The Onogur state became an Avar-Bulgar federation and spanned large areas of eastern Europe, extending from Pannonia to the Kuban in the 7th century.
Out of the turmoil, Asparukh (apparently the brother of the Khagan) emerged as the most prominent figure, leading his Bulgars out of the federation and south across the Danube to establish his state of Bulgaria there.
Little is known of what happened within Avar Onoguri between 685 and 791, but it is certain that reference to the area as Onoguria or Hungary continued among their western neighbours until the name stuck.
