Joseph Wirth (born Sept. 6, 1879, Freiburg im Breisgau, Ger.—died Jan. 3, 1956, Freiburg) was a liberal German statesman and chancellor during the Weimar Republic (1919–33), who advocated a policy of fulfillment of Germany’s obligations under the Versailles Treaty settlement and consistently opposed German militarism after both world wars.
Wirth, a member of the left wing of the Roman Catholic Centre Party, was elected to the Reichstag (federal lower house) in 1914 and served in the Weimar national assembly after the revolution of 1918. In 1920 he became minister of finance. After the Cabinet of Konstantin Fehrenbach resigned in protest over the heavy reparations obligations imposed by the Versailles Treaty, Wirth took office as chancellor in May 1921, pursuing a policy of treaty fulfillment. Although he resigned over the loss of much of Upper Silesia to Poland in October 1921, he formed a new Cabinet four days later. With his foreign minister, Walther Rathenau, he negotiated the Treaty of Rapallo with the Soviet Union (April 16, 1922), which broke Germany’s postwar isolation, but he then resigned over the reparations question in November 1922. He held a number of responsible posts toward the end of the Weimar period as minister for the provinces occupied by the Allies (1929–30) and minister of the interior in the Cabinet of Heinrich Brüning (1930–31). Retiring in October 1931, he was forced into exile after Adolf Hitler took power (January 1933). Wirth resided first in Paris and later in Switzerland. Returning home in 1948, he opposed West Germany’s rearmament and its membership in NATO, and he unsuccessfully called for a reunited, neutral Germany. These efforts gained him the Soviet Union’s Stalin Peace Prize for 1955.
