Christianity in Iraq has its roots from the conception of the Church of the East in the 5th century AD, predating the existence of Islam in the region. Christians in Iraq are predominantly native Assyrians belonging to the Ancient Church of the East, Assyrian Church of the East, Chaldean Catholic Church, Syriac Catholic Church and Syriac Orthodox Church. There is also a significant population of Armenian Christians in Iraq who had fled Turkey during the Armenian genocide. Christians numbered over 1.4 million in 1987 or 8% of the estimated population of 16.3 million and 550,000 in 1947 or 12% of the population of 4.6 millions. After the 2003 invasion of Iraq, violence against Christians rose, with reports of abduction, torture, bombings, and killings. The post-2003 Iraq War have displaced much of the remaining Christian community from their homeland as a result of ethnic and religious persecution at the hands of Islamic extremists.
