The string of Silk Route kingdoms of Genghis Khan’s daughters depended on controlling the points of contact and the direction of movement rather than occupying large areas of land. Gradually the Mongols developed a system of investment similar to those in modern corporations. Thus Alaqai Beki in China had shares of animals in Iraq and furs from her sister Checheyigen in Siberia; Al-Altun had claim on part of the silk production of China, and they all received wine from the Uighur oases of Al-Altun.
During the lifetime of Genghis Khan and his daughters, the Mongol enterprise was not so much an empire as a vast global corporation in which each son and daughter had the assignment to manage one part that provided a particular set of goods. The daughters operated a world financial organization that benefited almost everyone it touched. Through this interlocking set of kingdoms ruled by the daughters of Genghis Khan, the Mongols created a new world system based on a faster flow of goods and information than had been previously practical.
The Silk Route had grown slowly over several thousand years; yet suddenly, under the administration of Genghis Khan’s daughters, it attained a level of complexity and global importance far beyond that of any earlier era. Alaqai Beki and her sisters transformed the chain of competing city-states and nations spread across Asia into an interlocking set of political and commercial units with a new specialization of labor that made them mutually interdependent rather than rivals. Under the control of the Mongol queens, the Silk Route reached its zenith.
In this extensive commercial system, each daughter’s kingdom had its own particular role. Al-Altun’s Uighurs operated the communications center of the Mongol Empire. Their location between China to the east, Mongolia to the north, and the Muslims to the southwest put them in the geographic center of the extensive Mongolian postal relay system that united the empire and made possible the rapid dispatch of messages throughout its length and breadth. The Uighurs did not serve as riders in the system; instead, they worked as translators, scribes, and clerks. From this specialization they became important in information gathering and general intelligence for the Mongol authorities.
Genghis Khan did not permit military information to be written down; it had to be delivered orally. Thus the messengers had to learn to compose and recite military orders through “rhetorically ornate rhyming words and cryptic expressions.” Occasionally the people receiving an order might not understand it, but the messenger could interpret it. This special form of military poetry served the most strategic type of communication, but for more mundane affairs, the government used the Mongolian language written in Uighur script. Under the Uighur influence, the Mongols began a steep intellectual ascent. The Uighurs already had extensive libraries of hand-copied manuscripts translated from Sanskrit, but under the Mongols many Tibetan manuscripts were also translated into Uighur.
Uighur script became the Mongol script and thereby the official script of the empire. For the next seven centuries, until 1911, it remained the official script in its Mongol and Manchu forms. Even during the Ming Dynasty, which favored Chinese writing, the Chinese court had to use Mongol script for communication with many parts of its empire and foreign nations as far away as Turkey.
When Genghis Khan left on his campaign against the Muslims, he had taken Alaqai Beki’s stepson Boyaohe with him as part of his personal detachment. The boy was ten or twelve years old when he set out with the army, and subsequently grew up on the campaign in Central Asia, where he performed very well and grew into an excellent soldier. By the time the Mongols conquered Muslim Central Asia and the army returned to Mongolia, Alaqai’s husband, Jingue, had died. In 1225, Genghis Khan then gave the precocious Boyaohe to Alaqai to be either her third or her fourth husband. At the time of his marriage to his stepmother (who was, of course, also his sister-in-law), Boyaohe was seventeen years old, and Alaqai was in her mid-to-late thirties.
