The Kingdom of Cyprus was a Crusader kingdom on the island of Cyprus in the high and late Middle Ages, between 1192 and 1489. It was ruled by the French House of Lusignan.
The island was conquered from Isaac Comnenus, an upstart local governor and self-proclaimed emperor claiming the empire of Constantinople, 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 Guy of Lusignan, jure uxoris King of Jerusalem, in 1192 after the failure of Richard's crusade and when Guy was dispossessed of his late wife's kingdom. His brother and successor, Amalric I of Cyprus, received the royal crown and title from Henry VI, Holy Roman Emperor. A small minority Roman Catholic population of the island was mainly confined to some coastal cities, such as Famagusta, as well as inland Nicosia, the traditional capital. Roman Catholics kept the reins of power and 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 stature and holding property.
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 III of Cyprus claimed the title and its territory of Acre for himself upon the death of Conrad III of Jerusalem, 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.
