From the late fifth century and the first half of the sixth century on, Turks infiltrated the northern parts of Central Asia and became neighbors with Iran. At the time of Khosrow Anushirvan, the Turks reached the area beyond the Syr Darya, but stopped there. In the time of Parviz, wars between Iran and Turks led to the defeat of the Turks. The Turks during the Sassanid era enjoyed the support of the Roman Empire (Byzantium). During the Abbasids, the Turks slowly entered the Abbasid apparatus due to the support they received. Mo'thasim, son of Ma'mun, whose mother was a Turk, provided a platform for the infiltration of the Turks. During the Samanids, the Turks served the Samanid emirs. However, the Syr Darya River was an obstacle to the arrival of the Turks and the Ghuzz, and the city of Utrar (Faraab) was one of the major fortifications to prevent the Turks from penetrating.
