The Church of the East spread widely through Asia, establishing churches and dioceses in India (the Saint Thomas Christians), Central Asia, and China, home to a Nestorian community from the 7th–10th centuries and again in the 13th–14th centuries. Subsequently, however, a series of misfortunes sent the church into decline, and by the 14th century it was largely confined to Mesopotamia/Iraq, south eastern Anatolia/Turkey, north western Persia/Iran and north eastern Syria and the Malabar Coast of India. It remains centered in these areas to this day. In the 16th century, the church went into schism, resulting in the formation of two churches with rival patriarchs: the Assyrian Church of the East and the Chaldean Catholic Church, which eventually entered into communion with Rome.
