Manichaeism didn't collapse with the rise of Islam and in the 8th century became the state religion of the Uygurs in Central Asia. In many ways, the story of Manichaeism parallels that of the Christian Church of the East or Nestorianism. Both originally gained protection from the Sassanids. However, the Sassanids became more and more Zorostrain and so both religions started moving into Central Asia. While outside the Uygurs, Manichaeism did not get a major following, it was still present in the area until around the 13th to 14th century, when a combination of Mongolian/ Timirid devastation and assertion of Islam as the one religion in the area made both Nestorianism and Manichaeism extinct in the region.
