Iraq is home to one of the oldest, continuous Christian communities in the world. Christians in Iraq come from numerous ethno-religious backgrounds, including Armenian Catholics and Orthodox, Assyrian Church of the East, Assyrian Orthodox, Chaldean Catholics, Evangelical, Protestant, and Syriac Catholic and Orthodox.
Prior to 2003, Christians (Assyrian/Chaldean/Syriac/Armenian) were one of the largest ethnic minorities in Iraq, estimated to have numbered around 1.5 million.
By June 2014, an estimated two-thirds of the pre-2003 Christian community had fled the country. Regardless of the merits of the 2003 invasion, it directly led to the unleashing of sectarian violence that made Christians an easy target for ethno-religious cleansing. As the Islamic State in Iraq and Syria (ISIS) have swept across Iraq, Christians there have become the victims of genocide. Approximately 400,000 Christians were left in Iraq before ISIS began its genocidal campaign to cleanse them and other religious minorities from the country. Only 200,000 Christians now remain, predominately as IDPs within the borders of the Kurdish Regional Government (KRG).
Experts estimate that if nothing is done to help this community, there will be no Christians left in Iraq within five years.
