Page 23: "Salah ed-Din (Saladin) was the son of Ayûb, and grandson of Shadi, a Rawadiya Kurd of the great Hadâniya Tribe. He was thus of Kurd descent. Several of his bravest warriors and most trusted counsellors were Kurds, and during his reign, and that of his brother el'Adel, Kurds ruled in Armenia, Mesopotamia, Syria, Palestine, Egypt, and Arabia."
