What happened
Leonid Brezhnev led the Soviet Union from 1964 to 1982, a period later termed the Era of Stagnation, or zastoi, for its declining economic growth and resistance to reform. Soviet GNP growth, which had averaged around 5 percent annually in the 1960s, slowed to 1 to 2 percent per year by the late 1970s and early 1980s as the economy leaned ever more heavily on oil exports and military spending while consumer goods stayed scarce. When reformist trends in Czechoslovakia's 1968 Prague Spring threatened Communist rule there, Brezhnev sent Warsaw Pact troops to crush the movement in August 1968, and in a November 1968 speech declared that a threat to socialist rule in any Eastern Bloc state was a threat to all of them, a position that became known as the Brezhnev Doctrine and later justified the 1979 invasion of Afghanistan as well.
Why it matters
The stagnation of Brezhnev's later years, especially the widening gap between Soviet and Western living standards and technology, is what Mikhail Gorbachev would cite in the 1980s as the reason perestroika and glasnost were necessary, though those reforms would end up dismantling the system rather than saving it.
How we know
Soviet economic planning records and later comparative economic analysis document the growth slowdown; the Brezhnev Doctrine's text and the 1968 invasion of Czechoslovakia are documented in contemporary US and Soviet diplomatic records.
