The Timeline of Contemporary period comprises the historical period closest to our times. It begins with the end of the Second World War in 1945 and goes up to the present day. But historians have focused mainly on the study of the Cold War years.

The bipolar world of the Cold War

The new system of international relations that emerged from World War II was based on a bipolar world. The United States of America and the Soviet Union were the two powers. They each formed their own system of alliances to ensure hegemony within their respective blocs.

The Western capitalist bloc was led by the United States. The main institutions were:

  • In the military field, the NATO (military alliance).
  • In the economic sphere, the IMF and the World Bank.

On the other hand, the Soviet or communist bloc was led by the Soviet Union. The Soviets established their own institutions:

The whole period was marked by uncertainty and fear of a new conflict on a global scale. The military scale and the permanent threat of nuclear war were present throughout this time.

Although the much feared Third World War never took place, the two powers were involved in military conflicts. The wars were peripheral, but they complicated international stability. Decolonization and independence movements were another destabilizing factor. These movements were used as an escape valve for the two superpowers. Through them they could intervene directly or indirectly without having to openly declare war.

In conclusion, the Cold War ended when the Soviet Union was unable to sustain the huge military expenditures. The economic crisis of the Soviet bloc became more acute in the 1970s and 1980s. The USSR, without money to keep the arms race open with the United States, collapsed. This happened in 1991.
