Straight to the point: the Xiongnu and the Turks belong to the same lineage, strictly speaking, the Xiongnu are in the front, the Turks are in the back, and the Turks are a branch of the Xiongnu.
For example, the Xiongnu are the second master of the Turks.
The Xiongnu are the common ancestors of the ancient Mongols and the Turks, and the proto-Turkic people are another species of the Xiongnu, which indicates that there is a certain similarity between the two races.
The Turkic nation was formally formed after the establishment of the Turkic Empire, while the Xiongnu lived in the desert north of the Qin and Han dynasties.
The two overlap geographically, but not exactly in time. This difference reflects the political, military, and cultural patterns of different stages of historical development and different regions.
Probably the situation was that the Xiongnu came first, and the Turks came later, because in the migration and marriage of the tribes, some people walked and walked, and their names changed.
Historically, both the Xiongnu and the Turks used war as the main means of territorial expansion.
Their territories all traverse the Eurasian continent, opening Chinese territory from the eastern borders, and fighting the Persian-speaking peoples on the western borders all year round.
In a certain historical period, the Xiongnu and the Turks had a certain phenomenon of integration.
For example, when the Turks eliminated Rouran (also belonging to Xianbei) and defeated Tuoba Xianbei, the Xiongnu who integrated into Xianbei also merged into the Turks. This phenomenon of integration may be due to geographical proximity, cultural exchanges, etc.
Both the Xiongnu and the Turks were historically important nomadic peoples who had a profound impact on the political, military, and cultural landscape of Eurasia.
Their historical trajectories reflect the lifestyle, social organization structure and cultural characteristics of the ancient nomadic peoples, as well as the mutual relations and interactions between different ethnic groups in history.
In short, the relationship between the Xiongnu and the Turks was complex and multifaceted, including ethnic relations, historical development, territory and warfare, integration phenomena, blood relations and common ancestry, and historical status and influence.
Together, these aspects constitute the uniqueness and importance of the Xiongnu and Turks in the process of historical development.
