The main consequence of the Russian Revolution for the rest of the world was the emergence of communism as a powerful global ideology. The success of the Bolshevik Party in 1917 led to the establishment of the Soviet Union, inspiring leftist movements worldwide. This shift intensified ideological conflicts during the Cold War, influencing political dynamics, aligning nations into blocs, and shaping global politics for much of the 20th century, as well as impacting social and economic systems globally.
