The Hunnic empire was formed under the reign of Attila, centered in present-day Hungary; its territory included parts of Germany, the Balkans, and Ukraine. It bordered the Eastern Roman Empire to the southeast and the Western Roman Empire to the west and southwest; its other boundaries are uncertain. The empire dissolved after Attila's death in 453 as a result of struggles over succession and leadership, finally disappearing around 469.

The origins of the Huns that swept through Europe during the 4th Century remain unclear; they may have been connected with the Xiongnu and the later Northern Xiongnu, defeated and dispersed by China some three centuries before. However, most mainstream historians consider them as a group of nomadic tribes from Central Asia with mixed origin.^{[citation needed]} There was a Hunnic language, and Gothic seems also to have been used as a lingua franca.

European accounts first mention the Huns in the lands north-west of the Caspian Sea about 370, when they conquered a tribe of Alans to their west. Pushing further westward, the Huns subjugated many Ostrogoths. In 395, a Hun raid across the Caucasus mountains devastated Armenia, then captured Erzurum, besieged Edessa and Antioch, and even reached Tyre.
