Genghis Khan and the Making of the Modern World - Jack Weatherford [114]
The Mongols allowed each nation under its control to continue minting coins in the denominations and weight they had traditionally used, but they established a universal measure based on the sukhe, a silver ingot divided into five hundred parts, to which each of the local currencies was tied. This standardization of varied currencies relative to the sukhe eased problems in accounting and currency exchange for both merchants and government administrators. Thus, standardization of currency allowed Mongke Khan to monetize taxes, rather then accepting payment in local goods. In turn, the monetization allowed for standardized budgeting procedures for his imperial administration, since instead of accepting taxes in goods, the Mongols increasingly accepted them in money. Rather than relying on government officials to collect and reallocate tribute of grain, arrows, silk, fur, oil, and other commodities, the government increasingly moved money rather than goods. For the first time, a standardized unit of account could be used from China to Persia. So long as the Mongols maintained control of money, they could let merchants assume responsibility for the movement of goods without any loss of government power.
In Karakorum in the spring of 1253, with the finances of the empire on solid footing, Mongke summoned his siblings and close family to a small khuriltai to plan their new policies and undertakings. Now that they exercised firm control over the core of the Mongol Empire, what should they do with it? The families of two of Genghis Khan’s sons, Ogodei and Chaghatai, had been crushed and deprived of most of their holdings. The third branch, the descendants of Jochi, with whom Sorkhokhtani had made her effective alliance, had been in effect granted their independence to rule over Russia and the European territories as they saw fit. Mongke Khan was ready to resume the expansion of the Mongol Empire, but he sought to do so in a way that primarily benefited himself and his brothers rather than the many cousins, the other grandchildren of Genghis Khan.
Despite his fondness for European contraptions and design, Mongke showed no interest in launching another campaign in that direction. He returned to the dual campaigns of Genghis Khan against the Sung dynasty of South China and the Muslim civilization of the Arabs and Persians. Mongke assigned Hulegu, the brother with the best military training, to take the Army of the Right with the plan to attack the Arab cities of Baghdad, Damascus, and Cairo. Mongke assigned Khubilai, who despite his lack of military experience had a deep knowledge of Chinese culture, to lead the Army of the Left to conquer the Sung dynasty. As Great Khan, Mongke remained at the center in Mongolia, while Arik Boke, their youngest brother and therefore the Prince of the Hearth for their family, stayed behind to assist him in managing the empire. In May 1253, Hulegu and Khubilai headed off to complete the two conquests ordered by their grandfather and now reaffirmed by their eldest brother.
In the customary Mongol preparation for invasion, Hulegu had already dispatched advance troops across central Asia to clear the path of all herds in order to ensure a good supply of pasture when the main army passed through the area. Hulegu allowed his vanguard to probe enemy forces and initiate diplomatic negotiations with potential allies before the threat of his massive army appeared. The main army gathered in the summer to fatten their horses, and in traditional Mongol style would campaign only in winter. Unlike Genghis Khan’s warriors, who moved with lightning speed and approached the Muslim
