Sunjong was the last monarch of Korea, serving as emperor from 1907 until Japan’s annexation of Korea in 1910. His reign marked the final years of the Korean Empire before it was absorbed by Japan.

Early Life and Ascension

Sunjong, born Yi Cheok (이척; 李坧) on March 25, 1874, was the second son of Emperor Gojong and Empress Myeongseong. From an early age, he was destined for the throne, proclaimed Crown Prince of Joseon at just two years old in 1876. Despite his high status, Sunjong’s life was far from easy. Historical records describe him as intellectually impaired, which affected his ability to rule effectively. His childhood was marked by political instability and intense foreign pressure as Japan increased its influence over Korea.

Sunjong’s first marriage was to Empress Sunmyeonghyo of the Yeoheung Min clan, a union arranged to strengthen ties between the imperial family and the powerful Min clan. Tragically, she died young in 1904, suffering from severe depression following the assassination of her mother-in-law, Empress Myeongseong, at the hands of Japanese agents in 1895. Sunjong remarried three years later, this time to Yun Jeung-sun of the Haepyeong Yun clan, who became Empress Sunjeong. Despite these political marriages, Sunjong had no children of his own.

When Gojong declared Korea an empire in 1897, Sunjong was elevated to the position of Crown Prince of the newly formed Korean Empire. He was also appointed Field Marshal of the Imperial Korean Army on June 29, 1898, further solidifying his role as the future ruler. However, this military position was largely ceremonial, and his actual influence over the army was minimal.

Becoming Emperor

Sunjong ascended the throne on July 19, 1907, after his father, Gojong, was forced to abdicate due to Japanese pressure. The coronation took place at Dondeokjeon Hall, but the event was overshadowed by the growing dominance of Japan over Korea. Sunjong was a figurehead with little real power, and his reign was heavily influenced by Japanese authorities.

One of the earliest and most damaging treaties of his reign was the Japan–Korea Treaty of 1907. This treaty effectively turned Korea into a protectorate of Japan, allowing Japanese officials to supervise Korean affairs and appoint their own ministers to key government positions. Sunjong, though the emperor, was reduced to a symbolic figure, while real political control rested in the hands of Japanese authorities.

Japanese Control and Decline of the Korean Empire

During Sunjong’s brief reign, Japan gradually stripped Korea of its sovereignty. In 1907, Japan disbanded the Korean army under the guise of financial constraints, effectively eliminating any possibility of military resistance. By 1909, Japanese influence had spread to the judiciary, with the Japan–Korea Protocol of 1909 eliminating Korea’s judicial autonomy.

Japan’s efforts to consolidate control over Korea culminated in the assassination of Itō Hirobumi, the Japanese Resident-General of Korea, by Korean nationalist Ahn Jung-geun in 1909. Although this event briefly raised hopes for Korean independence, it had the opposite effect. Japan used the assassination as a pretext to accelerate its annexation plans. Pro-Japanese politicians, including Song Byung-jun and Lee Wan-yong, facilitated the annexation by signing the Japan–Korea Annexation Treaty on August 29, 1910.

The treaty marked the formal end of the Korean Empire, dissolving over 500 years of the Joseon dynasty’s rule. Though Sunjong was still emperor in name, the reality was that Japan had absorbed Korea, and he was rendered powerless.

Life After Abdication

Following the annexation, Sunjong and his wife, Empress Sunjeong, were confined to Changdeokgung Palace, where they lived in virtual captivity. The Japanese demoted Sunjong from emperor to the title of “King Yi of Changdeok Palace” (창덕궁 이왕), a symbolic position that stripped him of any real authority. The Japanese maintained the title as a gesture of respect, but it was a hollow honor that masked the reality of Japan’s total control.

Sunjong spent the remainder of his life in isolation. His movements were closely monitored, and he was surrounded by pro-Japanese officials. His health deteriorated, and he became a largely forgotten figure as Japan solidified its control over the Korean Peninsula.

Death and Legacy

Sunjong died on April 24, 1926, at Changdeokgung Palace. His passing triggered an unexpected wave of nationalist sentiment, as many Koreans viewed his death as the end of an era. His state funeral on June 10, 1926, served as a catalyst for the June 10th Movement, a demonstration against Japanese colonial rule. Thousands of Koreans took to the streets to mourn Sunjong and protest Japan’s continued occupation, an indication that despite Sunjong’s powerless position, his symbolic role as the last monarch of Korea still resonated with the Korean people.

Sunjong was buried alongside his two wives, Empress Sunmyeong and Empress Sunjeong, at the imperial tomb of Yureung (유릉; 裕陵) in Namyangju, Gyeonggi Province. The elaborate tomb served as a final resting place for the last monarch of Korea, a somber reminder of the end of Korean sovereignty.

Family and Lineage

Sunjong was born into the prestigious House of Yi, a lineage that had ruled Korea for centuries. His father, Emperor Gojong, was a reformist monarch who tried to modernize Korea and protect it from foreign influence. His mother, Empress Myeongseong, was a powerful political figure who resisted Japanese interference, ultimately paying for her defiance with her life.

Sunjong’s wives, Empress Sunmyeong and Empress Sunjeong, played key roles in his life, although neither bore him children. His adopted son, Yi Jin, died young, leaving no direct heir to continue the royal line. Sunjong’s lack of an heir underscored the finality of the end of the Korean monarchy.

Honors and Recognition

Despite his limited power, Sunjong was awarded numerous honors during his lifetime. He founded the Order of the Auspicious Phoenix (서봉장, 瑞鳳章) in Korea, a distinguished order meant to recognize contributions to the state. He also received prestigious honors from Japan, including the Grand Cordon of the Order of the Chrysanthemum and the Korean Colonization Decoration in 1912. These honors, however, were emblematic of Japan’s dominance over Korea rather than genuine recognition of Sunjong’s authority.

Sunjong’s Place in History

Sunjong’s reign is often remembered as a tragic period in Korean history, where the monarchy became a powerless symbol under Japanese rule. His short and constrained reign illustrates the immense challenges faced by Korea during the early 20th century, as the nation struggled to maintain its independence in the face of foreign aggression.

Though Sunjong himself was unable to resist Japanese domination, his legacy endures as a poignant reminder of Korea’s lost sovereignty and the resilience of the Korean people. His death and the subsequent protests that erupted in its wake demonstrated that Korean nationalism remained strong despite decades of Japanese colonial rule.
