Marianus II of Arborea

Marianus II (died 1297) was Judge of Arborea from 1241, succeeding his father Peter II as a child under the regency of William of Capraia. After William died in 1264, Marianus shared power with his son Nicholas; in 1270 he imprisoned Nicholas, and had him killed in 1274.

From 1274 he campaigned in Cagliari and Logudoro. A Pisan citizen from 1265, he nevertheless called in Peter III of Aragon against Cagliari in 1284. He was wounded at the siege of Villa di Chiesa and died in 1297, succeeded by his son John.
