Civil liberties are fundamental rights and freedoms that protect individuals from government overreach and ensure participation in a democratic society. They include rights such as freedom of speech, religion, and assembly, which are essential for political expression and dissent. Civil liberties are important in politics because they safeguard individual autonomy and promote a diverse and vibrant discourse. When upheld, they empower citizens to engage in democratic processes, challenge injustices, and hold the government accountable, contributing to a healthy political culture.
