What caused women's liberation?Watch this thread
The Sufragettes were essentially Victorian middle class radicals.
But it took World War 1 for women to show how they could help run a country in the absence of so many men and then they got the vote.
In the 1920 the flappers epitomised the feminine confidence. The Great Depression and World War 2 saw a shift to women being needed for work and morale. A golden age of the (suburban) housewife is regarded as the 1950s and the new goods that were available meant that some went back out to work in the 1960s.
Middle class feminists in the 1960s again strove, in ways that sometimes must have seemed a bit vulgar if not patronising to many working class women, to promote the women's cause. But consumerism meant that women did keep going out to work and rising house prices, cost of living, luxury items, divorce, single living, and simply because it is now the done thing mean that they still do.
