Cold War origins refer to the geopolitical tensions and ideological conflicts that developed primarily between the United States and the Soviet Union following World War II, leading to a period of political hostility and military rivalry from 1947 to 1991. The roots of this conflict can be traced back to differing political ideologies, the division of Europe after the war, and the competition for global influence, all significantly influenced by events such as the Potsdam Conference and the division of Germany.
