“Unlike the masters of other great empires, the Mongols contributed little to the civilizations that came after them. They adopted the cultures of their subjects and when their empire disintegrated the world forgot them, but they had altered the course of history and they had left it scarred. Russia was torn away from Europe, and when the Mongols abandoned it after two hundred years it was feudal and backward. Poland and Hungary were so devastated that they never emerged to play their part in the renaissance that followed in the west. Bulgaria, like Russia, was isolated and then fell to the Ottoman Turks, whom the Mongols had driven out of Khwarizm and who were one day to stand on the banks of the Danube as the Mongols had done. The lands that once nurtured the great civilizations of the Persians were returned to the desert and they have never recovered. Wherever the Mongols rode they left an irretrievably ruined economy and wherever they ruled they left a petty, self-important aristocracy and an exploited peasantry.” – James Chambers, The Devil’s Horsemen
