The Cold War was a prolonged period of geopolitical tension between the Soviet Union and the United States, along with their respective allies, lasting from the end of World War II in 1947 until the dissolution of the Soviet Union in 1991. This era was marked by ideological conflict, military buildup, and proxy wars, deeply influencing global politics, culture, and society, as well as shaping postmodern literature that often reflected the anxieties and complexities of this time.
