In February 1917 (old style calendar), a revolution took place in the Russian Empire which forced the abdication of the Czar. A provisional government was created until such time as elections could be called. The provisional government had to face a few crisis originating both from the far-left and far-right which threaten to bring it down. What saved it was the so-called "Karensky Offensive". While its strategic impact proved negligible, its impact on morale was far greater, allowing the provisional government to marginalise the Communists (Bolsheviks) and the Monarchists.
