Chizhishizhuhou Chanyu
The southern Xiongnu were a branch of the eastern Xiongnu that followed the rebellious pretender Huhanye and in 51-53 BC moved en masse within the Han borders under protection of Chinese. Since the times of Huhanye, the status of the southern Xiongnu was loyal allies of the Han Dynasty. The southern Xiongnu enjoyed material support of the old "heqin" treaty, and in return guarded the Chinese northern borders and participated in the Chinese external and internecine conflicts as long as the Chinese court respected their independence. However, when the Han imperial court attempted to appoint an ineligible for the crown Western Jükü-Prince Yufuluo from ineligible Right Wing as a Chanyu, instead of respecting the traditional election, the southern Xiongnu dissented and elected a lawful alternate Hyuibu Gudu-heu. Later they expelled Yufuluo, who had to seek safety in exile at the Han imperial court.
Economic history of China before 1912
In 304, there was a massive uprising of barbarian clans that were under Chinese control. Following several years of civil war between the various princes of the Jin dynasty, the Xiongnu, led by Liu Yuan, revolted and declared their independence from China. Several other groups under Chinese control subsequently revolted, including the Jie, Qiang, Di, and Xianbei. These groups became collectively known as the Wu Hu, committing genocide against Han Chinese in the Yellow River valley. The collapse of the Jin Empire quickly followed these revolts. The Wu Hu invasion caused large-scale depopulation and the market economy that developed during the Qin, Han, Wei and Jin to decline rapidly, allowing the feudal manorial economy returned to prominence. Large manorial estates were self-sufficient and isolated from the wider market. These estates were self-contained economies that practised agriculture, herding, forestry, fishing, and the production of handicraft goods. Exchange was no longer carried out through money, but barter. Following the economic revival after the unification of the Sui, the manorial economy again declined.
