The Kabars (Greek: Κάβαροι), also known as Qavars (Qabars)[1] or Khavars[2] were Bulgar Turks of Khazaria. Some joined the Magyar confederation in the 9th century while others joined the Rus' Khaganate.


The Byzantine Emperor Constantine VII is the principal source of the Kabars' history.[3][4] He dedicated a whole chapter—chapter 39—to the Kabars (or Kabaroi) in his De Administrando Imperio,[4] which was completed around 950. The Emperor described the Kabars as "a race of Khazars" who had risen up against the Khagan.[4] The uprising was crushed, and some of them were massacred, but others escaped and joined the Magyars in the Pontic steppes.[4]
