As he smashed the feudal system of aristocratic privilege and birth, he built a new and unique system based on individual merit, loyalty, and achievement. He took the disjointed and languorous trading towns ... and organized them into history’s largest free-trade zone. He lowered taxes for everyone, and abolished them altogether for doctors, teachers, priests, and educational institutions. He established a regular census and created the first international postal system. His was not an empire that hoarded wealth and treasure; instead, he widely distributed the goods acquired in combat so that they could make their way back into commercial circulation. He created an international law and recognized the ultimate supreme law of the Eternal Blue Sky over all people. At a time when most rulers considered themselves to be above the law, ... insisted on laws holding rulers as equally accountable as the lowest herder. He granted religious freedom within his realms, though he demanded total loyalty from conquered subjects of all religions. He insisted on the rule of law and abolished torture, but he mounted major campaigns to seek out and kill raiding bandits and terrorist assassins. He refused to hold hostages and, instead, instituted the novel practice of granting diplomatic immunity for all ambassadors and envoys, including those from hostile nations with whom he was at war.
