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.
