The Russian Revolution started on March 8, 1917, and lasted till June 16, 1923. It was one of the most explosive political events of the twentieth century. It took place in the then capital Petrograd (now Saint Petersburg). Russia had over one million casualties and no longer had the facilities to fight. The violent revolution marked the end of the Romanov dynasty and centuries of Russian Imperial rule. During the Russian Revolution, the Bolsheviks, led by the revolutionary Vladimir Lenin, seized power and destroyed the tradition of czarist rule. The Bolsheviks would later become the Communist Party of the Soviet Union. The Russian Revolution paved the way for the rise of communism as an influential political belief system around the world. It set the stage for the rise of the Soviet Union as a world power.
