父權、黨爭與宮廷悲劇：朝鮮王朝「壬午禍變」的歷史全貌

公元 1762 年（朝鮮英祖 38 年），朝鮮半島發生了一起震驚後世的宮廷慘劇。朝鮮第 21 代君主英祖李昑，將自己年僅 27 歲的親生兒子、王世子李愃（後追封為思悼世子）廢為庶人，並將其鎖入狹小的米櫃之中。在不提供任何食物與飲水的情況下，李愃在酷暑中掙扎了八天，最終活活餓死。這起史稱「壬午禍變」的事件，不僅是朝鮮王朝歷史上最為殘酷的政治清算之一，更深刻揭示了封建專制王權、嚴苛父權教育以及宮廷黨爭交織出的深層悲劇。

一、 承載極高期望的孤獨繼承人: 英祖李昑是朝鮮歷史上在位時間最長、壽命最長的君主，其在位期間開創了著名的「英祖中興」。然而，這位在政治上極具建樹的帝王，在子嗣問題上卻歷經坎坷。英祖的大兒子李緈早夭，使其長年面臨繼承人斷絕的危機，直到他 42 歲那年，嬪御映嬪李氏才為他誕生了次子李愃。

李愃的誕生讓英祖欣喜若狂，立刻將其冊立為元子，並在三歲時冊封為王世子。自幼展現極高聰慧的李愃，被英祖寄予了極高的期望。然而，這份過度沉重的期許，卻成了李愃幼年生活的噩夢。英祖對世子的教育近乎苛刻，不僅極早讓他接觸《孝經》、《小學》等儒家經典，要求其言行舉止完全符合聖賢標準，甚至在世子僅八歲時便安排其參與宗廟祭祀，九歲迎娶世子嬪（即後來的獻敬王后，惠慶宮洪氏）。在極度高壓且缺乏童年溫情的成長環境下，李愃從小對父親產生了強烈的畏懼心理，為其成年後的精神失常埋下了深遠的伏筆。

二、 黨爭夾縫與代理聽政的性格撕裂: 在李愃 14 歲時，英祖因病命其「代理聽政」，讓世子提前參與朝政。這項安排非但沒有成為世子接班的順利過渡，反而將他推入了朝堂黨爭的風口浪尖。當時朝鮮朝廷主要由老論派與少論派兩大朋黨把持，英祖本身依靠老論派的支持上位，朝政基本由老論派掌控；然而，代理聽政的李愃卻主張執行平衡各方勢力的「盪平政策」，甚至在諸多決策上傾向於少論派。

世子政治立場的轉變，引發了老論派強硬派大臣的極大恐慌與敵意，朝堂上開始出現大量針對世子的告密與誹謗。父子二人不僅在治理理念上產生嚴重分歧，英祖對世子在政務上的嚴厲呵斥與不信任，更讓世子長期處於極度的焦慮與精神高壓之下。隨後，英祖的寵妃文氏誕生了公主，老論派甚至暗中企圖廢黜世子，種種外在威脅使李愃的精神狀態徹底崩潰，逐漸患上嚴重的躁鬱症與狂躁症。

三、 瘋狂行為與難以挽回的局勢: 精神失常後的李愃，行為變得日益失控與暴力。根據《恨中錄》與《朝鮮王朝實錄》記載，李愃在病情發作時，不僅經常虐待並殺害宮中的太監與宮女，甚至曾私自潛出宮外。在極度痛苦中，世子曾三次試圖投井或跳湖自殺，但均被侍從及時救起。

隨著世子嫡母貞聖王后與嫡祖母仁元王后的相繼去世，宮中能夠為世子緩衝與調解的人脈徹底斷絕，李愃的精神病情惡化至無可救藥的地步。世子的瘋狂舉動不僅嚴重威脅到宮廷的安全，更讓英祖對這位繼承人徹底絕望。此時，世子李愃與世子嬪洪氏所生的兒子李祘（後來的朝鮮正祖）展現出了卓越的才華與賢德，深受英祖喜愛。為了確保王室血脈與政權的順利交接，英祖開始認真考量犧牲世子以保全世孫的極端選項。

四、 米櫃中的悲劇與歷史餘波: 公元 1762 年農曆五月，世子的生母映嬪李氏為了保全世孫李祘以及朝鮮宗廟社稷，親自向英祖告發了世子的種種瘋狂罪行，懇求英祖作出決斷。然而，在當時的宗法與法律體系下，若以賜死或處決的方式殺害世子，世子將被列為罪人，這不僅會引發清朝宗主國的追究，更會使世子的妻兒（包括世孫李祘）受到牽連，失去繼承大統的正統性。

為了在不廢除世孫繼承權的前提下除掉世子，英祖最終採取了極其殘忍且折衷的手法。他命人搬來一個儲存米糧的大木櫃，下令將李愃廢為庶人並鎖入米櫃之中，隨後將米櫃放置於昌慶宮文政殿前，嚴禁任何人提供食物與水。經歷八天的絕水絕食，李愃於六月初一在米櫃中氣絕身亡。

世子死後，英祖內心充滿了深切的悲傷與悔恨，親自賜予其諡號「思悼」，意為「思念其悲悼之情」。世孫李祘隨後過繼給早逝的兄長李緈，得以順利維系正統繼承資格，並在英祖駕崩後繼位為正祖。正祖即位後，為了洗刷父親的污名，將思悼世子追尊為「莊獻世子」，並修建了壯麗的顯隆園（水華城）以盡孝思。

「壬午禍變」絕非單純的家庭倫理慘案，而是封建專制體制下，過度扭曲的父權控制、殘酷的朋黨政治以及繼承人危機相互作用下的極致悲劇。英祖以至高無上的君權與極端的手段處理了這場危機，固然保全了王權的延續與世孫的順利繼位，卻也在朝鮮王朝的歷史上，留下了無法抹滅且令人唏噓的血色印記。

Patriarchal Authority, Factional Strife, and Court Tragedy: The Historical Reality of the Eimo Disaster

In 1762 (the 38th year of the reign of King Yeongjo), a horrifying court tragedy unfolded in the Joseon Kingdom. King Yeongjo, the 21st monarch of Joseon, deposed his 27-year-old biological son and heir, Crown Prince Sado (Yi Seon), reducing him to a commoner and locking him inside a narrow wooden rice chest. Denied all food and water amidst the scorching summer heat, the Crown Prince struggled for eight days before dying of starvation. Known in history as the "Eimo Disaster" (or the Rice Chest Incident of 1762), this event stands as one of the most brutal political purges in Joseon history, vividly illustrating the dark convergence of autocratic royal authority, oppressive patriarchal education, and ruthless court factionalism.

1. A Lonely Heir Burdened by Overwhelming Expectations

King Yeongjo was the longest-reigning and longest-lived monarch in Joseon history, heralded for ushering in the prosperous "Yeongjo Restoration." However, this accomplished ruler suffered severe misfortune regarding his offspring. His eldest son, Crown Prince Hyojang, died at a young age, leaving Yeongjo facing a prolonged succession crisis until his royal consort, Lady Yeong, gave birth to his second son, Yi Seon, when the king was 42 years old.

Delighted by the birth of Yi Seon, King Yeongjo immediately declared him the royal heir and officially invested him as Crown Prince at the age of three. Demonstrating exceptional precocity from early childhood, the young prince was burdened with immense expectations. Yet this heavy mantle quickly turned into a childhood nightmare. King Yeongjo subjected the Crown Prince to an extraordinarily severe education, forcing him to study Confucian classics such as the Classic of Filial Piety and the Lesser Learning from a tender age, demanding absolute conformity to scholarly ideals. By age eight, the prince was required to participate in royal ancestral rites, and at age nine, he was married to Lady Hyegyeong. Deprived of a normal childhood in a high-pressure environment devoid of warmth, the young prince developed an intense fear of his father, laying the groundwork for his eventual psychological breakdown.

2. Caught in Factional Warfare and the Strain of Regency

When Crown Prince Sado reached the age of 14, King Yeongjo instructed him to act as Prince Regent, involving him directly in state affairs. Rather than facilitating a smooth succession, this arrangement thrust the young prince directly into the crossfire of court factionalism. At the time, the court was dominated by the rival Noron and Soron factions. King Yeongjo himself had ascended the throne with the crucial backing of the Noron faction, which held sway over the government; however, as regent, Crown Prince Sado pursued a policy of political balance and frequently favored the Soron faction in policy decisions.

This political shift alarmed the hardline leaders of the Noron faction, prompting a wave of slander and secret accusations targeted at the prince. Deep ideological rifts opened between father and son, and King Yeongjo’s harsh reprimands and public displays of distrust drove the prince into severe anxiety and chronic stress. When King Yeongjo’s favored consort later gave birth to a daughter, rumors circulated that elements within the Noron faction sought to replace the Crown Prince altogether. Under relentless external pressure, Sado’s mental stability collapsed, culminating in severe manic depression and bipolar episodes.

3. Escalating Madness and an Irreversible Crisis

As Sado’s psychological condition deteriorated, his behavior grew increasingly violent and uncontrollable. According to The Memoirs of Lady Hyegyeong and the Annals of the Joseon Dynasty, during his bouts of madness, the prince frequently abused and murdered eunuchs and court ladies, and even snuck out of the palace in disguise. In deep emotional anguish, the prince attempted suicide three times by jumping into wells or lakes, only to be rescued by attendants each time.

Following the deaths of Sado’s adoptive mother, Queen Jeongseong, and his step-grandmother, Dowager Queen Inwon—both of whom had historically shielded him—the prince lost his remaining advocates at court. Sado's untamed violent outbursts threatened palace security and pushed King Yeongjo to absolute despair regarding his heir. Meanwhile, Sado’s young son, Yi San (the future King Jeongjo), displayed remarkable intellect and virtue, winning the deep affection of King Yeongjo. To secure the royal lineage and ensure a stable transition of power, King Yeongjo began contemplating the extreme decision of sacrificing his son to preserve his grandson.

4. Tragedy in the Rice Chest and Its Historical Aftermath

In the fifth lunar month of 1762, Crown Prince Sado’s birth mother, Lady Yeong, approached King Yeongjo to report her son’s violent acts, urging the king to take action to save the grand heir, Yi San, and protect the dynasty. Under Joseon law and dynastic precedent, executing the Crown Prince as a criminal would taint his immediate family, stripping young Yi San of his legitimate royal status and risking diplomatic intervention from Qing China.

To eliminate the Crown Prince without invalidating his grandson’s right to the throne, King Yeongjo devised a devastating solution. He ordered a large wooden rice chest brought forth, stripped Sado of his royal title, and locked him inside. The chest was placed in front of Munjeongjeon Hall in Changgyeonggung Palace, with strict orders that no food or water be provided. After eight agonizing days of heat, dehydration, and starvation, Crown Prince Sado perished inside the chest on the first day of the sixth lunar month.

Following his son's death, King Yeongjo was overcome with grief and regret, bestowing upon his deceased son the posthumous title "Sado," meaning "thinking of him with sorrow and grief." Grand Heir Yi San was subsequently adopted as the son of his deceased uncle, Prince Hyojang, preserving his legitimate lineage and allowing him to succeed King Yeongjo as King Jeongjo. Upon ascending the throne, King Jeongjo worked tirelessly to restore his father’s reputation, elevating him to Crown Prince Jangheon and constructing the magnificent Hyeonneungwon tomb complex in his honor.

Conclusion

The Eimo Disaster was far more than a isolated family tragedy; it was a profound historical crisis born of absolute autocratic power, oppressive fatherly control, and ruthless partisan politics. While King Yeongjo used ultimate monarchical force to preserve dynastic continuity and secure his grandson's succession, his actions left an indelible, tragic scar across the history of the Joseon Dynasty.
