The Cold War, was a period of geopolitical tension between the Soviet Union and the United States, along with their respective allies. Rooted in ideological differences between communism and capitalism, it was marked by a series of political, military, and economic confrontations.

Despite the absence of direct large-scale fighting between the two superpowers, the Cold War saw numerous proxy wars, espionage activities, and a relentless arms race, particularly in nuclear weapons. The conflict profoundly shaped global alliances, international policies, and the socio-political landscape of the 20th century.
