Constantine took the name Salusio II (de Lacon) upon his succession, in an attempt to unite the families.
Such confirmations of monastic privileges were commonly associated with accessions at the time and this seems to indicate that Constantine was new to the throne in 1089, fixing the date of his succession to in or shortly before that year.
The bishops and giudici of Cagliari had attained a high level of autonomy and isolation in the past century before Constantine's accession and this prompted papal action, a side-action of the Gregorian reform.
Constantine began to take Cagliari out of its isolation, banking on Benedictine monasticism to reform his country economically, technologically, and ecclesiastically.
Constantine ardently supported the Church and vowed to uphold its rights and abandon the ways of his forefathers: concubinage, incest, and murder.
