Well, there's actually MORE than one countries in Europe that became communist in the post WWII era. Here they are:
because the communist and germanys country lost power
Communism means a classless stateless society based on production for use. Clearly no country became Communist after WW1, and Communism will have to exist at a global level anyway. Russia became state capitalist.
The U.S.
No part of Europe was ‘under Communist rule’. Communism is a classless stateless society based on production for use, and that clearly did not exist anywhere in Europe.
North Korea became communist and South Korea became democratic
Czechoslovakia
Russia. They became communist during Lenin's reign.
the league of nations was established.

During World War II, the primary communist country was the Soviet Union, which played a significant role in the Allied powers' efforts against the Axis. Additionally, other countries had communist movements or parties, but they were not fully communist states at the time. Notably, China had a significant communist faction, the Chinese Communist Party, led by Mao Zedong, although it was not in control of the entire country until after the war. Other regions, like Eastern Europe, had communist parties that gained prominence during the war, but they became dominant only post-war.
The Soviet Union.The Soviet Union, under Joseph Stalin, considered itself to be the world's leader of Communism, since they had the world's first and only Communist country (which is a bit of a contradiction, but that's a story for another time).As the Soviets liberated countries in Eastern Europe, they tended to work with local Communist parties in those countries, and then would install their leaders as the new rulers of the country. With a new Communist government in control, the Soviet Union would then control that government, and thus, that country.
