 As a result, Isa swore an oath of loyalty to Baybars and afterward participated in every Mamluk campaign against the Ilkhanids.The first of these campaigns occurred soon after Isa's meeting with Baybars, when he led raids against the Ilkhanids in Edessa and Harran in southern Anatolia.In 1273, Isa led raids against Ilkhanid-held Anbar in western Iraq on orders from Baybars, possibly to divert Ilkhanid forces from an expedition against Syria.
