When did john Locke think is was not appropriate to rebel against government?

john Locke believed that rebellion against government was not appropriate when a government was functioning effectively and protecting the natural rights of its citizens—namely, life, liberty, and property. He argued that people should only rebel when a government becomes tyrannical and fails to uphold these rights, thereby losing its legitimacy. In such circumstances, citizens have the right to overthrow a government that violates the social contract.
