Ugone I of Arborea

Ugone I (1178–1211) was giudice of Arborea, son of Sinispella and Hugh Ponç, viscount of Bas. In 1185, aged seven, he succeeded his grandfather under the regency of Ramon de Torroja. A compromise at Oristano in 1192 made Peter di Serra co-judge, but William I of Cagliari invaded in 1195 and captured Peter, forcing Ugone to make peace and cede Arborea.

He reclaimed Bas in 1198 and married William's daughter Preziosa in 1206. He styled himself king of Sardinia. He died at Oristano in 1211, succeeded by his son Peter II.
