Sardinian–Aragonese war
The Sardinian–Aragonese war was a late medieval conflict lasting from 1353 to 1420. The battle 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.
