Guy of Lusignan
Guy of Lusignan (c. 1150–1194), a Poitevin knight and youngest son of Hugh VIII, married Sibylla, sister of Jerusalem's King Baldwin IV, in 1180. Baldwin made him regent in 1183 but resumed power that year; in 1186 Sibylla became queen and crowned Guy beside her.
At Hattin in 1187 his army was destroyed and Saladin captured him; Jerusalem fell three months later. Released in 1188, he began the siege of Acre in 1189. Deprived of the Jerusalem crown in 1192, he received Cyprus from Richard I of England and ruled until his death in 1194, succeeded by his brother Aimery.
