Jafar Sultan revolt

The Jafar Sultan revolt refers to a Kurdish tribal revolt in Pahlavi Iran, which erupted in 1931, as one of the early tribal-nationalist Kurdish revolts against central Iranian revolt during the early stage of Kurdish separatism in Iran.

Background
Jafar Sultan of Hewraman region took control of the region between Marivan and north of Halabja and remained independent until 1925. Between 1927 and 1934 a number of Kurdish tribal uprisings erupted in the Hewraman and Meriwan regions. In 1926, the Iranian forces fighting insurgents in the Pizhdar, Hewraman and Meriwan areas executed all prisoners as an unprecedented act of brutality, likely among the factors causing thirty one Kurdish chieftains in the region to ask for British protection.

Revolt
Despite the attempts to subdue him under the central rule, the tribal leader revolted in 1929, but was effectively crushed.
