The February Revolution had overthrown the Tsarist autocracy, resulting in a provisional government. The provisional government had taken power after being proclaimed by Grand Duke Michael, Tsar Nicholas II's younger brother, who declined to take power after the Tsar stepped down. During this time, urban workers began to organize into councils (soviets) wherein revolutionaries criticized the provisional government and its actions. The provisional government remained widely unpopular, especially because it was continuing to fight in World War I, and had ruled with an IRON fist throughout the summer (including killing hundreds of protesters in the July Days).
