Architecture of Mongolia
The Xiongnu confederation ruled present-day Mongolia from the third century BCE through the first century CE, living in portable, round tents on carts and round yurts. The Xiongnu aristocracy lived in small palaces, and their villages were protected by huge walls. S. I. Rudenko also mentions capital construction built of logs. Archaeological excavations indicate that the Xiongnu had towns; their chief city was Luut Hot (Dragon City).
Five Barbarians
In the 190s CE the Southern Xiongnu revolted against attempts of the Chinese Court to appoint a puppet Southern Shanyu against their will:
The Southern Xiongnu then elected a Shanyu from the Xubu in 188 CE and Chizhishizhuhou Chanyu (188–195 CE) fled back to the Chinese court. After the death of the new Shanyu in 196 CE, most of the Southern Xiongnu left to join the Northern Xiongnu and only five tribes remained in China.
