Bektashi Order
Timur (Tamurlane) invaded Azerbaijan during the 1380s, temporarily incorporating it into his Eurasian domain. Shirvan, under Ibrahim I of Shirvan, was also a vassal state of Timur and assisted him in his war with the Mongol ruler Tokhtamysh of the Golden Horde. Azerbaijan experienced social unrest and religious strife during this period due to sectarian conflict initiated by Hurufism, the Bektashi Order, and other movements.
