The Knanaya Community traces its origin back to a Jewish-Christian migration from Southern Mesopotamia (present Iraq) to the Malabar Coast of Cranganore (Kodungalloor, Kerala, India) in A.D. 345 under the leadership of an enterprising merchant Thomas of Kinai (Knai Thomman). The migration comprised 400 persons belonging to 72 families from seven clans. Bishop Urha Mar Yousef, four priests, and several deacons were among them as Christian missionaries.
