Pope Stephen III
In 771 the new King of the Lombards, Desiderius, devised a plot to conquer Rome and seize Pope Stephen III during a feigned pilgrimage within its walls. His main ally was one Paulus Afiarta, chief of the Lombard party within the city. He conquered Rome in 772 but angered Charlemagne. However the plan failed, and Stephens' successor, Pope Hadrian I called Charlemagne against Desiderius, who was finally defeated in 773. The Lombard Kingdom was no more, and now Rome entered into the orbit of a new, greater political institution.
