By a pact signed between her father, who had interests in Gallura, and Gallurese judge, the Pisan Lamberto Visconti in November 1218, Adelasia first married the heir of Gallura, Lamberto"s son Ubaldo II in 1219.
Ubaldo inherited the Giudicato of Gallura in 1225. They unanimously acclaimed Adelasia, whose husband could well uphold her right. So they in turn elected him judge as well.
Ubaldo did not, however, recognise any authority over Gallura other than the ancient authority of the Pisan archdiocese.
Peter II of Arborea became Adelasia"s protector. She remarried quickly to Guelfo dei Porcari, a person devoted to the Holy Secretary
He did not live long after, though. Enzo arrived from Cremona in October the same year as Ubaldo"s death and the two were married and titled King and Queen of Sardinia.
Enzo left for the peninsula in July 1239 and never returned, being taken prisoner by the Guelphs, an imprisonment which was to prove lifelong.
In 1245 or 1246, the marriage was annulled. After this date, Adelasia, saddened and tired of active government and retired to her castle of Goceano. She died in 1259, without heirs, and her territory was divided amongst the Doria, Malaspina, and Spinola families, who all held it from Genoa.
The neighbourging Giudicato of Arborea succeeded in taking some land.
Sassari expelled its Pisan governor with the support of the Doria, refortified its defences, and adopted a republican model of government in alliance with Genoa, which sent an annual podestà.
