Adolf Hitler (German pronunciation: ; 20 April 1889 – 30 April 1945) was an Austrian-born German politician and the leader of the National Socialist German Workers Party (German: Nationalsozialistische Deutsche Arbeiterpartei, abbreviated NSDAP), commonly known as the Nazi Party. He was Chancellor of Germany from 1933 to 1945, and served as head of state as Führer und Reichskanzler from 1934 to 1945. Hitler is most remembered for his central leadership role in the rise of fascism in Europe, World War II and the Holocaust.
A decorated veteran of World War I, Hitler joined the precursor of the Nazi Party (DAP) in 1919, and became leader of NSDAP in 1921. He attempted a failed coup d'etat known as the Beer Hall Putsch, which occurred at the Bürgerbräukeller beer hall in Munich on November 8–9, 1923. Hitler was imprisoned for one year due to the failed coup, and wrote his memoir, "My Struggle" (in German Mein Kampf), while imprisoned. After his release on December 20, 1924, he gained support by promoting Pan-Germanism, anti-semitism, anti-capitalism, and anti-communism with charismatic oratory and propaganda. He was appointed chancellor on January 30, 1933, and transformed the Weimar Republic into the Third Reich, a single-party dictatorship based on the totalitarian and autocratic ideology of Nazism.
Hitler ultimately wanted to establish a New Order of absolute Nazi German hegemony in continental Europe. To achieve this, he pursued a foreign policy with the declared goal of seizing Lebensraum ("living space") for the Aryan people; directing the resources of the state towards this goal. This included the rearmament of Germany, which culminated in 1939 when the Wehrmacht invaded Poland. In response, the United Kingdom and France declared war against Germany, leading to the outbreak of World War II in Europe.
