The Avar Khaganate was a khanate established in the Pannonian Basin region in 567 by the Avars, a nomadic people of uncertain origins and ethno-linguistic affiliation. As the Göktürk Empire expanded westwards, the Khagan Bayan I led a group of Avars and Bulgars out of their reach, eventually settling around 568 in what used to be the Roman province of Pannonia.
