1944 Icelandic constitutional referendum

A constitutional referendum was held in Iceland between 20 and 23 May 1944. The 1 December 1918 Danish–Icelandic Act of Union declared Iceland to be a sovereign state separate from Denmark, but maintained the two countries in a personal union, with the King of Denmark also being the King of Iceland. In the two-part referendum, voters were asked whether the Union with Denmark should be abolished, and whether to adopt a new republican constitution. Both measures were approved, each with more than 98% in favour. Voter turnout was 98.4% overall, and 100% in two constituencies, Seyðisfirði and Vestur-Skaftafjellssýsla.
