The Judicate of Arborea or the Kingdom of Arborea was one of the four independent judicates into which the island of Sardinia was divided in the Middle Ages. It occupied the central-west portion of the island, wedged between Logudoro to the north and east, Cagliari to the south and east, and the Mediterranean Sea to the west. To the northeast and beyond Logudoro was Gallura, with which Arborea had far less interaction. Arborea outlasted her neighbours, surviving well into the 15th century. At its greatest territorial extent it occupied the entire island except the cities of Alghero and Cagliari. The earliest known judicial seat was Tharros, though Oristano served as capital for most of its existence.

The kings or judges of Cagliari were the local rulers of the south of Sardinia during the Middle Ages. Theirs was the largest kingdom and for the eleventh through twelfth centuries contested the supremacy on the island with that of Logudoro. It was often an ally of the Republic of Pisa and an early supporter of Western monasticism.

He was a legislator and a warrior whose reign saw the commencement of massive codification of the laws of his realm and incessant warfare with the Crown of Aragon. He was also a religious man, who had connections to Catherine of Siena. He was, in short, an "wise legislator, able politician, and valiant warrior."
Hugh III was the eldest son and successor of Marianus IV of Arborea and Timbor of Rocabertí. He succeeded in 1376 as Judge of Arborea and Count of Goceano. In most ways he continued and augmented the policies of his father. He has been praised as a legislator who led a saggio e moderato governo: "wise and moderate government."
Peter II was the Judge of Arborea from 1221 to his death. He was also Peter IV, Viscount of Bas. He was "pious and submissive to the church" and his extensive "donations of privileges and judicial lands impoverished his state of glory."

Marianus II was the Judge of Arborea from 1241 to his death. With skilled military action, he came to control more than half of the island of Sardinia.

Brancaleone Doria was the husband of Eleanor of Arborea, regent of the Giudicato of Arborea on the island of Sardinia in the late 14th century. He was a scion of the influential Doria family of the Republic of Genoa, the son of the elder Brancaleone and a woman named Giacomina. On 16 March 1357, he became a vassal of Peter IV of Aragon, the nominal King of Sardinia, to legitimate the possessions of his father on the island.
William II was Viscount of Narbonne (1397-1424) and the nominal Judge of Arborea (1407-1420).
The Sardinian–Aragonese war was a late medieval conflict lasting from 1353 to 1420. The fight was over supremacy of the land and took place between the Judicate of Arborea -- allied with the Sardinian branch of the Doria family and Genoa -- and the Kingdom of Sardinia, the latter of which had been part of the Crown of Aragon since 1324.
