The Greek genocide (Greek: Γενοκτονία των Ελλήνων, romanized: Genoktonía ton Ellínon), which included the Pontic genocide, was the systematic killing of the indigenous Christian Ottoman Greek population of Anatolia because of their religion and ethnicity, which was carried out between 1912 and 1923. This period extended across the Balkan Wars (1912–1913), World War I and its aftermath (1914–1919), and the Turkish War of Independence (1919–1923). The genocide was perpetrated by the government of the Ottoman Empire led by the Three Pashas and by the Government of the Grand National Assembly led by Mustafa Kemal Atatürk.
The genocide included massacres, forced deportations involving death marches through the Syrian Desert, expulsions, summary executions, and the destruction of Eastern Orthodox cultural, historical, and religious monuments. Several hundred thousand Ottoman Greeks died during this period. Most of the refugees and survivors fled to Greece (adding over a quarter to the prior population of Greece). Some, especially those in Eastern provinces, took refuge in the neighbouring Russian Empire. Some who remained organized the resistance to the genocide.
By late 1922, most of the Greeks of Asia Minor had either fled or had been killed. Those remaining were transferred to Greece under the terms of the later 1923 population exchange between Greece and Turkey, which formalized the exodus and barred the return of the refugees. Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including Assyrians and Armenians, and some scholars and organizations have recognized these events as part of the same genocidal policy.
The Allies of World War I condemned the Ottoman government–sponsored massacres. In 2007, the International Association of Genocide Scholars passed a resolution recognising the Ottoman campaign against its Christian minorities, including the Greeks, as genocide. Some other organisations have also passed resolutions recognising the Ottoman campaign against these Christian minorities as genocide, as have the national legislatures of Armenia, Austria, Cyprus, the Czech Republic, Germany, Greece, the Netherlands, Sweden, and the United States.
At the outbreak of World War I, Asia Minor was ethnically diverse; its population included Turks and Azeris, as well as groups that had inhabited the region prior to the Ottoman conquest, including Pontic Greeks, Caucasus Greeks, Cappadocian Greeks, Armenians, Kurds, Zazas, Georgians, Circassians, Assyrians, Jews, and Laz people.
Among the causes of the Turkish campaign against the Greek-speaking Christian population was a fear that they would welcome liberation by the Ottoman Empire's enemies, and a belief among some Turks that to form a modern country in the era of nationalism it was necessary to purge from their territories all minorities who could threaten the integrity of an ethnically based Turkish nation.
According to a German military attaché, the Ottoman minister of war Ismail Enver had declared in October 1915 that he wanted to "solve the Greek problem during the war … in the same way he believe[d] he solved the Armenian problem", referring to the Armenian genocide. Germany and the Ottoman Empire were allies immediately before, and during World War I. By 31 January 1917, the Chancellor of Germany Theobald von Bethmann Hollweg, reported that:
The indications are that the Turks plan to eliminate the Greek element as enemies of the state, as they did earlier with the Armenians. The strategy implemented by the Turks is of displacing people to the interior without taking measures for their survival by exposing them to death, hunger, and illness. The abandoned homes are then looted and burnt or destroyed. Whatever was done to the Armenians is being repeated with the Greeks.
The Greek presence in Asia Minor dates at least from the Late Bronze Age (1450 BC). The Greek poet Homer lived in the region around 800 BC. The geographer Strabo referred to Smyrna as the first Greek city in Asia Minor, and numerous ancient Greek figures were natives of Anatolia, including the mathematician Thales of Miletus (7th century BC), the pre-Socratic philosopher Heraclitus of Ephesus (6th century BC), and the founder of Cynicism Diogenes of Sinope (4th century BC). Greeks referred to the Black Sea as the "Euxinos Pontos" or "hospitable sea" and starting in the eighth century BC they began navigating its shores and settling along its Anatolian coast. The most notable Greek cities of the Black Sea were Trebizond, Sampsounta, Sinope and Heraclea Pontica.
During the Hellenistic period (334 BC – 1st century BC), which followed the conquests of Alexander the Great, Greek culture and language began to dominate even the interior of Asia Minor. The Hellenization of the region accelerated under Roman and early Byzantine rule, and by the early centuries AD the local Indo-European Anatolian languages had become extinct, being replaced by the Koine Greek language. From this point until the late Middle Ages, the majority of Asia Minor practiced Christianity (called Greek Orthodox Christianity after the East–West Schism with the Catholics in 1054) and spoke Medieval Greek as their first language.
The resultant Greek culture in Asia Minor flourished during a millennium of rule (4th–15th century AD) under the mainly Greek-speaking Eastern Roman Empire. Those from Asia Minor constituted the bulk of the empire's Greek-speaking Orthodox Christians; thus, many renowned Greek figures during late antiquity, the Middle Ages, and the Renaissance came from Asia Minor, including Saint Nicholas (270–343 AD), rhetorician John Chrysostomos (349–407 AD), the architect of Hagia Sophia, Isidore of Miletus (6th century AD), several imperial dynasties, including the Phokas (10th century) and Komnenos (11th century), and Renaissance scholars George of Trebizond (1395–1472) and Basilios Bessarion (1403–1472).
Thus, when the Turkic peoples began their late medieval conquest of Asia Minor, Byzantine Greek citizens were the largest group of inhabitants there. Even after the Turkic conquests of the interior, the mountainous Black Sea coast of Asia Minor remained the heart of a populous Greek Christian state, the Empire of Trebizond, until its eventual conquest by the Ottoman Turks in 1461, a year after the Ottomans conquered the area of Europe which is now the Greek mainland. Over the next four centuries the Greek natives of Asia Minor gradually became a minority in these lands under the now dominant Turkic culture.
Beginning in the spring of 1913, the Ottomans implemented a programme of expulsions and forcible migrations, focusing on Greeks of the Aegean region and eastern Thrace, whose presence in these areas was deemed a threat to national security. The Ottoman government adopted a "dual-track mechanism", whereby official government acts were accompanied by unofficial covert, extralegal, but state-sponsored acts of terror under the protective umbrella of state policies, thereby allowing the Ottoman government to deny responsibility for and prior knowledge of this campaign of intimidation, emptying Christian villages. The involvement in certain cases of local military and civil functionaries in planning and executing anti-Greek violence and looting led ambassadors of Greece and the Great Powers and the Patriarchate to address complaints to the Sublime Porte. In protest to government inaction in the face of these attacks and to the so-called "Muslim boycott" of Greek products that had begun in 1913, the Patriarchate closed Greek churches and schools in June 1914. Responding to international and domestic pressure, Talat Pasha headed a visit in Thrace in April 1914 and later in the Aegean to investigate reports and try to soothe bilateral tension with Greece. While claiming that he had no involvement or knowledge of these events, Talat met with Kuşçubaşı Eşref, head of the "cleansing" operation in the Aegean littoral, during his tour and advised him to be cautious not to be "visible". Also, after 1913 there were organized boycotts against the Greeks, initiated by the Ottoman Interior Ministry who asked the empire's provinces to start them. The British ambassador in Constantinople at that time described the boycott as a direct result of the Committee of Union and Progress and that "Committee emissaries are everywhere instigating the people", adding that every person, Greek or Muslim, who entered a non-Muslim shop was beaten.
