Approximately how long was the cold war period? a.) 1920s to 1940sb.) 1940s to 1980sc.) 1980s to 2000d.) 1920s to the present day

The correct answer is B. The Cold War period lasted from 1940s to 1980s.

Explanation:

Cold War was an ideological, political and military rivalry between the Eastern Bloc, formed by the USSR and its satellite states concentrated since 1955 in the Warsaw Pact and non-European countries allied with the USSR; and the Western bloc, that is, non-communist states concentrated since 1949 in NATO and parallel defense blocs (SEATO, CENTO) under the leadership of the United States, from 1947 to 1991. The Cold War was accompanied by an arms race of both military blocks. The conflict was initiated by the policy of the USSR seeking to expand the range of territorial expansion and its dominion zone, and by imposing by force the communist system on the countries of Central and Eastern Europe.

The Cold War lasted from 1947 - from the collapse of the anti-Hitler coalition and the establishment of an exclusive zone of influence of the USSR in Central Europe - until the collapse of communist systems in Europe (Autumn of Nations) in 1989 and the liquidation of the USSR itself in the second half of 1991. The collapse of the Eastern Bloc eliminated the bipolar system in international politics and ended the Cold War era.
