In the northeast of China, beyond the Great Wall and bordering on Corea, lies the province of Liautung. Northward from this to the Amur River extends the eastern section of the steppes, known on modern maps as Manchuria. From these broad wilds the Kins had advanced to their conquest of Northern China. To them they fled for safety from the Mongol arms, and here lost their proud name of Kin and resumed their older and humbler one of Niuche. For some five centuries they remained here unnoticed and undisturbed, broken up into numerous small clans, none of much strength and importance. Of these clans, which were frequently in a state of hostility to one another, there is only one of interest, that of the Manchus.

The original seat of this small Tartar clan lay not far north of the Chinese border, being on the Soodsu River, about thirty miles east of the Chinese city of Moukden. Between the Soodsu and Jiaho streams, and south of the Long White Mountains, lies the valley of Hootooala, a location of rugged and picturesque scenery. This valley, protected on three sides by water and on the fourth by a lofty range of mountains, the whole not more than twelve miles long, formed the cradle of the Manchu race, the narrow realm from which they were to emerge to victory and empire. In a certain respect it resembled the native home of the Mongols, but was far smaller and much nearer the Chinese frontier.

In this small and secluded valley appeared, about the middle of the fourteenth century, when the emperor Hongwou was fighting with the Mongols, a man named Aisin Gioro. Tradition attributes to him a miraculous birth, while calumny asserts that he was a runaway Mongol; but at any rate he became lord of Hootooala and ancestor of its race of conquerors. Five generations from him came a chief named Huen, who ruled over the same small state, and whose grandson, Noorhachu by name, born in 1559, was the man upon whom the wonderful fortunes of the Manchus were to depend. Like many other great conquerors, his appearance predicted his career. "He had the dragon face and the phœnix eye; his chest was enormous, his ears were large, and his voice had the tone of the largest bell."

He began life like many of the heroes of folk-lore, his step-mother, when he was nineteen years of age, giving him a small sum of money and turning him out into the world to seek his fortune. She repented afterwards, and bade him come home again or accept further aid, but the proud youth refused to receive from her any assistance, and determined to make his own way in the world.

Noorhachu first came into notice in 1583. In that year Haida, chief of a small district south of Hootooala, made an attack, assisted by the Chinese, on some neighboring clans. One of these was governed by a relative of the old Manchu chief Huen, who, with his son and a small force, hurried to his aid and helped him to defend his town. Haida and his allies, finding the place too strong for them, enticed a part of the garrison outside the walls, and then fell upon and treacherously massacred them. Among the slain were Huen and his son.

This brutal murder left Noorhachu chief of his clan, and at the same time filled him with a fierce desire for revenge, both upon Haida and upon the Chinese. He was forced to bide his time, Haida gaining such influence with his allies that he was appointed by them chief of all the Niuche districts. This act only deepened the hatred of Noorhachu, who found himself made one of the vassals of the murderer, while many of his own people left him and attached themselves to the fortunes of Haida.

Fortunately for the youthful chief, the Chinese did not strongly support their nominee, and Noorhachu pursued his rival so persistently that the assassin did not feel safe even within his stockaded camp, but several times retreated for safety into Liautung. The Chinese at length, tired of supporting a man without the courage to defend himself, seized him and handed him over to Noorhachu, who immediately put him to death.

The energy and success of Noorhachu in this scheme of vengeance gave him a high reputation among the Niuche. He was still but twenty-seven years of age, but had probably laid out his life-work, that of making himself chief of a Niuche confederacy, and employing his subjects in an invasion of Chinese soil. It is said that he had sworn to revenge his father's death by the slaughter of two hundred thousand Chinese.

He began by building himself a stronghold. Selecting a site in the plain where water was abundant, he built a town and surrounded it with a triple wall. This done, he began the work of uniting the southern clans under his sway, a task which proved easy, they being much impressed by his victory over Haida. This peaceful progress was succeeded by a warlike movement. In 1591 he suddenly invaded the district of Yalookiang, which, taken by surprise, was forced to submit to his arms.

This act of spoliation roused general apprehension among the chiefs. Here was a man who was not satisfied with petty feuds, but evidently had higher objects in view. Roused by apprehension of danger, seven of the neighboring chiefs gathered their forces, and with an army of thirty thousand Niuche and Mongols invaded the territory of the daring young leader. The odds against him seemed irresistible. He had but four thousand men to oppose to this large force. But his men had been well chosen and well trained, and they so vigorously resisted the onset of the enemy that the principal Niuche chief was killed and the Mongol leader forced to flee. At this juncture Noorhachu charged his foes with such vigor that they were broken and put to flight, four thousand of them being slain in the pursuit. A number of chiefs were taken prisoners, while the spoils included several thousand horses and plaited suits of armor, material of great value to the ambitious young victor.
