General elections were held in Sweden between 4 and 17 September 1920,[1] the last before universal suffrage was introduced the following year.[2] The Social Democratic Party remained the largest party, winning 75 of the 230 seats in the Andra kammaren of the Riksdag.[3] Later in October 1920 Hjalmar Branting was succeeded as prime minister by Baron Louis De Geer.
