The Nazi Party, officially known as the National Socialist German Workers' Party, was a far-right political party in Germany that rose to power in the early 20th century. Founded in 1920, it promoted extreme nationalism, anti-Semitism, and totalitarianism. Under the leadership of Adolf Hitler, the party gained significant influence, leading to the establishment of a dictatorship in 1933. The Nazi Party implemented policies that resulted in the persecution of various groups, most notably the Jewish people, and initiated World War II by invading Poland in 1939. The party's regime was marked by widespread propaganda, militarization, and the horrific consequences of the Holocaust, which led to the deaths of millions.
