Policy reformers often make bold promises to improve government responsiveness to citizen demands. Yet such proclaimed openings from above often fall short, get diverted, or are blocked. This study uses the state-society synergy approach to analyze exceptional cases when reformers within the state managed to deliver openings for citizen action that tangibly empowered otherwise excluded or marginalized groups. What happens when these reform strategies are attempted? We used process tracing, combined with qualitative comparative analysis, to identify patterns across 19 cases in the global South where state actors created a more enabling environment for citizens’ collective action.
