Most countries felt some effects from the Great Depression. Germany, still suffering after losing World War I, was hit very hard.
Adolf Hitler became popular by blaming Germany’s troubles on minority groups. He especially blamed Jews and Communists. In 1933, Hitler became dictator of Germany. He built up the German military with the goal of making his country a world power by conquering others.
In September 1939, Germany invaded Poland, starting World War II. The United States had pledged neutrality, meaning it wouldn’t take sides. But it was eventually drawn into it. War production, or making weapons and other materials for the military, finally brought the country out of the Great Depression.
