Martin J.’s *La Parité* examines the role of gender equality in contemporary political life. Drawing on case studies from French politics and broader European contexts, the work explores how women’s participation reshapes policy agendas, party dynamics, and public discourse. It investigates the historical barriers to female representation, the mechanisms of parity legislation, and the social implications of more balanced gender ratios in elected bodies. By linking theoretical perspectives on political activity with concrete examples of women in office, the book offers a nuanced analysis of the challenges and opportunities that arise when men and women share political power. Intended for scholars, students, and anyone interested in the intersection of gender and governance, the text provides both a critical framework and practical insights into advancing parity in democratic institutions.
