Biography
Constantine II de Martis (died December 1198) was the ruler of Logudoro from around 1186 until his death. He was the son of Barisone II and Preziosa de Orrubu and was involved in government matters since 1170. Constantine took power during a time of significant competition between the Italian maritime republics of Genoa and Pisa for control over Sardinian territories. Documents from the time describe his rule as tyrannical, but details are not clear.
Constantine's reign was marked by political strategies involving the Sardinian giudicati and their Italian allies. When he became the ruler, Logudoro and Arborea were allied with Genoa, while Gallura and Cagliari supported Pisa. The death of Barisone II of Arborea in 1185 led to a succession crisis that greatly influenced Constantine's foreign policy. Pisa and Genoa backed opposing contenders for the Arborean throne—Pisa supported Peter of Serra, and Genoa backed Hugh of Bas.
The political situation changed significantly when Constantine's brother, Peter of Torres, ruler of Cagliari, rebelled against Pisa and allied with Genoa. This rebellion prompted Pisa to send a military force in 1189 under Obert, Margrave of Massa, who successfully invaded Cagliari and put his son William in charge. Peter then sought refuge with Constantine in Porto Torres, adding to the complexity of alliances on the island.
On June 10, 1191, Constantine settled his alliance with Genoa through a formal treaty that gave Genoese merchants numerous benefits in Logudoro, such as property rights, citizenship, tax-free trade, and access to justice. In return, Constantine agreed to support Genoa's efforts against Pisa and Arborea. This alliance allowed Constantine and William of Cagliari to jointly invade Arborea, causing Hugh to flee and capturing Peter. They divided Arborea between them, but the partnership was short-lived. Genoa soon convinced Constantine to oppose William, leading to Constantine's defeat and eventual reconciliation with his former ally.
Before Fame
Constantine II was born into the ruling family of Logudoro in the mid-12th century, at a time when Sardinia's giudicati acted like semi-independent kingdoms caught between rival Italian maritime powers. His father, Barisone II, saw his potential early on and got him involved in government matters by 1170, when Constantine was probably in his twenties.
The path to his eventual rule was carefully planned through this long period of co-leadership, giving him practical experience in diplomacy and governance during one of Sardinia's most politically unstable times. His training in leadership coincided with the growing competition between Genoa and Pisa for control in Sardinia, getting him ready for the tricky alliances that would shape his reign.
