Answer: Communist countries.
Step-by-step explanation:
In this case, what is characteristic is the fact that the countries of Eastern Europe were communist after the war. In that part of the world, the Soviet Union had a great influence, and therefore the spread of communism in that part of the world is evident. The Soviet Union put pressure on many countries to maintain communist ideals. By the 1990s, communism would gradually become extinct in that part of Europe, and countries would establish democracy. In some countries, the fall of communism passed quietly and without violence (such as Czechoslovakia), while in others, the fall of communism was accompanied by wars (Yugoslavia).
