In 1913 the Icelandic parliament granted women the right to vote. Suffrage was no longer based on income anymore. This was ratified as a law by the Danish king on June 19th 1915. There were limitations; women had to be aged 40. These age limitations were lifted in 1920.
Seeing women in Iceland win the vote in 1915, at a time when the Great War was already changing attitude towards the role of women in Britain, women in Britain were encouraged to believe they would soon win the right to vote also.
