Since the Pope and the prince-electors strongly objected to this agreement, another Treaty was signed at Ulm on 7 January 1326, according to which Frederick would govern Germany as King of the Romans, while Louis would be crowned Emperor by the "people of Rome" under Sciarra Colonna in 1328.
The great Colonna house, at bitter feud with the Gaetani, was his strongest ally, and Sciarra Colonna accompanied Nogaret to Anagni, Boniface's birthplace.
Sciarrillo Colonna and Guillaume de Nogaret (lawyer and royal advisor of Philip IV) were to arrest the pope and bring him to France to stand trial, but this attempt failed.
