Kyà Âng Taesà Âng (; 1154 â 4 August 1183 was a military official of the mid-Goryeo period who lived from 1154 (the 8th year of King Uijong's reign) to 1183 (the 13th year of King Myeongjong's reign). He became the third dictator of the Goryeo military regime that emerged after the 1170 military coup. At the age of 26, in 1179 (the 9th year of King Myeongjong), he removed the then-powerful Chà Âng Chungbu and seized control, ruling for about four years. His rule is often seen as distinct from those of other military rulers before and after him. Unlike other military leadersâÂÂYi à ¬ibang, Chà Âng Chungbu, Yi à ¬imin, the Ch'oe family rulers, and the final military leaders Kim Chun and Im Yà Ân â who appear in the "Rebels" section of the Goryeosa (History of Goryeo), Kyà Âng Taesà Âng's biography appears in the general biographical section, showing a more favorable evaluation.
Kyà Âng Taesà Âng's family origin (bon-gwan) was Cheongju Kyà Âng clan in the year 1154. He possessed exceptional physical strength and ambition from an early age, caring little for household affairs. An inscription on the Cheongju Yongdusa Temple Iron Flagpole, established in 962 during King Gwangjong's reign, includes the name Kyà Âng Chuhong, a contributor to its construction. This suggests that Kyà Âng Taesà Âng's family had been local elites (hyangni) in Cheongju since early Goryeo. His father, Kyà Âng Chin, was known for his greed, illegally seizing farmland and amassing great wealth.
His family rose to central political prominence by his father Kyà Âng Chin's generation. Kyà Âng Chin was promoted to the second-highest official rank of chi munhasà Ângsa () shortly after Chà Âng Chungbu came to power. According to Kyà Âng Taesà Âng's biography, his father eventually reached the top rank of vice-director of the Secretariat (), though this may have been a posthumous title.
Through his father's rise, the family formed alliances with other powerful families. Kyà Âng Chin married his daughter to General Yi Soà Âng, a key figure in the military coup, and took Kim Chun (who later became a top military ruler) as his son-in-law.
Kyà Âng Chin had been appointed to this post after the military revolt, but his family had already been a prominent military lineage before the revolt. The extent of their influence is evident in the wide range of marital ties with other military families. For example, Kyà Âng Taesà Âng's brother was married to Yi Soà Âng's daughterâÂÂthe man who ignited the military revoltâÂÂand General Son Sà Âk was one of his relatives.
With this background, Kyà Âng Taesà Âng was appointed at 15 years old to the military rank of lieutenant () via a protected appointment. This happened in 1168, and just two years later, the military coup occurred. At 17, Kyà Âng Taesà Âng likely did not participate directly in the coup; there is no record of his actions during this period, making it unclear where he stood. But his father's advancement helped him rise quickly in the military after the revolt. By 1174, he had become a haengsu (military commander), and by 1178, he was promoted to general (changgun), an extremely rapid rise in just ten years. He reportedly harbored resentment toward Chà Âng Chungbu's growing power and contemplated assassinating him but held back due to the risks involved.
His rapid rise was likely related to his role as a commander of the royal guards. After the revolt, the political role of the royal guards greatly expanded, and commanding them almost guaranteed political success. His appointment was likely influenced by his father Kyà Âng Chin's political clout. Kyà Âng Chin, along with Song Kunsu (the son of Song Yu-in, Chà Âng Chungbu's son-in-law), held a senior administrative post. This indicates that royal guard commanders were appointed based on political connections. There are even records of high-ranking military officials competing to have their sons appointed to such roles. Therefore, Kyà Âng Taesà Âng's career was built not on participation in the military revolt but on his prestigious family background.
When his father died, he submitted the land register to the Sà Ân'gun (é¸軠â a military selection authority or office) and did not take any of it for himself, earning a reputation for integrity and honesty.
In 1174 (4th year of King Myeongjong), the king ordered Kyà Âng Taesà Âng, then haengsu, and instruction officer () Yu Kwangyun to play gyeokgu (a traditional polo-like game) and awarded them silk in differing amounts as prizes.
In 1178 (the 8th year of King Myeongjong's reign), a major incident occurred in Cheongju â a violent conflict between local residents and returnees from Kaegyà Âng (the capital). The locals slaughtered most of the newcomers. In response, the Cheongju people residing in the capital recruited a death squad and dispatched them to Cheongju, but they failed, and over 100 were killed. Kyà Âng Taesà Âng, serving as an inspector general () with General Pak Sunp'il (), failed to resolve the conflict and were dismissed from their posts. His resentment toward the regime deepened. Chà Âng Chungbu's regime was losing public support. His son Chà Âng Kyun tried to marry a princess against the king's will, and his son-in-law, Song Yu-in, demoted respected officials out of jealousy. These events alienated many court officials, prompting Kyà Âng Taesà Âng to act.
In September 1179, during a night vigil at the Tripiá¹Âaka assembly (), Kyà Âng Taesà Âng, and Hà  Sà Âng () â trusted by Chà Âng Kyun â killed him inside the palace. This was the signal for Kyà Âng Taesà Âng and a 30-man death squad to storm the palace. They killed high officials and others on sight. King Myeongjong was shocked but calmed once Kyà Âng explained his intentions. The king even served them wine in support. Kyà Âng persuaded the king to dispatch the royal guards, Hà  Sà Âng of the Kyà Âllyong army () and others to arrest Chà Âng Chungbu, his son Chà Âng Kyun, and Song Yu-in thereby seizing power. They were beheaded and their heads displayed in public.
When congratulated by officials, Kyà Âng Taesà Âng reportedly replied, "How can I accept congratulations when the regicide is still alive?" â a reference to Yi à ¬imin, who had killed the former King Uijong. This statement was seen as rejecting not only the military regime but perhaps even Myeongjong's legitimacy. When the king suggested appointing a military official as royal transmitter (), Kyà Âng objected, saying only Confucian scholars should fill that role. Thus, from the beginning, Kyà Âng Taesà Âng presented himself as a restorer of legitimate rule, in contrast to previous military leaders.
He had long resented the abuses of Chà Âng Chungbu, who had seized power during the military revolt, and sought an opportunity to remove him.
Kyà Âng Taesà Âng's decision to remove Chà Âng Chungbu is said to have been triggered by the impeachment of Mun Kà Âkkyà Âm () and Han Munjun by Song Yu-in. This incident left Song Yu-in unable to escape criticism from the court and government officials. Although Kyà Âng Taesà Âng had long contemplated removing Chà Âng Chungbu, he had hesitated until this opportunity arose. It's only natural that he took advantage of the situation. He likely anticipated that removing Chà Âng Chungbu would not put him at a disadvantage and might have expected public opinion and political support to shift in his favor.
Mun Kà Âkkyà Âm and Han Munjun were both civil officials. Therefore, it is reasonable to infer that those who criticized their demotion and turned against Song Yu-in were mostly fellow civil officials, and that their dissatisfaction played a key role in Chà Âng Chungbu's downfall. This situation also raises the question of whether the political influence of the civil officials was still intact at that time. Since high-ranking positions were still largely held by civil officials, this interpretation appears plausible. However, it must also be noted that during Kyà Âng Taesà Âng's rule, in the 13th year of King Myeongjong's reign, a motion was raised to reduce the number of high-ranking civil posts, indicating that the status of civil officials was under threat. In such a climate, it would have been difficult for them to wield political influence. The fact that civil officials held high positions does not necessarily mean they had actual political power. The key to political influence lies in who truly held power. Thus, the dissatisfaction of civil officials likely was not the decisive factor in Chà Âng Chungbu's fall.
Mun Kà Âkkyà Âm, who was impeached by Song Yu-in, had been appointed by Yi à ¬ibang right after the military revolt and had contributed significantly to the establishment of the military regime. He had maintained close ties with military officials for a long time. This suggests that those who were displeased with his impeachment were likely military men rather than civil officials. It may have been precisely because they were military men that they were able to openly show their dissatisfaction toward Song Yu-in, Chà Âng Chungbu's son-in-law.
These military men, resentful of Song Yu-in's overreach, may have supported Kyà Âng Taesà Âng. Even if they did not support him outright, it is clear they did not interfere with his coup. This is evident from the behavior of the Council of Generals () during the coup.
The Council of Generals had emerged as the highest ruling body after the military revolt and handled all major national affairs, including cases of treason. This function remained unchanged during Kyà Âng Taesà Âng's regime. According to historical records, "King Myeongjong was weak-willed and all state affairs were decided by the generals, while the king merely nodded along." These generals clearly referred to members of the Council.
Considering the role and authority of the Council of Generals, if the majority of high-ranking military officials had been unhappy with Kyà Âng Taesà Âng's coup, retribution would have followed. However, no such records exist. Of course, there were some military officials who proposed removing Kyà Âng Taesà Âng, but their opinions were not accepted, indicating they were in the minority. Had the Council of Generals opposed him, his rise to power might not have been possible. In the end, Kyà Âng Taesà Âng's coup succeeded because he had the cooperation or at least the silent approval of many in the Council of Generals.
After becoming the ruling military official, he weakened the Council of Generals, the existing top decision-making body. He continued to influence court decisions, visiting the palace for important matters. Though the king privately feared him, he constantly sent him lavish food, clothing, and treasures. All officials sought his favor, but Kyà Âng refused official posts and remained in his private residence. But lacking a solid power base, Kyà Âng Taesà Âng lived in constant anxiety. Despite having seized power through force, he made efforts to appoint both civil and military officials fairly, which provoked resentment among other military officials and led to frequent conflicts. Though Chà Âng Chungbu's faction was eliminated, military officials who had gained power under the regime openly opposed Kyà Âng. They argued Chà Âng had empowered the military class and that Kyà Âng had killed four top officials overnight.
He formed a private military force of over 100âÂÂcalled the Tobang â to guard him day and night laying the foundation for maintaining his authority. The Tobang was his personal guard, a first-of-its-kind private force. Its members were mostly "Sasa" (death warriors), including the 30 or so warriors he led during the coup. A record states: "At the time, many thieves roamed the capital, calling themselves members of Kyà Âng Taesà Âng's Tobang. When officials arrested and jailed them, Kyà Âng Taesà Âng would release them immediately." This suggests that the Tobang members were effectively criminals disturbing public order. That he organized such individuals into his guard is a serious matter.
These Sasa or "thieves" were likely men who lived off personal martial prowessâÂÂunwelcome in peaceful times but thriving in chaos. Their rise was a product of the military revolt, evident from how such terms proliferated post-revolt. This underscores the era's emphasis on individual martial power. The Tobang also included members of the Kyà Âllyong army. Kyà Âng Taesà Âng had Kyà Âllyong commander Kim Chagyà Âk () oversee the Tobang, indicating that state troops were used as private guards. By organizing this force with death warriors, thugs, and even royal troops, Kyà Âng Taesà Âng violated the existing legal order. The very formation of a private army represents a rejection of institutional normsâÂÂrevealing that he, too, was influenced by the post-revolt changes.
According to records, Kyà Âng Taesà Âng once made long pillows and blankets so his Tobang guards could take shifts sleepingâÂÂand even shared a blanket with them to show his sincerity. That someone from a prestigious family, reportedly longing for "restoration," would sleep alongside ruffians is telling. It suggests he knew he could not rely solely on his own authority and had to conform to the new realities of power.
Given his noble background, Kyà Âng Taesà Âng likely could not tolerate such individualsâÂÂespecially since they had driven the post-revolt changes. Kyà Âng Taesà Âng also rejected those lacking education or strategyâÂÂoften men from humble backgrounds who had risen after the revolt. One example is Yi Yà Ângjin (), who had once made a living fishing but suffered politically under Kyà Âng Taesà Âng. Another was Yi à ¬imin, a towering man of humble origins whom Kyà Âng Taesà Âng declared his intent to eliminate Yi à ¬imin, calling him the king's murderer.
Yi had risen through slaughter during the 1170 coup. When Kyà Âng's coup occurred, Yi panicked and fled to his hometown of Gyeongju to gather troops. Later, while serving on the northern frontier, he mistakenly heard that Kyà Âng had died and rejoiced, saying, "I meant to kill him but someone did it first!" Kyà Âng, upon hearing this, held a grudge, and Yi, fearing for his life, feigned illness and retreated to his hometown, Gyeongju.
Ultimately, though Kyà Âng Taesà Âng declared his intent to punish Yi à ¬imin, he failed to act. He appeared more passive than aggressive toward his enemiesâÂÂlikely because they had grown too powerful. Even during his regime, men like Ch'oe Sebo and Cho Wà Ânjà Âng, who shared Yi à ¬imin's political traits, held high office. Thus, his condemnation of Yi à ¬imin as a regicide and rejection of unlearned men reflect his underlying hostility toward the political rise of the lower-class military elite. But power had already begun to tilt toward those who had played active roles in the military revolt.
Kyà Âng became increasingly brutal and insecure during his rule, that he constantly had people patrol the streets. He dispatched agents to monitor rumors and imprisoning and interrogating people even based on them. He even frequently staged purges and using harsh punishments.
During his time in power, lawlessness spread under the Tobang followers, and frequent uprisings occurred, even by close allies like Hà  Sà Âng and Kim Kwangnip () who had helped him and had played major roles in overthrowing Chà Âng Chungbu's faction who began to abuse their newfound power, resulting in social disorder. In 1181, when Han Sinch'ung (), Ch'ae Injà Âng (), and Pak Tonsun (), who had served as taejà Âng (éÂÂæ£ â a military rank), attempted a rebellion, he exiled them to islands.
Kyà Âng Taesà Âng died young, at 30. After dreaming of Chà Âng Chungbu scolding him with a sword, he fell ill and diedâÂÂunable to overcome his lasting anxiety about his political enemies. His death brought widespread mourning. Since his rule went against the prevailing trends, harsh measures alone could not change the course of history. After Kyà Âng's death, his Tobang was quickly disbanded. Kim Chagyà Âk, its commander, accused its members of plotting rebellion. Under torture, many were executed or exiled. Kyà Âng's faction was completely destroyed.
Fearing Yi à ¬imin might rebel, King Myeongjong sent envoys to placate him and summoned him to the capital, where he eventually succeeded Kyà Âng as military ruler.
A notable fact about Kyà Âng Taesà Âng is that, among all military rulers after the revolt, he is the only one whose biography is not found in the Goryeosa's "Biographies of Traitors," but rather in the general biographies section. All other military rulers before and after him were recorded as traitors. This decision by the compilers of the Goryeosa likely reflects the positive evaluation of him by civil officials of his time. Clearly, they regarded him as distinct from figures like Yi à ¬ibang and Chà Âng Chungbu.
If civil officials viewed Kyà Âng Taesà Âng positively, the military officials likely saw him in a more negative light. The following record reveals his political stance:
This explains why civil officials respected him. The term "restoration" (復å¤) here refers to a desire to return to the pre-revolt state. Thus, Kyà Âng Taesà Âng can be interpreted as someone who rejected the military revolt and the military regime that emerged from it.
Of course, the claim that he held such "restorationist" ideals is likely exaggerated. This was not his own statement but the civil officials' evaluation. It seems they projected their hopes onto him. Still, it's hard to deny that he was dissatisfied with the military revolt and its aftermath.
His disapproval of the military's illegal behavior, which only became possible after the revolt, reveals his discomfort with the resulting societal changes. His resentment of such behavior points to dissatisfaction with the new order.
The Kà Âryosa chà Âryo (Essentials of Goryeo History) offers this evaluation of Kyà Âng Taesà Âng:
This suggests he aimed to restore the pre-military coup order. His actionsâÂÂreturning illegally acquired land, holding Buddhist rites for those killed in the coup and rebellionsâÂÂreflected this intent. Therefore, scholars respected him, and this favorable view continued into the compilation of the Goryeosa, where his biography was placed in the general section, not the rebels' section. However, lacking a strong political base and facing military opposition, he died young and could not sustain his rule.
