Civil rights movements significantly influence legislation by advocating for legal reforms and societal change. These movements raise awareness of systemic inequalities and mobilize public support for legislative action. Successful advocacy can lead to landmark laws, such as the Civil Rights Act and the Voting Rights Act in the United States, which address discrimination and promote equality. Additionally, they often serve as a catalyst for broader social justice initiatives, shaping public policy and ensuring that governments are held accountable to the principles of human rights.
