German politician, leader of the left wing of the Roman Catholic Centre Party in Germany and signatory of the Armistice of World War I.
Erzberger turned from teaching school to journalism with the Centre newspaper, Deutsches Volksblatt, and worked his way up in the Centre Party in Württemberg. He became a member of the Reichstag in 1903 and gradually established himself as the leader of the party’s left wing. His sensational attack on Bernhard von Bülow’s government over conditions in Germany’s African colonies forced the dissolution of the Reichstag in December 1906. During World War I, although Erzberger at first favoured extensive annexations by Germany, he was decisively involved in the Reichstag resolution of 19 July 1917, proposing a negotiated peace with no territorial gains, and also in the events leading to the resignation of Chancellor Theobald von Bethmann Hollweg, whom he wanted replaced by Bülow. As leader of the new Reichstag majority he aimed at democratic constitutional reform for Germany. While approving the Treaty of Brest-Litovsk (1918), Erzberger demanded opportunities for self-determination for eastern Europeans. Erzberger headed the German deputation to the Truce Commission of Compiègne, Fr., where, on November 11, he signed the Armistice.
He served under Philipp Scheidemann in Germany’s first republican government and vigorously pressed for acceptance of the Versailles Treaty. From June 1919 to March 1920 he was vice chancellor and finance minister under Gustav Bauer. His fiscal reforms were opposed both by the former propertied classes and by the federalists, who regarded them as steps toward a unitary state.
As a signatory of the Armistice and a protagonist of the republican-democratic system, Erzberger became the victim of a slander campaign from the extreme right. In March 1920 he was successful in a lawsuit against Karl Helfferich, who accused him of political corruption. Receiving only paltry damages, however, Erzberger resigned his ministry. The Centre failed to provide Erzberger with adequate support during these attacks upon him, and after his resignation he was neglected by the party. While on holiday in the Black Forest, he was shot dead by members of a nationalist organization on 26 August 1921.
