially, Italian lobbying in favor of Albania meant that Greece would not keep Northern Epirus. In 1924, the area was again ceded to Albania.[89]

In 1939, Italy occupied Albania, and in 1940 invaded Greece. The Italians were driven back into Albania, however, and Greek forces again took control of northern Epirus. The conflict marked the first tactical victory of the Allies in World War II. Benito Mussolini himself supervised the massive counter-attack of his divisions in spring 1941, only to be decisively defeated again by the poorly equipped, but determined, Greeks. Nazi Germany then intervened in April 1941 to avert an embarrassing, wholesale Italian defeat. The German military performed rapid military maneuvers through Yugoslavia and forced the encircled Greek forces of the Epirus front to surrender.

The whole of Epirus was then placed under Italian occupation until 1943, when the Germans took over following the Italian surrender to the Allies. Due to the extensive activity of the anti-Nazi Greek resistance (mainly under EDES), the Germans carried out large scaled anti-partisan sweeps, making wide use of Nazi-collaborationist bands of Cham Albanians, who committed numerous atrocities against the civilian population.[90] They fought fiercely against the Greek partisans of the EDES, the latter being ordered by the Allied command to push them out of Greece into Albania. The violent clashes and the reprisals that followed by the Greek guerillas resulted in the expulsion to Albania of almost the entire Cham population.[90]

With the liberation of Greece and the start of the first round of the Greek Civil War at the end of 1944, the highlands of Epirus became a major theater of guerrilla warfare between the leftist Greek People's Liberation Army (ELAS) and the right-wing National Republican Greek League (EDES). In subsequent years (1945–1949), the mountains of Epirus also became the scene of some of the fiercest fighting of the second and bloodier round of the Greek Civil War. The final episode of the war took place on Mount Grammos in 1949, ending with the defeat of the Communists. Peace returned to the region in 1949, although because of official Albanian active involvement in the civil war on the side of the communists, the formal state of war between Greece and Albania remained in effect until 1987. Another reason for the continuation of the state of war until 1987 was that during the entire period of Communist rule in Albania, the Greek population of Northern Epirus experienced forced Albanisation.[91] Although a Greek minority was recognized by the Hoxha regime, this recognition only applied to an "official minority zone" consisting of 99 villages, leaving out important areas of Greek settlement, such as Himara.[84] People outside the official minority zone received no education in the Greek language, which was prohibited in public.[84] The Hoxha regime also diluted the ethnic demographics of the region by relocating Greeks living there and settling in their stead Albanians from other parts of the country.[84] Relations began to improve in the 1980s with Greece's abandonment of any territorial claims over Northern Epirus and the lifting of the official state of war between the two countries.[84]
