The contest for world leadership that emerged after World War II is known as the Cold War, primarily between the Soviet Union and its communist allies and the United States along with its Western allies. This ideological struggle was characterized by political tension, military competition, and economic rivalry, rather than direct military conflict. The Cold War led to significant events such as the arms race, the space race, and numerous proxy wars around the globe. Ultimately, it shaped international relations and global dynamics for several decades until the dissolution of the Soviet Union in 1991.
