This book reflects on the centennial of women's suffrage in the Nordic region and beyond, by exploring its relevance to political gender equality today and the conditions for feminist institutional change. The book brings together historians and political scientists to provide a long-term historical perspective that lays the groundwork for theoretical development. In this regard, the book makes two key contributions: it furthers our understanding of different types of gendered institutional constraints on women's political inclusion and elaborates feminist institutional strategies to counter these constraints.
