With a swift and sudden fury, Genghis—then about forty-four years old—rode onto the pages of history, leaving an indelible mark in the twenty-one years that remained for him. The reasons behind his conquest of such a large empire are not clear, but it seems as though he simply started going and never stopped. The Mongols were extraordinarily fierce warriors who struck terror in the hearts of their victims, a terror that was justified by the heaps of corpses they left behind them. It simply did not occur to Genghis to let people live: in his mind, leaving survivors would require him to devote troops to overseeing them, and he wanted to keep on moving.
His viewpoint on conquered peoples began to change somewhat when, in 1211, after subduing several other peoples along the Chinese border, he and his armies went after China itself. The Chinese had long regarded the Mongols as just one of many "barbarian" groups at the fringes of their empire, and had believed that the Mongols' rightful place was as servants to China. Now that was about to change. By 1215, Genghis's hordes, as the Mongol troops were called, had reached Peking, now more commonly known as Beijing (bay-ZHEENG; capital of modern China), which they virtually destroyed. Soon afterward, a former official of the Chinese emperor pointed out to Genghis that if he allowed some people to continue living in the lands he conquered, they could pay him valuable tax money to finance further warfare. Genghis accepted this sound advice, and changed his tactics in the future.
