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.
President of Germany
Germany has a parliamentary system of government in which the chancellor is the nation's leading political figure and "de facto" chief executive. The president has a mainly ceremonial role, but he can give direction to general political and societal debates and has some important "reserve powers" in case of political instability (such as those provided for by Article 81 of the Basic Law). The German presidents have wide discretion about how they exercise their official duties.
