paragraph_text: Period of developed socialism or Era of Stagnation
  
  Following the ousting of Khrushchev in 1964, another period of collective rule ensued, until Leonid Brezhnev became the leader. The era of the 1970s and the early 1980s was later designated as the Era of Stagnation. The 1965 Kosygin reform aimed for partial decentralisation of the Soviet economy. In 1979, after a communist-led revolution in Afghanistan, Soviet forces invaded the country, ultimately starting the Soviet–Afghan War. In May 1988, the Soviets started to withdraw from Afghanistan, due to international opposition, persistent anti-Soviet guerrilla warfare, and a lack of support by Soviet citizens.
