The Isaaq is a major Somali clan. It is one of the largest Somali clan families in the Horn of Africa, with a large and densely populated traditional territory.
The Isaaq people claim in a traditional legend to have descended from Sheikh Ishaaq bin Ahmed, an Islamic scholar who purportedly traveled to Somaliland in the 12th or 13th century and married two women; one from the local Dir clan. He is said to have sired eight sons who are the common ancestors of the clans of the Isaaq clan-family. He remained in Maydh until his death.
