Again..the Taliban didn't exist. They came about as an organized group asfter the Soviets left in 1989. The Taliban ("Students of Islamic Knowledge Movement") ruled Afghanistan from 1996 until 2001. They came to power during Afghanistan's long civil war. The Taliban was ousted from power in December 2001 by the U.S. military and Afghani opposition forces in response to the September 11, 2001, terrorist attack on the U.S.
Groups of taliban ("religious students") were loosely organized on a regional basis during the occupation and civil war. Although they represented a potentially huge force, they didn't emerge as a united entity until the taliban of Kandahar made their move in 1994. In late 1994, a group of well-trained taliban were chosen by Pakistan to protect a convoy trying to open a trade route from Pakistan to Central Asia. They proved an able force, fighting off rival mujahideen and warlords. The taliban then went on to take the city of Kandahar, beginning a surprising advance that ended with their capture of Kabul in September 1996.
