The abdication of Tsar Nicholas II in light of the February Revolution in Russia in February 1917, activated a rather dormant political life in Belarus. As central authority waned, different political and ethnic groups strived for greater self-determination and even secession from the increasingly ineffective Russian Provisional Government. The momentum picked up after the incompetent actions of the 10th Army during the ill-fated Kerensky offensive during the summer. Representatives of Belarusian regions and of different (mostly left-wing) newly established political powers, including the Belarusian Socialist Assembly, the Christian democratic movement and the General Jewish Labour Bund, formed a Belarusian Central Council.
