 The split of JUI into two factions was due to dissent over the policy of president Zia-ul-Haq of supporting Mujahideen outfits in the Afghanistan war during the 1980s.A more recent faction known as JUI-N, split off JUI-F in 2008, is also unrepresented at the national level.The JUI follows the Sunni (deobandi) school.
