Adolf Hitler (German pronunciation: [ˈadɔlf ˈhɪtlɐ]) 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, after 1934, also head of state as Führer und Reichskanzler, ruling the country as an absolute dictator.
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 race"; 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. ([Source.][1])
