Imperial Acts of Parliament.
The Divine Right of Kings is a European political and religious doctrine of political absolutism. Such doctrines are largely, though not exclusively, associated with the medieval and ancien régime eras. It states that a monarch owes his rule to the will of God, not to the will of his subjects, parliament, the aristocracy or any other competing authority. This doctrine continued with the claim that any attempt to depose a monarch or to restrict his powers ran contrary to the will of God.
Its symbolism remains in the coronations of the British monarchs, in which they are anointed with Holy oils by the Archbishop of Canterbury, thereby ordaining them to monarchy. It is further evidenced by efforts to trace the genealogy of European monarchs to King David of the Old Testament, in the apparent belief that it legitimizes the rule of the present monarch. The king or queen of the United Kingdom is the last monarch still to undergo such a ceremony, which in other countries has been replaced by an inauguration or other declaration. It is the reason why the British Royal Family's motto is Dieu Et Mon Droit (God and my [birth] Right - i.e. I rule with God's blessing).
