ドイツ労働者党
Following Germany's defeat in World War I, hyperinflation, mass unemployment, poverty, crime and civil unrest plagued the country. During that time, Heiden served in a "Freikorps" unit. Also in 1919, a small right-wing political party known as the German Workers' Party (DAP) was created and seated in Munich. In 1920, it changed its name to the National Socialist German Workers' Party (Nazi Party; NSDAP). It rejected the terms of the Treaty of Versailles and advocated antisemitism and anti-Bolshevism.
