Political movements influence governance by mobilizing public support around specific issues, often leading to changes in laws and policies. These movements can bring attention to social injustices, environmental degradation, or economic inequalities, compelling policymakers to respond. For example, grassroots initiatives may push for reforms in areas such as civil rights, healthcare access, or environmental protections. As movements gain traction, they can reshape the political landscape, compel elected officials to align with constituent demands, and encourage broader participation in democratic processes, ultimately driving significant social and legislative change.
