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
The office of president is open to all Germans who are entitled to vote in Bundestag elections and have reached the age of 40, but no one may serve more than two consecutive five-year terms. As yet (2017), only four presidents (Heuss, Lübke, von Weizsäcker and Köhler) have been elected for a second term and only two of them (Heuss and von Weizsäcker) completed those terms, while Lübke and Köhler resigned during their second term. The president must not be a member of the federal government or of a legislature at either the federal or state level.
