The Representation of the People Act 1918 was an Act of Parliament passed to reform the electoral system in Great Britain and Ireland. It is sometimes known as the Fourth Reform Act. The Act extended the franchise in parliamentary elections, also known as the right to vote, to men aged over 21, whether or not they owned property, and to women aged over 30 who resided in the constituency whilst occupying land or premises with a rateable value above £5, or whose husbands did. At the same time, it extended the local government franchise to include women aged over 30 on the same terms as men. It came into effect at the 1918 general election.
As a result of the Act, the male electorate was extended by 5.2 million to 12.9 million. The female electorate was 8.5 million. The Act also created new electoral arrangements, including making residence in a specific constituency the basis of the right to vote, institutionalising the first-past-the-post method of election, and rejecting proportional representation, although this failed by only seven votes in the Commons during the Act's progress.
It was not until the Representation of the People (Equal Franchise) Act 1928 that women gained electoral equality. The 1928 Act gave the vote to all women aged over 21, regardless of any property qualification, which added another five million women to the electorate.
After the Third Reform Act in 1884, 60% of male householders over the age of 21 had the vote. This left 40% who did not – including the poorest in society. Thus millions of soldiers returning from World War I would still not have been entitled to vote in the long overdue general election. (The last election had been in December 1910. An election had been scheduled for 1915, but was postponed to a time after the war.)
The issue of a female right to vote first gathered momentum during the latter half of the nineteenth century. In 1865, the Kensington Society, a discussion group for middle-class women who were barred from higher education, met at the home of Indian scholar Charlotte Manning in Kensington.
