Feminist mobilization, crucial for advancing women's human rights, has increased in all world regions since 1975. However, we do not know enough about the global impact of this mobilization because we lack adequate databases to explore the ways that feminist mobilization interacts with other factors that enhance and limit women's rights, such as democracy, intergovernmental processes, and transnational, regional organizing. Our ability to explore these questions is obstructed by a lack of data on the global south and measures that focus on formal organizations. This project remedies these gaps, developing an improved measure of feminist mobilization that encompasses autonomous, domestic feminist mobilization in 126 countries, 1975–2015, enabling us to track global and regional trends. Using regional comparisons and statistical analysis, we use this new measure to reveal new patterns and complexities in feminist mobilization. We discern distinct regional patterns in such organizing that defy facile predictions of global convergence and suggest a central role for UN processes advancing women's rights. Our analysis also points to the importance of transnational feminist networks and democratization as factors enabling and strengthening feminist mobilization. We conclude by suggesting some fruitful avenues for exploring relationships between feminist movements, international institutions, and democracy.
