The fort was built in 1889 by
Abdur Rahman, the 19th-century “Iron Amir,” the first ruler to unite Afghanistan. Then known as
Dehdadi after the village nearby, it was built with British funds and intended both to defend against Russian invasion and to suppress revolts by Uzbek tribes. Rahman described it as "the largest and strongest fort that had ever been built in Afghanistan." It took 18,000 workers 12 years to complete it. In 1929, about 300 Russian troops were besieged inside the fort by 20,000 Turkmens. The name Qala-i-Jangi was probably not given to the fort until the 1940s. The Russians, with Dostum’s support, occupied it again after their 1979 invasion. Mujahideen attacked Qala-i Jangi in 1981, removing 170 pro-Soviet Afghan soldiers. The Taliban occupied the fort for most of the time from 1994 to 2001.
Abdul Rashid Dostum, of the Northern Alliance, held the fort briefly in 1997, with 20,000 militia. ==Description==
