Cold War Conflict and Consensus

1945–1965

The defeat of the Nazis and their allies in 1945 left Europe in ruins. In the immediate postwar years, as Europeans struggled to overcome the effects of rampant death and destruction, the victorious Allies worked to shape an effective peace accord. Disagreements between the Soviet Union and the Western allies emerged during this process and quickly led to an apparently endless Cold War between the two new superpowers — the United States and the Soviet Union. This conflict split much of Europe into a Soviet-aligned Communist bloc and a U.S.-aligned capitalist bloc and spurred military, economic, and technological competition.

Amid these tensions, battered western European countries fashioned a remarkable recovery, building strong democratic institutions and vibrant economies. In the Soviet Union and the “East Bloc” (the label applied to central and eastern European countries governed by Soviet-backed Communist regimes), Communist leaders repressed challenges to one-party rule but also offered limited reforms, leading to stability there as well. Yet the postwar period was by no means peaceful. Anti-Soviet uprisings in East Bloc countries led to military intervention and death and imprisonment for thousands. Colonial independence movements in the developing world sometimes erupted in violence, even after liberation was achieved. Cold War hostilities had an immense impact on the decolonization process, often to the detriment of formerly colonized peoples.

Cold War conflicts notwithstanding, the postwar decades witnessed the construction of a relatively stable social and political consensus in both Communist and capitalist Europe. At the same time, changing class structures, new migration patterns, and new roles for women and youths had a profound impact on European society, laying the groundwork for major transformations in the decades to come.
