Answer:
The year 1989 saw the official end of the Cold War, through the fall of the Berlin Wall.
Explanation:
The Cold War was a political, economic, social, military, informative and scientific confrontation initiated after the end of World War II between the Democratic Western bloc led by the United States, and the Communist Eastern bloc 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 (beginning of perestroika in 1985, nuclear accident of Chernobyl in 1986, fall of the Berlin wall in 1989 and failed coup in the USSR in 1991). Neither of the two blocks ever took direct actions against the other, which is why the conflict was called "cold war".
