The separation of Europe into Eastern and Western blocs emerged after World War II due to:
Western capitalist democracies (US-aligned) vs. Eastern socialist states (Soviet-aligned) with centralized economies and restricted political rights.
Physical and ideological border (Churchill, 1946) fortifying Eastern borders, restricting movement and communication.
Global US-USSR rivalry solidified division; NATO (West) vs. Warsaw Pact (East) military alliances.
Western growth and rising living standards contrasted with Eastern stagnation, shortages, and inefficient central planning.
Political repression in Eastern Bloc fueled internal dissent and Western criticism.
Collapse of USSR ended the division; Eastern transitions to democracy/market economies began. Fall of Berlin Wall (1989) was pivotal.
