YUSAFZAI, a large group of Pathan tribes, originally immigrants from the neighbourhood of Kandahar, which includes those of the Black Mountain, the Bunerwals, the Swatis, the people of Dir and the Panjkora valley, and also the inhabitants of the Yusafzai plain in Peshawar district of the North-West Frontier Province of India. Three sections of the tribe, the Hassanzais, Akazais and Chagarzais, inhabit the W. slopes of the Black Mountain, and the Yusafzai country stretches thence to the Utman Khel territory. The trans-border Yusafzais are estimated at 65,000 fighting men, giving a total population of about 250,000. The Yusafzais are said to be descended from one Mandai, who had two sons, Umar and Yusaf. Umar died, leaving one son, Mandan; from Mandan and Yusaf come the two primary divisions of the Yusafzais, which are split into numerous subdivisions, including the Isazais, Malizais, Akazais, Ranizais and Utmanzais.
