Georg Ledebour

Georg Ledebour was one of the strongest opponents of the SPD’s Burgfrieden policy. He publicly called for resistance against the Reich leadership’s war policy. Together with Hugo Haase and other leading left-wing members of the SPD, he initiated the 1917 breakaway of the USPD, which opposed the Kaiserreich’s foreign and war policy from then on. During the November Revolution, he boycotted the party’s cooperation with the SPD in the Council of People’s Representatives. As a USPD leader, he became a Member of the National Assembly in 1919, continuing on after that as a Member of the Reichstag. After a large majority of USPD members joined either the KPD or the SPD, he remained leader of the party up to 1923. Later on, he left the remains of the USPD and represented socialist splinter groups.
