What was the idea called that said that kings and queens ruled by the will of God?

The idea that kings and queens ruled by the will of God is known as the "Divine Right of Kings." This doctrine posited that monarchs derived their authority directly from God, making their power absolute and unchallengeable by earthly authority. It was commonly used to justify the authority of monarchs in medieval and early modern Europe. This concept was often invoked to reinforce the legitimacy of royal rule and discourage rebellion or dissent.
