Messianic movement in 17th-century Kurdistan

Ottoman historian Silahdar Mehmed Agha mentions the emergence of a messianic movement in 17th-century Kurdistan. In the premodern age, Kurdistan was often open to Messianic movements, particularly when empires attempted to rule the region and shape the populace to suit their objectives: 

It was submitted to the Imperial Court [in Constantinople] by the former beylerbeyi of Mosul, Pahlavān 'Alī Pasha son of Hajji Pīr, that a certain shaykh and descendant of the Prophet among the 'ulama' of the Kurds in the province of 'Ammadiya named 'Abdallāh, due to excessive affection, had claimed 'My son Mehmet (Muhammad) is the Mahdī,' and gathered a group of Kurds around him. The more this group increased, the more probable became the possibility that they might cause dissension and disorder. The aforementioned 'Alī Pasha, together with the governor of 'Ammadiya, after having secured a fatwā, marched against them and after a heavy slaughter defeated the aforementioned Kurds. Sayyid 'Abdallah, who was responsible for this society, escaped and was captured by 'Alī Pasha, while his son was apprehended in a cave by the Walī of Diyarbakr, Wazir Shaytan Ibrāhīm Pasha.
