Succeeding Prince Max von Baden as German Chancellor at War's end (Nov 1918 to Feb 1919), he then became President of the Weimar Republic from 1919 to 1925. The son of a master tailor, Ebert was a socialist and trade unionist who in 1905 became Secretary General of the German Social Democratic Party (SPD) and later became the SPD Party Chairman (1914). He was also an anti-revolutionary and even a monarchist. As was typical with Europe's other Socialist Party elites, he was a patriot whose nationalist feelings remained stronger than his internationalist convictions. Ebert lost two sons during World War One.
