What political changes swept through Europe during the second half of the twentieth century?

2 answers

After World War II, Europe was devastated. Thanks to the U.S. and other allies, the countries quickly recovered their industries, flourished and were able to provide many services for their citizens. Many countries joined together to form the European Union, a powerful political entity that enforced fairly uniform conditions across the EU and is a major trader in the world market, partly because of the Euro dollar.
With the fall of communism and the Soviet Union, several new countries were formed -- Slovenia, Serbia, Croatia, Macedonia, Czech Republic, and Slovakia -- among others.
