Prior to the Hungarian conquest of the Carpathian Basin in 895/6 and while they lived on the steppes of Eastern Europe east of the Carpathian Mountains, written sources called the Magyars "Hungarians", specifically: "Ungri" by Georgius Monachus in 837, "Ungri" by "Annales Bertiniani" in 862, and "Ungari" by the "Annales ex Annalibus Iuvavensibus" in 881. The Magyars/Hungarians probably belonged to the Onogur tribal alliance, and it is possible that they became its ethnic majority. In the Early Middle Ages, the Hungarians had many names, including "Węgrzy" (Polish), "Ungherese" (Italian), "Ungar" (German), and "Hungarus". The "H-" prefix is a later addition of Medieval Latin.
