20 years ago, in 1993, Joni Lovenduski and Pippa Norris published their seminal edited book, Gender and Party Politics. Since this publication, a burgeoning of study of women and politics has come into being. Although this scholarship recognized the key importance of political parties in understanding women’s political participation and representation, the foci of many studies since has been on legislatures, parliamentary representation, policy-making and policy implementation.  Party politics and parties qua parties remain in comparison understudied by gender and politics scholars. Furthermore, the comparative parties scholarship is not yet a site for much gender and politics research. This roundtable brings together leading scholars of gender and politics to take stock of existing insights on party politics by gender and politics and comparative parties’ scholarship; identify and reflect on gaps in both literatures; and informed by this, set out a future theoretical and empirical research agenda. The roundtable thus speaks to gender and politics scholars as well as to party politics experts. It is part of a broader project on political parties that also include Miki Caul Kittilson (Arizona State University) and Pippa Norris (Harvard University), with the medium term aim of producing a new edited book on gender and party politics.
