How did the Xiongnu move to Europe and establish Hungary after they were defeated by the Han Dynasty?

In the past, the Hungarians were identified by some scholars as the nomadic "Hongnu" recorded in ancient Chinese documents. However, there is great controversy in modern academic circles. There is no conclusive evidence that the Huns who invaded Europe were Descendants of the Huns. According to historical records from the Qin and Han dynasties, the Xiongnu were active in Northeast China and Central Asia. Their combat effectiveness and mobility are very high, giving them a military advantage, especially when fighting against highly civilized nations. Later, after the Xiongnu were repeatedly defeated during the Eastern Han Dynasty, the Northern Xiongnu, a branch of the Xiongnu, began to move westward. Some people believe that they were the Huns who entered Europe around 350 AD.

The Hungarian region was the former province of Pannoia in the Roman Empire. After the fall of the Roman Empire, various ethnic groups migrated here one after another. The first to arrive were the Huns. Under the leadership of Attila, they established a powerful Hunnic Empire, from which the name Hungary may have come.
