The Orakzai tribes take their name, which literally means the lost son (Wrak Dzoy), from a romantic legend about their ancestor, Sikandar Shah, who was a prince from Iran, was exiled or lost, and after many adventures married and ruled in Tirah. The tribal area now forming Orakzai Agency was previously included in Frontier Region Kohat district and remained as such until 30 November 1973. The Bila
nd Khel, a small pocket measuring about 6.5 square kilometres, is also part of this agency and lies a couple of kilometres off Thall, bordering North Waziristan and Kurram agencies. Responding to a long-standing demand of the Orakzais, the then President of Pakistan announced the creation of Orakzai Agency on 3 November 1973 and was formally inaugurated on 1 December 1973. Prior to its upgrading to agency status, this area was administered as a Frontier Region of the Kohat district by the Deputy Commissioner of Kohat. The Upper sub-division comprises two Tehsils, Upper Tehsil and Ismailzai Tehsil, while the Lower sub-division also has two Tehsils, Lower Tehsil and Central Tehsil. The land of the Orakzai tribes is located between 33° -33' to 33° -54' north latitudes and 70° -36' to 71° -22' east longitudes. It is bounded in the north by Khyber Agency, in the east by FR Kohat, in the south by Kohat and Hangu districts, and in the west by Kurram Agency. The total area of the agency is 1,538 square kilometres
