The Azerbaijan Democratic Party was a pro-Soviet, separatist, and pan-Turkist party founded by Jafar Pishevari in Tabriz, Iran, in September 1945. It depended on the Soviet Union and was supported by it. The ADP was founded as an opposition party against the Pahlavi dynasty. The Soviet-supported Tudeh Party dissolved its Azerbaijan chapter and ordered its members to join the ADP. The ADP ruled the Soviet-backed Azerbaijan People's Government from 1945 until 1946 with Pishevari as premier.
