1918 Swiss referendums

Two referendums were held in Switzerland during 1918.^[1] The first was held on 2 June on introducing a direct federal tax, and was rejected by a majority of voters and cantons.^[1] The second was held on 13 October 1918 on introducing proportional representation for National Council elections, and was approved by a majority of voters and cantons.^[1] As a result, proportional representation was introduced in the 1919 elections.^[2]

Background

Both referendums were popular initiatives,^[1] which required a double majority; a majority of the popular vote and majority of the cantons.^[3] The decision of each canton was based on the vote in that canton.^[3] Full cantons counted as one vote, whilst half cantons counted as half.^[3]
