Specials for United Artists The Rise and Fall of American Communism - 1964 TV was released on: USA: 21 February 1964
No one believed the rise of communism was a greater threat than Germany during WWII. Western Europe was allied with communist Russia during WWII, so they did not wish to destroy their ally. It wasn't until after WWII that fear shifted to the rise of communism, as communism spread all over Eastern Europe and even divided Germany.
Charlemagne was the first emperor in Europe after the fall of the Roman Empire. He united most of Western Europe, also for the first time after the fall of the Roman Empire. He is known as 'the Father of Europe'. Before his rise to power, Europe was obviously divided.
demand will rise
Communism didn't rise in Europe until the end of WWI (1917 for Russia, the war ended in 1918); so that eliminates WWI. So WWII in Europe (ETO-European Theater of Operations) has to be it. Since there's been no major wars in Europe since 1945 (WWII).
Prior to the fall of the Romanovs and the rise of Communism, Russians were predominantly Russian Orthodox Catholics (as compared to Greek Orthodox or Roman Catholicism).
Certainly the Nazi Party & Hitler's popularity grew in Germany, based on National Reichstag (Parliament) Elections from 1928 to 1932. However, Communism did not "rise" in Eastern Europe & East Germany after World War Two. It was imposed by brutal force by Stalin's Soviet Union when his nation occupied Eastern Europe when Hitler was defeated. Both the Nazis & Communists were evil totalitarian tyrants, however in Germany the Nazis were elected into power after being fooled by Nazi propaganda. In Eastern Europe those people did not want communism, and tried to resist.
It does not rise or fall. It is an imaginary line.
It was established on november 7,1930.
