August 1059 CE
The papacy has been hostile toward the Normans until this time, considering them an anarchist force that upset the political structure in southern Italy—a structure based on a balance of power between the Greeks and the Lombards.
The schism that had taken place between the Greek and Latin churches in 1054 has steadily worsened the relations between Constantinople and Rome, and eventually the papacy had realized that Norman conquests over the Greeks in Italy can work to its advantage.
Robert Guiscard’s plan to expel the Arabs from Sicily and restore Christianity to the island also finds favor in the eyes of Pope Nicholas II.
Guiscard, in his progression from gang leader to commander of mercenary troops to conqueror, has emerged as a shrewd and perspicacious political figure.
Nicholas II, to secure his position, had at once entered into relations with the Normans.
The Pope wants to re-take Sicily for Christianity, and he sees the Normans as the perfect force to crush the Muslims.
The Normans are by this time firmly established in southern Italy, and later in the year 1059 the new alliance is cemented at Melfi, where the Pope, accompanied by Hildebrand, Cardinal Humbert and the abbot Desiderius of Monte Cassino, solemnly invests Robert Guiscard with the duchies of Apulia, Calabria and Sicily, and Richard of Aversa with the principality of Capua, in return for oaths of fealty and the promise of assistance in guarding the rights of the Church.
This despite the inconvenient fact that the Greeks still hold Italy's toe and heel.
There are two reasons for this change in papal politics.
First, the Normans had shown to be a strong (and close by) enemy, while the emperor a weak (and far away) ally.
Second, Pope Nicholas II had decided to cut the bonds between the Roman Church and the Holy Roman emperors, reclaiming for "the Roman cardinals the right to elect the pope, thus reducing the importance of the emperor and initiating the stirrings of what will come to be called the Investiture Controversy.
