The qualifier Mongol tribes was established as an umbrella term in the early 13th century, when Temüjin united the different tribes under his control and established the Mongol Empire. There were 19 Nirun tribes that descended from Bodonchar and 18 Darligin tribes, which were also core Mongolic tribes but not descending from Bodonchar. The unification created a new common ethnic identity as Mongols. Descendants of those clans form the Mongolian nation and other Inner Asian people.
