The presence of gender provisions in peace agreements affects women’s participation in post-conflict societies as well as the chances that a post-conflict society will move towards gender equality. While there is an overall upward trend in the number of references to women’s rights and gender equality in peace agreements, gender-sensitive agreements are not a given. Why and how are peace agreements with gender provisions adopted? We use statistical analysis to explain why some peace agreements adopt gender provisions while others have no such provisions. Based on an analysis of 98 peace agreements across 55 countries between 2000 and 2016, we find that peace agreements are significantly more likely to have gender provisions when women participate in elite peace processes. Our study also shows that the likelihood of achieving a peace agreement with gender provisions increases when women’s representation in national parliaments increases and when women’s civil society participation is significant.
