Ubaldo of Gallura

Ubaldo II Visconti, son of Lamberto di Eldizio and Elena de Lacon, was the Judge of Gallura from 1225 to his death in 1238.

Pope Honorius III, enemy of the Pisans, immediately sent his chaplain Bartolomeo to annul the marriage, but he failed and the pact between Pisa and Logudoro stood.

In 1230, when his uncle, Ubaldo I Visconti, died, he invaded the giudicato of Cagliari to assure the continued influence of his Pisan family there.

At the palace of Ardara, in the presence of the Camaldolese abbot and monks of S. Trinità di Saccargia, she made the oath of vassalage and Ubaldo affirmed it, giving over the castle of Monte Acuto to the bishop of Ampurias as a guarantee of his good faith.

His nephew John was nominated to succeed him, but his widow's second husband, Enzo, took control of both Gallura and Logudoro and was granted the title King of Sardinia by his father, the Emperor Frederick II.
