Under The Bleachers, by Seymour Heinie.
Genghis Khan and the Making of the Modern World -- Jack Weatherford. Based primarily on the Secret History of the Mongols, relatively recently discovered & translated. Research for my book in progress. Did you know that once Temujen (Headlong) had united all the people who lived between felt walls, he hosted a gathering of the united hordes near God Mountain, where he was first proclaimed Chingghis Khan (Alpha-Wolf King). It was at this gathering that he first promulgated laws to govern a people who had never known any laws, only traditions. His first law was this one: no more rape. Yep... He made it a capital crime for a man to kidnap himself a bride. That put a serious crimp on your social life. Second law was no more Mongol slavery. Third, no adultery. Fourth, no more rustling. Fifth, complete religious freedom, including priests of any sort were exempt from taxes or levy. Then, a law that no one inherited their position. Instead, advancement only came by merit. At his lowest ebb, the guy was the slave of the slave of an enemy. His arms were tied to a yoke so that he could neither eat nor drink nor scratch his nose, nor even take a wizz. He was in a tent with a couple guards, awaiting probable execution for murdering his own brother. Escaped. But that just made things worse. Now he was lumbering across the prairie with his arms tied to a yoke, no place to hide, and horsemen chasing. But by the time he died, he was master of an empire more than twice the size of any other empire that has ever been. He did this with a people who never numbered more than a million, who had no inventions, no writing, no resources, no metal; no, not even so much as cloth. His army never exceeded a hundred thou. It would be like only a quarter of the Aztecs jumped on ponies & conquered from Alaska to Brazil.It's mind boggling.The last Mongol khan to rule GK's capital was finally deposed by the Soviets in 1920 -- seven hundred years years later!
