Civil rights movements are significant in modern politics because they have shaped societal norms and laws related to equality and justice. These movements raise awareness of systemic injustices and advocate for the rights of marginalized groups, thereby promoting a more equitable society. The impact extends to legislation, influencing policies on issues like discrimination, voting rights, and social welfare. Their legacy fosters continued activism and inspires future generations to challenge oppressive systems, further embedding civil rights into the fabric of democratic governance.
