 Most Christian authors who wrote of Raynald in the 12th and 13th centuries were influenced by Raynald 's political opponent , William of Tyre . The author of the Estoire of Eracles stated that Raynald 's attack against a caravan at the turn of 1186 and 1187 was the " reason of the loss of the Kingdom of Jerusalem " . Modern historians have usually also treated Raynald as a " maverick who did more harm to the Christian than to the [ Muslim ] cause " . Runciman describes him as a marauder who could not resist the temptation presented by the rich caravans passing through Oultrejordain . Runciman argues that Raynald attacked a caravan during the 1180 truce because he " could not understand a policy that ran counter to his wishes " . According to Barber , Raynald 's behavior during the reign of Guy of Lusignan shows that the kingdom had broken up into " a collection of semi @-@ autonomous fiefdoms " by that time .
