Christianity in Iraq

The vast majority of Christians in Iraq are indigenous Assyrians who descend from ancient Assyria, and are considered to be one of the oldest continuous Christian communities in the world. They primarily adhere to the Syriac Christian tradition and rites and speak Northeastern Neo-Aramaic dialects, although Turoyo is also present on a smaller scale. Some are also known by the name of their religious denomination as well as their ethnic identity, such as Chaldo-Assyrians, Chaldean Catholics or Syriacs. Non-Assyrian Iraqi Christians include Arab Christians and Armenians, and a very small minority of Kurdish, Shabaks and Iraqi Turkmen Christians. Regardless of religious affiliation (Assyrian Church of the East, Chaldean Catholic Church, Syriac Orthodox Church, Syriac Catholic Church, Assyrian Pentecostal Church, etc.) Assyrians Christians in Iraq and surrounding countries are one genetically homogeneous people and are of different origins than other groups in the country, with a distinct history of their own harking back to ancient Assyria and Mesopotamia.^[1]

Syriac Christianity was first established in Mesopotamia, and certain subsets of that tradition (namely the Church of the East and its successor churches) were established in northern and central-southern Iraq, and would eventually spread to becoming one of the most popular Christian churches in the Middle East and Fertile Crescent Region, and would spread as far as India and China.

Iraq plays a rich and vital contribution to Christian history, and after Israel, Iraq has the most biblical history of any other country in the world.^[2] The patriarch Abraham was from Ur, in southern Iraq, modern day Nasiriya, and Rebecca was from northwestern Iraq, in Assyria. Additionally, Daniel lived in Iraq most of his life. The prophet Ezekiel was from southern Iraq and his shrine is located there. Shrines of the prophet Jonah and Saint George are also located there, and various other biblical prophets and saints are said to have been originally from there as well. Adam and Eve are also widely thought to have hailed from Iraq, as the biblical Garden of Eden is largely attributed to have been located in southern Iraq.^[2]^[3]

Prior to the Gulf War in 1991, Christians numbered one million in Iraq.^[4] This may be an undercount by half as seen in the 1987 census numbers. The Ba’athist rule under Saddam Hussein kept anti-Christian violence under control but subjected some to "relocation programmes".^[4] Under this regime, the predominantly ethnically and linguistically distinct Assyrian people were pressured to identify as Arabs. The Christian population fell to an estimated 800,000 during the 2003 Iraq War.^[4]

During the 2013–2017 Iraq War, with ISIS rapidly sweeping through Iraq's western lands, Christian Assyrians and Armenians fled as they feared persecution by the terrorist organisation, as they were to ‘execute’ any person who did not believe in their Sunni sect. Thousands of Iraqi Christians fled to Baghdad, the nation's capital, where they found refuge and adequate housing, some of whom have chosen to make Baghdad their new permanent home following the full defeat of ISIS in Iraq.^[5] Thousands have also fled to other parts of southern Iraq, such as the Shia-majority city of Najaf which housed thousands of Christians in holy Islamic shrines once they fled from ISIS, which sought to exterminate them.^[6] A large population have also returned to their homes en masse following the defeat of ISIS and were able to celebrate Christian festivals of Christmas and Easter in safety with the protection of the Assyrian Nineveh Plain Protection Units and its allies.^[7]^[8]

The current number of Assyrians of Iraq is said to be less than 140,000 in 2024, according to the non-profit Shlama Foundation.^[9]^[10] Total Christians based on religion is likely only slightly larger.
