There are more Sunni than Shia Muslims among the residents. Islam was brought to the ancestors of modern Uzbeks during the eighth century when the Arabs entered Central Asia. Islam initially took hold in the southern portions of Turkestan and thereafter gradually spread northward. Islamic customs were broadly adopted by the ruling elite, and they began patronage of scholars and conquerors such as Muhammad al-Bukhari, Al-Tirmidhi, al-Biruni, Avicenna, Tamerlane, Ulugh Begh, and Babur.Atabaki, Touraj.

He also constructed one of his finest buildings at the tomb of Ahmed Yesevi, an influential Turkic Sufi saint who spread Sufism among the nomads. Islam also spread amongst the Uzbeks with the conversion of Uzbeg Khan. He was converted to Islam by the influence of Ibn Abdul Hamid, a Bukharan sayyid and sheikh of the Yasavi order. Uzbeg promoted Islam amongst the Golden Horde and fostered Muslim missionary work to expand across Central Asia. In the long run, Islam enabled the khan to eliminate interfactional struggles in the Horde and to stabilize state institutions.
