This essay offers a conceptualization of a comparative politics of gender (CPG) and some explanations for why CPG work is marginalized in the comparative politics subfield. I delineate CPG as a field of study in which gendered dependent or independent variables are the defining feature and present illustrative examples of four different types of CPG research. I contend that institutional and historical factors account for much of the marginalization of CPG research, and I propose some courses of actions through which CPG scholars can lessen this marginalization. The failure of comparative politics scholars to engage with gendered work is also a serious problem. The essay concludes by offering some suggestions for better integrating CPG scholarship into the subfield.
