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).
Huns
Recent scholarship, particularly by Hyun Jin Kim and Etienne de la Vaissière, has revived the hypothesis that the Huns and the Xiongnu are one and the same. De la Vaissière argues that ancient Chinese and Indian sources used "Xiongnu" and "Hun" to translate each other, and that the various "Iranian Huns" were similarly identified with the Xiongnu. Kim believes that the term Hun was "not primarily an ethnic group, but a political category" and argues for a fundamental political and cultural continuity between the Xiongnu and the European Huns, as well as between the Xiongnu and the "Iranian Huns".
