Firqah-i Dimukrat, or

Ja'far Pishevari. After the announcement, the communist, Soviet-supported
Tudeh party dissolved its Azerbaijan chapter and ordered its members to join ADP. ADP expanded throughout
Iranian Azerbaijan, and initiated a local coup d'état with help from Soviet army, who prevented the Iranian army from intervening. During the first week of September 1945, the Azerbaijani Democratic Party, led by Ja'far Pishevari, a long-time leader of the revolutionary movement in
