Post–Cold War era
The post–Cold War era is a period of history that has been ongoing since the dissolution of the Soviet Union, which began in 1988 and marked the end of the Cold War by 1991, thereby leaving the United States as the world's sole superpower. At the same time, Europe experienced the collapse of communism and was consequently freed from the "Iron Curtain" between the American-aligned Western Bloc and the Soviet-aligned Eastern Bloc, which gradually embraced market economies.
