Hoelun in the context of "Olkhonud"

The Khongirad (/ˈkɒŋɡɪræd/; Mongolian: ᠬᠣᠩᠭᠢᠷᠠᠳ Хонгирад; Kazakh: Қоңырат, romanized: Qoñyrat; Chinese: 弘吉剌; pinyin: Hóngjílá) was one of the major divisions of the Mongol tribes. 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.

During the Yuan dynasty they were given the title Lu Wang ("Prince of Lu"; Chinese: 鲁王), and a few Khongirads migrated west into the territory of modern Uzbekistan and Turkistan Region where they became governors of Khwarazm and were known as the Sufi dynasty. After a brief period as independent rulers, they were subjected by Timur.

Behter or Bekter (Mongolian: Бэхтэр; died 1180) was the son of Yesugei, chief of the Khamag Mongol, and a junior wife named Sochigel or Suchigu in some sources and Ko'agjin in others. He was also a half-brother of Genghis Khan, then known as Temujin. On the death of Yesugei, Temujin, his mother Hoelun, his siblings and two half-brothers (including Behter, Belgutei and their mother Sochigel) were abandoned by their tribe and left to fend for themselves. Living off the land, they managed to survive. However, the older half-brothers deprived 14-year-old Temujin and his brother Qasar of their spoils. Temujin and Qasar stalked and killed Behter, for which they were scolded by their mother Hoelun.

Hachiun (Mongolian: Хачиун, also known as Hachiun Alchi Mongolian: Хачиун Алчи, Qachi'un, Qachi'un-elchi; born c. 1166) was a full-brother of Genghis Khan and the third child of Yesugei and Hoelun. The Secret History of the Mongols specifies that "when Temujin was 9 years old, Hachiun was five years old." As a child he received a prefix "Alchi" to his name and therefore was referred to as Hachiun-alchi, or Alchidai (diminutive form of "Alchi"). He probably had a son whose name was Ilchidey (Iljigdei).

If other brothers of Temujin, Hasar and Temuge, are frequently mentioned in the Secret History as devoted companions and supporters of the elder brother, the mentions of Hachiun are rare, not only in the accounts of political and public affairs, but also in regular dialogues of daily life. Therefore, there is an opinion that Hachiun might have died early as the chronicles describing the later affairs of Genghis Khan do not mention Hachiun. But he was still alive in 1207: when already a full-fledged ruler of the whole of Mongolia, Genghis Khan was arranging his state affairs, Hachiun received land possessions and subjects from his mighty elder brother the seventh in the hierarchy after their mother Hoelun and younger brother Temuge (as one household), 4 sons of Temujin and brother Hasar, in that order.
