Why was communist governments were established in most nations of eastern europe shortly after world war ii

Many of the Eastern European countries were liberated from the Nazis by Russia. They suffered a great deal under the Nazi occupation and they were afraid of a recurrence so for them communism was a safer option. Russia on the other hand, wanted to expand its power all over Eastern Europe so once they liberated a country, they did not leave. They used diplomacy andmilitary might to persuade these countries to embrace communism.
