How did the Mongol conquest affect the development of Central Asia?

The Mongol conquest of Central Asia dates back to the 1220s, that is, the last years of Genghis Khan’s life. The influence of the Mongol-Tatar conquest was negative, since the population decreased, especially the urban population due to devastation, crafts and trade fell into decay, some states disappeared and new ones appeared: the Hulagu and Chagatai uluses, and later the Kazakh Khanate.

However, in the XIV-XV centuries, there was progress under one of the Genghisids – Tamerlane and his descendants. For example, in Samarkand, even Ulugbek’s observatory appeared.
