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.
State Council of East Germany
When the German Democratic Republic was founded in 1949, its constitution in its formal structure resembled a bourgeois, federalist democratic system in order to portray the GDR as the legitimate continuation of the prewar Weimar Republic in opposition to the separatist Federal Republic. One of the "bourgeois" features of the constitution (in Article 66) was the office of President, which was filled by Wilhelm Pieck, formerly the leader of the eastern branch of the Communist Party of Germany and now one of the two chairmen of the Socialist Unity Party.
