peninsula had been separate for centuries. * The people of the peninsula claimed an ancient and distinguished heritage. According to their own myths, the first kingdom in their land was Choson, created by the god Tan’gun in 2333 BC —the era of the oldest Chinese kingdoms.
Before its collapse, the Chinese dynasty of the Han had captured the land across the north of the peninsula and had settled Chinese officials and their families there. In the south, three independent kingdoms formed: Silla, Goguryeo, and Baekje. Meanwhile, on the very southern tip of the peninsula, a fourth set of tribes—the Gaya confederacy—resisted attempts by its neighbors to fold it into the increasingly strong monarchies.
The kingdom of Goguryeo had always been the most aggressive and the most troublesome to the Han, who had hoped to keep the kingdoms south of their colonies from developing too much power: “By temperament,” the Romance of the Three Kingdoms remarked, “the people [of Goguryeo] are violent and take delight in brigandage.” 1 By the time the Han empire fell, its control over its lands in old Choson had shrunk to a single administrative district: Lelang, centered around the old city of Wanggomsong—modern Pyongyang.
7.1: Goguryeo at Its Height
Lelang outlasted its Han parent, surviving until 313. In that year, the ruler of the kingdom of Goguryeo, the ambitious and energetic king Micheon, pushed his way north and captured Lelang, adding it to his own territory and ousting the remaining Chinese forces. This made Goguryeo, under King Micheon, three times the size of any of its neighbors. It was the most powerful, the most dominant of the Three Kingdoms of Korea.
Which made it the biggest target as well. King Micheon died in 331, leaving his son Gogugwon on the throne. King Gogugwon was apparently not a warrior equal to his father; he followed a thirty-year policy of inaction, during which Goguryeo was sacked twice. In 342, armies from the Sixteen Kingdoms took thousands of prisoners and broke down the walls of its capital city, Guknaesong; in 371, the crown prince of Baekje led an invading army all the way up to Wanggomsong.
Shaken out of his withdrawal, King Gogugwon of Goguryeo came out in person to fight his neighbor. He was killed defending the Wanggomsong fortress. Baekje claimed much of Goguryeo’s territory as its own; and Sosurim, son of the defeated king, grandson of the great Micheon, was left with the shrunken shambles of Goguryeo.
Not long after he came to the throne, a Buddhist monk travelling from the west arrived at his court. This monk, Sun-do, brought with him gifts and Buddhist scriptures, along with the assurance that the practice of Buddhism would help to protect Goguryeo from its enemies. King Sosurim welcomed Sun-do and listened to him, and in 372 embraced the faith as his own. The following year, he established the T’aehak: the National Confucian Academy, patterned on Chinese principles. 2
Buddhism and Confucianism, essentially very different, formed a useful hybrid for Goguryeo. Sun-do taught Sosurim and his court that discontent, unhappiness, ambition, and fear were samskrita , conditions of the mind that were nonexistent: the enlightened student recognized that in fact there was no discontent, no unhappiness, no ambition, no fear. The kingdom of Goguryeo was itself samskrita , a conception that had no ultimate reality. Should King Sosurim and his officials truly understand this, they would be able to function in the world while recognizing (in the words of the Zen master Shengyan) that “the world and phenomena have no true existence.” Their decisions would not be shaped and tainted by the desire for gain, the desire for security, the desire for happiness. 3
Confucianism, on the other hand, accepted the reality of the physical world and taught its adherents how to live properly, with virtue and responsibility, within it. The principles of Buddhism gave Goguryeo a new unity, a
