The Khongirad, also known as Qongirat (Qoñğyrat/Қоңғырат), was one of the major divisions of the Mongol tribes. Variations on the name include Onggirat, Ongirat, Qongrat, Khungirat, Kungrad, Qunghrãt, Wangjila (王紀剌), Yongjilie (雍吉烈), Qungrat, and Guangjila (廣吉剌) in Chinese sources. Their homeland was located in the vicinity of Lake Hulun in Inner Mongolia and Khalkha River in Mongolia, where they maintained close ties with the ruling dynasties of northern China. Because the various Hongirad clans never united under a single leader, the tribe never rose to great military glory. Their greatest fame comes from being the primary consort clan of the ruling house of Genghis Khan's Mongol empire. Genghis Khan's mother (Hoelun), great grandmother, and first wife were all Khongirads, as were many subsequent Mongol Empress and princesses.

Gegeen Khan, born Shidibala, also known by his temple name as the Emperor Yingzong of Yuan, was an emperor of the Yuan dynasty of China. Apart from Emperor of China, he is regarded as the ninth Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. His personal name "Shidibala" in Sanskrit means "purity protection" and his regnal name "Gegeen Khan" means "enlightened/bright khan" in the Mongolian language.
