The First Boy Emperor of Han

The most solid fact about the first boy emperor of Han is that we do not know his name. He is called Liu Gong in almost every modern reference work, and the name appears in popular histories and television dramas without qualification. No Han source contains it. The Records of the Grand Historian and the Book of Han, the two histories written closest to his lifetime, both leave the emperor's personal name blank. In their pages he is "the crown prince," "the young emperor," or simply "a son of the rear palace." The name he is known by today was invented by accident, in Japan, in 1909.
That accident is worth stating plainly, because it is the best evidence we have of what kind of figure he was. His life was arranged before he was old enough to speak and ended before he was old enough to be a threat, and the only thing he ever did on his own initiative was to say one sentence, which killed him. The sentence is recorded, in his own words, in the Records of the Grand Historian. His name is not.

1. A Name That No Han Source Records

The oldest surviving statement of the problem comes from Liang Yusheng, a Qing-dynasty scholar who worked through the discrepancies in the Records in a book called Doubts About the Records of the Grand Historian. Writing in the eighteenth century, he paused over the boy and concluded: "Here he is called the young emperor; neither the Records nor the Book of Han gives his name. He was a son of Xiaohui's rear palace." Liang Yusheng was correcting an earlier gloss, from the Tang commentary of Zhang Shoujie, which had offered an explanation of the boy's parentage that Liang dismissed as fabrication. The name itself he simply noted as absent.
It stayed absent for another century and a half. Then, in 1909, a chronological table of Chinese history was published in Japan, and in the entry for the reign of Empress Lü its compiler wrote Shaodi Gong — "the young emperor Gong." The Japanese scholar Yamada Takahito, examining the textual history in a 2017 article, concluded that the character gong was almost certainly a miswriting of the character mou, "so-and-so" — that is, a placeholder meaning "the young emperor, someone," which was mistaken for a name. Once printed in a reference table, it travelled. It was picked up by translators, then by general histories, then by the Cambridge History of China, and by the twentieth century it had hardened into fact in Chinese, English and Japanese alike. Qian Mu's Outline of National History, a standard twentieth-century survey, lists him in its imperial genealogy as Shaodi Gong.
The episode is a small parable about how historical figures acquire identities. It also tells us something specific: the sources were rich enough to preserve the words of a child, in direct speech, and not rich enough to preserve his name. That combination — verbatim quotation on one side, total anonymity on the other — is not an accident of survival. It is what a record looks like when the people keeping it have decided that the subject matters only as a piece of a political problem.

2. The Borrowed Son

He was born to one of Emperor Hui's lesser consorts — the sources call her a meiren, a woman of the rear palace, and give no name. He was, in other words, a son of no particular consequence, until the empress dowager needed him.
The problem in 192 BC was that Emperor Hui's marriage was barren. His wife, Queen Zhang Yan, was the daughter of his own sister, married to him at about eleven years old at the arrangement of the empress dowager, and no child was going to come of it. Lü Zhi's solution was procedural. As the Records puts it in its chapter on the relatives of the imperial consorts, "Because of her wish for a close marriage, she wanted [the queen] to bear a son by every means, and in the end there was none; so she falsely took a son of the rear palace as her son." The Basic Annals of Empress Lü spells out the mechanics: the queen was made to feign pregnancy, and when the time came a child was produced, credited to her, and made crown prince. The boy's mother had already been killed — the phrase is blunt, and it is the only mention she receives: "she killed his mother."
The scheme's purpose was not to give Liu Ying an heir; he was not consulted. It was to make the succession something the empress dowager controlled, by removing an inconvenient mother and substituting a child with no kin of his own. He was made crown prince at about four or five. When Emperor Hui died in 188 BC, the boy took the throne, and Empress Lü took the government, as regent for a grandson she had manufactured.

3. Four Years Without a Calendar

The clearest measure of what his reign amounted to is that it was never dated in his name. On the death of an emperor, his successor was expected to declare a new reign era from the following year; that declaration was how the state told time, and it was how an emperor existed in administrative reality. The boy emperor never made one. Sima Qian states the reason in six characters when he describes the same arrangement for the next boy: not declaring a first year, because the empress dowager was running the affairs of the empire. The years from 188 to 184 BC were counted as the reign of the empress dowager, and the Book of Han duly files them under the annals of Empress Lü.
So there was an emperor, and there was no year of his. In the surviving record of those four years there is no decree issued by him, no deliberation he presided over, no appointment he made. What the histories record instead is a steady transfer of power to the Lü clan: in 187 BC the empress dowager established her brother's son Lü Tai as King of Lü, carving the commandery of Jinan out of the kingdom of Qi to give him a territory; other kinsmen were raised to marquisates and placed in the capital's offices and armies. Marriage was part of the same programme. One of the Lü daughters was married to the boy emperor, a match the Records explains in one line — to bind the roots of the arrangement "firmly and deeply." She was, effectively, a second set of eyes on a child who had not yet learned he had no freedom.
None of this was hidden. Officialdom understood perfectly well who gave orders. What the empress dowager needed the boy for was the legitimacy that came from having a Liu on the throne while a Lü ran the state; a regent rules for an emperor, and an emperor is required. That was his function, and for four years he performed it by existing.

4. The Sentence He Should Not Have Said

Then, in 184 BC, he found out.
The Basic Annals says he had grown — the word is zhuang, which can mean anything from older to physically grown — and that someone told him the truth: that the woman he called mother was not his mother, and that his real mother had been killed. His response is one of the very few passages of direct speech the histories give to any of these children, and it is worth quoting as it stands. "How could the empress have killed my mother and then call me her son? I am not yet grown. When I am grown, I will make trouble for her."
There is no evidence that he had a plan, or supporters, or a single soldier. A boy of perhaps eight or ten, with no maternal kin — his mother's family had been erased along with the mother — could threaten nothing. What he did have, and what the empress dowager understood immediately, was a grievance that was factually correct and publicly unanswerable. The sentence confirms that he knew the crown he wore had been bought with a murder, and a ruler who knows that can never be made to forget it.
The response was administrative, and it followed a pattern that would be repeated. The empress dowager had him confined in the Yongxiang, a compound within the palace, announced that he was gravely ill and ordered that no one be allowed to see him. Sima Qian notes: "the empress dowager had him kept secretly and spoke of the emperor being very ill, and none of the attendants were allowed to see him." Then she went to her officials with a proposal about her own grandson, dressed as a medical opinion: "The emperor's illness has now lasted a long time and shows no sign of ending; he is confused and disordered in mind, and cannot inherit and carry on the sacrifices of the ancestral temple or be entrusted with the empire. Let us consider replacing him." The officials duly considered it. He was deposed, and quietly killed. The Records gives the whole outcome in one short sentence — deposed, then quietly put to death — and moves on to the appointment of the next boy.
The reasoning that killed him was not about the threat he posed, which was nil, but about the threat he represented: any emperor who knew his own history was a permanent objection to the settlement that had produced him. That was true of him in 184 BC, and it would be true of his successor four years later.

5. Erased from the Line of Emperors

He left nothing behind him that anyone would want to claim. He has no temple name, no posthumous title, no mausoleum in the Western Han imperial sequence — the emperors from Gaozu to Pingdi have tombs, and he does not. In the Records he has no annals; in the Book of Han his four years sit inside the annals of Empress Lü. The designation by which he is now universally known, "the first young emperor," is a later convenience invented to tell him apart from the boy who followed him; it is not a title anyone gave him in 184 BC.
What happened to his name is the last turn of the story. He was wiped out of the succession, out of the calendar, and out of the genealogy, and he stayed anonymous for two thousand years — until a Japanese compiler needed a word for him in a timeline and wrote down a slip of the pen. The false name spread further and faster than anything true about him ever had, and by the twenty-first century it was in encyclopaedias, textbooks and costume dramas, along with an invented personality, invented motives and invented scenes. He is remembered by a mistake and not a biography.
And yet the one thing he is best known for saying, he did say. The histories may have lost his name, but they kept the sentence in which he told the empress dowager, to her face, that he knew what she had done and would not forget it. It is a very thin record for a reign of four years. It is also, for a boy with no name, no kin and no power, the only thing he had.
