How the emergence of communist started a bipolar world?

The emergence of communism, particularly with the 1917 Bolshevik Revolution in Russia, marked the beginning of a significant ideological divide in global politics. This shift led to the establishment of the Soviet Union as a superpower advocating for communist ideals, contrasting sharply with the capitalist democracies, most notably the United States. The subsequent Cold War intensified this divide, creating a bipolar world where nations aligned themselves either with the capitalist bloc led by the U.S. or the communist bloc led by the USSR, shaping international relations and conflicts for decades. Ultimately, this ideological confrontation influenced global politics, economics, and military strategies throughout the 20th century.
