Nine chiefs' confederacy of one leading state and five dependencies, founded by a legend of six boys hatched from golden eggs, whose king kept his own throne under Silla even after surrendering his sovereignty to her without a fight.

41The nine chiefs' confederacytreaty
Nine district chiefs pooled their own lands under one crown, said by their own shared account to have been found inside a golden egg on a mountainside - and five other boys hatched from the same clutch became chiefs of five further states that carried the confederacy's own name outward from its leading one.

527Kim Ku-hyŭng's submissiontreaty
Rather than risk becoming contested ground between the peninsula's two rising powers, Ka-rak's own king surrendered his sovereignty to Silla outright and was kept on as governor of his former kingdom under Silla's own appointment - a change the source's scanty records give no sign of being anything but peaceful.

Six eggs in a golden box
Drafted from Hulbert, The History of Korea, Volume I (1905)formation
In 41 CE the chiefs of nine districts bearing the shared suffix -gan —
A-do-gan, Yŏ-do-gan, P'i-do-gan, O-do-gan, Yu-su-gan, Yu-ch'ŭn-gan,
Sin-ch'ŭn-gan, Sin-gwi-gan and O-ch'ŭn-gan — agreed to merge their own
territories into a single confederacy they called the Kingdom of Ka-rak,
setting its capital at the site of present-day Kim-hă. Tradition credits
the moment of founding to a banquet on Sung-bong, where the assembled
chiefs saw a strange cloud settle on the mountainside and heard a voice
call down from the sky. Climbing to investigate, they found a golden box
containing six golden eggs, which opened to reveal six boys. One, Kim
Su-ro, became king of Ka-rak itself; the other five were made chiefs of
five further states — So-ga-ya, Ko-ryŭng-ga-ya, Song-san-ga-ya, Tă-ga-ya
and A-ra-ga-ya — that carried the shared name Ka-ya outward from the
confederacy's own leading member.
A queen who arrived by sea
Kim Su-ro's own queen, tradition says, came to him by boat rather than
by any local match: a woman named Ho, styled Whang-ok or "Yellow Jade,"
sailed from a distant southern kingdom called A-yu-t'a, also known as
Ch'ŭn-ch'uk. She is said to have lived a hundred and fifty-seven years,
with the king surviving her by only one. Beyond this legend and a bare
list of kings, the source states plainly that little else survives of
Ka-rak's own internal history — no wars of conquest, no succession
crises, nothing but a founding and, five centuries on, an end.
A confederacy not much smaller than its rival
At its own greatest extent Ka-rak reached east to the Wang-san River,
northeast to Ka-ya San, and south and west to the coast and Chi-ri San —
a footprint the source calls "little inferior to Silla in size." For
nearly five centuries the confederacy held this ground as an
independent neighbor to Silla, Baekje and Goguryeo alike, never
absorbed by force and never expanding much beyond the territory its
nine founding chiefs first agreed to share.
A throne kept under new management
Drafted from Hulbert, The History of Korea, Volume I (1905)end
By the early sixth century Ka-rak's king, Kim Ku-hyŭng, faced a
calculation his own predecessors had never had to make so starkly:
Silla's power was growing steadily on his own doorstep, and a small
confederacy sandwiched between larger neighbors risked becoming
disputed ground rather than a state in its own right. In 527 he chose
to settle the question himself, surrendering Ka-rak's sovereignty to
Silla outright rather than wait to see which of the peninsula's rising
powers would eventually take it by force.
A submission, not a conquest
The source's own scanty records give no indication that this was
anything but a peaceful transfer. Silla did not garrison Ka-rak's own
capital or replace its ruling house; instead, Kim Ku-hyŭng was retained
at the head of his former kingdom, now governing it under appointment
from the king of Silla rather than in his own right. A confederacy that
had stood as an independent neighbor to Silla for close to five hundred
years ended not on a battlefield but at a negotiating table, in an act
the source records without a single detail suggesting resistance on
either side.
An arithmetic the records themselves cannot settle
Even the length of Ka-rak's own existence draws a rare moment of
editorial correction from the source: the records state the kingdom
lasted four hundred and eighty-two years, but the founding date of 41
and the end date of 527 that those same records supply add up to four
hundred and eighty-six. The source lays the discrepancy at the door of
whoever first tallied the figure rather than choosing between the two -
a small case of a source disagreeing with its own arithmetic, left
standing rather than smoothed over.
A musician who saw it coming
Drafted from Hulbert, The History of Korea, Volume I (1905)afterlife
Ka-rak's own submission in 527 did not end the confederacy it had
led. The five dependent states founded alongside it in the golden-egg
legend — So-ga-ya, Ko-ryŭng-ga-ya, Song-san-ga-ya, Tă-ga-ya and
A-ra-ga-ya — carried on for decades under their own chiefs, outlasting
the state that had given the whole confederacy its name.
A master musician reads the omens
In 552 the king of Silla sent three students, Pŭp-ji, Kye-go and
Man-dok, to the Ka-ya country to learn music from a celebrated master
named U Reuk. But U Reuk had already read the direction events were
taking: judging his own homeland doomed, he took his twelve-stringed
instrument and his disciple Ni Mun and moved to the Silla court himself
rather than wait for Silla to come to him. The three students studied
under him there — one singing, one the instrument, one dance — and when
they tried to edit his songs for what they considered excessive
license, the old master refused outright and the plan was dropped. From
this exchange the instrument itself, the kayageum, took the name of the
homeland it came from and remains, under that name, part of Korean
music today.
An end the source will not date precisely
The remaining Ka-ya states did fall to Silla in the end, in the reign of
Silla's King Chin-heung — "some five hundred years" after the
confederacy's own 41 CE founding, by the source's own reckoning, though
no more exact year or narrated campaign survives to fix the date more
closely. Whatever the precise year, U Reuk's own flight to Silla shows
that Ka-ya's fate was already legible to at least one of its own people
a generation after Ka-rak had given up its sovereignty peacefully.
A grave robbed, centuries later
Ka-ya's own memory outlived its politics. Tradition holds that when
Silla itself fell in 935, several men who had defiled Kim Su-ro's own
grave died in short order by strange means — one crushed by a falling
beam, one shot by an unseen archer, nine others killed by a serpent
eighteen feet long. Centuries after that, the source adds, Japanese
soldiers who opened the same grave during a great invasion found it
still furnished with gold and jade, and beside the king's own outsized
skull lay the remains of two women whose features held their shape only
until the air reached them.
Ka-rak's own king, Kim Ku-hyŭng, surrendered his sovereignty to Silla outright rather than risk his small confederacy becoming disputed ground between larger neighbors, and was kept on to govern his former kingdom under Silla's own appointment.
