Pre-Timurid sources Qarachar features very little in the histories contemporary to his lifetime. In
The Secret History of the Mongols, he is mentioned alongside his father,
Suqu Sechen ("the Sage"), as having attended the assembly which proclaimed
Genghis Khan (then called Temüjin) ruler of the Mongols in 1190. Having belonged to the Mongol
Barlas tribe, the two acted as one of the delegations representing the group at the event.
The Secret History also states that in 1206, Qarachar was given
command of a thousand by the emperor. According to the thirteenth century historian
Juvayni, Qarachar later had a base in
Taloqan from which, in 1222, he marched on
Merv to suppress a rebellion. By 1227, the year that Genghis died, Qarachar and his contingent had been assigned to the retinue of Genghis Khan's second son
Chagatai, a transfer which is also mentioned in the works of
Rashid-al-Din Hamadani.
Timurid sources Later Timurid historians, such as
Sharaf ad-Din Ali Yazdi in his
Zafarnama and
Hafiz-i Abru in his
Majma and
Zubdat, greatly elaborated on the origins of the dynasty, including on the life and background of Qarachar. In such works, his ancestry (which is never clarified in earlier accounts) is said to link to that of Genghis Khan. His paternal grandfather was stated to be Erdemchu Barlas, son of Qachuli, himself a son of Tumanay Khan, Genghis Khan's great-great-grandfather. This relationship is expressed in other works as well as engraved on Timur's cenotaph and tombstone in the
Gur-e-Amir, in Samarkand, Uzbekistan. Qarachar's father Suqu Sechen was depicted as having been a trusted advisor of
Yesugei, Genghis Khan's father, having been present at the latter's birth and foretelling the infant's future greatness. Suqu is claimed by Yazdi to have died shortly after Yesugei while their children were still young, though this would contradict
The Secret History, which states that he was still alive in 1190. Qarachar was described as being among the earliest tribal leaders to swear allegiance to Genghis Khan. He was given a
command of 10,000 and advised the emperor frequently throughout his decades-long conquests. Qarachar was depicted as being consulted at critical junctures, and as having unhorsed
Ong Khan during the final battle against the
Keraites. As Genghis Khan was dying, he is recounted to have summoned his sons and brothers as well as Qarachar. There, after having received their homage, he praised the wisdom of the latter and urged his sons to follow his council and commands. Genghis Khan then ordered the division of his empire among his progeny, bestowing to his second son
Chagatai the lands of
Transoxiana, which would later become the
Chagatai Khanate. In continuation of a covenant made between their respective great-grandfathers Qachuli and
Qabul, he commended this son to Qarachar's care, who was also entrusted with the administration and armies to manage on his behalf. This arrangement was formalised by the legal adoption by the nobleman of Chagatai, whose daughter Qarachar also married, so as to establish a "bond of fatherhood and sonship". It was from this marriage that
Timur claimed descent. Yazdi records that Qarachar subsequently occupied a prominent position in the Chagatai court, performing the actual duties of ruling while the Khan revelled and hunted. This arrangement is mentioned by other Timurid historians such as Hafiz-i Abru, who states that as
generalissimo, he undertook matters of law, rule and custom. Natanzi in his
Muntakhab further relates that after Chagatai's death in 1241, Qarachar was given command of the household under his successor
Qara Hülegü. The ''Mu'izz al-Ansab
, a genealogical work from the reign of Shah Rukh, also adds that he carried out legal decisions based on the laws set out by Genghis Khan (the Yassa''). The year of his death is disputed between accounts. Hafiz-i Abru states that Qarachar survived Chagatai by only a year, with his death occurring in 640
AH (1243/44 CE). Conversely, Yazdi narrates that he had outlived the Khan by thirteen years, dying in 652 AH (1255/56 CE) at the advanced age of eighty-nine. Depending on the source, he may have had up to nineteen sons, with his descendants forming seven of the Barlas clans of
Turkestan and Transoxiana. Qarachar's position of generalissimo was bequeathed to his son
Ichil (Timur's great-great-grandfather), with the office becoming hereditary among his descendants. ==Historicity==
