[6] Imre Boba and Pavel Georgiev write, the name is connected the Latin word for spoil (praeda), showing that the inhabitants of the Carolingian Empire regarded the Praedenecenti as plunderers.
[14][15] Their prolonged conflicts with the Bulgars and their attempts to seek assistance from the Franks imply that they inhabited a wide region between Bulgaria and the Carolingian Empire.
[1] Georgiev emphasizes, the Carolingian chronicles also referred to the land between the Tisza and the Danube when writing of Dacia, thus the Praedenecenti may have also controlled this region.
[17] Avars and other peoples from the Eurasian steppes who were subjected to them inhabited the wider region of the Tisza river till the end of the 8th century.
[20][21] An Avar dignitary, the kapkhan, went to the Carolingian Empire in early 805, asking Charlemagne to grant a territory to his people, because they "could not stay in their previous dwelling places on account of the attacks of the Slavs",[22] according to the Royal Frankis Annals.
[23] The report shows that new power centers, led by Slavic warlords, emerged along the Middle Danube shortly after the collapse of the khaganate.
[1] At Frankfurt [Louis the Pious] convoked a general assembly, and with the magnates whom he had ordered to appear there he took care, as usual, of all that pertained to the welfare of the eastern parts of his kingdom.
At this assembly he received embassies and presents from all the East Slavs,[a] that is the [Abodriti], Sorbs, Wilzi, Bohemians, Moravians, and Praedenecenti, and from the Avars living in Pannonia.Their envoys returned to the empire in 824.
[2] [Louis the Pious] also received the envoys of the [Abodriti] who are commonly called Praedenecenti and live in Dacia on the Danube as neighbors of the Bulgars, of whose arrival he had been informed.
[33] According to scholarly theories, they were most probably forced to accept the Bulgars' rule, although some of them may have fled to the Carolingian Empire or settled among the Avars who still dwelled in the plains of the Carpathian Basin.
