Around 830, a rebellion breaks out in the Khazar khaganate.
As a result, three Kabar tribes of the Khazars join the Hungarians and move to what the Hungarians call the Etelköz in the southern Russian steppe.
The Hungarians faced their first attack by the Pechenegs around 854, though other sources state that an attack by Pechenegs was the reason for their departure to Etelköz.
The new neighbors of the Hungarians are the Varangians and the eastern Slavs.
From 862 onwards, the Hungarians (already referred to as the Ungri) along with their allies, the Kabars, start a series of looting raids from the Etelköz into the Carpathian Basin, mostly against the Eastern Frankish Empire (Germany) and Great Moravia, but also against the Balaton principality and Bulgaria.
