General elections were held in Sweden on 16 September 1956.[1][2] The Swedish Social Democratic Party remained the largest party, winning 106 of the 231 seats in the Second Chamber of the Riksdag.[3] A Social Democratic-Farmers' League coalition government was formed by Prime Minister Tage Erlander after the election with 125 of the total of 231 seats. Although the non-socialist parties held a majority in the Second Chamber, the Social Democrats held a majority in the First Chamber, so a non-socialist government could not be formed. The Social Democrats and the Farmers' League would later split due to disagreements over the pensions system in 1957, leading to the formation of Tage Erlander's third government and a snap election in 1958.
