Many immigrants lived in the Xiongnu pasturelands, but at first they did not mix with the Xiongnu. To be a Xiongnu, one had to be a member of a clan, born of Xiongnu parents. The newcomers were well off, but were outsiders, and could marry only among themselves, not the Xiongnu. Only later did they intermix, increase in numbers, even created a state that existed from 318 to 350 AD.
Xiongnu
The ruler of the Xiongnu was called the Chanyu. Under him were the Tuqi Kings. The Tuqi King of the Left was normally the heir presumptive. Next lower in the hierarchy came more officials in pairs of left and right: the "guli", the army commanders, the great governors, the "dunghu" and the "gudu". Beneath them came the commanders of detachments of one thousand, of one hundred, and of ten men. This nation of nomads, a people on the march, was organized like an army.
