Yes, we have finally come to the end of our series "From Bishop of Rome to the Papal Monarchy." In this episode, Ellen and I talk about the pontificate of Innocent III, which historians see as the apex of the papal monarchy. Among the topics we cover are Innocent III's ideology of Caesaropapism, his contribution to the crusading movement, his combat against heresy, his defense of the papal states, and his dedication to Church Reform. Innocent III was the most powerful and effective pope of the Middle Ages.  His control over the Roman Catholic episcopate was uncontested, as evidenced by the Fourth Lateran Council. But his Caesaropapism, his assertion of papal supremacy over both the clergy and the laity, including Christian rulers, was more theoretical than real. He claimed to be the supreme judge over the rulers of Christendom, and was successful in doing so in a number of high profile cases, but his successes were contingent upon the need of those kings either to have papal support or, at the very least, not to be opposed by the papacy. Similarly, he could launch crusades against the Church’s domestic and foreign enemies, but once a crusade was ongoing, he had little power to direct it—even when the crusaders were disobeying his direct orders, as happened twice during the Fourth Crusade. When examined closely, papal supremacy over Christendom was always contingent, even during the apex of the papal monarchy.
