History of the Huns
The history of the Huns spans the time from before their first secure recorded appearance in Europe around 370 AD to after the disintegration of their empire around 469. The Huns likely entered Western Asia shortly before 370 from Central Asia: they first conquered the Goths and the Alans, pushing a number of tribes to seek refuge within the Roman Empire. In the following years, the Huns conquered most of the Germanic and Scythian tribes outside of the borders of the Roman Empire. They also launched invasions of both the Asian provinces of Rome and the Sasanian Empire in 375. Under Uldin, the first Hunnic ruler named in contemporary sources, the Huns launched a first unsuccessful large-scale raid into the Eastern Roman Empire in Europe in 408.
