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).
History of Tuva
The Xiongnu ruled over the area of Tuva prior to 200 AD. The identity of the ethnic core of Xiongnu has been a subject of varied hypotheses and proposals by scholars including Mongolic and Turkic. At this time a people known to the Chinese as Dingling inhabited the region. The Chinese recorded the existence of a tribe of Dingling origin named "Dubo" in the eastern Sayans. This name is recognized as being associated with the Tuvan people and is the earliest written record of them. The Xianbei defeated the Xiongnu and they in turn were defeated by the Rouran. From around the end of the 6th century, the Göktürks held dominion over Tuva up until the 8th century when the Uyghurs took over.
