The gradual decline of Avar power accelerated to a rapid fall within a decade.
A series of Frankish campaigns in the 790s, beginning in 791, ended with the conquest of the Avar realm after eight years.
The 791 campaign ended successfully, although no pitched battle was fought.
Avars had fled before the Carolingian army arriving by the Danube, while disease left most of the Avar horses dead.
Tribal infighting began, showing the weakness of the khaganate.
The Franks had been supported by Slavs, who established polities on former Avar territory.
One of Charlemagne's sons captured a large, fortified encampment known as "the Ring", which contained much of the spoils from earlier Avar campaigns.
The campaign against the Avars
again gathered momentum.
It would take two massive hammer-blows, two major musters of the host, drawing upon levies from every part of the now great kingdom, before the robbers'
nest was exterminated.
And at last, in the year 796, five years after the war began, the Avars cracked and lay utterly at the king's mercy.

By 796, the Avar chieftains had surrendered and accepted Christianity.
Pannonia was conquered.
According to the Annales Regni Francorum, Avars began to submit to the Franks from 796 onwards.
The song "De Pippini regis Victoria Avarica" celebrating the defeat of the Avars at the hands of Pepin of Italy in 796 still survives.
The Franks baptized many Avars and integrated them into the Frankish Empire.
A growing amount of archaeological evidence in Transdanubia also suggests an Avar population in the Carpathian Basin in the very late 9th century.
In 799, some Avars revolted.

In 804, the Bulgaria conquered the southeastern Avar lands of Transylvania and southeastern Pannonia up to the Middle Danube River, and many Avars became subjects of the Bulgarian Empire.
Khagan Theodorus, a convert to Christianity, died after asking Charlemagne for help in 805; he was succeeded by Khagan Abraham, who was baptized as the new Frankish client (and should not be assumed from his name alone to have been Khavar rather than Pseudo-Avar).
Abraham was succeeded by Khagan (or Tudun) Isaac (Latin Canizauci),  about whom little is known.
The Franks turned the Avar lands under their control into a military march.
The March of Pannonia—the eastern half of the Avar March—was then granted to the Slavic Prince Pribina, who established the Balaton principality in 840.
It continued to exist in the west until it was divided between the Carinthian and Eastern marches in 871.

Whatever was left of Avar power was effectively ended when the Bulgars expanded their territory into the central and eastern portions of traditional Avar lands around 829.
According to Pohl, an Avar presence in Pannonia is certain in 871, but thereafter the name is no longer used by chroniclers.
Pohl wrote, "It simply proved impossible to keep up an Avar identity after Avar institutions and the high claims of their tradition had failed".
Although, Regino wrote about them at the year of 889.
The growing number of archaeological evidence in Transdanubia also presumes an Avar population in the Carpathian Basin in the very late 9th century.
Archaeological findings suggest a substantial, late Avar presence on the Great Hungarian Plain, however it is difficult to determine their proper chronology.
The preliminary results of the new excavations also imply that the known and largely accepted theory of the destruction of the Avar settlement area is outdated, the disastrous depopulation of the Avar Khaganate has never happened.

Byzantine records, including the "Notitia episcopatuumî", the "Additio patriarchicorum thronorumî" by Neilos Doxopatres, the "Chronica" by Petrus Alexandrinus and the "Notitia patriarchatuum" mention the 9th century Avars as an existing Christian population.
The Avars had already been mixing with the more numerous Slavs for generations, and they later came under the rule of external polities, such as the Franks, Bulgaria, and Great Moravia.
