HOMO SAPIENS III (14)
The beginning of the 13th century was marked by the invasions of the Tatar-Mongols' hordes under the leadership of Genghis Khan. Central Asia was conquered from the Indus to the Caspian Sea. The inhabitants of the cities taken by storm, left after a horrific massacre, were driven out into the field, divided among the soldiers, who turned them into slavery. The prisoners were used in the siege of cities.
