Талибан был основан в 1994 году:

Mohammed Omar is the founder and has been serving as the spiritual leader of the Taliban since its foundation in 1994.[26]

Если посмотреть на биографию Моххамеда Омара, то окажется, что он как раз и есть один из муджахедов воевавших против советских войск в Афганистане.

Omar fought as a rebel soldier with the anti-Soviet Mujahideen under the command of Nek Mohammad and others, but did not fight against the Najibullah regime between 1991 and 1992.[24] It was reported that he was thin, but tall and strongly built, and "a crack marksman who had destroyed many Soviet tanks during the Afghan War."[34]

Его причастность к основанию Талибана:

Following the Soviet withdrawal from Afghanistan in 1989 and the collapse of Najibullah's regime in 1992, the country fell into chaos as various mujahideen factions fought for control. Mullah Omar returned to Singesar[when?] and founded a madrassah.[38]

> Кого именно сверг Талибан в 1996 году?

Массуда? Другого муджахеда кстати, "умеренно-религиозного" толка.
