Economic crisis, republican challenges and a failed hard-line coup destroyed the authority needed to hold the union together.
The USSR was a union of republics, including Russia, Ukraine and Belarus, governed under central Soviet authority in Moscow. Economic problems and national movements encouraged republic leaders to seek more control over their institutions and resources. Boris Yeltsin led the Russian republic and challenged Gorbachev, who led the whole Soviet Union. Russia and the USSR were therefore not interchangeable names. Change inside the union was not uniformly peaceful: violence in Lithuania and Latvia in early 1991 shows that Soviet non-intervention in Eastern Europe did not mean coercion had disappeared at home.
In August 1991, hard-line officials who wanted to halt reform attempted a coup, a seizure of power, against Gorbachev. The attempt failed, but his opponents in the central leadership had shown that he could not control them. Resistance, including Yeltsin's public stand against the coup, increased the authority of leaders outside Gorbachev's Soviet centre. The failure therefore weakened central communist power rather than simply restoring things as they had been. More republics then pursued independence.
In December, the leaders of Russia, Ukraine and Belarus declared that the USSR had ceased to exist and formed the Commonwealth of Independent States, an arrangement for cooperation between separate states rather than one Soviet government. Other republics joined. Gorbachev resigned on 25 December; the USSR formally ceased to exist on 26 December 1991. The Cold War's ending involved changing international relations, the loss of communist control in allied states and the Soviet breakup. It was not a single battle or one event on one day.
Worked example: Use a trigger inside a longer explanation
Was the August coup enough to explain the Soviet collapse?
- The failed coup accelerated the loss of central authority and strengthened rival leaders.
- Its impact depended on existing economic crisis, political division and demands for republican independence.
- Explain the interaction: the coup made an already weakened union harder to preserve, rather than creating every problem from nothing.
Watch out for this
Because the August coup failed, Gorbachev recovered the authority he had before it.
The failed attempt exposed divisions at the centre and strengthened Yeltsin and leaders seeking more power for their republics. Defeating the coup did not repair Gorbachev's damaged authority or the union's existing problems.
Check your understanding
Why could the failed August coup accelerate the USSR's breakup?
- Failure removed the economic and political disputes that had motivated the coup.
- The coup created demands for independence where there had previously been no challenges to Moscow.
- It discredited central authority and strengthened rival republic leaders in an already weakened union.
