### Seven Hungarians, Khabar, demographic growth
Seven Hungarians This expression was preserved by Anonymus, in the form of Hetumoger; he used it to refer to the seven chieftains of the conquering Hungarians. Based on analogies (for example, onogur = »ten onogurs«) it is certain that originally it was the name of the Hungarian tribal alliance, the political unit, which united the seven Hungarian tribes under the lead of the Magyar (Megyer) tribe. ZSA Khabar A small group of people, who joined the Hungarians before they occupied the Carpathian Basin; they are also called Khavars. Byzantine emperor, Constatntin VII's work entitled "How to Govern an Empire?" contains the only detailed report about the Khabars. According to this, some Khazars rebelled against their ruler, and after their unsuccessful revolt, their three tribes joined the Hungarians. These three tribes had a common leader. Besides their own language they also spoke Hungarian. In the event of a military campaign they were situated at the front of the army corps. In historiography, when analysing this report, all elements are doubtful, similarly there are differrent opinions concerning the future fate of the Khabars and their descendents. After the middle of the 10th century the written sources do not mention them, and their archaeological remains have not been identified either. ZSA demographic growth A sudden increase of the population of the world, or certain countries or territories. SGY
