The Soviet Union was formally dissolved and ceased to exist as a sovereign state and subject of international law on 26 December 1991. It also brought an end to the Soviet Union's federal government and to Soviet leader Mikhail Gorbachev's efforts to reform the Soviet political and economic system in an attempt to stop a period of political and economic stagnation.

The collapse of the Soviet Union in 1991 resulted from several factors: chronic economic stagnation, the unsustainable financial burden of the arms race with the United States and foreign conflicts, intense ethnic nationalism and separatism within its union republics, and the destabilizing effects of Gorbachev's reforms (particularly glasnost and perestroika).

The process began with growing unrest in the country's union republics developing into an incessant political and legislative conflict between them and the central government. Until its final years, the Soviet Union was made up of 15 union republics that served as the homelands of different ethnic groups. Estonia was the first union republic to declare state sovereignty on 16 November 1988. Lithuania was the first republic to declare independence, in March 1990.

During the failed 1991 August coup, communist hardliners attempted to overthrow Gorbachev and reverse his reforms. However, the turmoil caused the central government in Moscow to lose influence, ultimately leading many republics to declare independence in the following days and months. On 8 December 1991, the leaders of its three founding republics—the Russian SFSR, the Byelorussian SSR, and the Ukrainian SSR—signed the Belovezh Accords and declared that the Soviet Union no longer existed. Eight more republics joined the declaration shortly thereafter. The Belovezha Accords also established the Commonwealth of Independent States (CIS) to replace the Soviet Union as a community. Kazakhstan was the last republic to declare independence, on 16 December. All post-Soviet states, with the exception of Georgia and the Baltic states, joined the CIS on 21 December by signing the Alma-Ata Protocol. Russia, as by far the largest and most populous republic, became the Soviet Union's recognized successor state.

On 25 December 1991, Gorbachev resigned and transferred his presidential powers—including control of the nuclear launch codes—to Russian president Boris Yeltsin. That evening, the Soviet flag was lowered from the Moscow Kremlin for the last time and replaced with the Russian tricolor. The following day, the Soviet of the Republics, the upper chamber of the Supreme Soviet of the Soviet Union, formally dissolved the Soviet Union by adopting Declaration No. 142-N. The dissolution marked the culmination of the Revolutions of 1989 and the end of the Cold War.

In the aftermath of the Cold War, several of the post-Soviet states have retained close links with Russia and formed multilateral organizations such as the CIS and the Collective Security Treaty Organization (CSTO).

Background

1985: Gorbachev elected

Mikhail Gorbachev was elected General Secretary by the Politburo on 11 March 1985, just over four hours after his predecessor Konstantin Chernenko died at the age of 73. Gorbachev, aged 54, was the youngest member of the Politburo. His initial goal as general secretary was to revive the stagnating Soviet economy, and he realized that doing so would require reforming underlying political and social structures. The reforms began with personnel changes of senior Brezhnev-era officials who would impede political and economic change. On 23 April 1985, Gorbachev brought two protégés, Yegor Ligachev and Nikolai Ryzhkov, into the Politburo as full members. He kept the "power" ministries favorable by promoting KGB Chief Viktor Chebrikov from candidate to full member and appointing Minister of Defence Marshal Sergei Sokolov as a Politburo candidate.

The freedom of speech brought by Gorbachev's reforms allowed nationalist movements and ethnic disputes within the Soviet Union to be expressed and grow into dominant political movements. It also led indirectly to the revolutions of 1989 in which Soviet-imposed socialist regimes of the Warsaw Pact were toppled peacefully (with the notable exception of Romania), which in turn increased pressure on Gorbachev to introduce greater democracy and autonomy for the Soviet Union's constituent republics. Under Gorbachev's leadership, the Communist Party of the Soviet Union (CPSU) in 1989 introduced limited competitive elections to a new central legislature, the Congress of People's Deputies (although the ban on other political parties was not lifted until 1990).

On 1 July 1985, Gorbachev sidelined his main rival by removing Grigory Romanov from the Politburo and brought Boris Yeltsin into the Central Committee Secretariat. On 23 December 1985, Gorbachev appointed Yeltsin First Secretary of the Moscow Communist Party, replacing Viktor Grishin.

1986: Sakharov returns

Gorbachev continued to press for greater liberalization. On 23 December 1986 Andrei Sakharov, the most prominent Soviet dissident, returned to Moscow shortly after receiving a personal telephone call from Gorbachev telling him that after almost seven years his internal exile for defying the authorities was over.

1987: One-party democracy

At the 28–30 January Central Committee plenum, Gorbachev suggested a new policy of demokratizatsiya, or "democratization", throughout Soviet society. He proposed that future Communist Party elections should offer a choice between multiple candidates, elected by secret ballot. However, the party delegates at the Plenum watered down Gorbachev's proposal, and democratic choice within the Communist Party was never significantly implemented.

Gorbachev also radically expanded the scope of glasnost, and stated that no subject was off limits for open discussion in the media. On 7 February, dozens of political prisoners were freed in the first group release since the Khrushchev thaw in the mid-1950s.

On 10 September, Boris Yeltsin wrote a letter of resignation to Gorbachev. At the 27 October plenary meeting of the Central Committee, Yeltsin, frustrated that Gorbachev had not addressed any of the issues outlined in his resignation letter, criticized the slow pace of reform, and servility to the general secretary. In his reply, Gorbachev accused Yeltsin of "political immaturity" and "absolute irresponsibility".

Nevertheless, news of Yeltsin's insubordination and "secret speech" spread, and soon samizdat versions began to circulate. That marked the beginning of Yeltsin's rebranding as a rebel and rise in popularity as an anti-establishment figure. The following four years of political struggle between Yeltsin and Gorbachev played a large role in the dissolution of the Soviet Union. On 11 November, Yeltsin was fired from the post of First Secretary of the Moscow City Committee of the Communist Party of the Soviet Union.

Protest activity (1986-1987)

In the years leading up to the dissolution, various protests and resistance movements occurred or took hold throughout the Soviet Union, which were variously suppressed or tolerated.

In the Baltics, several protest groups were established against Soviet rule, such as Helsinki-86, the Popular Front of Latvia, Sąjūdis, and the Popular Front of Estonia. Helsinki-86 was the first openly anti-Communist organization in the Soviet Union, and the first openly organized opposition to the Soviet regime, setting an example for other ethnic minorities' pro-independence movements.

On 26 December 1986, 300 Latvian youths gathered in Riga's Cathedral Square and marched down Lenin Avenue toward the Freedom Monument, shouting, "Soviet Russia out! Free Latvia!" Security forces confronted the marchers, and several police vehicles were overturned.

The Jeltoqsan ('December') of 1986 were riots in Alma-Ata, Kazakhstan, sparked by Gorbachev's dismissal of Dinmukhamed Kunaev, the First Secretary of the Communist Party of Kazakhstan and an ethnic Kazakh, who was replaced with Gennady Kolbin, an outsider from the Russian SFSR. Demonstrations started in the morning of 17 December 1986, with 200 to 300 students in front of the Central Committee building on Brezhnev Square. On the next day, 18 December, protests turned into civil unrest as clashes between troops, volunteers, militia units, and Kazakh students turned into a wide-scale confrontation. The clashes could only be controlled on the third day.

On 6 May 1987, Pamyat, a Russian nationalist group, held an unsanctioned demonstration in Moscow. The authorities did not break up the demonstration and even kept traffic out of the demonstrators' way while they marched to an impromptu meeting with Boris Yeltsin.

On 14 June 1987, about 5,000 people gathered again at Freedom Monument in Riga, and laid flowers to commemorate the anniversary of Stalin's mass deportation of Latvians in 1941. The authorities did not crack down on demonstrators, which encouraged more and larger demonstrations throughout the Baltic States. On 18 November 1987, hundreds of police and civilian militiamen cordoned off the central square to prevent any demonstration at Freedom Monument, but thousands lined the streets of Riga in silent protest regardless.

On 25 July 1987, 300 Crimean Tatars staged a noisy demonstration near the Kremlin Wall for several hours, calling for the right to return to their homeland, from which they were deported in 1944; police and soldiers looked on.

On 23 August 1987, the 48th anniversary of the secret protocols of the 1939 Molotov Pact, thousands of demonstrators marked the occasion in the three Baltic capitals to sing independence songs and attend speeches commemorating Stalin's victims. The gatherings were sharply denounced in the official press and closely watched by the police but were not interrupted.

On 17 October 1987, a protest held in Armenia SSR was underway. The following day 1,000 Armenians participated in another demonstration calling for Armenian national rights in Karabakh, and the proposed unification of both Nakhchivan and Nagorno-Karabakh to Armenia. The police tried to physically prevent the march and after a few incidents, dispersed the demonstrators.

Timeline

1988

Moscow loses control

In 1988, Gorbachev started to lose control of two regions of the Soviet Union, as the Baltic republics were now leaning towards independence, and the Caucasus descended into violence and civil war.

On 1 July 1988, the fourth and last day of a bruising 19th Party Conference, Gorbachev won the backing of the tired delegates for his last-minute proposal to create a new supreme legislative body called the Congress of People's Deputies. Frustrated by the old guard's resistance, Gorbachev embarked on a set of constitutional changes to attempt separation of party and state, thereby isolating his Party opponents. Detailed proposals for the new Congress of People's Deputies were published on 2 October 1988, and to enable the creation of the new legislature. The Supreme Soviet, during its 29 November – 1 December 1988, session, implemented amendments to the 1977 Soviet Constitution, enacted a law on electoral reform, and set the date of the election for 26 March 1989.

On 29 November 1988, the Soviet Union ceased jamming all foreign radio stations, allowing Soviet citizens – for the first time since a brief period in the 1960s – to have unrestricted access to news sources beyond Communist Party control.

Baltic republics

In 1986 and 1987, Latvia had been in the vanguard of the Baltic states in pressing for reform. In 1988, Estonia took over the lead role with the foundation of the Soviet Union's first popular front and starting to influence state policy.

The Popular Front of Estonia was founded in April 1988. On 16 June 1988, Gorbachev replaced Karl Vaino, the "old guard" leader of the Communist Party of Estonia, with the comparatively liberal Vaino Väljas. In late June 1988, Väljas bowed to pressure from the Estonian Popular Front and legalized the flying of the old blue-black-white flag of Estonia, and agreed to a new state language law that made Estonian the official language of the Republic.

On 2 October, the Popular Front formally launched its political platform at a two-day congress. Väljas attended, gambling that the Front could help Estonia become a model of economic and political revival, while moderating separatist and other radical tendencies. On 16 November 1988, the Supreme Soviet of the Estonian SSR adopted a declaration of national sovereignty under which Estonian laws would take precedence over those of the Soviet Union. Estonia's parliament also laid claim to the republic's natural resources including land, inland waters, forests, mineral deposits, and to the means of industrial production, agriculture, construction, state banks, transportation, and municipal services within the territory of Estonia's borders. At the same time the Estonian Citizens' Committees started registration of citizens of the Republic of Estonia to carry out the elections of the Congress of Estonia.

The Popular Front of Latvia was founded in June 1988. On 4 October, Gorbachev replaced Boris Pugo, the "old guard" leader of the Communist Party of Latvia, with the more liberal Jānis Vagris. In October 1988 Vagris bowed to pressure from the Latvian Popular Front and legalized flying the former carmine red-and-white flag of independent Latvia, and on 6 October he passed a law making Latvian the country's official language.

The Popular Front of Lithuania, called Sąjūdis ("Movement"), was founded in May 1988. On 19 October 1988, Gorbachev replaced Ringaudas Songaila, the "old guard" leader of the Communist Party of Lithuania – who had been in office for nearly a year – with the relatively liberal Algirdas Brazauskas. In October 1988, Brazauskas bowed to pressure from Sąjūdis members, and legalized the flying of the historic yellow-green-red flag of independent Lithuania, and in November 1988 he passed a law making Lithuanian the country's official language; also, the former national anthem, "Tautiška giesmė", was later reinstated. Following a violent protest action in the capital on 28 October, many of Songalia's remaining holdovers within the CPL either resigned or retired in protest of the police brutality of that day.

Rebellion in the Caucasus

On 20 February 1988, after a week of growing demonstrations in Stepanakert, capital of the Nagorno-Karabakh Autonomous Oblast (the ethnically Armenian-majority area within the Azerbaijan Soviet Socialist Republic), the Regional Soviet voted to secede and join with the Soviet Socialist Republic of Armenia. This local vote in a small, remote part of the Soviet Union made headlines around the world; it was an unprecedented defiance of republican and national authorities. On 22 February 1988, in what became known as the "Askeran clash", thousands of Azerbaijanis marched towards Nagorno-Karabakh, demanding information about rumors of an Azerbaijani having been killed in Stepanakert. They were informed by officials that no such incident had occurred; however, dissatisfied with what they were told, they began marching toward Nagorno-Karabakh, killing (or injuring?) 50. Karabakh authorities mobilised over a thousand police to stop the march, with the resulting clashes leaving two Azerbaijanis dead. These deaths, announced on state radio, led to the Sumgait pogrom. Between 26 February and 1 March, the city of Sumgait (Azerbaijan) saw violent anti-Armenian rioting during which at least 32 people were killed. The authorities totally lost control and occupied the city with paratroopers and tanks; nearly all of the 14,000 Armenian residents of Sumgait fled.

Gorbachev refused to make any changes to the status of Nagorno-Karabakh, which remained part of Azerbaijan. He instead sacked the Communist Party Leaders in both Republics in response – on 21 May 1988, Kamran Baghirov was replaced by Abdurrahman Vazirov as First Secretary of the Azerbaijan Communist Party. From 23 July to September 1988, a group of Azerbaijani intellectuals began working for a new organization called the Popular Front of Azerbaijan, loosely based on the Estonian Popular Front. On 17 September, when gun battles broke out between the Armenians and Azerbaijanis near Stepanakert, two soldiers were killed and more than two dozen injured. This led to almost tit-for-tat ethnic polarization in Nagorno-Karabakh's two main towns: the Azerbaijani minority was expelled from Stepanakert, and the Armenian minority was expelled from Shusha. On 17 November 1988, in response to the exodus of tens of thousands of Azerbaijanis from Armenia, a series of mass demonstrations began in Baku's Lenin Square, lasting 18 days and attracting half a million demonstrators in support of their compatriots in that region. On 5 December 1988, the Soviet police and civilian militiamen moved in, cleared the square by force, and imposed a curfew that lasted ten months.

The rebellion of fellow Armenians in Nagorno-Karabakh had an immediate effect in Armenia itself. Daily demonstrations, which began in the Armenian capital Yerevan on 18 February, initially attracted few people, but each day the Nagorno-Karabakh issue became increasingly prominent and the numbers swelled. On 20 February, a 30,000-strong crowd demonstrated in the Theater Square, by 22 February, there were 100,000, the next day 300,000, and a transport strike was declared, by 25 February, there were close to a million demonstrators – more than a quarter of Armenia's population. This was the first of the large, peaceful public demonstrations that would become a feature of communism's overthrow in Prague, Berlin, and, ultimately, Moscow. Leading Armenian intellectuals and nationalists, including the future first president of independent Armenia Levon Ter-Petrosyan, formed the eleven-member Karabakh Committee to lead and organize the new movement.

Also on 21 May, Gorbachev replaced Karen Demirchyan with Suren Harutyunyan as First Secretary of the Communist Party of Armenia. However, Harutyunyan quickly changed course and on 28 May, allowed Armenians to unfurl the red-blue-orange First Armenian Republic flag for the first time in almost 70 years to mark the 1918 declaration of the First Republic. On 15 June 1988, the Armenian Supreme Soviet adopted a resolution formally approving the idea of Nagorno-Karabakh's unification as part of the republic. Armenia, formerly one of the most loyal republics, had suddenly turned into the leading rebel republic. On 5 July 1988, when a contingent of troops was sent in to remove demonstrators by force from Yerevan's Zvartnots International Airport, shots were fired and one student protester was killed. In September, further large demonstrations in Yerevan led to the deployment of armored vehicles. In the autumn of 1988 almost all of the 200,000 Azerbaijani minority in Armenia was expelled by Armenian nationalists, with over 100 killed in the process. That, after the Sumgait pogrom earlier that year, which had been carried out by Azerbaijanis to ethnic Armenians and led to the expulsion of Armenians from Azerbaijan, was for many Armenians considered an act of revenge for the killings at Sumgait. On 25 November 1988, a military commandant took control of Yerevan as the Soviet government moved to prevent further ethnic violence.

On 7 December 1988, the Spitak earthquake struck, killing an estimated 25,000 to 50,000 people. When Gorbachev rushed back from a visit to the United States, he was so angered with being confronted by protesters calling for Nagorno-Karabakh to be made part of the Armenian Republic during a natural disaster that on 11 December 1988, he ordered that the entire Karabakh Committee be arrested.

In Tbilisi, the capital of Soviet Georgia, many demonstrators camped out in front of the republic's legislature in November 1988 calling for Georgia's independence and in support of Estonia's declaration of sovereignty.

Western republics

Beginning in February 1988, the Democratic Movement of Moldova, later the Popular Front of Moldova, organized public meetings, demonstrations, and song festivals, which gradually grew in size and intensity. In the streets, the center of public manifestations was the Stephen the Great Monument in Chișinău, and the adjacent park harboring Aleea Clasicilor (The "Alley of Classics [of Literature]"). The transition from "movement" (an informal association) to "front" (a formal association) was seen as a natural "upgrade" once a movement gained momentum with the public, and the Soviet authorities no longer dared to crack down on it.

On 26 April 1988, about 500 people participated in a march organized by the Ukrainian Cultural Club on Kiev's Khreshchatyk Street to mark the second anniversary of the Chernobyl nuclear disaster, carrying placards with slogans like "Openness and Democracy to the End". Between May and June 1988, Ukrainian Catholics in western Ukraine celebrated the Millennium of Christianity in Kievan Rus' in secret by holding services in the forests of Buniv, Kalush, Hoshi, and Zarvanytsia. On 5 June 1988, as the official celebrations of the Millennium were held in Moscow, the Ukrainian Cultural Club hosted its own observances in Kiev at the monument to Vladimir the Great, the grand prince of Kievan Rus'.

On 16 June 1988, 6,000 to 8,000 people gathered in Lviv to hear speakers declare no confidence in the local list of delegates to the 19th Communist Party conference, to begin on 29 June. On 21 June, a rally in Lviv attracted 50,000 people who had heard about a revised delegate list. Authorities attempted to disperse the rally in front of Druzhba Stadium. On 7 July, 10,000 to 20,000 people witnessed the launch of the Democratic Front to Promote Perestroika. On 17 July, a group of 10,000 gathered in the village Zarvanytsia for Millennium services celebrated by Ukrainian Greek-Catholic Bishop Pavlo Vasylyk. The militia tried to disperse attendees, but it turned out to be the largest gathering of Ukrainian Catholics since Stalin outlawed the Church in 1946. On 4 August, which came to be known as "Bloody Thursday", local authorities violently suppressed a demonstration organized by the Democratic Front to Promote Perestroika. Forty-one people were detained, fined, or sentenced to 15 days of administrative arrest. On 1 September, local authorities violently displaced 5,000 students at a public meeting lacking official permission at Ivan Franko State University.

On 13 November 1988, approximately 10,000 people attended an officially sanctioned meeting organized by the cultural heritage organization Spadschyna, the Kiev University student club Hromada, and the environmental groups Zelenyi Svit ("Green World") and Noosfera, to focus on ecological issues. From 14 to 18 November, 15 Ukrainian activists were among the 100 human-, national- and religious-rights advocates invited to discuss human rights with Soviet officials and a visiting delegation of the U.S. Commission on Security and Cooperation in Europe (also known as the Helsinki Commission). On 10 December, hundreds gathered in Kiev to observe International Human Rights Day at a rally organized by the Democratic Union. The unauthorized gathering resulted in the detention of local activists.

The Belarusian Popular Front was established in 1988 as a political party and cultural movement for democracy and independence, similar to the Baltic republics' popular fronts. The discovery of mass graves in Kurapaty outside Minsk by historian Zianon Pazniak, the Belarusian Popular Front's first leader, gave additional momentum to the pro-democracy and pro-independence movement in Belarus. It claimed that the NKVD performed secret killings in Kurapaty. Initially the Front had significant visibility because its numerous public actions almost always ended in clashes with the police and the KGB.

1989

Moscow: limited democratization

Spring 1989 saw the people of the Soviet Union exercising a democratic choice, albeit limited, for the first time since 1917, when they elected the new Congress of People's Deputies. Just as important was the uncensored live TV coverage of the legislature's deliberations, where people witnessed the previously feared Communist leadership being questioned and held accountable. This example fueled a limited experiment with democracy in Poland, which quickly led to the toppling of the Communist government in Warsaw that summer and in turn sparked uprisings that overthrew governments in the other five Warsaw Pact countries before the end of 1989, the year the Berlin Wall fell.

This was also the year that CNN became the first non-Soviet broadcaster allowed to beam its TV news programs to Moscow. Officially, CNN was available only to foreign guests in the Savoy Hotel, but Muscovites quickly learned how to pick up signals on their home televisions. That had a major effect on how Soviets saw events in their country and made censorship almost impossible.

The month-long nomination period for candidates for the Congress of People's Deputies of the Soviet Union lasted until 24 January 1989. For the next month, selection among the 7,531 district nominees took place at meetings organized by constituency-level electoral commissions. On 7 March, a final list of 5,074 candidates was published; about 85% were Party members.

In the two weeks prior to the 1,500 district polls, elections to fill 750 reserved seats of public organizations, contested by 880 candidates, were held. Of these seats, 100 were allocated to the CPSU, 100 to the All-Union Central Council of Trade Unions, 75 to the Communist Youth Union (Komsomol), 75 to the Committee of Soviet Women, 75 to the War and Labour Veterans' Organization, and 325 to other organizations such as the Academy of Sciences. The selection process was done in April.

In the 26 March general elections, voter participation was an impressive 89.8%, and 1,958 (including 1,225 district seats) of the 2,250 CPD seats were filled. In district races, run-off elections were held in 76 constituencies on 2 and 9 April and fresh elections were organized on 14 and 20 April to 23 May, in the 199 remaining constituencies where the required absolute majority was not attained. While most CPSU-endorsed candidates were elected, more than 300 lost to independent candidates such as Yeltsin, the physicist Andrei Sakharov and the lawyer Anatoly Sobchak.
