Christian emigration in the context of "Greek refugees"

The Greek Orthodox Patriarchate of Antioch (Greek: Ελληνορθόδοξο Πατριαρχείο Αντιοχείας), also known as the Antiochian Orthodox Church and legally as the Rūm Orthodox Patriarchate of Antioch and All the East (Arabic: بطريركيّة أنطاكية وسائر المشرق للروم الأرثوذكس, romanized: Baṭriyarkiyyat ʾAnṭākiya wa-Sāʾir al-Mašriq li-r-Rūm al-ʾUrṯūḏuks, lit. 'Patriarchate of Antioch and All the East for the Orthodox Rum'), is an autocephalous Greek Orthodox church within the wider communion of Eastern Orthodox Christianity that originates from the historical Church of Antioch. Headed by the Greek Orthodox patriarch of Antioch, it considers itself the successor to the Christian community founded in Antioch by the Apostles Peter and Paul. It is one of the largest Christian denominations of the Middle East, alongside the Copts of Egypt and the Maronites of Lebanon.

Its adherents, known as Antiochian Christians, are a Middle-Eastern semi-ethnoreligious Eastern Christian group residing in the Levant region, including the Hatay Province of Turkey. Many of their descendants now live in the global Eastern Christian diaspora. The number of Antiochian Greek Christians is estimated to be approximately 4.3 million.

Christianity in Turkey has a long history, dating back to the early origins of Christianity in Asia Minor and the Middle East during the 1st century AD. In modern times the percentage of Christians in Turkey has declined from 20 to 25% in 1914, to about 2% in 1927, to 0.2–0.4% today. Sources estimate that the Christian population in Turkey ranges between 203,500 and more than 370,000. However, the exact number remains unclear due to the absence of a religious census in the country. The percentage of Christians in Turkey fell mainly as a result of the late Ottoman genocides: the Armenian genocide, Greek genocide, and Assyrian genocide, the population exchange between Greece and Turkey, the emigration of Christians that began in the late 19th century and gained pace in the first quarter of the 20th century, and due to events such as the 1942 Varlık Vergisi tax levied on non-Muslim citizens in Turkey and the 1955 Istanbul pogrom against Greek and Armenian Christians. Exact numbers are difficult to estimate, as many Turkish former Muslim converts to Christianity often hide their Christian faith for fear of familial pressure, religious discrimination, and persecution.

This was due to events which had a significant impact on the country's demographic structure, such as the First World War, the anti-Christian genocides of Greeks, Armenians, and Assyrians perpetrated by Turkish Muslims, and the population exchange between Greece and Turkey, and the emigration of persecuted Christians (such as Assyrians, Greeks, Armenians, etc.) to foreign countries (mostly in Europe and the Americas) that began in the late 19th century and gained pace in the first quarter of the 20th century, especially during World War I. Signed after the First World War, the Treaty of Lausanne explicitly guarantees the security and protection of both Greek and Armenian Orthodox Christian minorities. Their religious institutions are recognized officially by the Republic of Turkey.

Lebanese diaspora refers to Lebanese migrants and their descendants who emigrated from Lebanon and now reside in other countries. There are more people of Lebanese origin (15,4 million) living outside Lebanon than within the country (6 million citizens). The Lebanese diaspora consists of Christians, Muslims, Druze, and Jews. The Christians trace their origin to several waves of emigration, starting with the exodus that followed the 1860 Lebanon conflict during the Ottoman Empire.

Under the current Lebanese nationality law, the Lebanese diaspora do not have an automatic right to return to Lebanon. Varying degrees of assimilation and a high degree of inter-ethnic marriages in the Lebanese diaspora communities, regardless of religious affiliation, have caused many of the Lebanese diaspora not to have passed fluency in Arabic to their children, although most still maintain a Lebanese national identity. Several factors have caused Lebanese emigration, including civil wars, attacks on Lebanese sovereignty and land by Israel and Syria, and political and economic crises.
