Seddori

Seddori, known in Italian as Sanluri, stands on the Campidano plain between Cagliari and the lands of Arborea. Its fortified settlement became the scene of a decisive battle on 30 June 1409. Martin I of Sicily led an Aragonese army against William of Narbonne's Arborean forces and defeated them, opening the way to further conquest. In 1436 the Crown of Aragon made Sanluri a viscountcy for Giovanni de Sena.
