Final answer:
The divine right is a doctrine claiming a monarch's right to rule comes directly from God, making them unaccountable to earthly powers and justifying their absolute authority.
Step-by-step explanation:
The term divine right is best defined as the political and religious doctrine that asserts a monarch's legitimacy and right to rule derives directly from the will of God. Not accountable to earthly authority, such as the will of the people, the aristocracy, or any government, a king's power is absolute, as they are considered God's chosen ruler. This concept of legitimacy implies that only God can judge an unjust king, and any effort to challenge the king's authority would be seen as going against the will of God. Historically, the divine right of kings has been used by monarchs to justify their absolute rule.
