With the Uighurs Securely in His Corner Chingis was ready to launch a full-scale invasion of Xi Xia. The people of Xi Xia, known as Tanguts, founded the Xi Xia Dynasty, or “Great State of White and High,” in 1038. The Tanguts were a people of Tibeto-Burman extraction who had developed a prosperous agrarian and livestock breeding culture and occupied well-fortified towns and cities. They aspired to some level of culture and soon developed their own Writing System, based on Chinese ideograms, which they used to translate both Tibetan Buddhist texts and the Chinese Classics. While espousing Chinese culture they also practiced Tibetan-style Vajrayana Buddhism. They also maintained a large army and at their height were one of the strongest military powers in Inner Asia. Like the Uighurs they sat astride the Silk Road, controlling the vital Gansu Corridor, a narrow strip of land between the rugged mountains to the south and the inhospitable deserts to the north through which Silk Road caravans had to pass.

The intertribal warfare in Mongolia itself at the beginning of the 13th century had decimated the livestock herds of the nomads, and the early Mongol raids into Xi Xia, in 1205 and 1207, were mainly attempts to capture large amounts of livestock which were then driven back to Mongolia. These raids, however, were enough to alert the Tanguts to the danger of the nomads to the north, who like wolves swooped down on their herds, and the failure of the Xi Xia ruler at the time, Li Chunyu, to protect his domains may have led to the palace revolt which deposed him in late 1207. The new ruler Li Anguan, perhaps hoping to placate the Mongols and buy time, give Chingis one of his daughters as a bride. At the same time he strengthened the country’s defenses in anticipation of another Mongol attack. He didn’t have long to wait. Having subdued the Uighurs to the west without a battle, Chingis was now ready for a full-scale onslaught on the territory coterminous with north China plain controlled by the Jin Dynasty, his ultimate target.
In early 1209 Chingis himself led an army 650 miles south to the domains of Xi Xia, and soon captured the border town of Wulahai. The Xi Xia armies rallied, however, and a stalemate ensued until the end of summer, when reinforcements arrived from Mongolia. The Tanguts were soon driven back to their fortified cites, including their capital of Ningxia, current-day Yincheng, on the Yellow River. A weakness of the Mongols was soon revealed. Although masters of horseback warfare on the open steppe they had very little if any experience in besieging fortified cities. Having surrounded the Xi Xia capital, Chingis attempted various stratagems to capture the city, including diverting the waters of the Yellow River in an attempt to flood the city, but by the end of 1209 none of them had succeeded. In the meantime, the Xi Xia ruler had sent messengers to the Jin ruler in Zhondu (near current-day Beijing), asking for assistance against the Mongols. His advisors recommended sending an army to relieve the besieged city, arguing that if Xi Xia fell the Jin themselves would be Chingis’s next target. The emperor responded, “It is an advantage to my state if its enemies attack each other. What grounds do we have for concern?” No relief army was sent, and the Xi Xia were left the to their own devices. This proved to be a fatal miscalculation on the part of the Jin emperor.
In January of 1210 the Mongols themselves suffered a setback when the waters of the Yellow River, perhaps diverted by the Tanguts themselves, flooded their own camp. Faced with a stalemate, negotiations began between the Chingis and the Xi Xia ruler. Control of the countryside by the Mongols was a fait accompli, but Chingis offered to let the Tanguts keep control of their cities as long as they provided auxiliary troops for the Mongol army. The Xi Xia ruler declined, pointing out that “We are a nation of town-dwellers. We would not be in a state to fight as auxiliaries in the event of a long march followed by a heated battle.” He did offer to provide the Mongols with herds of camels and other livestock, trained falcons, wool garments, silk cloth, and as a final sweetener another one of his delectable daughters as a bride for Chingis himself. Although the Tanguts were allowed to remain as figureheads in their own country, most of their territories were now effectively controlled by the Mongols. For the moment Chingis was satisfied with the outcome, but he would never forgive the Tanguts for refusing to provide him with troops. Before he died he would return to Xi Xia and exact a terrible revenge.
The defeat of the Xi Xia served a number of purposes; the campaign had been good training for the upcoming war with the much for stronger Jin Dynasty, Chingis’s ultimate target, and it had revealed weaknesses in the Mongol army, namely their ignorance of siege techniques, which would have to be corrected before any further campaigns against fortified cities. A springboard for the invasion of the Jin Dynasty domains from the west had been secured, and the Mongols now controlled the Gansu Corridor, the bottleneck through which most of the caravan routes which originated in Xian and other Silk Road terminuses had to pass. The Mongols now sat astride the Silk Road from the boundaries of the Jin Dynasty domains in the east to the western edge of Uighuristan in the Tarim Basin. The road has been cleared for Chingis’s attack on the Jin Dynasty, the current rulers of northern China, still considered the richest source of plunder and the ultimate prize by the nomads from the Mongolian Plateau to the north.
