The Nazi, or National Socialist party, were led by Adolph Hitler. The Nazis believed that Germans were superior to all other people and blamed the worlds problems on people from minority groups including those from the Jewish religion as well as the Roma, a nomadic European ethnic group. Hitler and the Nazi‘s wished to increase German power. They invaded neighboring countries, such as Poland to take territory. In response, Britain and France declared war on Germany, and soon World War II raged in Europe.
