The Nazi Party.

Under the leadership of Adolf Hitler (1889-1945), the National Socialist German Workers' Party, or Nazi Party, grew into a mass movement and ruled Germany through totalitarian means from 1933 to 1945.

Founded in 1919 as the German Workers' Party, the group promoted German pride and anti-Semitism, and expressed dissatisfaction with the terms of the Treaty of Versailles, the 1919 peace settlement that ended World War I (1914-1918) and required Germany to make numerous concessions and reparations.

Hitler joined the party the year it was founded and became its leader in 1921. In 1933, he became chancellor of Germany and his Nazi government soon assumed dictatorial powers.

After Germany's defeat in World War II (1939-45), the Nazi Party was outlawed and many of its top officials were convicted of war crimes related to the murder of some 6 million European Jews during the Nazis' reign.

Sales of Hitler's political autobiography "Mein Kampf," sometimes referred to as the bible of the Nazi Party, made him a millionaire. From 1933 to 1945, free copies were given to every newlywed German couple. After World War II, the publication of "Mein Kampf" in Germany became illegal.
