Ancient Church of the East

The Ancient Church of the East (ACE) is an East Syriac Christian denomination based in Baghdad and is composed largely of ethnic Assyrians. It separated from the Assyrian Church of the East in 1964 to establish an independent ecclesial communion, and is one of the churches that descend from historic Church of the East, alongside the Assyrian Church of the East, the Chaldean Catholic Church, and the Syro-Malabar Catholic Church.
