[2] 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.
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.
Hachiun was said to have very good relationship with his brother Hasar but a poorer one with Temüge.
This might be due to preferential treatment of his younger brother in the form of land and power.
