 It seems especially unlikely in light of the apparent weakness of Diego and Pedro's alliance at the time, and the lack of support for them in Santiago de Compostela itself.In the spring of 1117, probably in June, Urraca, after campaigning against Theresa in southern Galicia, came to Santiago to mediate between Diego and the council ("concejo"), which had been ruling the town "de facto" for the past year.During a private meeting between Urraca and Diego in the episcopal palace, the townspeople revolted and forced the two to take refuge in a cathedral tower then under construction, which they promptly lit on fire.
