What countries in Europe did Hitler take over?

At the height of its military conquests, Nazi Germany and the Axis powers occupied Europe from France to western Russia. They also occupied Norway, north Africa, and numerous islands in the Mediterranean Sea.

Nazi Germany's victories were short lived though. With insufficient manpower and equipment to adequately secure such an enormous territory, many patriots within conquered lands quickly formed guerrilla resistance movements to sabotage and harass the Nazi war effort.

Nazi Germany was militarily overextended, under-supplied, and ultimately outclassed by America, Russia, and Britain's massive military response. Nazi Germany was finally overwhelmed by superior numbers of Allied men and equipment attacking on three major fronts. The war ended in May 1945.
