United Nations Resolution 1325 affirmed the UN’s commitment to including women in peacekeeping missions. Some scholarly work has examined the impact of increased women’s activity on mission effectiveness, but this work has largely been limited to case studies or theoretical arguments. Even so, this work does suggest that missions with more women may be better able to interact with local populations, improve public attitudes towards missions, and help maintain greater internal accountability. Women police might be especially important as they would be able to gather more effective intelligence. I predict these factors would also make those missions more effective in supporting their peacekeeping mandates. To test this hypothesis, I use cross-national data from post-civil war African countries between 2000 and 2017 in which the UN deployed a peacekeeping mission with a civilian protection mandate. I specifically examine whether missions with more women serving as troops and police translate into a reduction in violence against civilians.
