Hugh I of Arborea

He ascended to the throne of Arborea in 1185 when he was only seven years old, under the regency of Ramon de Torroja, the brother in law of Agalbursa, through her sister Gaia.

[4] Agalbursa was the widow of Barisone II, and paternal aunt of Hugh himself.

In 1192, a compromise was reached at Oristano whereby Peter di Serra, Barisone's eldest son by his first wife Pellegrina di Lacon, was recognised as co-judike.

[5] In 1195, William I of Cagliari invaded Arborea, imprisoning Peter and besieging Oristano, forcing Hugh to sign a pact ceding his territories and engaging him to marry Preziosa, William's daughter and a relative of the house of Peter.

Both Hughs died in 1211, the regent succeeded in the regency by his sister Eldiarda, wife of Ramon de Palau, and the king succeeded by his son Peter II.
