Baldwin IV of Jerusalem

Baldwin IV (1161–1185), the Leper King, succeeded his father Amalric in 1174 at the age of thirteen and was tutored by William of Tyre, who first noticed his leprosy. Raymond III of Tripoli acted as regent until 1176.

In 1177 Baldwin routed Saladin at Montgisard. He had arranged his sister Sibylla's marriage to Guy of Lusignan in 1180, but Guy's conduct later cost him the king's trust.

Blinded and enfeebled by 1183, Baldwin had his nephew Baldwin V crowned co-king and was carried in a litter to relieve Kerak. He arranged for Raymond to be regent before dying in 1185; two years later Saladin defeated the kingdom's army at Hattin.
