They developed the census? Gee isn't that great because practically everywhere they took over the populations were eliminated by at least half, I guess they made it easier to count. Seriously what is wrong with people. The Mongols slayed every living inhabitant of cities that dared to be located in areas which resisted them. One of the greatest civilizations ever, the Persians, were practically wiped off the face of the planet. They need a new word besides 'genocide' to describe the massive slaughter they perpetuated on the peoples of Eurasia. You give them credit for "creating" a nation? How did they 'create it', exactly, by cutting its population to 60 million? By wiping out any traces of old Chinese dynasties? Did they 'help' the Middle East by setting back their food supply systems by centuries? Does the fact that they destroyed some of the the greatest cities in the world - Baghdad, Kiev, Herat, Nishapur, Samarkand, get absolved because they lowered taxes and supposedly invented a postal system?
They had religious freedom? Fantastic. Tell me what good that is when churches mosques, and libraries are burnt down. When literature and sacred landmarks are destroyed.
