Editing Pope Adrian IV (section)

===Capture of Arnold===
Adrian angled for the support of the Emperor in capturing the heretic Arnold.{{citation needed|date=July 2021}} Arnold was captured by Imperial troops{{sfn|Freed|2016|p=144}} in summer 1155. Arrested and tried in a Papal court{{sfn|Freed|2016|p=144}} for rebellion rather than heresy, he was [[Hanging|hanged]] and his body burnt.{{sfn|Baumgartner|2003b|p=32}} Adrian claimed that Arnold's execution had been on the initiative of the [[prefect]] of Rome, but some contemporary observers, such as [[Gerhoh of Reichersberg]], suspected Adrian of ordering the execution himself.{{sfn|Morris|1989|p=406}} The Emperor's willingness to assist the Pope in his own city, and help him crush his enemies, was an explicit recognition from Barbarossa of the Pope's possession of Rome.{{sfn|Freed|2016|p=144}} Papal relations with the lords of Campania were already tense, as they, in the Pope's view, were little more than [[Robber baron (feudalism)|robber barons]], who both fought among each other and robbed pilgrims from the south on their way to Rome.{{sfn|Eden|2006|p=293}}
