Hugh III of Arborea
Hugh III of Arborea (c. 1337–1383) was the eldest son of Judge Marianus IV. He succeeded his father in 1375 as judge of Arborea and count of Goceano, and continued Marianus's wars against Peter IV of Aragon, allying in 1377 with Louis I of Anjou.
A praised lawgiver, he helped complete the Carta de Logu. In 1383 he and his heiress Benedetta were murdered in a revolt at Oristano; his sister Eleanor then took power as regent for his nephew Frederick.
