Read the extract of book "The Nomads" by Ilyas Yesenberlin

Genghiz Khan had four sons: Jutchi, Jagatai, Ughedei and Tuleh. Already during his lifetime he divided among them the conquered lands and each one governed his ulus. The Empire’s central part, that is Mongolia and Northern China, belonged to the Great Genghiz Khan. Ughedei’s ulus spread towards sunset, including the lands north and west of the Altai Mountains the center of the ulus being the Chuguchaka area. The third part was the ulus of Jagatai which included the eastern areas of Central Asia as far as the Amu-Darya. The ulus’ center was the city of Almalyk. Iran, Iraq and Transcaucasia were part of the ulus of Tuleh and his son Khulagu with the center in Tebriz. The last fifth part of the empire was in possession of the eldest son Jutchi and constituted an ulus which included all the lands «where the hooves of the Mongol horses could reach», from the Kipchak steppe and as far as the Danube valley. Until the death of Jutchi the ulus’ center was the area adjoining the Ulytau Mountain and later the city of Sarai in he Lower Yedil, or Volga.
