The island was conquered from Isaac Comnenus, a rival Byzantine emperor, in 1191 by King Richard I of England during the Third Crusade. Richard then sold it to the Knights Templar, who in turn sold it to King Guy of Jerusalem in 1192 after the failure of Richard's crusade. A small minority Roman Catholic population of the island was mainly confined to the coastal cities, such as Nicosia and Famagusta but remained in control, while the Greek inhabitants lived in the countryside; this was much the same as the arrangement in the Kingdom of Jerusalem. The independent Eastern Orthodox Church of Cyprus, with its own archbishop and subject to no patriarch, was allowed to remain on the island, but the Latin Church largely displaced it in power.
After the death of Amalric of Lusignan, the Kingdom continually passed to a series of young boys who grew up as king. The Ibelin family, which had held much power in Jerusalem prior its downfall, acted as regents during these early years. In 1229 one of the Ibelin regents was forced out of power by Frederick II, Holy Roman Emperor, who brought the struggle between the Guelphs and Ghibellines to the island. Frederick's supporters were defeated in this struggle by 1233, although it lasted longer in Palestine and in Europe. Frederick's Hohenstaufen descendants continued to rule as kings of Jerusalem until 1268 when Hugh I claimed the title for himself upon the death of Conradin, thus uniting the two kingdoms. The territory in Palestine was finally lost while Henry II was king in 1291, but the kings of Cyprus continued to claim the title.
Like Jerusalem, Cyprus had a Haute Cour (High Court), although it was less powerful than it had been in Jerusalem. The island was richer and more feudal than Jerusalem, so the king had more personal wealth and could afford to ignore the Haute Cour. However, the king was often in conflict with the Italian merchants, especially because Cyprus had become the centre of European trade with Africa and Asia after the fall of Acre in 1291.
The kingdom eventually came to be dominated more and more in the 14th century by the Genoese merchants. Cyprus therefore sided with the Avignon Papacy in the Great Schism, in the hope that the French would be able to drive out the Italians. The Mameluks then made the kingdom a tributary state in 1426; the remaining monarchs gradually lost all power, until 1489 when the last Queen, Catherine Cornaro, was forced to sell the island to Venice.
