Magyar Tribes
The Magyar tribes or Hungarian clans were the fundamental political units within whose framework the Hungarians (Magyars) lived, until these clans from the region of the Ural Mountains invaded the Carpathian Basin in the late 9th century (the Hungarian conquest of the Carpathian Basin) and subsequently established the Principality of Hungary.
According to András Róna-Tas the locality in which the Hungarians, the Manicha-Er group, emerged was between the Volga river and the Ural Mountains. Between the 8th and 5th centuries BC, the Magyars embarked upon their independent existence and the early period of the proto-Hungarian language began.
Around 830 AD, when Álmos, the future Grand Prince of the Hungarians, was about 10 years old, the seven related tribes (Jenő, Kér, Keszi, Kürt-Gyarmat, Megyer [hu], Nyék and Tarján) formed a confederation in Etelköz, called "Hétmagyar" ("Seven Magyars"). Their leaders, the Seven chieftains of the Magyars, besides Álmos, included Előd, Ond, Kond, Tas, Huba and Töhötöm, who took a blood oath, swearing eternal loyalty to Álmos. Presumably, the Magyar tribes consisted of 108 clans.
The confederation of the tribes was probably led by two high princes: the kende (their spiritual ruler) and the gyula (their military leader). The high princes were either elected by the leaders of the tribes or appointed by the Khagan of the Khazars who had been exerting influence over the Magyars. Around 862 AD the seven tribes separated from the Khazars.
Before 881 AD three Turkic tribes rebelled against the rule of the Khagan of the Khazars, but they were suppressed. After their defeat they left the Khazar Empire and voluntarily joined the Hétmagyar confederation. The three tribes were organised into one tribe, called Kabar, and later they played the roles of vanguard and rear guard during the joint military actions of the confederation. The joining of the three tribes to the previous seven created the On-ogur (Ten Arrows), one of the possible origins for the name Hungarian.
