Temujin proclaimed Genghis Khan at the Onon

1206

At a great kurultai on the Onon River, the assembled Mongol tribes hailed Temujin as Chinggis, universal ruler. He abolished tribal distinctions, organized his followers into decimal units of ten, and set in motion the largest contiguous empire the world would ever see. His great yasa, a code of laws covering everything from adultery to water rights, bound the horde into a disciplined nation.
