Despite the promises made by Stalin at the Yalta Conference to allow free elections, he had in fact started turning Eastern Europe into a buffer zone between the Soviet Union and Western Europe
In the 1945 elections, a communist-led coalition (made up of more than one political party) government was elected. The Communists gradually removed their coalition partners and abolished the Romanian monarchy
Fearing that a non-communist government would be elected in 1947, Stalin invited 16 non-communist politicians to Moscow, where they were arrested. With their political opponents removed, the Polish communists won the election
Although non-communists won the 1945 election, a communist politician, Rakosi, took control of the secret police and used it to arrest and execute his political opponents. By 1948 the Communist Party was in complete control of the country
Czechoslovakia was the last country in Eastern Europe to fully fall to communism in 1948. At elections that year only communists were allowed to stand and a communist government was duly elected
