The German Nationalist Party (Deutsche Nationalpartei, DNP) was a political party in Germany that emerged in the late 19th century. It primarily represented the interests of the German middle class and promoted nationalism, advocating for a unified German state. The party was known for its conservative stance and opposition to socialism and liberalism. In the early 20th century, the DNP gained influence, particularly during the Weimar Republic. It sought to preserve traditional values and was critical of the Treaty of Versailles, which ended World War I. The party eventually merged with other nationalist groups, contributing to the rise of more extreme nationalist movements in Germany, including the Nazi Party.
