Excurs: Medical negligence in the Laws of the Kingdom of Jerusalem
The Assis de la Cour des Bourgeois from 1240-44 is our principal source about medical legislation in the crusading states. It lays out the mechanisms of medical licensing and punishment for medical negligence.
In case of medical negligence, a distinction is made if the victim is a slave or a free man.
Furthermore, a distinction is made if the illness can be realistically healed by a physician (like a bone fracture) or not (like measles).
If a physician crippled or killed a slave because of medical negligence he was bound to pay compensation to the owner.
If a physician killed or crippled a free man because of medical negligence he was submitted to various physical punishments such as the amputation of the right thumb or even hanging.
Medical the Jerusalem Trilogy the comparatively high standard of medical care in the crusader states is recognized.
