Constitutional rights are significant in social movements as they provide a legal foundation for advocating change and challenging injustices. Movements often draw on constitutional provisions such as free speech and the right to assemble to legitimize their actions and rally support. By framing their struggles in terms of constitutional rights, activists can resonate with broader audiences and emphasize the legitimacy of their cause. Moreover, successful social movements can lead to legal reforms and reinforce the importance of protections enshrined in the Constitution, contributing to societal progress.
