How did the Russian Revolution change its government?

The Russian Revolution of 1917 led to the overthrow of the Tsarist autocracy, resulting in the establishment of a provisional government that aimed to create a democratic state. However, this government was short-lived, as the Bolsheviks, led by Vladimir Lenin, seized power in the October Revolution, ultimately leading to the creation of a socialist state. This marked the transition from a monarchy to a communist regime, fundamentally altering the political landscape of Russia and paving the way for the formation of the Soviet Union. The revolution also sparked widespread social and economic changes, reshaping Russian society.
