The modern Uzbek language is largely derived from the Chagatai language which gained prominence in the Timurid Empire. The position of Chagatai (and later Uzbek) was further strengthened after the fall of the Timurids and the rise of the Shaybanid Uzbek Khaqanate that finally shaped the Turkic language and identity of modern Uzbeks, while the unique grammatical and phonetical features of the Uzbek language as well as the modern Uzbek culture reflect the more ancient Iranian roots of the Uzbek people.
