After Leonid Brezhnev assumed power in 1964, much of Khrushchev's reforms were reversed. The Brezhnev era began a new state of stagnation, and saw a decline in both the quality and quantity of products in the Soviet Union. Armenia was severely affected by these policies, as was to be demonstrated several years later in the catastrophic earthquake that hit Spitak. Material allocated to the building of new homes, such as cement and concrete, was diverted for other uses. Bribery and a lack of oversight saw the construction of shoddily built and weakly supported apartment buildings. When the earthquake hit on the morning of 7 December 1988, the houses and apartments least able to resist collapse were those built during the Brezhnev years. Ironically, the older the dwellings, the better they withstood the quake.
