ImanghasatenImanghasaten, a Tuareg people of the north central Sahara, members of the Azjar confederacy, although traditionally descended from the Megarha Arabs of the Wady Shiati in Fezzan. At present they are entirely assimilated in dress, speech, and customs to the other Azjar Tuaregs, amongst whom they have their camping grounds. Since the memorable expedition of Denham, Clapperton, and Oudney (1822), the Imanghasaten have always been the friends and protectors of English explorers, while the neighbouring Oreighen have taken the French under their protection. But for this friendly disposition of some of the Tuaregtribes no Europeans could have ever penetrated from the Mediterranean seaboard across the Sahara to Sudan. (H. Duveyrier, Les Touareg du Nord.)
