Communism continued in existence long after the concept of the Iron Curtain was established.
A dictator might have been a good person at first. When a leader is in power for a really long time his mentality changes, thus creating a dictator. Two things create a dictator, being in power for too long and unlimited powers, as in absolute monarchy where the leader has right to do anything.
long march
The two Russian Revolutions in 1917 left the Bolsheviks ('majority') in power in Russia. The end of Russian communism is debatable. The communist ideology was losing favor and losing economically by 1989. The official end of the Communist Party rule was 1991. Many communist-style structures have continued in place long after the end of communism.
Vietnam not long ago had to be freed of communism from america. They've realized how to trick your mind into giving ultimate power to dictators, etc. It seems like a good idea at first but starts to crumble when people break the rules.
1917 to 1991
