known as Baldwin the Leper
born 1161
died March 1185, Jerusalem
King of Jerusalem (1174–85).
He was crowned at age 13 on the death of his father, but the kingdom was ruled by a series of regents. Baldwin was afflicted with leprosy throughout his short life, which contributed to power struggles among the nobility. His defeat of Saladin in 1177 led to a two-year truce, but in 1183 Saladin captured Aleppo and completed the encirclement of Jerusalem. Baldwin crowned his nephew king in 1183.
