In 1964, Nikita Khrushchev was removed from his position of power and replaced with Leonid Brezhnev. Under his rule, the Russian SFSR and the rest of the Soviet Union went through an era of stagnation. Even after he died in 1982, the era didn’t end until Mikhail Gorbachev took power and introduced liberal reforms in Soviet society.

Leonid Brezhnev
