The papal deposing power was the most powerful tool of the political authority claimed by and on behalf of the Roman Pontiff, in medieval and early modern thought, amounting to the assertion of the Pope's power to declare a Christian monarch heretical and powerless to rule. Pope Gregory VII's Dictatus Papae (c. 1075) claimed for the Pope "that it may be permitted to him to depose emperors" (12) and asserted the papal power to "absolve subjects from their fealty to wicked men" (27).
