A decorated veteran of World War I, Hitler joined the German Workers' Party, precursor of the Nazi Party, in 1919, and became leader of the NSDAP in 1921. In 1923 Hitler attempted a coup d'état, known as the Beer Hall Putsch, at the Bürgerbräukeller beer hall in Munich. The failed coup resulted in Hitler's imprisonment, during which time he wrote his memoir, Mein Kampf (My Struggle). After his release in 1924, Hitler gained support by promoting Pan-Germanism, antisemitism, and anti-communism with charismatic oratory and propaganda. He was appointed chancellor in 1933 and transformed theWeimar Republic into the Third Reich, a single-party dictatorship based on the totalitarian and autocratic ideology of Nazism.
Hitler's avowed aim was to establish a New Order of absolute Nazi German hegemony in continental Europe. His foreign and domestic policies had the goal of seizing Lebensraum (living space) for the Germanic people. He oversaw the rearmament of Germany and the invasion of Poland by the Wehrmacht in September 1939, which led to the outbreak of World War II in Europe.[2]
Under Hitler's direction, in 1941 German forces and their European allies occupied most of Europe and North Africa. These gains were gradually reversed after 1941, and in 1945 the Allied armies defeated the German army. Hitler's racially motivated policies resulted in the deaths of as many as 17 million people,[3] including an estimated six million Jews and between 500,000 and 1,500,000 Roma
