Many things astronomical are linked to historical events and this is no exception. It was on July 4th 1187 that in northern Palestine near the village of Hattin that the Christian crusader armies of Guy de Lusignan who was king of Jerusalem from 1186-92 were defeated by the Muslim forces of Saladin.
Jerusalem was recaptured by Saladin in October 1187 and many of the gains made by the early crusades were lost.
