Guy of Lusignan
In 1182, Baldwin IV, now blind and bed-ridden, appointed Guy of Lusignan as his regent. Guy abused his authority and ignored Raynald of Châtillon's harassment of Muslim trade caravans, causing a diplomatic crisis between Jerusalem and Egypt-Syria. Guy's apparent excess caution at Kerak caused King Baldwin to depose Guy as regent and lift Saladin's siege there, during the wedding of young princess Isabella and Humphrey IV of Toron.
