The EndSARS protest of October 2020 represents one of the most significant episodes of youth-led civic mobilisation in Nigeria's recent democratic history, emerging from widespread grievances over police brutality and broader concerns about governance and institutional accountability. Despite the immediate achievement of the dissolution of the Special Anti-Robbery Squad (SARS), the protest generated substantial political, economic, social, security, and administrative consequences, raising questions about the responsiveness of the Nigerian government to citizens' grievances. This study examines the implications of the EndSARS protest for the Nigerian government, focusing particularly on its economic, political, social, and administrative effects, the government's response, and the prospects for alternative citizen-government engagement mechanisms. The study is anchored on Structural Functionalist Theory, which explains social protest as a manifestation of dysfunction within interconnected institutional structures and a demand for institutional adjustment. An exploratory research design was adopted, relying exclusively on secondary sources obtained from academic literature, institutional reports, newspaper publications, and credible online materials. Data were analysed qualitatively through content analysis. Findings indicate that EndSARS compelled the government to dissolve SARS, heightened demands for police accountability, strengthened youth political participation and stimulated institutional mechanisms such as Judicial Panels of Inquiry. However, the protest and its violent aftermath also disrupted economic activities, destroyed public and private assets, weakened social order and imposed high administrative and security costs. The study concludes that unresolved institutional grievances can escalate into disruptive collective action. It recommends stronger police accountability, institutionalised grievance resolution mechanisms, structured youth engagement, rights-based protest management, and responsive digital governance.
