Philipp Scheidemann, German journalist and politician, 10th Chancellor of Germany (died 1939)

Philipp Heinrich Scheidemann was a German politician of the Social Democratic Party of Germany (SPD). In the first quarter of the 20th century he played a leading role in both his party and in the young Weimar Republic. During the German Revolution of 1918–1919 that broke out after Germany's defeat in World War I, Scheidemann proclaimed a German Republic from a balcony of the Reichstag building. In 1919 he was elected Reich Minister President by the National Assembly meeting in Weimar to write a constitution for the republic. He resigned the office the same year due to a lack of unanimity in the cabinet on whether or not to accept the terms of the Treaty of Versailles.

The chancellor of Germany, officially the federal chancellor of the Federal Republic of Germany, is the head of the federal government of Germany. The chancellor is the chief executive of the Federal Cabinet and heads the executive branch. The chancellor is elected by the Bundestag on the proposal of the federal president and without debate. During a state of defence declared by the Bundestag the chancellor also assumes the position of commander-in-chief of the Bundeswehr.
