The Islamic Movement of Uzbekistan was a militant Islamist group formed in 1998 by Islamic ideologue Tahir Yuldashev and former Soviet paratrooper Juma Namangani; both ethnic Uzbeks from the Fergana Valley. Its original objective was to overthrow President Islam Karimov of Uzbekistan and create an Islamic state under Sharia; however, in subsequent years, it reinvented itself as an ally of Al-Qaeda. The group also maintained relations with Afghan Taliban in the 1990s. However, later on, relations between the Afghan Taliban and the IMU started declining.
