The dynasty, which evolved from Genghis Khan's own Borjigin tribe, ruled the Mongol Empire and its successor states.
The "Chinggisid principle"—that only descendants of Genghis Khan and Börte could be legitimate rulers of the Mongol or post-Mongol world—would be an important concept for centuries, until the fall of Khiva and Bukhara, the last states ruled by Chinggisid monarchs, in 1920.
[3] By the time that Genghis established the Mongol Empire in 1206, the only remaining Borjigit were the descendants of Yesügei.
Of these, the descendants of Genghis and his first, primary wife Börte held the highest seniority; the Chinggisid Principle was that this particular lineage—the eponymous Chinggisids—were the only legitimate rulers.
[5] Mongol religious ideology held that the Chinggisids would eventually become rulers of the entire world.
