Korean Kings Family Tree

Korea's monarchy developed through four major historical stages: the kingdom of Silla, the kingdom of Goryeo, the kingdom of Joseon, and the short-lived Korean Empire of the early 20th century. The royal family tree places Korean monarchs alongside Chinese emperors and Japanese emperors to illustrate their overlapping histories.

The Korean Peninsula was originally divided among three dominant kingdoms: Goguryeo, Baekje, and Silla. These kingdoms competed for territory and power during approximately the first six or seven centuries of the Common Era, alongside a fourth, less dominant kingdom.

Silla unified much of the Korean Peninsula during the 660s CE. Under King Munmu, Silla conquered its principal rivals and established the first major period of Korean political unification.

King Munmu belonged to the Kim royal dynasty. Two queens who ruled Silla shortly before unification also belonged to the Kim dynasty, although they came from different branches of the family.

Queen Seondeok was the first female monarch in Korean history. Her reign belonged to a wider period in East Asian history when women also occupied sovereign positions in China and Japan.

China and Japan also experienced female sovereignty during this period. The presenter notes that China's first female monarch appeared in the same century as Queen Seondeok, while Japan had already experienced female rule earlier.

Silla's unification depended partly on military assistance from China's Tang dynasty. Tang China was one of East Asia's dominant powers and was experiencing a period often regarded as a golden age of Chinese civilization.

Silla and Tang China became adversaries after their initial cooperation. Once Silla emerged as the dominant Korean kingdom, conflict developed between the former allies over control of the peninsula.

Silla successfully resisted Chinese domination and maintained its monarchy. The presenter argues that a successful Tang conquest could have absorbed Korea more completely into Chinese political and cultural history, potentially changing the development of a distinct Korean identity.

Silla's Kim dynasty continued ruling after unification. Although succession passed between different family branches, the kingdom retained a recognizable royal lineage for centuries.

King Seongdeok is associated with one of Korea's famous historical bells. The Bell of King Seongdeok, named in his honor, weighs approximately 19 tons.

King Seongdeok and Queen Seondeok were different monarchs. Their similar names can cause confusion, particularly because both belonged to the Silla period.

King Munmu's direct male lineage eventually became extinct. King Aegong is identified as the last male-line descendant of Munmu's branch and was assassinated.

The Silla throne passed to another branch of the Kim dynasty. The presenter associates this transition with King Wonseong, whose family branch subsequently dominated the monarchy for more than a century.

Korea fragmented again around the year 900. Silla's decline contributed to the emergence of the Later Three Kingdoms period, during which the peninsula was once again divided among competing states.

The Later Three Kingdoms period was relatively brief. A new kingdom, Goryeo, emerged as the dominant power and reunified the country.

The modern name Korea derives from Goryeo. The kingdom's name became the historical basis for the name by which Korea is internationally known.

King Taejo founded the Goryeo monarchy. He established the Wang dynasty, which replaced Silla's ruling Kim dynasty.

Goryeo's consolidation involved the defeat of Silla's final monarch. The presenter identifies this transition as the decisive replacement of Silla by the new Wang dynasty.

Goryeo achieved a more complete Korean unification than Silla. The presenter distinguishes the earlier Silla unification from Goryeo's more comprehensive integration of the peninsula.

Korea remained broadly unified for more than a thousand years after Goryeo's consolidation. The presenter traces this continuity through successive dynasties until the establishment of separate North and South Korean states in 1948.

Goryeo broadly coincided with China's Song dynasty. Just as Silla's principal historical period overlapped with Tang China, Goryeo's development is placed alongside the Song era.

The Goryeo period is described as a golden age of Korean civilization. Buddhism flourished and became particularly prominent in the kingdom's cultural and religious life.

A military coup transformed Goryeo's political system during King Uijong's reign. Military leaders removed Uijong and replaced him with his brother, King Myeongjong.

King Myeongjong became a ruler controlled by military leaders. Although the monarchy continued formally, the coup transferred effective political authority to the military.

Four successive Goryeo kings effectively ruled as puppets. Powerful military commanders exercised real authority while kings retained their ceremonial and dynastic positions.

The Choe family became particularly influential during Goryeo's military dictatorship. Members of this family were among the powerful figures who controlled government behind the monarchy.

Goryeo's military government developed around the same time as Japan's first shogunate. The presenter compares the two systems because both involved military leaders exercising political power while hereditary sovereign institutions continued to exist.

The Mongol Empire became a major threat to Korea during the 13th century. Mongol expansion devastated large parts of Asia and fundamentally changed the political balance between Korea and China.

The Mongols conquered China and established the Yuan dynasty. Their conquest placed China under a new imperial house connected to the Mongol ruling family.

Goryeo avoided formal incorporation into the Mongol Empire. Unlike China, Korea was not officially conquered and absorbed into the empire in the manner described by the presenter.

Goryeo instead accepted Mongol overlordship. Through political agreements and concessions, the Korean monarchy preserved its formal existence while becoming effectively subordinate to Mongol power.

A Goryeo king was required to marry a daughter of Kublai Khan. This marriage established a direct dynastic connection between Korea's Wang dynasty and the Mongol imperial family.

Subsequent Goryeo kings inherited ancestry from both Kublai Khan and Genghis Khan. Because Kublai was a descendant of Genghis Khan, the marriage connected later Korean monarchs genealogically to both rulers.

Marriage with Mongol women became a recurring feature of Goryeo's royal succession. Several kings during the period married Mongol wives, strengthening the dynastic relationship between the Korean and Mongol ruling houses.

Mongol political decline helped create the conditions for another Korean dynastic change. Developments affecting the Yuan dynasty eventually contributed to the circumstances surrounding Goryeo's collapse.

The Black Death is identified as one major historical development during this transition. The presenter notes that the pandemic is thought to have originated in Asia but acknowledges that its specific impact on countries such as Korea is poorly documented.

China's Red Turban rebellions occurred during the broader period of Mongol decline. These uprisings contributed to the Yuan dynasty's overthrow and its replacement by the Ming dynasty.

The rise of Ming China created a serious foreign-policy crisis for Goryeo. King U ordered his leading general to launch a preemptive military attack against China.

King U's general considered the proposed attack unwise. Instead of carrying out the invasion, he turned against the king and seized control of the Korean government.

King U was deposed and replaced by his ten-year-old son, King Chang. The general initially maintained the existing royal dynasty rather than immediately taking the throne himself.

King U and King Chang were both assassinated approximately one year later. Their removal eliminated the father and son from the immediate succession.

A distant royal relative was installed after the deaths of U and Chang. His reign was short, and he was eventually deposed as well.

The general who had seized control ultimately became king himself. He founded a new dynasty under the royal name Taejo of Joseon, ending Goryeo's Wang dynasty.

The replacement of Goryeo by Joseon changed Korea's ruling family. The Wang dynasty gave way to the Yi dynasty, whose descendants would occupy the Korean throne for the remainder of the country's monarchical history.

The new dynasty also changed the kingdom's name. Goryeo became Joseon, also commonly rendered Choson or Chosŏn.

Joseon and Choson refer to the same kingdom. The presenter notes that older English-language maps often use the spelling beginning with CH, while modern spelling commonly begins with J.

Joseon promoted Confucianism as a leading political and intellectual philosophy. This contrasted with Goryeo's stronger association with Buddhism.

Both Goryeo and Joseon began with monarchs called Taejo. The shared title can be confusing because the two founders belonged to different dynasties and historical periods.

Taejo means “great ancestor.” The title recognizes the monarch's position as the founder of a ruling dynasty rather than indicating that the two kings were the same person.

Taejo of Joseon had eight sons, creating a difficult succession problem. He was uncertain which son should inherit the throne.

The future King Taejong was regarded as the most capable of Taejo's sons. Nevertheless, the prime minister persuaded Taejo to appoint a different son as successor.

The prime minister subsequently plotted to have the future Taejong killed. Taejong learned of the conspiracy and acted against those he believed threatened him.

Taejong had the prime minister and two of his own brothers killed. These killings formed part of the violent struggle over succession within Joseon's founding royal family.

Taejo became deeply distressed by the conflict among his sons. He abdicated rather than continue ruling amid the family's violent political struggles.

King Jeongjong succeeded Taejo but ruled only briefly. His accession temporarily postponed Taejong's eventual inheritance.

Taejong ultimately became king despite the earlier attempt to exclude him. The succession struggle ended with the son originally regarded as the most capable gaining the throne.

Taejong strengthened the monarchy into an effectively absolute institution. The presenter characterizes him as a harsh ruler who greatly expanded royal authority.

Taejong ruled for approximately eighteen years and introduced extensive reforms. His reign established a stronger and more centralized foundation for Joseon's monarchy.

Taejong voluntarily stepped aside in favor of his son Sejong. This transfer brought to power the monarch whom the presenter describes as Korea's greatest king.

King Sejong is widely celebrated for his achievements in government and national development. He successfully managed domestic administration and foreign relations while encouraging scientific, technological, and educational progress.

Sejong's most famous accomplishment was creating the Korean writing system, Hangul. The presenter credits him with inventing its characters and the system through which they represent the Korean language.

Hangul is regarded as an unusually sophisticated writing system. The presenter notes that many linguists consider its design among the most ingenious writing systems ever developed.

Sejong's son Munjong inherited the throne but was seriously ill. Munjong died after a reign of approximately two years.

Munjong's death brought Sejong's young grandson Danjong to the throne. Danjong's youth left him vulnerable to powerful relatives.

Danjong was overthrown by his uncle Sejo. Sejo seized the throne and later had the deposed young king killed.

Sejo's son Yejong succeeded him but also experienced a short reign. Yejong died at approximately twenty years old.

The throne then passed to Yejong's nephew, King Seongjong. Seongjong ruled considerably longer, and the kingdom prospered during his reign.

King Yeonsangun became notorious for violent, cruel, and selfish conduct. The presenter identifies him as one of the least popular monarchs in Korean history.

Court officials organized Yeonsangun's removal. Their conspiracy succeeded, and his brother Jungjong was placed on the throne.

Jungjong was considered an improvement over Yeonsangun. However, he frequently operated under the influence of powerful individuals at court.

Jo Gwang-jo was an influential figure during Jungjong's reign. He became particularly associated with reforms inspired by Confucian principles.

Jungjong was succeeded by his son Injong. Injong's reign was short.

Another son of Jungjong subsequently inherited the throne. He became king at a relatively young age and ultimately died without heirs.

The succession then moved to a nephew, King Seonjo. His accession reflected the need to look beyond the immediate father-to-son succession.

Seonjo ruled for a long period but faced severe national crises. Among the most consequential was a major Japanese invasion of Korea.

Japan's invasion lasted approximately six years. The conflict subjected Korea to a prolonged military struggle involving foreign armies.

Ming China assisted Korea against the Japanese invasion. With Chinese support, Korean resistance successfully prevented Japan from maintaining its conquest.

Japanese forces eventually withdrew from Korea. The presenter identifies the withdrawal as the outcome of Korea's successful resistance with Ming assistance.

Seonjo was succeeded by his son Gwanghaegun. His reign ended when his nephew Injo removed him through a coup.

King Injo inherited a kingdom threatened by major changes in China. The Ming dynasty was increasingly challenged by the rising Qing dynasty.

The Qing dynasty originated among the Manchus. The presenter explains that the Qing is sometimes called the Manchu dynasty because its ruling people came from Manchuria, north of China proper.

The Qing dynasty ultimately defeated and replaced the Ming dynasty. This transition shifted imperial power in China to the Manchu ruling house.

Qing forces also defeated Joseon Korea. The Korean monarchy faced military defeat as the Manchu empire consolidated its regional authority.

Korea was not annexed into the Qing Empire. Joseon survived as a separate kingdom with its own monarchs and political institutions.

Joseon nevertheless became subordinate to Qing China. The presenter describes its position as that of a vassal state required to pay tribute and comply with Chinese demands.

Qing domination was followed by approximately two centuries of relative peace in Korea. The presenter identifies this stability as one benefit of the arrangement, despite the kingdom's reduced freedom of action.

Korea experienced renewed cultural and political development during the reigns of Yeongjo and Jeongjo. The two monarchs were grandfather and grandson, and their long reigns are associated with a period of renaissance.

European powers became increasingly influential in East Asia during the later Joseon period. Their growing involvement introduced additional pressures on established regional political systems.

Korea initially pursued a policy of isolation from foreign influences. The presenter compares this approach with Japan's attempts to restrict outside involvement.

Korea's isolation weakened during the middle of the nineteenth century. Increasing foreign pressure eventually made the traditional policy difficult to maintain.

The direct male lineage of King Yeongjo eventually became extinct. The dynasty had to search much further back through its family tree to identify a suitable successor.

Gojong inherited the throne through a distant branch of the royal family. He became the last monarch to rule specifically as king of Joseon.

Gojong was a contemporary of Japan's Emperor Meiji. Their reigns overlapped during a period when East Asia was undergoing major political and technological changes.

Emperor Meiji transformed Japan into a modern industrial power. The presenter emphasizes Japan's industrial development and creation of an advanced military as particularly important changes.

Korea and Japan initially developed relatively peaceful trading relations during the reigns of Gojong and Meiji. Their relationship was not immediately characterized by open warfare.

Japan's growing economic interests in Korea increased political tensions. The presenter connects Japan's expanding commercial involvement with its subsequent military intervention in the peninsula.

Korea remained formally subordinate to China when Japan challenged Chinese influence. This relationship made Korea a central issue in the rivalry between the two powers.

Japan and China went to war in 1894 primarily over Korea. The presenter identifies competition for influence over Korea as the central issue driving the conflict.

Much of the fighting in the Sino-Japanese War took place in Korea. The peninsula became a major battlefield in the struggle between China and Japan.

Japan defeated China and displaced its influence over Korea. The presenter characterizes the outcome as Korea effectively exchanging Chinese overlordship for Japanese domination.

The presenter uses the word “vassal” loosely when describing Korea's changing status. Korea's relationships with China and Japan involved different legal and political arrangements, rather than one identical form of dependency.

Korea declared itself an empire after escaping China's former overlordship. The change was intended to establish a higher and formally independent sovereign status.

King Gojong became Emperor Gojong. The creation of the Korean Empire changed the monarch's title while preserving the existing royal family.

The Korean Empire survived for only a short period. Its formal imperial status did not prevent Japan from gradually increasing control over the country.

Japan's victory in a subsequent war against Russia strengthened its position in Korea. The presenter links that victory to Japan's ability to establish a formal protectorate over the Korean Empire.

Japan assumed the official role of Korea's protector. The arrangement placed Korea under Japanese political control despite the continued existence of its imperial monarchy.

Japan forced Emperor Gojong to abdicate. His removal demonstrated the extent to which Korean imperial succession had become subject to Japanese power.

Gojong was replaced by his son Sunjong. Sunjong became Korea's final reigning emperor.

Sunjong's reign was brief because Japan abolished Korean sovereignty. In 1910, Japan formally annexed Korea.

The annexation of 1910 incorporated Korea into the Japanese Empire. Unlike the earlier tributary and protectorate relationships, annexation ended Korea's separate status as a sovereign kingdom or empire.

Japanese colonial rule continued until the end of the Second World War. Korea remained under Japanese rule until Japan's defeat in 1945.

Korea subsequently divided into two separate states. The presenter identifies 1948 as the decisive year in which North Korea and South Korea emerged as separate republics.

Neither North Korea nor South Korea retained the monarchy. The former Korean royal family lost its position as the country's ruling institution.

Numerous descendants of Emperor Gojong survived after the monarchy's abolition. Consequently, a hypothetical restoration would involve choosing among living members of the former imperial family.

Yi Seok is identified as the generally recognized head of the former Korean royal house at the time of the presentation. His position concerns dynastic representation rather than any actual authority over Korea.

Yi Seok is a grandson of Emperor Gojong. His father was Yi Kang, a younger brother of Korea's last emperor, Sunjong.

Yi Seok was approximately 77 years old when the episode was produced. The age is a detail reported at the time of the presentation, not necessarily his current age.

Yi Seok had no sons and therefore faced a succession question. His lack of a male heir influenced his decision about who should follow him as head of the family.

Yi Seok designated Andrew Lee as his successor. Andrew Lee is described as an American citizen of Korean descent.

Andrew Lee's precise genealogical relationship to the Yi dynasty was not established in the presentation. The presenter explicitly acknowledged uncertainty about how Lee was related to Korea's former royal family.

Andrew Lee was presented as a prospective successor to the former royal house, not as a reigning monarch. His status depended on Yi Seok's designation within a family that no longer governed Korea.

The question of who would become king if Korea restored its monarchy remains hypothetical. The episode identifies a claimed dynastic succession but does not establish that either Korean republic recognizes a successor or intends to reinstate royal government.

Korea's royal history illustrates repeated changes in ruling families without the permanent disappearance of monarchy. Silla's Kim dynasty gave way to Goryeo's Wang dynasty, which was replaced by Joseon's Yi dynasty; the Yi family then continued into the Korean Empire.

Military intervention repeatedly determined Korean royal succession. Important examples include Goryeo's military coup against Uijong, the overthrow of King U, Taejong's violent rise within Joseon, Sejo's seizure of Danjong's throne, the removal of Yeonsangun, and the coup against Gwanghaegun.

Foreign powers shaped Korean monarchy through several distinct forms of influence. Tang China assisted Silla's unification before becoming its adversary; the Mongols secured Goryeo's submission and royal marriages; Ming China aided Korea against Japan; Qing China imposed tributary obligations; and Japan eventually replaced indirect domination with annexation.

Royal marriages were particularly important to Goryeo's relationship with the Mongol Empire. Marriages linking the Wang family with Kublai Khan's descendants preserved the Korean monarchy while integrating its later rulers into the Mongol imperial family tree.

Religion and philosophy distinguished Korea's successive dynastic periods. Goryeo became strongly associated with Buddhism, whereas Joseon promoted Confucianism as a foundation of government and elite political thought.

Several Korean monarchs shared similar or identical royal names despite belonging to different generations or dynasties. Particularly important distinctions include Queen Seondeok versus King Seongdeok, the two dynastic founders called Taejo, and the later Joseon monarchs whose names share common Korean syllables.

Korea's monarchy ended through foreign annexation rather than the voluntary establishment of a republic. Japan's incorporation of Korea in 1910 ended the imperial state, while the separate republican governments emerged only after Japanese rule ended and the peninsula was divided.
