The End of the Mongol Empire

The mongol empire came to an end in the second half of the fourteenth century. The russian principalities were very fragmentary, but then they will unify after a threat from the mongols. They abandonded their cities and withdrew because it was too heavy for them any more. And i show in the book that in the sixteenth century they really became so different that now we talk about cassak usbek. So it's the end of this er nomedic regime. But still, there's an heritage, of course. Ok.
