Isaaq

The Isaaq (also Isaq, Ishaak) (Somali language: Reer Sheik Isaxaaq); is one of the main Somali clans. The Isaaq mainly live in Somaliland and the Somali Region of  Ethiopia. The populations of the four major cities of Somaliland–  Hargeisa, Burco, Berbera, and Ceerigaabo – are predominantly Isaaq. Tradition states that the Isaaq clan was founded by the arrival of Sheikh Isaq from Arabia in the twelfth or thirteenth centuries. He settled at the coastal town of Maydh in modern day Somaliland, where he married into the local Dir clan. His tomb is in Maydh.
