Civil liberties protect citizens in political systems by guaranteeing fundamental rights and freedoms that safeguard individuals from government overreach and abuse. These liberties include freedoms of speech, assembly, religion, and the press, allowing citizens to express dissent, organize political movements, and participate in democratic processes without fear of reprisal. Civil liberties are essential for upholding a vibrant democracy, fostering an environment where diverse opinions can be shared and debated. Moreover, legal frameworks often enshrine these protections, reinforcing societal norms that prioritize individual rights and contribute to a just political culture.
