Nazi Germany was a country in Europe from 1933 to 1945. It was led by a man named Adolf Hitler. Hitler was a very powerful leader who had a lot of followers. He wanted the country to be powerful, but he also wanted to get rid of people he didn't like. He and his followers, called Nazis, did bad things to Jews, disabled people, and others who were different. They put them in prison camps called concentration camps, where many people died. Nazi Germany was eventually defeated in 1945, after World War II.
