The 1950s (pronounced nineteen-fifties; commonly abbreviated as the fifties (among other variants)) was a decade of the Gregorian calendar that began on January 1, 1950, and ended on December 31, 1959.
By its end, the world had largely recovered from World War II and the Cold War developed from its modest beginning in the late-1940s to a hot competition between the United States and the Soviet Union by the early-1960s.
Clashes between communism and capitalism dominated the decade, especially in the Northern Hemisphere. The conflicts included the Korean War in the beginnings of the decade and the beginning of the Space Race with the launch of Sputnik 1. Along with increased testing of nuclear weapons (such as RDS-37 and Upshot–Knothole), this created a politically conservative climate. In the United States, the Second Red Scare caused Congressional hearings by both houses in Congress and anti-communism was the prevailing sentiment in the United States throughout the decade. The beginning of decolonization in Africa and Asia took place in this decade and accelerated in the following decade.
