At length, a joint attempt on the part of seven States, aided by two Mongol chieftains, was made to crush him; but, although numerical superiority was overpoweringly against him, he managed to turn the enemy's attack into a rout, killed four thousand men, and captured three thousand horses, besides other booty.

Following up this victory by further annexations, he now began to present a bold front to the Chinese, declaring himself independent, and refusing any longer to pay tribute.
In 1604, he built himself a new capital, Hingking, which he placed not very far east of the modern Mukden, and there he received envoys from the Mongolian chieftains, sent to congratulate him on his triumph.
At this period the Manchus, whose spoken words were polysyllabic, and not monosyllabic like Chinese, had no written language beyond certain rude attempts at alphabetic writing, formed from Chinese characters, and found to be of little practical value.

The necessity for something more convenient soon appealed to the prescient and active mind of Nurhachu; accordingly, in 1599, he gave orders to two learned scholars to prepare a suitable script for his rapidly increasing subjects.

This they accomplished by basing the new script upon Mongol, which had been invented in 1269, by Baschpa, or 'Phagspa, a Tibetan lama, acting under the direction of Kublai Khan.

Baschpa had based his script upon the written language of the Ouigours, who were descendants of the Hsiung-nu, or Huns.
