Biography
Ubaldo II Visconti (1207–1238) was Judge of Gallura from 1225 until his death and one of the most powerful rulers in 13th-century Sardinia. Born to Lamberto di Eldizio and Elena de Lacon, he was part of the influential Visconti family of Pisa, which had gained significant control over Sardinian political issues. His marriage to Adelasia of Torres in 1219, arranged by his father through a pact with Marianus II of Torres in November 1218, played a key role in increasing his power across the island.
When Ubaldo took over Gallura in 1225, he showed great skill in politics and military strategy. After his uncle Ubaldo I Visconti died in 1230, he quickly moved into the Giudicato of Cagliari to keep Pisan family control, acting as regent for Benedetta until 1232. His territorial aspirations grew further after his father-in-law Marianus II died in 1232, and Barisone III died in 1236 without heirs.
When the Logudorese nobles chose Adelasia as the successor to Barisone III in 1236, Ubaldo's dominion expanded greatly. Through his wife's inheritance, he gained control of Torres, making him ruler of three of Sardinia's four giudicati, leaving only Arborea beyond his reach. This power consolidation marked the peak of Pisan influence on the island and made Ubaldo a formidable figure in the western Mediterranean.
Ubaldo's dealings with papal power were tricky and politically important. In 1237, Pope Gregory IX sent chaplain Alexander to Torres to secure recognition of papal control. At the palace of Ardara, in front of Camaldolese monks from S. Trinità di Saccargia, Adelasia vowed vassalage, which Ubaldo confirmed, handing over the castle of Monte Acuto to the bishop of Ampurias as a guarantee. However, Ubaldo insisted that Gallura stayed under the traditional control of the Pisan archdiocese, refusing to accept papal supremacy over his main domain. He wrote his will in January 1237 at Silki, naming his nephew John as successor, although this plan was undone by imperial actions after his death in 1238.
Before Fame
Ubaldo got his start thanks to his birth into the influential Visconti family of Pisa, which had already gained a strong hold over Sardinian politics through alliances and control of territories. His father, Lamberto di Eldizio, understood the importance of marriage alliances during medieval times, so he arranged a marriage agreement with Marianus II of Torres in 1218 when Ubaldo was just eleven.
The marriage to Adelasia of Torres in 1219 quickly faced opposition from the Pope because of conflicts between Rome and Pisan interests. Pope Honorius III sent his chaplain Bartolomeo to annul the marriage, but the effort failed, allowing the Pisan-Logudorese alliance to remain intact. This early political win showed the power of the Visconti network and paved the way for Ubaldo's later expansion in Sardinia.
