Federal elections were held in Switzerland on 28 October 1917. The Free Democratic Party retained its majority in the National Council.^[1] They were the last elections held under the majoritarian system; following a referendum in 1918 in which two-thirds of voters voted for the introduction of proportional representation, the electoral system was changed and early elections held in 1919.

Electoral system[edit]

The 189 members of the National Council were elected in 49 single- and multi-member constituencies using a three-round system. Candidates had to receive a majority in the first or second round to be elected; if it went to a third round, only a plurality was required. Voters could cast as many votes as there were seats in their constituency.^[2] There was one seat for every 20,000 citizens, with seats allocated to cantons in proportion to their population.^[2]

Results[edit]

Voter turnout was highest in Schaffhausen (where voting was compulsory) at 86.8% and lowest in Uri at 23.4%.
