50 BCA golden foundling becomes heirsuccession crisis
A king with no son of his own found, beneath a weeping horse and an overturned boulder, a golden child shaped like a toad - and raised him as Geumwa, the heir his own prayers had failed to produce by ordinary means. The kingdom relocated eastward not long afterward, to a new seat near the White Head Mountain.

A dispute over the meaning of a two-bodied crow, each side reading the same omen as proof of its own coming victory, ended in an actual war rather than a symbolic one: Goguryeo's army broke the Buyeo forces before their own capital and accepted the kingdom's surrender once its king had died trying to spring a night ambush that instead mired his own troops in a marsh.

A toad-shaped answer to prayer
Drafted from Hulbert, The History of Korea, Volume I (1905)formation
King Hă-bu-ru of Buyeo had one sorrow no victory or treaty could
resolve: no son to inherit his throne. Riding alone through the forest
one day, tradition says, he dismounted by a rushing stream and prayed
to the Great Spirit for an heir. When he turned to remount, he found
his own horse standing before a boulder with tears running down its
face. Overturning the stone, he discovered beneath it a child the
color of gold, shaped like a toad.
A kingdom that moved with its own heir
Hă-bu-ru raised the foundling as his son, naming him Geumwa - "Golden
Toad" - and not long afterward the kingdom itself relocated eastward,
settling near the White Head Mountain under the new name East Buyeo.
Whether the move and the succession were connected, or simply
remembered together because they happened close in time, the
tradition does not say; what it makes clear is that Geumwa grew up
expecting to rule a kingdom that had already reshaped itself around
his own arrival.
A bride already marked by a god
When Geumwa reached manhood he found, weeping by a shoreline, a young
woman named Yu-hwa who claimed to be the daughter of the Sea King,
driven from her own family's home after being seduced by a wandering
spirit. Geumwa took her into his household as a wife, but confined her
to a chamber lit by only a single narrow aperture - a precaution that
did nothing to prevent what happened next. A ray of sunlight found its
way to her regardless, and by it, tradition says, she conceived.
An heir who arrived already unwelcome
What Yu-hwa eventually produced was not a child but an egg the size of
five measures of grain - an object so unnatural that Geumwa, in anger,
threw it to be destroyed by his own animals. Pigs and dogs would not
touch it; cattle and horses warmed it with their breath instead, and a
stork descended to shelter it beneath her own wings. Geumwa relented
and allowed Yu-hwa to keep it, and in time it broke open to reveal a
boy whose skill with a bow, evident by the age of seven, would earn
him a name of his own - and, before long, more enemies at court than
any child should have to face.
The archer the court tried to kill
Drafted from Hulbert, The History of Korea, Volume I (1905)contraction
The egg-born boy took the name Chu-mong - "Skillful Archer" - for a
talent with the bow that became apparent almost as soon as he could
hold one. Geumwa protected him and made him keeper of the royal
stables, but the boy was never popular with the rest of the court, and
his own seven half-brothers watched his growing skill with open
resentment rather than pride in a sibling.
A stable-keeper who outwitted his own rivals
Chu-mong turned his humble post to quiet advantage: he starved the
kingdom's best horses just enough to make them lean and unremarkable
while fattening the poorer ones for show, keeping the finest mounts
effectively invisible until a hunt began, when he alone could outrun
every other rider in the field. His brothers, already jealous of his
archery, now had a fresh grievance, and between them they resolved
that the foundling's foundling had to die.
A mother's warning and a river that answered a prayer
Warned in the night by his own mother, Chu-mong fled south before dawn
with three loyal companions, only to find his path blocked by a river
with no boat, bridge or ford in sight and his brothers' pursuing
cavalry already audible behind him. Striking the water with his bow
and calling on the river's own spirit for aid, he watched - so the
tradition insists - as a shoal of fish and tortoises rose from the
depths and pressed their backs together into a living bridge.
A kingdom his own flight would come back to haunt
Crossing safely while his brothers were left stranded on the far bank,
Chu-mong continued south, gathered new followers along the way, and
founded a kingdom of his own at Chŭl-bon - naming it Goguryeo, after
his own family name and a mountain from his native Buyeo. The court
he had fled had lost, in that single night, the one member of its own
royal household who would go on to found the kingdom that would
eventually return and conquer it outright.
A crow with two bodies
Drafted from Hulbert, The History of Korea, Volume I (1905)end
Dae So, king of Buyeo a generation after Chu-mong's flight, came into
possession of an unusual omen: a red crow with two bodies but a single
head. His own soothsayers read it as a sign that two countries would
be joined under one ruler, and Dae So, pleased with the interpretation,
concluded it meant Buyeo would conquer Goguryeo - the kingdom his own
family's runaway prince had founded to the south. He sent the crow to
Goguryeo's king as a formal declaration of the coming war.
An omen read two ways
Goguryeo's king answered with an interpretation of his own: red, he
noted, was the color of the south, and the omen therefore pointed to
Goguryeo's victory over Buyeo rather than the reverse. Rather than wait
to be proven right or wrong by events, he took the initiative himself,
sending a powerful army north before Dae So could act on his own
confident reading of the crow.
A night attack that mired its own army
Dae So attempted to catch the invading force by surprise, launching a
night attack as Goguryeo's troops camped before an extensive marsh
near his own capital. The attempt went badly: his own soldiers became
mired in the swamp they had chosen to cross, and a giant warrior
fighting on Goguryeo's side waded into the mud and returned carrying
Dae So's own severed head. With their king dead, the Buyeo army
surrendered outright.
A kingdom that ended without entirely disappearing
Not every survivor accepted the outcome. Dae So's own brother escaped
with a hundred followers and settled near the Yalu River, founding a
smaller holding Goguryeo chose to overlook rather than pursue further.
The main Buyeo kingdom - the one Chu-mong had fled a generation
earlier, and the one whose own throne had once been decided by a
golden foundling and a sunlit egg - ended in a single defeat before the
capital its own founding dynasty had built.
Goguryeo's own founding dynasty, itself descended from a prince who had fled Buyeo a generation earlier, returned to conquer the kingdom he had left - accepting the surrender of Buyeo's army after its king died in the field, though the dead king's brother escaped with a hundred followers to found a smaller holding Goguryeo chose not to pursue.
