Democratisation gave nationalists a chance to win elections and challenge the Soviet Union.
Nationalists gained majorities in several republics' parliaments in the 1990 elections.
In March 1990, the newly elected Lithuanian parliament declared independence from the Soviet Union, leading to economic sanctions imposed by Gorbachev.
Yeltsin insisted in May 1990 that laws made by the Russian parliament were legally superior to Soviet laws, giving Russia more independence from the Soviet Union.
The re-emergence of the old Russian flag and the double-headed eagle, banned by the Soviet government, showed the rise of nationalism in Russia and a desire for independence.
