The First World War provided the first opportunity for women to take on traditional male jobs so it isn't surprising that in 1918 women over 30 were given the same political rights as men. But this change was not just a result of war - women had been campaigning for decades to be given the right to vote.
The campaign - the basics
Votes for women was part of a gradual improvement in women's rights that had been going on throughout the 19th century. The movement also campaigned for the right to divorce a husband, the right to education, and the right to have a job such as a doctor. Many women, however, saw the vote as the vital achievement that would give them a say in the laws affecting their lives.
