This article is seeking to discuss about Maria Subtelny’s book “Timurids in Transition: TurkoPersian Politics and Acculturation in Medieval Iran” talks about the Turko-Mongolian and Persian state administration in the 14-15 centuries Central Asia. The founder of the great Timurid dynasty Amir Timur established a legitimate empire with Turko-Mongolian yasa rules to a sedentary form of government with Persian-Islamic features. The transition required an enormous effort from Timur to transform a nomadic empire into a centralized, sedentary state. In doing so Timur accomplished to build a great empire with splendid cities and great hydraulic construction. His descendants, especially, Sultan Husayn Bayqara retained many features of their Turko-Mongolian cultural identity and PersoIslamic administration. Prominent statesman Alisher Navai’s pivotal role during Sultan Husayn Bayqara’s reign is an important part of the literary environment of the 15th century Herat.
