Whose idea was it that the people had the right to overthrow a corrupt ruler?

The idea that people have the right to overthrow a corrupt ruler is often attributed to Enlightenment philosophers, particularly john Locke.

This concept significantly influenced democratic thought and the development of political systems emphasizing individual rights and governmental accountability.
