Hitler was of great historical importance—a term that does not imply a positive judgment—because his actions changed the course of the world. He was responsible for starting World War II, which resulted in the deaths of more than 50 million people. It also led to the extension of the Soviet Union’s power in eastern, central, and Balkan Europe, enabled a communist movement to eventually achieve control in China, and marked the decisive shift of power away from western Europe and toward the United States and the Soviet Union. In addition, Hitler was responsible for the Holocaust, the state-sponsored killing of six million Jews and millions of others.

Hitler’s rise to power traces to 1919, when he joined the German Workers’ Party that became the Nazi Party. With his oratorical skills and use of propaganda, he soon became its leader. Hitler gained popularity nationwide by exploiting unrest during the Great Depression, and in 1932 he placed second in the presidential race. Hitler’s various maneuvers resulted in the winner, Paul von Hindenburg, appointing him chancellor in January 1933. The following month the Reichstag fire occurred, and it provided an excuse for a decree overriding all guarantees of freedom. Then on March 23 the Enabling Act was passed, giving full powers to Hitler. When Hindenburg died on August 2, 1934, the chancellorship and the presidency were merged, and Hitler secured his position as Führer (“leader”).

Hitler had an overriding ambition for territorial expansion, which was largely driven by his desire to reunify the German peoples and his pursuit of Lebensraum, “living space” that would enable Germans to become economically self-sufficient and militarily secure. Such goals were greeted with support by many within Germany who resented the harsh terms of the Treaty of Versailles, which had ended World War I. Through various means he was able to annex Austria and Czechoslovakia with little resistance in 1938–39. Then on September 1, 1939, Germany invaded Poland, which had been guaranteed French and British military support should such an event occur. Two days later both countries declared war on Germany, launching World War II.

A key figure of Hitler’s inner circle was Joseph Goebbels, minister of propaganda and a fervent follower whom Hitler selected to succeed him as chancellor. However, Goebbels only held the post for one day before committing suicide. Also notable were Hermann Göring, who was a leader of the Nazi Party and one of the primary architects of the Nazi police state in Germany; Heinrich Himmler, who was second in power to Hitler; Joachim von Ribbentrop, foreign minister and chief negotiator of various treaties; Martin Bormann, who was one of Hitler’s closest lieutenants; and Walther Funk, an economist who served as president of the Reichsbank.

As Soviet troops entered the heart of Berlin, Hitler committed suicide on April 30, 1945, in his underground bunker. Although there is some speculation about the manner of his death, it is widely believed that he shot himself. Eva Braun, whom he had recently married, also took her own life. According to his wishes, both bodies were burned and buried. Almost immediately, however, conspiracy theories began. The Soviets initially claimed that they were unable to confirm Hitler’s death and later spread rumors that he was alive. According to subsequent reports, however, the Soviets recovered his burnt remains, which were identified through dental records. Hitler’s body was secretly buried before being exhumed and cremated, with the ashes scattered in 1970.
