 Under Emir Sultan ibn Ali (r. 1098–1154), the Banu Munqidh alternated between combating the Crusaders who landed in Syria in 1099 and paying tribute to them.During this period, the family also had to contend with Ismai'li newcomers encroaching on their domains.To firmly protect the emirate, Sultan ultimately put the Banu Munqidh under Zengid suzerainty.
