And within a century of migration 3 generations of Afghan Arabs changed the environment of Afghanistan.

By 720 AD the people of Afghanistan were converting to Islam and the population of peasants were growing in numbers and they all accepted Islam as their way of life. From amongst the people of Afghanistan, Abu-Muslim Khorasani emerged as a major politician of the era. By 746 AD while Afghanistan was in a battle between the people and the elite leaders, Abu-Muslim dressed in black robe and declared a holy war against the non-believers. By 752 the region was Islamic and by eliminating the Arab leaders in the area, Abu-Muslim created a large Islamic Kingdom of Khorasan.
