Beginning in the late 1980s, under Mikhail Gorbachev, the new political and social freedoms resulted in many church buildings being returned to the church, to be restored by local parishioners. A pivotal point in the history of the Russian Orthodox Church came in 1988, the millennial anniversary of the Christianization of Kievan Rus'. Throughout the summer of that year, major government-supported celebrations took place in Moscow and other cities; many older churches and some monasteries were reopened. An implicit ban on religious propaganda on state TV was finally lifted. For the first time in the history of the Soviet Union, people could see live transmissions of church services on television.
