This article shows how a movement for gender parity in politics, distinct from the second-wave women's liberation movement, formed in the 1990s, and how the subsequent parity reforms, which public opinion strongly favoured, gained support among political elites. It highlights the triumph of a conception of democracy based on the idea that political representation is to be shared between two equal and different sexes. Nevertheless, what appears to be a common sense victory, namely, the establishment of a universalism finally made real by the increase in the number of women in elected assemblies, is in fact ambiguous, especially when considered in relation to the feminism of the 1970s.
