Why do people have a right to revolution?

People have a right to revolution when a government becomes oppressive or fails to protect the fundamental rights and freedoms of its citizens. This right is rooted in the belief that authority derives from the consent of the governed; when that consent is violated, people are justified in seeking to change or overthrow that government. Historical precedents, such as the American and French revolutions, illustrate the idea that individuals must have the power to resist tyranny to secure their liberty and justice. Ultimately, the right to revolution serves as a safeguard against despotism and a means for citizens to reclaim their autonomy.
