With his followers, Kung-wo attacked the city of Kaichow (in the modern Kang-wen province), and was so far successful as to enter it and proclaim himself king. His personal success was of short duration. His lieutenant, Wang-ken, that is Wang the founder, was a descendant of the old kingly house of Korai. During all the time of Chinese occupancy, or Shinra supremacy, his family had kept alive their spirit, traditions, and claims. Thinking he could rule better than a priest, Wang put the ex-monk to death and proclaimed himself the true sovereign of Korai. All this went on without the interference of China, which at this time was torn by internal disorder and the ravages of the same Kitan tribes that had destroyed Puhai. Wang made Ping-an and Kaichow the capitals of his kingdom, and resolved to take full advantage of his opportunity to conquer the entire peninsula and unite all its parts under his sceptre. Circumstances made this an easy task. With China passive, Shinra weak, through long absorption in luxury and the arts of peace, and with most part of the population of the peninsula of Koraian blood and descent, the work was easy. The whole country, from the Ever-White Mountains to Quelpart Island, was overrun and welded into unity. The name of Shinra was blotted out after a line of fifty-six kings and a life of nine hundred and ninety-three years. For the first time the peninsula became a political unit, and the name Korai, springing to life again like the Arabian phœnix out of its ashes, became the symbol alike of united Corea and of the race which peopled it. Even yet the name Korai (Gauli or Gori in the vernacular) is generally used by the people. The probabilities are that the people of the old Fuyu race, descendants of the tribes of Kokorai, as the more vigorous stock, had already so far supplanted the old aboriginal people inhabiting Southern Corea as to make conquest by Wang, who was one of their own blood, easy. This is shown in a series of maps representing the three kingdoms of Corea from 201 to 655 A.D., by the Japanese scholar Otsuki Tōyō. At the former date the Kokorai people beyond that part of their domain conquered by China have occupied the land as far south as the Han River, or to the 37th parallel. Later, Shinra, in 593, and again in 655, backed by Chinese armies, had regained her territory a degree or two northward, and in the eighth and ninth centuries, acting as the ally of China, ruled all the country to the Tumen River. Yet, though Shinra held the land, the inhabitants were the same, namely, the stock of Korai, ready to rise against their rulers and to annihilate Shinra in a name and monarchy that had in it nationality and the prestige of their ancient freedom and greatness.
