President of Germany
Friedrich Ebert (SPD) served as Germany's first president, followed by Paul von Hindenburg. The office effectively came to an end upon Hindenburg's death in 1934 and its powers merged with those of chancellor. Adolf Hitler now ruled Germany as "Führer und Reichskanzler", combining his previous positions in party and government. The office, however, was not abolished and briefly revived at the end of the Second World War when Hitler appointed Grand Admiral Karl Dönitz as his successor as President of Germany. Dönitz agreed to the surrender to the Allies and was arrested a few days later.
Chancellor of Germany
When the Nazis came to power on 30 January 1933, the Weimar Constitution was "de facto" set aside. After the death of President Hindenburg in 1934, Adolf Hitler, the dictatorial party leader and chancellor, took over the powers of the president. The new official title became "Führer und Reichskanzler" (meaning "Leader and Chancellor of the Realm").
