Church of the East
The church undertook very extensive missionary work, and even had outposts in China from 635 until ‘foreign’ religions were expelled in 845 (see HSI-AN FU). At present, the Nestorians form a very small community in Iraq (the patriarchate was restored to Baghdād in 1976 with the election of Mar Denḥa IV), together with other small populations in the Middle E., N. and S. America, and S. India (this being a dissident body from the Syro-Malabar Church).
