The Cold War officially came to an end in the year 1991.

Explanation:

The Cold War was a political, economic, social, military, informative and scientific confrontation initiated after the end of the Second World War between the capitalist Western bloc led by the United States, and the Communist East block led by the Soviet Union.

Its origin is usually located between 1945 and 1947, during the tensions of the postwar period, and lasted until the dissolution of the Soviet Union with the failed coup in the USSR in 1991.

In 1991 the Soviet Union, which was the superpower of the socialist bloc, collapsed economically and territorially due to the Perestroika reforms carried out by Mikhail Gorbachev in view of the economic collapse of the Soviet Union, which consisted in quickly moving from an economy planned socialist to become a free-market economy similar to China, which was opposed by the most conservative part of the Communist Party. This rapid transition attempt provoked the dislocation of the entire industrial and agricultural fabric of the USSR, the country was virtually paralyzed, inflation soared and poverty increased and the ensuing social protests were channeled through nationalism, which led to the dissolution of the Soviet Union.
