One of the most unifying elements of the Medieval Period was the Roman Catholic Church. All classes and ranks of people, whether that be nobles, peasants or tradesmen, were profoundly affected by the rulings of the church. A hierachy existed within the clergy. Following the pope, in order of rank, there were bishops, priests, monks and nuns. In the latter part of the Middle Ages, the pope, as head of the church, had a huge influence over the monarchy and total control of the clergy. In this episode Eleanor Janega explores the lives of those who made up the single largest unifying organization in medieval Europe.
