Make a guess

In August 1991 hardliners tried to seize power from Gorbachev, and the coup failed. What do you think happened next?

  1. Gorbachev returned stronger and held the USSR together.
  2. The hardliners took over a few weeks later.
  3. The USSR broke apart by the end of 1991.
Show the answer

The USSR broke apart by the end of 1991.

The coup discredited the hardliners and weakened Gorbachev. Republic leaders such as Yeltsin took power, and the USSR dissolved in December.

A failing economy, republics demanding self-rule and a failed coup in August 1991 destroyed the power holding the USSR together.

The USSR was a union of republics, including Russia, Ukraine and Belarus, ruled centrally from Moscow. Economic crisis and national movements pushed republic leaders to seek more control over their own institutions and resources. Boris Yeltsin led the Russian republic and challenged Gorbachev, who led the whole USSR. So Russia and the USSR were not the same thing.

Change inside the USSR was not always peaceful. Violence in Lithuania and Latvia in early 1991 showed that Soviet force had not disappeared at home, even though it was no longer used in Eastern Europe.

In August 1991, hardliners who wanted to stop reform tried a coup, a sudden seizure of power, against Gorbachev. It failed. But it showed that Gorbachev could not control his own leadership. Yeltsin's public stand against the coup made him and other leaders outside Moscow's centre stronger. So the failed coup weakened central communist power instead of restoring it, and more republics moved towards independence.

In December, the leaders of Russia, Ukraine and Belarus declared that the USSR no longer existed. They formed the Commonwealth of Independent States, a loose group of separate countries rather than one Soviet government. Other republics joined. Gorbachev resigned on 25 December, and the USSR formally ended on 26 December 1991.

So the end of the Cold War involved changing relations between the superpowers, the loss of communist control in Eastern Europe and the break-up of the USSR. It was not one battle or one day.

August 1991
Failed hardline coup against Gorbachev.
Boris Yeltsin
Leader of Russia who resisted the coup.
26 December 1991
The USSR formally ends.

Worked example: A trigger inside a bigger story

Was the August coup enough on its own to explain the Soviet collapse?

  1. Long-term: economic crisis and republics seeking self-rule.
  2. Trigger: the failed coup shows Gorbachev cannot control his own leaders.
  3. Result: Yeltsin gains power, republics leave, and the USSR ends in December.

Watch out for this

Because the coup failed, Gorbachev got his power back.

The coup's failure made Yeltsin stronger, not Gorbachev. The USSR ended four months later.

Check your understanding

Who gained most authority from the failed coup of August 1991?

  1. The hardliners, who kept power in Moscow.
  2. Boris Yeltsin, who publicly resisted it.
  3. Gorbachev, who returned with full control.
Show the answer

Boris Yeltsin, who publicly resisted it.

Yes. Yeltsin's stand made him stronger than Gorbachev.
