Northern Epirus in the context of "Autonomous Republic of Northern Epirus"

The Greeks in Albania are ethnic Greeks who live in or originate from areas within modern Albania. They form the largest minority group in the country. They are mostly concentrated in the south of the country, in the areas of the northern part of the historical region of Epirus, in parts of Vlorë County, Gjirokastër, Korçë, and Berat County. The area is also known by them as Northern Epirus. Consequently, the Greeks hailing specifically from Southern Albania are also known as Northern Epirotes (Greek: Βορειοηπειρώτες Vorioipirotes, Albanian: Vorioepirot). The Greeks who live in the "minority zones" of Albania are officially recognised by the Albanian government as the Greek National Minority of Albania (Greek: Ελληνική Μειονότητα στην Αλβανία, Elliniki Mionotita stin Alvania; Albanian: Minoriteti Grek në Shqipëri).

In 1913, after the end of five centuries of Ottoman rule, the area was included under the sovereignty of the newly founded Albanian state. The following year, Greeks revolted and declared their independence, and with the following Protocol of Corfu the area was recognised as an autonomous region under nominal Albanian sovereignty. However, this was never implemented.

The Protocol of Corfu (Greek: Πρωτόκολλο της Κέρκυρας, Albanian: Protokolli i Korfuzit), signed on 17 May 1914, was an agreement between the representatives of the Albanian Government and the Provisional Government of Northern Epirus, which officially recognized the area of Northern Epirus as an autonomous self-governing region under the sovereignty of the prince of the newly established Principality of Albania. The agreement granted the Greeks of the districts of Korytsa (Korçë) and Argyrokastro (Gjirokastër), which form Northern Epirus, wider religious, educational, cultural and political autonomy, inside the borders of the Albanian state.

After the end of the Balkan Wars (1912–1913), the subsequent peace treaties ceded the region to Albania. This turn of events catalyzed an uprising among the local Greeks, which led to the Northern Epirote Declaration of Independence, on 28 February 1914. The International Commission of Control, an organization responsible for securing peace and stability in the region, eventually intervened and the Protocol of Corfu was signed on 17 May 1914. However the protocol's terms were never fully implemented because of the politically unstable situation in Albania following the outbreak of World War I, and it was eventually annulled in 1921 during the Conference of Ambassadors.

The Northern Epirote Declaration of Independence occurred on February 28, 1914, as a reaction to the incorporation of Northern Epirus into the newly established Principality of Albania. The region of Northern Epirus, which corresponds to modern-day southern Albania, came under the control of the Greek forces during the Balkan Wars of 1912–13. However, the subsequent Protocol of Florence assigned it to the newly established Albanian state, a decision that was rejected by the local Greek population. As the Greek army withdrew to the new border, a Panepirotic Assembly was organized by the representatives of Northern Epirus in Gjirokastër (Greek: Argyrokastro). Given the fact that union of Northern Epirus with Greece had already been dismissed by the European Great Powers, they decided that only autonomy or alternatively an international occupation would be appropriate for the region. Finally, Georgios Christakis-Zografos, the head of the assembly, declared the independence of the Autonomous Republic of Northern Epirus.

Zografos proclaimed that the aspirations of the people of Northern Epirus were overlooked since the Great Powers had dismissed the idea of self-government within the Albanian state. After negotiations between Albanian and Northern Epirote representatives in early May, and with the mediation of the Great Powers, the Protocol of Corfu was signed. The agreement recognized Northern Epirus as an autonomous and self-governing region of Albania under the suzerainty of the Albanian prince, while also acknowledging the Greek character of the area. However, due to political instability in Albania at that time, the protocol was never put into effect.

At the outbreak of World War I in August 1914, the Kingdom of Greece remained neutral. Nonetheless, in October 1914, Greek forces once more occupied Northern Epirus, from where they had retreated after the end of the Balkan Wars. The disagreement between King Constantine, who favoured neutrality, and the pro-Allied Prime Minister Eleftherios Venizelos led to the National Schism, the division of the state between two rival governments. Finally, Greece united and joined the Allies in the summer of 1917.
