This article by Rosemary Auchmuty and Erika Rackley introduces the Women's Legal Landmarks Project. The project is an interdisciplinary collaboration involving feminist scholars from law and other disciplines engaging in the process of identifying, researching and producing critical accounts of the key legal events, cases and statutes which represent significant turning points for women in the UK and Ireland. In creating the first scholarly anthology of legal landmarks for women spanning four jurisdictions and spanning eleven centuries, it seeks to contribute both to the development of the discipline of feminist legal history as well as societal understandings of the contribution women have made to public life and, more specifically, their involvement in the production of law, law reform and justice.
