Two years after the Representation of the People Act 1918, the Times published grave warnings against moves to extend voting rights to women under 30. Mature females might now engage with politics, but the “scantily clad, jazzing flapper to whom a dance, a new hat or a man with a car is of more importance than the fate of nations” must never be entrusted with a vote.

The fast, frivolous flapper of the 20s was partially a cultural stereotype, but she was also a focus of serious debate. With her short skirts and cigarettes, her cocktails, sexiness and sass, she was not only offensive to the men at the Times, but also a concern to older feminists, who saw in her pleasure-seeking, taboo-breaking ways a younger generation’s disregard of all for which the suffragettes had fought.

But if the politics of feminism seemed less important to the “flapper generation”, this was partly because young women were taking the struggle for freedom into their personal lives. Ideas of duty, sacrifice and the greater good had been debunked by the recent war; for this generation, morality resided in being true to one’s self, not to a cause. Towards the end of the decade, some feminists would argue that women’s great achievement in the 20s was learning to value their individuality.

Personal freedoms remained dependent on public reform and active UK feminists such as the Six Point Group continued to campaign. Women were given electoral equality with men in 1928; legislation brought equality in inheritance rights and unemployment benefits; and women profited from the Sex Discrimination (Removal) Act, which, in 1919, had given them access to professions such as law.

Changes in work patterns were dramatic, with a third of unmarried women moving into paid employment across an expanding range of jobs in medicine, education and industry. Mass employment also made women a consumer power. Fashion was one of several industries that expanded rapidly to meet their demands. While the Times considered clothes a frivolity, for women they were a daily marker of liberation: rising hemlines, sportswear and even trousers made their generation physically freer than any in modern history.

Sexual mores were also changing. While double standards persisted, a significant number of women were beginning to claim the same licence as men. There were small steps of encouragement, too, with divorce made easier by the Matrimonial Causes Act 1923 and contraception made more readily available by the Marie Stopes mail-order service. The flapper generation may have been comparatively apolitical and self-absorbed, but, as they puzzled out what freedom meant and tested their personal limits, they were broaching issues that would be hotly debated during the 60s and 70s.
