Until the independence of Pakistan in 1947, Fateh Jang was under British rule, the Imperial Gazetteer of India describes the Tehsil as follows:

"Fatahjang (Fatehjang), easternmost tehsil of Attock District, Punjab, lying between 33°10′ and 33°45′ N. and 72°23′ and 73°1′ E., with an area of 866 square miles. The population in 1901 was 114,849, compared with 113,041 in 1891. It contains 203 villages, of which Fatahjang (population, 4,825) is the headquarters. The land revenue and cesses amounted in 1903-4 to 1.9 lakhs. The tahsil is divided into three distinct parts. North of the Kala-Chitta is a small plain much cut up by ravines. South of the Khairi-Murat. (near Dhari village) is the fertile Sohan valley, while between the two ranges of hills lies a rough plain, narrow in the east and broadening towards the west".
