鲍德温四世
Baldwin IV of Jerusalem became king on 5 July 1174 at the age of 13. As a leper he was not expected to live long, and served with a number of regents, and served as co-ruler with his cousin Baldwin V of Jerusalem beginning in 1183. Baldwin IV's rule began simultaneously with the death of Nūr-ad-Din and the rise of Saladin. Notably, Baldwin and Raynald of Châtillon defeated Saladin at the celebrated Battle of Montgisard on 25 November 1177, and repelled his attacks at the Battle of Belvoir Castle in 1182 and later in the Siege of Kerak of 1183. He died on 6 March 1185.
