During the chaos of the Russian Revolutions of 1917, Tatarstan became functionally independent with a national parliament (Millät Mäclese), national government (Milli İdarä), national council (Milli Şura), and a national military council (Xärbi Şura). Some Tatar military units took part in the Russian Civil War against the communists. Anti-communist Tatar revolutionaries declared the Idel-Ural State, but the Moscow Bolshevist government moved to prevent an independent Tatarstan on its flank. The "Muslim Council" was overthrown by a "Workers' Bolshevik Council" in a mostly Tatar-populated part of Kazan province called "Bolaq artı" or "Zabulachye" (In English, the "Transbolaqia Republic"). The Muslim Council was arrested.
