After it was destroyed in a war, Orzocorre moved the capital of Arborea from Tharros to Aurestanni (Oristano), where it remained for the next three centuries.
Orzocorre ruled at a time when Western monasticism and the Gregorian reform were bringing Sardinia closer to the rest of Europe.
In 1074 and 1080, Pope Gregory VII wrote two letters to Orzocorre ordering the clerics of Arborea to shave their beards, as was the Western custom.
[2] James, Archbishop of Cagliari, refused to comply with papal orders and was deprived of his authority.
He was married to Nivata (also Nibatta or Nigata) and had two sons, Torbeno and Orzocorre II, each of whom succeeded him in turn.
