The House of Lusignan (/ˈluːzɪn.jɒn/ LOO-zin-yon; French: [lyziɲɑ̃]) was a royal house of French origin, which at various times ruled several principalities in Europe and the Levant, including the kingdoms of Jerusalem, Cyprus, and Armenia, from the 12th through the 15th centuries during the Middle Ages. It also had great influence in England and France.
The family originated in Lusignan, in Poitou, western France, in the early 10th century. By the end of the 11th century, the family had risen to become the most prominent petty lords in the region from their castle at Lusignan. In the late 12th century, through marriages and inheritance, a cadet branch of the family came to control the kingdoms of Jerusalem and Cyprus. In the early 13th century, the main branch succeeded to the Counties of La Marche and Angoulême.
