Overview of the Cold War-
era:
The Cold War (1945-1991) was a geopolitical
rivalry between the U.S. and the Soviet Union,
driven by ideological differences. It featured an
arms race, the Space Race, and proxy wars. Key
events include the Cuban Missile Crisis, Berlin
Wall, and Afghan invasion. Détente eased
tensions briefly, but economic struggles and
internal dissent led to the Soviet Union's collapse
in 1991, marking the end of the Cold War and
reshaping global politics.
