September Uprising
The September Uprising (, "Septemvriysko vastanie") was an armed insurgency staged in September 1923 by the Bulgarian Communist Party (BCP) under Comintern pressure and attempted to overthrow Alexander Tsankov's new government of Bulgaria that had come to power with the coup d'état of 9 June. Besides its communist base, the uprising was also supported by agrarians and anarchists. The uprising's goal was the "establishment of a government of workers and peasants" in Bulgaria.
