Cold War Era

Following World War II, the United States entered a prolonged geopolitical struggle with the Soviet Union known as the Cold War. This period included military conflicts such as the Korean War (1950–1953) and the Vietnam War (1955–1975), alongside the global competition for technological and ideological dominance exemplified by the Space Race. Domestically, the Civil Rights Movement challenged racial segregation and fought for equality, reshaping American society. The Cold War era defined U.S. foreign policy, culture, and politics for nearly half a century, leaving a lasting impact on both domestic and international affairs.
