History: During the Crusades Cyprus came under the rule of the Lusignan family. The conquest of Cyprus had been brutal and it's population was devestated. Lord Lusignan and the crusaders lost much support in the mostly Greek populace of Cyprus. Many of whom had lost large portions of their families to violence and famine related to the conquest of the island. The crusaders had not always treated the local orthodox well. While the Islamic army defending the island pursued a scorched earth strategy. Wanting to strengthen his position in the face of local unrest, Lord Lusignan encouraged the settlement of Western Christians. Lord Lusignan also introduced Frankish style feudalism to Cyprus, giving many of his supporters titles in Cyprus. The Western population influx from many different cultures and linguistic backgrounds from Western Europe quickly began to speak a form of creol with mostly Romance roots. This creole formed the basis for todays Cypriot Romance. Today speakers of Cypriot Romance make up the majority of the population, with around 55% of the population. Greek speakers make up most of the rest. There is also Armenian, Hebrew and Syriac communities on the island. Historically before 1800AD Cypriot Romance made up a much larger portion of the islands population, but overtime due to emigration declined proportionally to other lingustic communities.
