Three Pashas in the context of Djemal Pasha

The Greek genocide (Greek: Γενοκτονία των Ελλήνων, romanized: Genoktonía ton Ellínon), which included the Pontic genocide, was the systematic killing of the Christian Ottoman Greek population of Anatolia, which was carried out mainly during World War I and its aftermath (1914–1922) – including the Turkish War of Independence (1919–1923) – on the basis of their religion and ethnicity. It 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, against the indigenous Greek population of the Empire. 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.

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 Pontic Greek genocide, or the Pontic genocide (Greek: Γενοκτονία των Ελλήνων του Πόντου), was the deliberate and systematic destruction of the indigenous Greek community in the Pontus region (the northeast of modern Turkey) in the Ottoman Empire during World War I and its aftermath.

The Pontic Greeks had a continuous presence in the Pontus region from at least 700 BC, over 2,500 years ago. Following the Ottoman conquest of the Empire of Trebizond in 1461, the area came under the control of the Ottoman Empire. The rise of Turkish nationalism at the beginning of 20th century dramatically increased anti-Greek sentiment within the Ottoman Empire. The genocide began in 1914 by the Young Turk regime, which was led by the Three Pashas, and, after a short interwar pause in 1918–1919, continued into 1923 by the Kemalist regime which was led by Mustafa Kemal Pasha. Both nationalist movements massacred the Pontians and deported them to the interior regions of Anatolia. This resulted in approximately 350,000 deaths – about half of the pre-genocide Pontic population.

Starting in the 19th century the Ottoman Empire's governing structure slowly transitioned and standardized itself into a Western style system of government, sometimes known as the Imperial Government. Mahmud II (r. 1808–1839) initiated this process following the disbandment and massacre of the Janissary corps, at this point a conservative bureaucratic elite, in the Auspicious Incident. A long period of reform known as the Tanzimat period started, which yielded much needed reform to the government and social contract with the multicultural citizens of the empire.

In the height of the Tanzimat period in 1876, Abdul Hamid II (r. 1876–1909) turned the Empire into a constitutional monarchy by promulgating the Empire's first Constitution, which established the short First Constitutional Era and also featured elections for a parliament. Defeat in the 1877–1878 War with Russia and dissatisfaction with Abdul Hamid lead to the "temporary" suspension of the constitution and the parliament, resulting in a modern despotism/autocracy of Abdul Hamid, during which internal reform continued. The Young Turk Revolution in 1908 started the longer lasting Second Constitutional Era and forced Abdul Hamid to reinstate the constitution, recall the parliament, and hold elections again which this time which featured political parties. However, by 1913 the Ottoman Empire was a dictatorship of the Committee of Union and Progress (CUP), led by the Three Pashas (Talat Pasha, Enver Pasha, and Cemal Pasha). This dictatorship capitalized on the developed bureaucracy created through a century of reform and centralization by undertaking genocide against Christian minorities. The CUP also undertook many reforms relating to social structure, religion, and education, which would be continued and more far reaching under Mustafa Kemal Atatürk's regime. The Union and Progress dictatorship lasted until the end of World War I, which lead to the Empire's collapse and subsequent abolition by Turkish nationalist forces led by Atatürk.

İsmâil Enver (Ottoman Turkish: اسماعیل انور پاشا; Turkish: İsmail Enver Paşa; 23 November 1881 – 4 August 1922), better known as Enver Pasha, was an Ottoman Turkish military officer, revolutionary, and convicted war criminal who was a part of the dictatorial triumvirate known as the "Three Pashas" (along with Talaat Pasha and Cemal Pasha) in the Ottoman Empire.

While stationed in Ottoman Macedonia, Enver joined the Committee of Union and Progress (CUP), an organization affiliated with the Young Turks movement that was agitating against Sultan Abdul Hamid II's despotic rule. He was a key leader of the 1908 Young Turk Revolution, which reestablished the Constitution and parliamentary democracy in the Ottoman Empire. Along with Ahmed Niyazi, Enver was hailed as "hero of the revolution". However, a series of crises in the Empire, including the 31 March Incident, the Balkan Wars, and the power struggle with the Freedom and Accord Party, left Enver and the Unionists disillusioned with liberal Ottomanism. After the 1913 Ottoman coup d'état brought the CUP directly to power, Enver became War Minister, while Talaat assumed control over the civilian government.

Mehmed V Reşâd (Ottoman Turkish: محمد خامس, romanized: Meḥmed-i ḫâmis; Turkish: V. Mehmed or Mehmed Reşad; 2 November 1844 – 3 July 1918) was the penultimate sultan of the Ottoman Empire from 1909 to 1918. Mehmed V reigned as a constitutional monarch. He had little influence over government affairs and the Ottoman constitution was held with little regard by his ministries. The first half of his reign was marked by increasingly polarizing politics, and the second half by war and domination of the Committee of Union and Progress (CUP) and the Three Pashas.

Reşad was the son of Sultan Abdülmecid I. He succeeded his half-brother Abdul Hamid II after the 31 March Incident. Coming to power in the aftermath of the failed coup attempt, his nine-year reign featured three coups d'etat, four wars, eleven governments, and numerous uprisings. The Italo-Turkish War saw the cession of the Empire's North African territories and the Dodecanese Islands, including Rhodes, during which the CUP was forced out of power by the military. This was followed up by the traumatic loss of almost all of the Empire's European territories west of Constantinople (now Istanbul) in the First Balkan War, and the return of a now radicalized CUP rule in another coup. Eastern Thrace was retaken in the Second Balkan War.

Ahmed Djemal Pasha (Ottoman Turkish: احمد جمال پاشا; Turkish: Ahmed Cemâl Paşa; 6 May 1872 – 21 July 1922) was an Ottoman general and statesman. Along with Talaat and Enver, he was one of the Three Pashas that ruled the Ottoman Empire during World War I.

As an officer of the II Corps, he was stationed in Salonica, where he developed political sympathies for the Committee of Union and Progress (CUP), a secret reformist party. He was initially praised by Christian missionaries and provided support to the Armenian victims of the Adana massacres.
