Great invasions from the fourth to seventh centuries

In the second and third centuries CE, the Huns began to leave the Central Asian steppes. They crossed the Danube in 377 CE and occupied Pannonia, which they used for 75 years as their base for launching looting-raids into Western Europe. However, Attila's death in 453 brought about the disappearance of the Hunnic empire. In 568, a Turko-Mongol tribal confederacy, the Avars, conducted its invasion into the Middle Danube region. The Avars occupied the lowlands of the Pannonian Plain and established an empire dominating the Carpathian Basin.

In 623, the Slavic population living in the western parts of Pannonia seceded from their empire after a revolution led by Samo, a Frankish merchant. After 626, the Avar power started a gradual decline but its reign lasted to 804.
