Yi Bang-won, fifth son of King Taejo, Yi Seong-gye — who had toppled Goryeo and founded Joseon — cut down his brothers and the dynasty’s founding ministers in two “Princes’ Revolts,” and in 1400 he became Taejong, the third king of Joseon. Taejong spared no one who reached for royal power, whether a meritorious minister or his own wife’s family. All four younger brothers of his wife, Queen Wongyeong, died at his hands. This same Taejong had four sons by his queen — Yangnyeong, Hyoryeong, Chungnyeong and Seongnyeong. The throne belonged to the eldest, Grand Prince Yangnyeong.

Though he was ill, the prince would not put down his books. When his father heard of it, he sent eunuchs to take every book out of the room.

EunuchHis Majesty’s orders,
Your Highness.
The prince…Just one —
leave me just one.

The eunuchs left not a single book behind.

An empty room. But wedged between the folding screen and the wall was one book they had failed to take.

歐蘇手簡
The prince…There’s one
still left.

The book was called Guso sugan.

It was a collection of short letters that Ouyang Xiu and Su Shi, masters of prose in Song-dynasty China, had written to their friends.

The prince read it, and read it again.

While the snow fell, the flowers bloomed, the monsoon rains ended and the leaves came down —

One thousand one hundred times.

Until the corners of its pages were worn round.

That prince’s name was Yi Do.

He was born in the fourth month of 1397 in Junsu-bang, Hanyang, the third son of Yi Bang-won. His father was not yet king.

A third son could not become king. The throne was meant for his eldest brother, Grand Prince Yangnyeong.

All that was allowed a third son
was to read his books in quiet.

In the spring of 1408, twelve-year-old Prince Chungnyeong married Lady Sim, two years his senior. She was the daughter of Sim On, who served as the king’s secretary.

Prince ChungnyeongGroom, age 12Lady SimBride, age 14
Prince Chungnyeong…Do you
like books?
Lady Sim…I know my letters,
a little.

On bitter winter nights and sweltering summer nights alike, Chungnyeong read until daybreak.

Lady SimThe rooster has crowed.
Prince Chungnyeong…Just one
more page.

Without a word, his wife turned up the lamp’s wick for him.

His eldest brother, Grand Prince Yangnyeong, preferred hunting and merrymaking to books. The more often their father scolded him, the further the brothers drifted apart.

Again and again, the younger brother urged the elder to mend his conduct. The elder had little patience for such a brother.

In 1418, everything changed.

Crown Prince Yangnyeong misbehaved again and again, and even sent a resentful letter to the father who scolded him.

On the third day of the sixth month,
Taejong deposed his eldest son as crown prince.

Most of the officials wanted Yangnyeong’s young son named instead. But Taejong decided to choose “the worthy one.”

King TaejongThird king of Joseon · age 52
King TaejongBy nature, Chungnyeong is bright,
and he loves learning dearly.
Even on bitterly cold or hot days he reads through the night,
so, fearing he would fall ill, I told him not to read at night —
yet he took all my great volumes and read them.
He grasps the essentials of governing,
and when I ask him about great matters, he offers ideas I had not thought of.

On the eighth day of the eighth month of 1418, Taejong summoned the crown prince and held out to him the king’s seal, the “Great Seal.”

King TaejongMy child, I am giving you the Great Seal now.
Take it.
For eighteen years I have ridden on a tiger’s back.
Now it is enough.

The crown prince stayed prostrate and would not rise. Taejong took him by the sleeve, pulled him up and handed him the Great Seal.

殿政勤

10th day of the 8th month, 1418.

Just two months after becoming crown prince, Chungnyeong ascended the throne in Geunjeongjeon Hall at Gyeongbokgung Palace.

The fourth king of Joseon. He was twenty-two.

His wife, Lady Sim, became queen. She was twenty-four.

But Taejong, now the Retired King, would not let go of one thing: his command of the military.

The new king’s time had not yet come.

What the Retired King Taejong guarded against above all was power growing at the king’s side — the queen’s family, the royal in-laws.

He was the man who had killed all four of his own wife’s younger brothers.

Now those eyes
turned to the new queen’s father.

9th month, 1418.

The queen’s father, Sim On, was made Chief State Councillor and set out for Ming China as an envoy.

So many came out to see off the new king’s father-in-law that the capital was all but empty.

While he was away, officials who had reported military matters to the king ahead of the Retired King were arrested. Under torture, Sim On’s name came from their lips.

In the twelfth month, on his way back from Ming, Sim On was arrested before he even reached the capital.

In the end, he received the Retired King’s order to take his own life.

His daughter had been queen for just four months.

The queen’s mother and her family were reduced to lowborn status.

Before his father, the king could do nothing. The army, the trials — all of it was in the Retired King’s hands.

All the king could do was send a coffin, paper and lime for his father-in-law’s funeral, and dispatch a eunuch to see to the rites.

The twenty-two-year-old king
could not protect his wife’s father.

At court, voices rose calling for the queen to be deposed: how could a criminal’s daughter be left in the place of the nation’s mother?

King TaejongEven a commoner’s daughter, once married,
is not caught up in her own family’s crimes.

The Retired King who had killed the queen’s father protected her place as queen.

That night, a light burned late in the queen’s room.

歐蘇手簡

Deep in the night, the king stood at the queen’s door.

Sejong…I am the king, yet I could not protect even one man — your father.

Instead of answering, the queen brought out an old book.

It was the Guso sugan.

Queen SoheonThe day they took all your books from you — who left this one behind the screen… you still don’t know, do you?

Sejong…It was you, my queen?

Queen SoheonFrom that day on, I have been on your side, Your Majesty. Today, and always.

Until the lamp burned out, the king did not leave her side.

No record tells what the two of them said to each other that night.

The records tell only this.

For twenty-eight years after that,
the queen stayed by the king’s side.

In 1422, the Retired King Taejong died. Then, in the fifth month of 1426, the king freed the queen’s mother, Lady An, from the bonds of lowborn status.

SejongMother and child have not seen
each other in many years —
how their hearts must ache.

Then, choosing an auspicious day early in the sixth month, he let the queen visit her mother’s house. It was the first time she had seen her mother since the winter she lost her father.

The Guso sugan was a book of letters.

The prince who had read other people’s letters one thousand one hundred times,

in the winter of the twenty-fifth year of his reign —
makes the letters with which anyone
can write a letter in their own hand.

    The Guso sugan Behind the Folding Screen

    The entry for the 23rd day of the 12th month of 1423 in the Veritable Records of King Sejong contains this story, set down by a court historian: when Chungnyeong would not put his books aside even while suffering from a mild illness, Taejong had a young eunuch take them all away, but a single volume, the Guso sugan, remained at his side, and he read it through. The story that the book had been left tucked in a folding screen and that he read it one thousand one hundred times is handed down through Seo Geo-jeong’s Pirwon japgi to the Yeollyeosil gisul. The Guso sugan is a collection of short letters (chidu) written by Ouyang Xiu and Su Shi of the Song dynasty. A document sent to Ming after Sejong’s death records that he “always read the classics more than a hundred times.”

    Why Taejong Chose His Third Son

    On the 3rd day of the 6th month of 1418, Taejong deposed Crown Prince Yangnyeong and named Grand Prince Chungnyeong crown prince in his place. Most officials wanted Yangnyeong’s son installed, but Chief State Councillor Yu Jeong-hyeon and others argued that “the worthy must be chosen” (taekhyeon), and Taejong took their advice. As his reasons, Taejong cited Chungnyeong’s intelligence and love of learning and his reading through the night in cold and heat alike; his grasp of the essentials of governing; his bearing when receiving Chinese envoys; his drinking in moderation and knowing when to stop; and the fact that he had a “sturdy son” (the future King Munjong). Queen Wongyeong is said to have objected, warning that deposing the elder brother to raise the younger would sow the seeds of disaster.

    The Retired King Taejong and the Case of Sim On

    Even after handing over the throne in the 8th month of 1418, Taejong kept hold of military authority until his death in 1422. That year, a case was brought against officials of the Ministry of War for failing to report military matters to the Retired King first (the Gang Sang-in case); in the 11th month, during the interrogations, the queen’s father, Chief State Councillor Sim On, was named as its ringleader, and Sim On’s younger brother Sim Jeong and others were executed. Sim On, who had gone to Ming as an envoy of thanks, was arrested on his way home and in the 12th month of that year received the order to take his own life (sasa). Many see it as Taejong guarding against the growing power of the king’s father-in-law. Sim On’s name and offices were restored under King Munjong, after Sejong’s death.

  4. Queen Soheon of the Sim Clan

    Queen Soheon (1395–1446), a daughter of Sim On of the Cheongsong Sim clan, married Prince Chungnyeong in 1408. She became queen when her husband took the throne in 1418, but that winter she lost her father, and her mother and family were reduced to lowborn status. The Uigeumbu and some high officials called for her to be deposed, but Taejong refused, saying that “even a commoner’s daughter, once married, is not caught up in her own family’s crimes.” In the 5th month of 1426, Sejong freed his mother-in-law, Lady An, from lowborn status, saying, “Mother and child have not seen each other in many years — how their hearts must ache,” and early in the 6th month he let the queen visit her family home. Queen Soheon bore eight sons and two daughters; her eldest son was King Munjong, her second Grand Prince Suyang (King Sejo) and her third Grand Prince Anpyeong.

  5. What We Imagined

    The words exchanged between the prince and the eunuch on the day the books were taken, between the groom and the bride on their wedding day, and beneath the lamp are invented. Above all, that the one who left the book behind the screen was his young wife, and the words the king and queen exchanged on the night Sim On died, are not in the records. The Yeollyeosil gisul says only that the book “had remained” in the folding screen.
