Soviet control spread across Eastern Europe after WWII

Communist governments across Eastern Europe fell in 1989

In 1989, a series of mostly peaceful uprisings led to the collapse of communist regimes in Eastern Europe. Protests and political shifts in countries like Poland, East Germany and Czechoslovakia marked the end of Soviet dominance in the region.

During the Cold War, the rules-based order was largely limited to the West

The Soviet Union and its allies operated outside the Bretton Woods institutions, meaning the postwar liberal order functioned as a regional rather than a truly global system. This changed with the USSR's collapse in 1991.

The 1955 Warsaw Pact was the Soviet Union’s answer to NATO

The pact included Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Romania, and the USSR. The pact established collective security and a joint military command between the member countries.

The Soviet Union explained

Stalin transformed the USSR through rapid industrialization and brutal repression

The Soviet Union had a similar sphere of influence policy during the Cold War—the Brezhnev Doctrine

Articulated in 1968, the Brezhnev Doctrine claimed the Soviet Union's right to intervene militarily in its satellite states to prevent any deviation from communist rule. It was used to justify the invasion of Czechoslovakia that same year and the invasion of Afghanistan in 1979.

Economic stagnation and the arms race pushed the USSR toward collapse

The Soviet Union collapsed in 1991, due to economic decline and political unrest

By the late 1980s, the Soviet economy was stagnating and its political system was under tremendous strain. Soviet reforms failed to reverse the decline, and growing independence movements led to the USSR’s formal dissolution in 1991.

Gorbachev’s reform efforts accelerated the Soviet Union’s collapse

In the 1980s, Mikhail Gorbachev introduced glasnost (openness) and perestroika (restructuring) to reform the USSR. Instead of saving the system, the policies exposed deep problems—fueling unrest and weakening central control.

During the Cold War, the Soviet Union created a Eurovision competitor

The Soviet Union was not a member of the European Broadcasting Union, so it couldn't compete in Eurovision.

The competition was open to countries from across the globe, regardless of their form of government, though most entrants were from communist countries.

After more than seven decades of Soviet communism, the collapse of the system in the early 1990s opened a path for organized crime to take over the country's newly-privatized industries.
