Ask AI: Summarize the story of the Russian monarchy, the Bolsheviks, and the rise communism in 3-5 sentences.

The Russian monarchy, helmed by the Romanov dynasty, ruled for over three centuries until discontent during World War I led to the abdication of Tsar Nicholas II in 1917. The chaos that followed allowed the Bolsheviks, a radical socialist group led by Vladimir Lenin, to seize power later that year in the October Revolution, leading to the overthrow of the provisional government. The Bolsheviks established a communist regime, which eventually evolved into the Soviet Union, marking the rise of communism in Russia and setting the stage for significant political and social transformations that lasted until the USSR's dissolution in 1991.
