Grassroots movements challenge existing power structures by mobilizing ordinary citizens to advocate for change from the bottom up. These movements often focus on social, economic, or political issues that resonate deeply at the community level, creating pressure for reform. By fostering civic engagement and building coalitions, grassroots initiatives can influence political narratives and push for policies that address systemic inequalities. Their effectiveness lies in their ability to inspire collective action and challenge established norms, ultimately reshaping the political landscape toward more equitable governance.
