This Mongol, usually so calm, so impassible, with his cool look beneath his motionless eyelid, had become a prey to a sort of furious anxiety which he appeared incapable of controlling.

Now Mongols are constituent elements in the populations of China, Russian, and Turkish Asia.

Not until the Mongols became a power did the Hsia recover some of their importance; but they were among the first victims of the Mongols: in 1209 they had to submit to them, and in 1227, the year of the death of Genghiz Khan, they were annihilated.

Yet another point is characteristic: the Mongols were the first alien people to rule the whole of China; the Manchus, who appeared in the seventeenth century, were the second and last.
