In this article, we contend that the current gender and conflict literature ignores the context of military decisions and thus underestimates the support of women for certain types of military interventions. We argue that the issues related to humanitarian crises are likely to provoke support from women. Consequently, as more women enter elected positions in state legislatures, the more likely a state will become involved in a humanitarian military intervention. To test our argument, we compile a data set of humanitarian military interventions and women legislators from 1946 to 2003. A series of estimation approaches and robustness tests support our assertion that more women legislators impact the likelihood that a state will become involved in a humanitarian military intervention.
