Manicheaism

Manicheaism was a religion founded in the 3rd century based on the teachings of the alleged prophet, Mani. Initally it acknowledged Jesus as God but later as one of many gods, rather than the one true God and may have influenced the development of Islam.

The alleged Prophet Mani

The religion changed a lot over time and was initially much more Christian, before becoming more influenced by Gnosticism, until being much more Buddhist. Today the last Manichean Church is used as a Buddhist temple.
