This article analyzes the historical and political features of the development of women's political participation and its special importance in the incorporation into the constituent process in Chile, where for the first time in the world there will be a constituent body elected with parity. We will analyze and explain the social contract and the participation of women in decision-making (the development of women's political participation in the constitutional history of Chile); the incorporation of the quota law in 2015 as a precedent for parity; the difficulties that have had to overcome and the legal devices used to obtain a guaranteed quota in the future constituent body, to -finally- point out some central organic and programmatic axes that must be taken into account in the next constituent process to incorporate, thus, the gender perspective in the future constitutional text.
