Why the USSR Collapsed Despite the 1991 Referendum

On 17 March 1991, millions of Soviet citizens lined up at polling stations from Minsk to Tashkent. When the ballots were counted, 77.8% of those who voted said they wanted to preserve the USSR as a “renewed federation of equal sovereign republics.” Nine months later, the Soviet Union was dead and buried.

So what happened between March and December 1991? Why did the USSR collapse under Mikhail Gorbachev even though a clear majority of voters supported keeping it? The short answer: the referendum result arrived too late, asked the wrong question, and could not rescue a state whose political center, economic system, and security apparatus were already coming apart.

What was the 1991 Soviet referendum, really?

The March 1991 all-Union referendum was the first and only nationwide referendum in Soviet history. The official question was whether to preserve the USSR as a “renewed federation of equal sovereign republics, in which the rights and freedoms of a person of any nationality will be fully guaranteed.”

On paper, it looked like a massive mandate. Turnout was reported at about 80%. Of those who voted, nearly 78% said “yes.” In Russia, 71% voted to preserve the Union. In Ukraine, 70.2% did. In Central Asia and Belarus, support was even higher.

But the headline number hides several problems.

First, six republics boycotted the referendum entirely: Lithuania, Latvia, Estonia, Georgia, Armenia, and Moldova. These were not marginal territories. They included the entire Baltic region and most of the Caucasus, where independence movements were strong and often backed by mass protests.

Second, the question itself was vague. Voters were not asked whether they wanted to preserve the USSR in its existing form. They were asked about a hypothetical “renewed federation” that did not yet exist and had no clear constitutional shape. People could project very different hopes onto that phrase.

Third, the Soviet state apparatus that organized and reported the referendum was already under strain. While there is no consensus that the results were fabricated on a massive scale, the climate of pressure, propaganda, and uneven media access makes it hard to treat the numbers as a clean expression of free, informed consent.

Most important, the referendum was consultative, not binding. It did not create a new constitution or automatic legal obligations. It was a political signal, not a legal shield. Once power in the republics shifted away from Moscow later in 1991, that signal could be ignored.

So the referendum showed that many ordinary Soviet citizens wanted some kind of continued union, but it did not guarantee that the political elites who actually controlled armies, budgets, and borders would keep that union alive. That gap between popular preference and elite power is where the story of the collapse sits.

What set off the collapse of the USSR under Gorbachev?

By 1991, the Soviet Union was not a stable state suddenly betrayed by one leader. It was a system in long-term crisis that Gorbachev’s reforms exposed and accelerated.

Gorbachev came to power in 1985 promising perestroika (restructuring) and glasnost (openness). He wanted to revive the Soviet system, not destroy it. The economy was stagnating, oil prices had fallen, and the arms race with the United States was draining resources. The old model of central planning was failing to deliver growth or consumer goods.

Perestroika tried to decentralize economic decision-making, give state enterprises more autonomy, and allow limited private activity. Glasnost loosened censorship, allowed more open discussion, and exposed past crimes like Stalin’s terror. Political reforms introduced competitive elections for some bodies, including the new Congress of People’s Deputies.

These reforms had three big unintended effects.

First, they shattered the fear that had kept the system together. Once people could criticize the party and the state, they did, loudly. National grievances, long suppressed, erupted. In the Baltics, the Caucasus, and parts of Russia and Ukraine, independence movements grew from small dissident circles into mass organizations.

Second, economic reforms were half-hearted and contradictory. Prices remained largely controlled, but supply chains were disrupted and central ministries lost authority. The result was not a functioning market but a kind of managed chaos. Shortages worsened, inflation rose, and living standards fell. For many Soviet citizens, perestroika felt like economic collapse, not renewal.

Third, political reforms weakened the Communist Party without creating strong new institutions to replace it. Republic-level leaders, some elected and some still old-guard, discovered they could appeal directly to their own populations against Moscow. Sovereignty declarations spread from the Baltic republics to Russia itself, which proclaimed its own laws supreme over Union law in 1990.

The Soviet Union was a federal state in name, but in practice it had been highly centralized. Once the center began to loosen its grip, the republics grabbed as much power as they could. By the time of the 1991 referendum, the Union was already a shell in many areas, with republican governments controlling media, police, and often local economic decisions.

So by early 1991, Gorbachev was trying to hold a crumbling structure together with new legal formulas and political deals, while the economic and national crises pushed key actors to think about life after the Union.

The turning point: the New Union Treaty and the August coup

The referendum was supposed to give Gorbachev a mandate to negotiate a new Union Treaty. This treaty would redefine the USSR as a looser federation or even confederation, with much more power for the republics. It was his answer to both the independence movements and the economic crisis: keep a common state for defense, currency, and foreign policy, but let republics run their own affairs.

By summer 1991, after months of bargaining, nine republics were ready to sign a new treaty on 20 August. Russia, Ukraine, Belarus, and most Central Asian republics were on board. The Baltics and Georgia were not. Armenia and Moldova were in flux.

To hardliners in Moscow, this looked like the end of the USSR. Senior figures in the Communist Party, the KGB, and the military feared that a looser union would mean the loss of their power, the breakup of the Soviet state, and perhaps prosecution for past actions. They saw Gorbachev as giving away the empire.

On 19 August 1991, the day before the treaty signing, a group of these hardliners launched a coup. They claimed that Gorbachev was ill and formed a State Committee on the State of Emergency. Tanks rolled into Moscow. Censorship was reimposed. The plotters tried to reverse glasnost and perestroika by force.

The coup failed within three days. The plotters were divided and hesitant. Crowds in Moscow, rallied by Russian President Boris Yeltsin, resisted. Parts of the army refused to fire on civilians. Gorbachev, held under house arrest in Crimea, refused to legitimize the coup.

But the failure of the coup did not restore the old Union. It destroyed it.

The coup attempt discredited the Communist Party and the central Soviet institutions that had backed it. Yeltsin banned the Russian Communist Party. The party’s property was seized. Republican leaders, shocked by how close the USSR had come to a hardline rollback, moved faster toward independence or at least full sovereignty.

The New Union Treaty, already controversial, became politically toxic. For nationalists, the coup proved that any union with Moscow was dangerous. For Russian leaders like Yeltsin, it was a chance to build an independent Russian state without Gorbachev above them.

The August coup turned a slow-motion constitutional crisis into a rush for the exits. After it failed, the question was no longer how to reform the Union, but how to manage its breakup without violence.

Who drove the collapse: Gorbachev, Yeltsin, and the republican leaders

Several key figures shaped how and why the USSR disappeared in late 1991. They did not all want the same outcome, and none of them were simply following the referendum’s result.

Mikhail Gorbachev wanted to preserve some form of union until the end. He believed that a large multiethnic state was necessary for security, economic coordination, and global influence. He hoped that a reformed, democratic socialism could hold it together.

But Gorbachev was trapped. He had alienated conservatives with his reforms and radicals with his caution. After the August coup, he returned to Moscow weakened and isolated. He was still formally President of the USSR, but real power was shifting to the republics, especially Russia.

Boris Yeltsin, elected President of the Russian Soviet Federative Socialist Republic (RSFSR) in June 1991, saw an opportunity. He had built his popularity by opposing the Communist Party old guard and by championing Russian sovereignty. After the coup, Yeltsin controlled the key levers of power in Russia: the police, parts of the army, and the economic ministries operating on Russian territory.

Yeltsin’s team concluded that Russia would be better off outside a decaying Union. They wanted control over Russian resources, especially oil and gas, and the ability to pursue their own economic reforms without Gorbachev or other republics blocking them. They also feared that trying to hold the Union together by force would drag Russia into endless conflicts on its periphery.

Republican leaders in Ukraine, Belarus, and Central Asia had their own calculations. In Ukraine, a declaration of independence passed in August 1991, followed by a referendum on 1 December in which over 90% of voters supported independence. This was a clear, direct mandate, unlike the March union referendum’s vague formula. For Ukrainian leaders, that result closed the door on any new union.

Belarusian and Central Asian leaders were less eager to break with Moscow, partly because their economies were deeply tied to Russian markets and subsidies. Many of them were former Communist Party bosses who simply rebranded themselves as presidents of new states. They were open to some kind of loose commonwealth, but not a strong central Soviet government.

By late 1991, the political math was simple. Without Russia and Ukraine, there could be no meaningful USSR. The Baltics were already gone in practice. Georgia was on its own path. The Caucasus was unstable. A union of Russia plus Central Asia and Belarus would have been a very different state, and there was no consensus on how to create it or what to call it.

So when Yeltsin, Ukrainian President Leonid Kravchuk, and Belarusian leader Stanislav Shushkevich met in a hunting lodge in Belavezha Forest in December 1991, they were not bound by the March referendum. They were responding to the August coup, the Ukrainian independence vote, and their own power interests. On 8 December, they signed an agreement declaring that the USSR “as a subject of international law and geopolitical reality” had ceased to exist. They created the Commonwealth of Independent States (CIS) in its place.

Gorbachev was informed after the fact. He protested, but he had no means to reverse the decision. On 25 December 1991, he resigned as President of the USSR. The next day, the Soviet flag was lowered over the Kremlin.

The collapse of the USSR was driven less by popular votes and more by the choices of a small group of leaders who controlled armies, economies, and borders, and who decided that their futures lay outside a single Soviet state.

What did the collapse change for the former Soviet republics?

The end of the USSR was not just a flag change. It rearranged power, economies, and identities across a sixth of the earth’s land surface.

Politically, fifteen new states emerged: Russia, Ukraine, Belarus, the three Baltic states, the three South Caucasus republics, and five in Central Asia. Some moved quickly toward pluralist politics and market reforms. Others slid into authoritarian rule or hybrid systems. Borders that had been administrative lines inside one state became international frontiers with customs posts, visas, and, in some cases, armed conflicts.

Economically, the collapse broke the integrated Soviet planning system. Factories that had relied on inputs from other republics suddenly found themselves in different countries with different currencies and trade rules. Supply chains disintegrated. Inflation soared. In the early 1990s, most of the former Soviet republics experienced deep recessions and sharp falls in living standards.

For Russia, the largest successor state, the 1990s were marked by economic shock therapy, privatization, and the rise of oligarchs. For Central Asia, independence meant both new sovereignty and new vulnerabilities, as they navigated between Russia, China, and the West.

Socially and culturally, millions of people woke up in a different country without moving. Ethnic Russians in the Baltics, Kazakhstan, and Ukraine became minorities in new national states. Questions of language, citizenship, and historical memory became politically charged. In some places, such as the Baltics, this led to relatively peaceful but tense adjustments. In others, like parts of the Caucasus and Moldova, it fed into violent conflicts.

Internationally, the collapse removed one superpower from the global stage. The Cold War ended. The United States emerged as the sole superpower. Nuclear weapons, once under unified Soviet control, were now located in Russia, Ukraine, Belarus, and Kazakhstan, requiring urgent negotiations and security guarantees.

The Soviet collapse reshaped not just internal politics in the former republics, but the entire post–Cold War order that followed.

Why it still matters: the referendum myth and today’s conflicts

The 1991 referendum still appears in debates today, especially in Russian political rhetoric. Some argue that the USSR was destroyed “against the will of the people,” pointing to the 77.8% who voted to preserve it. Others use it to claim that most Ukrainians or Belarusians supposedly wanted to stay in a common state with Russia.

That reading skips over the context. The referendum asked about a renewed, hypothetical union, not the existing USSR. It did not include several republics that were already on the path to independence. It was followed by more specific votes in places like Ukraine, where the December 1991 independence referendum gave a clear mandate for leaving.

More fundamentally, the Soviet collapse shows how states can fall apart even when many citizens prefer unity. When central institutions lose legitimacy, the economy fails, and regional elites see more benefit in going their own way, popular majorities can be politically irrelevant.

The breakup of the USSR still shapes conflicts today, from Russia’s war in Ukraine to tensions in the Caucasus and debates over NATO expansion. Arguments about “historical unity” and “artificial borders” often reach back to 1991 and before, sometimes citing or ignoring the referendum as convenient.

Understanding why the USSR collapsed despite that 77% “yes” vote helps cut through myths. It shows that the end of the Union was not a single decision by Gorbachev, nor a simple act of Western pressure, but the outcome of deep structural crises, clashing national projects, and the choices of leaders who decided that the old state was no longer worth saving.
