Post-Soviet transition in Ukraine
The Ukrainian Soviet Socialist Republic was one of the founding states of the Soviet Union (USSR). In 1985, Mikhail Gorbachev became head of state of the USSR and introduced a number of policies, such as the perestroika and glasnost. Instead of saving the Soviet regime, the reforms triggered a number of popular upheavals in Europe, such as the fall of the Berlin Wall in 1989.
