Nonviolent resistance movements defended democratic values and institutions throughout the 20th century and into the 21st. However, the trend seems to have shifted. Over the past decade, authoritarian backsliding has occurred across the globe, and mass movements demanding democracy have been defeated in about 90% of cases since 2010.
The Nonviolent Action Lab is an innovation hub for research on advancing democracy worldwide through civil resistance. The Lab produces and disseminates up-to-date knowledge on nonviolent action, how it works, global trends in success and failure, trends in political violence and state repression, and analysis of these trends.
