The Haqqani Network was an Afghan guerrilla insurgent group which was founded by Jalaluddin Haqqani during the 1980s. Haqqani's organization was nurtured by the American CIA, the Pakistani ISI, and private donors from Saudi Arabia due to its resistance to the Soviet Army during the Soviet-Afghan War. The Haqqanis imported foreign fighters during the conflict, and among these fighters were Arab volunteers Abdullah Azzam and Osama bin Laden. In 1994, during the Afghan Civil War, the Haqqani Network became a distinct faction of Mujahideen, and, a year later, the Haqqani Network pledged allegiance to the Taliban. The Haqqani Network came to have between 4,000 and 15,000 fighters, and - motivated by Deobandi fundamentalism - they waged a guerrilla war against their formed US allies in the Afghanistan War.
