every redoubt on the island save the stronghold of Castel di Castro. He even menaced Sassari in 1354. Later that year, Peter IV landed on the island at Nulauro. Marianus promptly began a guerilla war of ambushes against royal troops until, at the end of 1355, a brief peace was signed at Sanluri by which Marianus renounced Alghero. The peace lasted two years, during which Marianus reinforced his armies and the country progressed favourably economically. In 1365, the war resumed with full force. Pope Urban V confirmed Arborean possession of the whole of the island save Sassari, Alghero, and Cagliari. Peter IV, however, sent a fleet commanded by Pere de Luna to lead an Aragonese army deep into Arborea, bypassing other fortifications to assault Oristano. The Aragonese troops were trapped between the Arborean armies commanded by Marianus and his son, the future Hugh III, and defeated. In 1368, Marianus finally occupied Sassari. He was preparing another campaign when he died in 1376. Legislation During the two-year peace, Marianus began the work of putting down in writing the oral laws and customs of Arborea. The chief legislative work of his lifetime was the Codice Rurale, which his daughter Eleanor later incorporated into her massive Carta de Logu. His great work, however, was cut short by his sudden death of the bubonic plague in 1376. Wife and children By his wife Timbora, Marianus left four children: Hugh III, his successor Eleanor, his son's successor Beatrice (died 1377), married (1363) to Aimery VI of Narbonne an unnamed daughter who died young on 14 January 1343 Timbora was still living in 1361, but that is the last she is heard of.
