The Church of the East and the Nineveh Plains

Mesopotamia is the cradle of the Church of the East, which sent missionaries to India and China and whose scholars translated philosophy and medicine into Arabic. Syriac remains both a liturgical and a living language in the Nineveh Plains, but Iraq's Christian community has shrunk sharply since 2003.

Christian population

About 150,000–250,000 today

Estimates; there were roughly 1.2–1.4 million before 2003.

Languages of liturgy and life

Syriac (Eastern Aramaic) as a liturgical language, with Sureth as an everyday language for many, alongside Arabic and Kurdish.

  • Chaldean Catholic Church

    الكنيسة الكلدانية الكاثوليكية

    The largest denomination; its see is in Baghdad, in communion with Rome.
