The Nazi Party, officially known as the National Socialist German Workers’ Party (NSDAP), was a far-right political movement in Germany led by Adolf Hitler from 1920 to 1945. It promoted ultranationalism, racial purity, and authoritarianism, ultimately leading to the establishment of a totalitarian regime responsible for World War II and the Holocaust, which caused the deaths of millions. The party was dissolved after Germany’s defeat in 1945.
