History of the Republic of Turkey in the context of "Atatürk"

Minorities in Turkey form a substantial part of the country's population, representing an estimated 25 to 28 percent of the population. Historically, in the Ottoman Empire, Islam was the official and dominant religion, with Muslims having more rights than non-Muslims, whose rights were restricted. Non-Muslim (dhimmi) ethno-religious groups were legally identified by different millet ("nations").

Following the end of World War I and the dissolution of the Ottoman Empire, all Ottoman Muslims were made part of the modern citizenry or the Turkish nation as the newly founded Republic of Turkey was constituted as a Muslim nation state. While Turkish nationalist policy viewed all Muslims in Turkey as Turks without exception, non-Muslim minority groups, such as Jews and Christians, were designated as "foreign nations" (dhimmi). Conversely, Turk (term for Muslims) was used to denote all groups in the region who had been Islamized under Ottoman rule, especially Muslim Albanians and Slavic Muslims.

The history of Anatolia (often referred to in historical sources as Asia Minor) can be roughly subdivided into: Prehistory of Anatolia (up to the end of the 3rd millennium BCE), Ancient Anatolia (including Hattian, Hittite and post-Hittite periods), Classical Anatolia (including Achaemenid, Hellenistic and Roman periods), Byzantine Anatolia (later overlapping, since the 11th century, with the gradual Seljuk and Ottoman conquest), Ottoman Anatolia (14th–20th centuries) and the Modern Anatolia, since the creation of the Republic of Turkey.

The 1980 Turkish coup d'état (Turkish: 12 Eylül darbesi, lit. 'September 12 coup d'état'), headed by Chief of the General Staff General Kenan Evren, was the third coup d'état in the history of the Republic of Turkey, the previous having been the 1960 coup and the 1971 coup by memorandum.

During the Cold War era, Turkey saw political violence (1976–1980) between the far-left, the far-right (Grey Wolves), the Islamist militant groups, and the state. The violence saw a sharp downturn for a period after the coup, which was welcomed by some for restoring order by quickly executing 50 people and arresting 500,000, of which hundreds would die in prison.

Mustafa Kemal Atatürk (c. 1881 – 10 November 1938) was a Turkish field marshal and statesman who was the founder of the Republic of Turkey, serving as its first president from 1923 until his death in 1938. He undertook sweeping reforms, which modernized Turkey into a secular, industrializing nation. Ideologically a secularist and nationalist, his policies and socio-political theories became known as Kemalism.

Born in Salonica in the Ottoman Empire, his early military career saw him involved in the Italo-Turkish and Balkan Wars. As a member of the Committee of Union and Progress and the Young Turks, he played an important part in political events of the late Ottoman Empire, such as the Young Turk Revolution and the 31 March Incident. He rose to prominence with his role in the Defence of Gallipoli during World War I. Following the defeat of the empire after the war, he led the Turkish National Movement, which resisted the empire's partition among the victorious Allied powers. Establishing the provisional "Ankara government", he defeated the forces sent by the Allies, thus emerging victorious from the Turkish War of Independence. During and after the war, the ethnic cleansing of Armenians and Greeks from Anatolia outside of Istanbul, including the Kars region invaded by the Kemalist armies, was largely completed via large-scale massacres, flight, expulsions, and the population exchange between Greece and Turkey. His government subsequently proceeded to abolish the Ottoman sultanate in 1922 and proclaimed the Republic of Turkey in its place in 1923.

The persecution of Christians can be traced from the first century of the Christian era to the present day. Christian missionaries and converts to Christianity have both been targeted for persecution, sometimes to the point of being martyred for their faith, ever since the emergence of Christianity.

Early Christians were persecuted at the hands of both Jews, from whose religion Christianity arose, and the Romans who controlled many of the early centers of Christianity in the Roman Empire. Since the emergence of Christian states in Late Antiquity, Christians have also been persecuted by other Christians due to differences in doctrine which have been declared heretical. Early in the fourth century, the empire's official persecutions were ended by the Edict of Serdica in 311 and the practice of Christianity legalized by the Edict of Milan in 312. By the year 380, Christians had begun to persecute each other. The schisms of late antiquity and the Middle Ages – including the Rome–Constantinople schisms and the many Christological controversies – together with the later Protestant Reformation provoked severe conflicts between Christian denominations. During these conflicts, members of the various denominations frequently persecuted each other and engaged in sectarian violence.

The history of Turkey, understood as the history of the area now forming the territory of the Republic of Turkey, includes the history of both Anatolia (the Asian part of Turkey) and Eastern Thrace (the European part of Turkey). These two previously politically distinct regions came under control of the Roman Empire in the second century BC, eventually becoming the core of the Roman Byzantine Empire. For times predating the Ottoman period, a distinction should also be made between the history of the Turkic peoples, and the history of the territories now forming the Republic of Turkey From the time when parts of what is now Turkey were conquered by the Seljuq dynasty, the history of Turkey spans the medieval history of the Seljuk Empire, the medieval to modern history of the Ottoman Empire, and the history of the Republic of Turkey since the 1920s.
