 From 1985 onwards, the last Soviet leader Mikhail Gorbachev, who sought to enact liberal reforms in the Soviet system, introduced the policies of "glasnost" (openness) and "perestroika" (restructuring) in an attempt to end the period of economic stagnation and to democratise the government.This, however, led to the rise of strong nationalist and separatist movements.Prior to 1991, the Soviet economy was the second largest in the world, but during its last years it was afflicted by shortages of goods in grocery stores, huge budget deficits, and explosive growth in the money supply leading to inflation.
