The Russian Revolution played a crucial role in global politics by challenging the established order and promoting communism on a worldwide scale. The 1917 revolutions resulted in the collapse of the Tsarist regime and the rise of the Bolsheviks, who aimed to spread their transformative ideology internationally. This shift influenced many countries, inspiring leftist movements and prompting fears of communism during the Cold War. The revolution also highlighted tensions between capitalistic and socialist models, shaping international relations and ideologies throughout the 20th century. Its repercussions are evident in numerous revolutions and political movements globally.
