The Republics of the Union of Soviet Socialist Republics or the Union Republics were national-based administrative units of the Union of Soviet Socialist Republics (USSR). The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russian SFSR (RSFSR), Transcaucasian Federation, and Ukraine, by which they became its constituent republics of the Union of Soviet Socialist Republics.
The Singing Revolution was a series of events from 1987 to 1991 that led to the restoration of independence of the three Soviet-occupied Baltic countries of Estonia, Latvia, and Lithuania at the end of the Cold War. The term was coined by an Estonian activist and artist, Heinz Valk, in an article published a week after the 10–11 June 1988 spontaneous mass evening singing demonstrations at the Tallinn Song Festival Grounds.
The Latvian Soviet Socialist Republic was de facto one of the constituent republics of the Soviet Union between 1940–1941 and 1944–1990.
The Popular Front of Latvia was a political organisation in Latvia in the late 1980s and early 1990s which led Latvia to its independence from the Soviet Union. It was similar to the Popular Front of Estonia and the Sąjūdis movement in Lithuania.
Edgar Savisaar was an Estonian politician, one of the founding members of Popular Front of Estonia and the Centre Party. He served as the acting Prime Minister of Estonia, Minister of the Interior, Minister of Economic Affairs and Communications, and twice mayor of Tallinn.
The Sąjūdis, initially known as the Reform Movement of Lithuania, is a political organisation which led the struggle for Lithuanian independence in the late 1980s and early 1990s. It was established on 3 June 1988 as the first opposition party in Soviet Lithuania, and was led by Vytautas Landsbergis. Its goal was to seek the return of independent status for Lithuania.
The Baltic Way or Baltic Chain was a peaceful political demonstration that occurred on 23 August 1989. Approximately two million people joined their hands to form a human chain spanning 690 kilometres (430 mi) across the three Baltic states of Estonia, Latvia and Lithuania, which at the time were occupied and annexed by the USSR and had a combined population of approximately eight million. The central government in Moscow considered the three Baltic countries constituent republics of the Soviet Union.
The Belarusian Popular Front "Revival" was a social and political movement in Belarus in the late 1980s and 1990s whose goals were national revival of Belarus, its democratization and independence from the Soviet Union.

Kazimira Danutė Prunskienė is a Lithuanian politician who was the first prime minister of Lithuania after the declaration of independence on 11 March 1990, and then Minister of Agriculture in the government of Gediminas Kirkilas.
The Act of the Re-Establishment of the State of Lithuania or Act of 11 March was an independence declaration by Lithuania adopted on 11 March 1990, signed by all members of the Supreme Council of the Republic of Lithuania led by Sąjūdis. The act emphasized restoration and legal continuity of the interwar-period Lithuania, which was occupied by the Soviet Union and annexed in June 1940. In March 1990, it was the first of the 15 Soviet republics to declare independence, with the rest following to continue for 21 months, concluding with Kazakhstan's independence in 1991. These events led to the dissolution of the Soviet Union in December 1991.
The Intermovement(International Movement of Workers in the Estonian Soviet Socialist Republic) was a political movement and organisation in the Estonian SSR. It was founded on 19 July 1988 and claimed by different sources 16,000 - 100,000 members. The original name of the movement was Interfront, which was changed to Intermovement in autumn 1988.
Interfront was a pro-communist political movement that aimed to preserve the Soviet Union as a unified Marxist–Leninist state and strongly opposed the pro-independence movements in the republics. It had branches in Estonia, Latvia, Lithuania, Moldova, Ukraine and other union republics.
The New Union Treaty was a draft treaty that would have replaced the 1922 Treaty on the Creation of the Union of Soviet Socialist Republics (USSR) to salvage and reform the USSR. A ceremony of the Russian SFSR signing the treaty was scheduled for 20 August 1991 but was prevented by the August Coup a day earlier.
The Estonian National Independence Party, or ENIP,, founded on 20 August 1988 in Estonian SSR, was the first non-communist political party established in the former USSR. Founders of the party were nationalist and anti-communist dissidents.
The Barricades were a series of confrontations between the Republic of Latvia and the Union of Soviet Socialist Republics in January 1991 which took place mainly in Riga. The events are named for the popular effort of building and protecting barricades from 13 January until about 27 January. Latvia, which had declared restoration of independence from the Soviet Union a year earlier, anticipated that the Soviet Union might attempt to regain control over the country by force.
Relevant events began regarding the Baltic states and the Soviet Union when, following Bolshevist Russia's conflict with the Baltic states—Lithuania, Latvia and Estonia—several peace treaties were signed with Russia and its successor, the Soviet Union. In the late 1920s and early 1930s, the Soviet Union and all three Baltic States further signed non-aggression treaties. The Soviet Union also confirmed that it would adhere to the Kellogg–Briand Pact with regard to its neighbors, including Estonia and Latvia, and entered into a convention defining "aggression" that included all three Baltic countries.
Yedinstvo was a pro-soviet and anti-Sąjūdis movement in the Lithuanian SSR during the Perestroika era. The goals of the movement were similar to those of the Latvian and Estonian Internationalist Movements, e.g. opposition to disintegration of the Soviet Union. Yedinstvo was supported by the Soviet military and the KGB.
The three Baltic states – Estonia, Latvia and Lithuania – were re-occupied in 1944–1945 by the Soviet Union (USSR) following the German occupation. The Baltic states regained independence in 1990–1991.
The Union of Soviet Socialist Republics (USSR) was formally dissolved as a sovereign state and subject of international law on 26 December 1991 by Declaration № 142-Н of the Soviet of the Republics of the Supreme Soviet of the Soviet Union. It also brought an end to the Soviet Union's federal government and General Secretary Mikhail Gorbachev's effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of 15 top-level republics that served as the homelands for different ethnicities. Annexation of at least 3 of them by Soviet Union during the World War II was never fully recognized. By late 1991, amid a catastrophic political crisis, with several republics already departing the Union and Gorbachev continuing the waning of centralized power, the leaders of three of its founding members, the Russian, Belorussian, and Ukrainian SSRs, declared that the Soviet Union no longer existed. Eight more republics joined their declaration shortly thereafter. Gorbachev resigned on 25 December 1991 and what was left of the Soviet parliament voted to dissolve the union.
The Soviet economic blockade of Lithuania was imposed by the Soviet Union on Lithuania between 18 April and 2 July 1990.
