For the Kereyid, Temujin was, like his father and all men of his Borijin clan, just one more Mongol vassal to be sent out to war when needed and consigned to perform the tasks that were too dangerous or boring. Temujin thought that through his extreme loyalty and his success in battle, he would gain the favor of his overlords.
Traditionally among the steppe nomads, related lineages united to form a clan, and, in turn, several clans united to form a tribe such as the Tatars or the Kereyid, or even a confederacy of tribes such as the Naiman. Although contracting or expanding over time, these unions lasted for generations and sometimes centuries. The Mongols repeatedly sought to unite into a tribe under one khan, but the union always failed. The Mongols were not so much a tribe as a roving set of fractious clans sharing the same language and culture but often fighting one another. Even within the same clan, families often feuded, broke away, and joined rival clans or enemy tribes.
Temujin’s mother was not a Mongol, and his connection to her gave him a perceived opportunity to rise up in the steppe world by negotiating a formal marriage alliance with his mother’s family in the Khongirad clan. Around 1184, when he was about twenty-two years old, Temujin arranged a marriage for Temulun, his only sister, with Botu of the Ikires. Such a marriage alliance would strengthen the tie between the two clans in the traditional way and showed Temujin’s desire to maintain permanent marital alliances, known as
Before the marriage, Botu “came as a son-in-law,” meaning that he came to live with the bride’s family as a form of service to them. According to steppe tradition, a potential groom or engaged boy resided with the family of his intended wife. Similarly, Temujin had been given at age eight to the family of his future wife, Borte, with the expectation that he would learn their ways of doing things, live under their supervision, and care for their animals. The boy had to prove himself as a capable herder, and after learning the basics as a child among his own family, he became an adult man under the watchful eye of his bride’s parents. If the boy proved lazy or unsatisfactory, the family sent him away. If he could not endure the hard work and discipline imposed by his potential father-and mother-in-law, he might run away. If they developed a working relationship, the marriage between the engaged youths would evolve and blossom in its own natural time.
Bride service could sometimes be shortened, or occasionally avoided entirely, if the boy’s family offered animals, usually horses, to the bride’s family. Temujin and his future brother-in-law operated from different premises in arranging the marriage, which became apparent during a casual conversation with another man of Botu’s family. Temujin sought to know more about his future brother-in-law by asking how many horses Botu owned. The man took the question as an opening for a horse negotiation for the marriage in place of service to the bride’s family. He responded that Botu owned thirty horses and that he would give Genghis Khan fifteen of them in exchange for Temulun.
The offer of horses for his sister outraged Temujin, though not entirely for her sake. It showed that the prospective groom did not perceive Temujin as a worthy ally, but merely as a savage Mongol trying to sell his sister for some horses.
“If one is concluding a marriage and discusses value,” Temujin angrily responded, “then one is acting like a merchant.” Temujin commenced to lecture the man: “The ancients had a saying: ‘Unity of purpose is a fortune in affliction.’” He then applied that proverb to the current situation. “If you, the people of the Ikires, follow Botu and serve me faithfully, that will suffice.” Service always outranked wealth; loyalty always outranked payments. Despite the heated exchange between the young men, the marriage was arranged, possibly through the intercession of Hoelun and her connection to the groom’s family.
With this early negotiation, the young Temujin articulated a firm principle, which he followed throughout his life when dealing with the women of his family: Women could never be traded for animals or property. Once he came to power, he made this personal affirmation into law.
