Baldwin V of Jerusalem

Born in 1177 or 1178, Baldwin V became co-king of Jerusalem in 1183 when his uncle Baldwin IV — unable to father heirs because of leprosy — chose the child over other contenders and used the coronation to sideline the boy's stepfather, Guy of Lusignan, whom the court despised. When Baldwin IV died in 1185, the nephew became sole king, but Count Raymond III of Tripoli took over governance as regent. Baldwin V died the following year from causes that went unrecorded. His mother Sibylla succeeded him and promptly elevated Guy to the throne anyway.
