List of Sardinian monarchs

Sardinia is traditionally known to have been initially ruled by the Nuragic civilization, which was followed by Greek colonization, conquest by the Carthaginians, and occupied by the Romans for around a thousand years, including the rule of the Vandals in the 5th and 6th centuries AD. Before the foundation of the Kingdom of Sardinia, Sardinia was ruled by judices, and some rulers obtained the title of King of Sardinia by the Holy Roman Emperor but did not gain effective authority to rule it. The title of as Rex Sardiniae et Corsicae (King of Sardinia and Corsica) was first established in 1297, when Pope Boniface VIII gave a royal investiture to James II of Aragon.
