House of Lusignan
At that point, Hugh of Antioch, whose maternal grandfather had been Hugh I of Cyprus, took the name Lusignan, thus founding the second House of Lusignan. He succeeded his deceased cousin as King of Cyprus. In 1268, following the execution of Conradin, he was crowned King of Jerusalem. Hugh was frustrated by dealing with the different factions of Jerusalem nobles, and in 1276 he left for Cyprus. Saint Thomas Aquinas wrote "On Kingship" for Hugh.
