The conquest of Central Asia and Transcaucasia by the Mongol-Tatars?
middle Asia
From 1219 to 1221, the army of Genghis Khan wiped out a huge number of cities and villages from the earth. The rich and agricultural territories of Semirechye became almost a desert. The irrigation system was destroyed. The conquerors destroyed the population, left only artisans, and even those were taken prisoner and sent to Mongolia.
Transcaucasia
After the death of Genghis Khan, the campaigns of conquest did not stop. The eyes were laid on the Transcaucasia. The Mongols destroyed cities on their way, killed people, left some alive and sent them into slavery. Everything continued as before with destructive force. But a huge part of the North Caucasus was under the protection of the Golden Horde. For many years Transcaucasia was the territory of litigation between the Khulagids and the Golden Horde.
