Conclusion
Three forces combined to shape the course of Central Asian history: the Turkic migrations, expansion of Islam, and the Mongol conquest. Beginning in the second century BCE, waves of Turkic migrations entered the region. It is debatable whether or not they Turkified the original Iranian inhabitants or permanently changed the ethnic makeup of the area. Turkic tribes occupied the great steppe, Turkifying the region and endowing it with a more nomadic character. They also populated the agricultural basin of Transoxiana, displacing the original Iranian inhabitants of the area. Many of these Turks slowly settled down over time. These Turkic peoples displayed a unique ability to absorb the Islamic faith and internalize the Mongol conquest.
Islam transformed the religious adherence of Central Asia and left a lasting mark on the region as well. Transoxiana gradually Islamicized, but Turkic and Persian cultures persisted. Islamization incorporated native peoples in the process of conversion. As Islam spread through the area, the faith demonstrated an extraordinary capacity to incorporate local traditions, permitting some customs to linger so long as doing so accelerated conversion. Sufi missionaries made some compromises with the Turkic nomadic culture in order to establish the religion in the area. Sufism’s inherent flexibility helped to promote conversion, and the blend of orthodox Islam and Turkic pastoral nomadism created a uniquely Central Asian brand of the faith.
The Mongol conquest of Central Asia had the most immediate impact on the history of the region. Although the Mongols eventually Turkified over time, the legacy of Genghis-Khanid legitimacy remained. Genghis Khan had developed a secure and dependable means of transferring power, for Genghis-Khanid legitimacy reduced the number of contenders vying for the throne; the Mongols did not collapse as a “nation” following the death of their founder. Genghis Khan bequeathed a legacy of political legitimacy to the region that would last until 1920.
