The 1979 Kurdish rebellion in Iran erupted in mid-March 1979, some two months after the completion of the Iranian Revolution. It subsequently became the largest among the nationwide uprisings in Iran against the new state and one of the most intense Kurdish rebellions in modern Iran. Initially, Kurdish movements were trying to align with the new government of Iran, seeking to emphasize their Muslim identity and seek common ground with other Iranians. The KDPI even briefly branded itself as a non-separatist organization, allegedly criticizing those calling for independence, but nevertheless calling for political autonomy. However, relations between some Kurdish organizations and the Iranian government quickly deteriorated, and though Shi'a Kurds and some tribal leaders turned towards the new Shi'a Islamic State, Sunni Kurdish leftists continued the nationalist project in their enclave in Kurdistan Province.
