 On 30 June 1089, Constantine confirmed that the monastery of Saint-Victor in Marseille possessed the Sardinian monasteries of San Giorgio di Decimo and San Genesio di Uta.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.
