What did Europe do during the cold war?

All the Eastern European countries were under controll of the Soviet Union during the Cold War. These countries included Poland, Lithuania, Romania, Bulgaria and even part of Germany, plus a few other countries. Germany was split into two sections after WW2. The eastern half belonged to Russia while the western half was controlled by Great Britain, America and France. Yugoslavia, while controlled by the Soviets, was not greatly affected by Russian influence. Their leader Tito at the time, was very hesitant to be controlled by the USSR.

Who is the person that started war world 2?

The primary person involved in starting World War 2 in Europe was Adolf Hitler. Very few wars are really started by one person, but Hitler has almost exclusive ownership of the start of World War 2 in Europe. The Asian half of World War 2 can't be blamed on a single person as much as it can be pinned on the culture of the leading Japanese people of the time. The xenophobic, imperialistic, expansive, and self-righteous leadership led the country into a horrifying war that consumed tens of millions of lives.

Why did Hitler want to rule the world?

He actually didn't want to. All he wanted was "Lebensraum" for the German people to live, which included the Soviet Union, Poland, and most of Eastern Europe. Its a common misconception that he wanted to rule the world.
