Following his return, Gaveston's relationship with the major barons became increasingly difficult. He was considered arrogant, and he took to referring to the earls by offensive names, including calling one of their more powerful members the "dog of Warwick". The Earl of Lancaster and Gaveston's enemies refused to attend parliament in 1310 because Gaveston would be present. Edward was facing increasing financial problems, owing £22,000 to his Frescobaldi Italian bankers, and facing protests about how he was using his right of prises to acquire supplies for the war in Scotland. His attempts to raise an army for Scotland collapsed and the earls suspended the collection of the new taxes.
