Political movements challenge systemic injustices by advocating for change and raising awareness about social inequalities. These movements mobilize individuals around shared goals, promoting collective action to address issues like racism, gender inequality, and economic disparities. By amplifying marginalized voices and demanding policy reforms, movements can reshape public attitudes and influence legislative agendas. Historical examples demonstrate that sustained activism can lead to significant social and political transformations, making these movements critical in the ongoing struggle for justice and equity.
