leader of the Third Reich, leader of the Nazi Party, and author of "Mein Kampf." Throughout the 1930s, he violated the Treaty of Versailles, imposed restrictions on German Jews, and initiated World War II in September 1939, when he invaded Poland. At first Germany was very successful in the war, but after betraying the USSR, Germany soon was forced to retreat back to Germany. Meanwhile, the Holocaust was underway, and thousands were dying daily. Hitler was also the target of few assassination plots during the war. As the war neared its end, Hitler committed suicide in Berlin, Germany on April 30, 1945, as Allied troops approached Berlin.
