Hitler actively sought Lebensraum ("living space") for the German people. His aggressive foreign policy is considered to be the primary cause of the outbreak of World War II in Europe. He directed large-scale rearmament and on 1 September 1939 invaded Poland, resulting in British and French declarations of war on Germany. In June 1941, Hitler ordered an invasion of the Soviet Union. By the end of 1941 German forces and their European allies occupied most of Europe and North Africa. Failure to defeat the Soviets and the entry of the United States into the war forced Germany onto the defensive and it suffered a series of escalating defeats, partly because of Hitler's countless military blunders. In the final days of the war, during the Battle of Berlin in 1945, Hitler married his long-time lover, Eva Braun. On 30 April 1945, less than two days later, the two committed suicide to avoid capture by the Red Army, and their corpses were burned. Under Hitler's leadership and racially motivated ideology, the regime was responsible for the genocide of at least 5.5 million Jews, and millions of other victims whom he and his followers deemed racially inferior.
Hitler's father, Alois Hitler, Sr. (1837–1903), was the illegitimate child of Maria Anna Schicklgruber.[2] Because the baptismal register did not show the name of his father, Alois initially bore his mother's surname, Schicklgruber. In 1842, Johann Georg Hiedler married Alois's mother, Maria Anna. After she died in 1847 and Johann Georg Hiedler in 1856, Alois was brought up in the family of Hiedler's brother, Johann Nepomuk Hiedler.[3] In 1876, Alois was legitimated and the baptismal register changed by a priest to register Johann Georg Hiedler as Alois's father (recorded as Georg Hitler).[4][5] Alois then assumed the surname Hitler,[5] also spelled as Hiedler, Hüttler, or Huettler. The Hitler surname is probably based on "one who lives in a hut" (Standard German Hütte for hut) or on "shepherd" (Standard German hüten...
