The Ülüş system was the administrative system of the historical Turkic and Mongolic states. The noun Üleş in Turkish means "share" and the verb "üleş-mek" means to share.Dictionary of Turkish language AssociationDictionary
The system According to historian Halil İnalcık, the sovereignty didn't belong solely to the khagan (emperor), but to the members of the khagan's family. İnalcık page p.218 Thus the khagan allocated each member of the family a share of the country. This share was called ülüş. According to Kürşat Kocak however, the ülüş practice included also high level state officials. Academia periodical This resembles the fief system in Medieval Europe. It is stressed by Lev Gumilev that it was not a European type feudalism, but the system was developed by the Southern Xiongnu during the second century AD.L. N. Gümilev, Eski Türkler, translation by Ahsen Batur, p. 80-81 It was used by the First Turkic Khaganate, Uyghur Khaganate, Mongol Empire and other political powers of Central Asia.
