Answer:
The dissolution of the Soviet Union (1988–1991)[b] was the process of internal disintegration within the USSR, which began with growing unrest in its various constituent republics developing into an incessant political and legislative conflict between the republics and the central government, and ended when the leaders of three primal republics (the Russian SFSR, the Ukrainian SSR and the Byelorussian SSR) declared it no longer existed, later accompanied by 11 more republics, resulting in President Mikhail Gorbachev having to resign and what was left of the Soviet parliament formally acknowledging what had already taken place.
The failure of the 1991 August Coup, when Soviet government and military elites tried to overthrow Gorbachev and stop the "parade of sovereignties", led to the government in Moscow losing most of its influence, and many republics proclaiming independence in the following days and months. The secession of the Baltic states, the first to declare their sovereignty and then their full independence, was recognized in September 1991. The Belovezha Accords were signed on December 8 by President Boris Yeltsin of Russia, President Leonid Kravchuk of Ukraine, and Chairman Stanislav Shushkevich of Belarus, recognising each other's independence and creating the Commonwealth of Independent States (CIS). The remaining republics, with the exception of Georgia, joined the CIS on December 21, signing the Alma-Ata Declaration[2]
On December 25, President Mikhail Gorbachev resigned, declared his office extinct, and handed over its powers—including control of the nuclear launch codes—to Yeltsin. That evening at 7:32 p.m., the Soviet flag was lowered from the Kremlin for the last time and replaced with the Russian national flag.[2] On the next day, the Declaration 142-Н of the Supreme Soviet's upper chamber, the Soviet of the Republics, recognised self-governing independence for the Soviet republics, formally dissolving the Union.[1][3] Both the Revolutions of 1989 in the Eastern Bloc and the dissolution of the Soviet Union marked the end of the Cold War.
In the aftermath of the Cold War, several of the former Soviet republics have retained close links with Russia and formed multilateral organizations such as the CIS, the Eurasian Economic Community, the Union State, the Eurasian Customs Union, and the Eurasian Economic Union, for economic and military cooperation. On the other hand, the Baltic states and the former Eastern Bloc countries joined NATO and the European Union, while Georgia and Ukraine have distanced themselves from Russia and express interest in following the same path.
