Pressures building within the Curia, together with ongoing conflicts among the Roman nobility, would erupt after the death of Callixtus II in 1124. The pontificates of Urban II and Paschal II saw an expansion in the College of Cardinals of Italian clerics that strengthened the local Roman influence. These cardinals were reluctant to meet with the batch of cardinals recently promoted by Callixtus II, who were mainly French or Burgundian. As far as the older cardinals were concerned, these newer cardinals were dangerous innovators, and they were determined to resist their increasing influence. The northern cardinals, led by Cardinal Aymeric de Bourgogne (the Papal Chancellor), were equally determined to ensure that the elected pope would be one of their candidates. Both groups looked towards the great Roman families for support.
