Respuesta :
the Soviet Union silenced revolts in Poland and Ukraine
Explanation:
- Limited democratization of the USSR began in the second half of the 1980s, under the leadership of M. S. Gorbachev (→ perestroika); relations with the US and Western European countries were improved, there was a Soviet military withdrawal from Afghanistan (1988-89) and Central Europe (1990-91), and the dissolution of the SEV and the Warsaw Pact (1991).
- Due to the weakening of central Soviet power, internal conflicts erupted (Armenian-Azerbaijani, since 1988) and republican demands for independence emerged (since 1990).
- The strengthening of the power of Russian President B. Yeltsin led to the dissolution of the USSR (21 XII. 1991) and the resignation of Soviet President Gorbachev (25 XII. 1991); in international relations, the position of the USSR was inherited by Russia.
