perestroika refers to a series of political and economic reforms meant to kickstart the stagnant 1980s economy of the soviet union. its architect, president mikhail gorbachev, would oversee the most fundamental changes to his nation’s economic engine and political structure since the russian revolution. but the suddenness of these reforms, coupled with growing instability both inside and out of the soviet union, would contribute to the collapse of the u.s.s.r. in 1991.present-day inefficiencies, gorbachev moved to remake much of the political system of the u.s.s.r.

at a party meeting in 1988, he pushed through measures calling for the first truly democratic elections since the russian revolution of 1917. hardliners who supported this initially believed that the date for these elections would be far enough in the future that they could control the process. instead, gorbachev announced that they would be held just months later.
