Since the end of the last century, gender and women's rights have become common and increasingly familiar topics to common sense. This happens due to the effect of many social and political changes, and thanks to the strength of feminisms, whose critical proposals sediment in a radical cultural and epistemological transformation. They gain more and more recognition in terms of rights, and also gain space, voice and relevance. Equality is a central concept of modern politics, inescapable when it comes to thinking about the law, and a core notion for the feminist movement. Through this principle, modern states dispense with social status to consider all their members as equals under their political orbit. The feminist movement emerges as an organization of women's actions around the declaration of equality as a guarantee of right. Thus, in the approach to feminist discussions about the law, equality appears as a central and unavoidable element, making the trinomial feminisms-law-equality an equilateral triangle. This research proposes a chronological and analytical journey of feminist incursions into law. The analysis and systematization proposed here are thus demarcated around the debates on equality and law in the area of ​​legal feminisms.
