Uralic-speaking peoples who were living in the central and southern regions of the Urals split up. Some dispersed towards the west and northwest and came into contact with Turkic and Iranian speakers who were spreading northwards. From at least 2000 BC onwards, the Ugric-speakers became distinguished from the rest of the Uralic community, of which the ancestors of the Magyars, being located farther south, were the most numerous. Judging by evidence from burial mounds and settlement sites, they interacted with the Indo-Iranian Andronovo culture and Baikal-Altai Asian cultures. 4th century to c. 830 In the 4th and 5th centuries AD, the Hungarians moved to the west of the Ural Mountains, to the area between the southern Ural Mountains and the Volga River, known as Bashkiria (Bashkortostan) and Perm Krai. In the early 8th century, some of the Hungarians moved to the Don River, to an area between the Volga, Don and the Seversky Donets rivers. Meanwhile, the descendants of those Hungarians who stayed in Bashkiria remained there as late as 1241. The Hungarians around the Don River were subordinates of the Khazar Khaganate. Their neighbours were the archaeological Saltov culture, i.e. Bulgars (Proto-Bulgarians, Onogurs) and the Alans, from whom they learned gardening, elements of cattle breeding and of agriculture. Tradition holds that the Hungarians were organized in a confederacy of seven tribes. The names of the seven tribes were: Jenő, Kér, Keszi, Kürt-Gyarmat, Megyer, Nyék, and Tarján. c. 830 to c. 895 Around 830, a rebellion broke out in the Khazar khaganate. As a result, three Kabar tribes of the Khazars joined the Hungarians and moved to what the Hungarians call the Etelköz, the territory between the Carpathians and the Dnieper River. The Hungarians faced their first attack by the Pechenegs around 854. The new neighbours of the Hungarians were the Varangians and the eastern Slavs. From 862 onwards, the Hungarians (already referred to as the Ungri) along with their allies, the Kabars, started 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. Entering the Carpathian Basin (c. 895) In 895/896, under the leadership of Árpád, some Hungarians crossed the Carpathians and entered the Carpathian Basin. The tribe called Megyer was the leading tribe of the Hungarian alliance that conquered the centre of the basin. At the same time
