An Yong-bok was a Korean fisherman who became a defender of Korea’s territorial rights in the late 17th century. He played a crucial role in asserting Korea’s claim over Dokdo, a small group of islets in the East Sea. His story is about courage, diplomacy, and the fight for sovereignty.
Many people see him as a simple fisherman, but his actions proved he was much more. He understood diplomacy, stood up to the Japanese, and defended his country’s territorial rights. His efforts helped shape Korea’s historical claim to Dokdo, which remains a significant issue today.
Early Life of An Yong-bok
An Yong-bok was born in Dongnae, which is now part of Busan, South Korea. Not much is known about his early years, but we do know that he worked as an oarsman in the Korean navy. This experience helped him understand maritime affairs and territorial boundaries.
An also learned Japanese while interacting with traders at Waegwan, a trading post in Busan. His ability to speak Japanese would later play a key role in his efforts to defend Korea’s sovereignty over Ulleungdo and Dokdo. Seeing Japanese fishermen trespassing in Korean waters made him determined to take action.
The 1693 Incident: Capture and Diplomacy
In 1693, An Yong-bok and about 40 other Korean fishermen were fishing near Ulleungdo. Suddenly, Japanese fishermen captured them and took them to Tottori, Japan. The Japanese believed Ulleungdo and Dokdo belonged to them and didn’t want Koreans fishing in the area.
An did not remain silent. Despite being a prisoner, he boldly protested to Japanese officials, stating that Ulleungdo and Dokdo were Korean territories. His courage caught the attention of the Japanese authorities, and his case was reported to the central government in Edo (now Tokyo). Eventually, An and another fisherman, Pak Eo-dun, were released and sent back to Korea.
This incident sparked diplomatic discussions between Korea and Japan. The Korean government formally protested, and Japan later acknowledged that Ulleungdo was Korean territory. However, Japan did not clearly address Dokdo at the time, leaving the issue unresolved.
The 1696 Incident: A Direct Confrontation

Three years later, in 1696, An Yong-bok returned to Ulleungdo. This time, he confronted Japanese fishermen directly, telling them to leave. He claimed that not only Ulleungdo but also Dokdo belonged to Korea. An even took a group of Japanese fishermen to Japan’s Oki Islands, where he protested to local officials about the illegal fishing activities.
To strengthen his argument, An presented a document, which he claimed was an official Korean government order proving Korea’s sovereignty. Although some historians believe the document was forged, his actions had a significant impact. The local Japanese officials took his protest seriously and sent reports to their superiors.
As a result of An’s bold actions, the Japanese Shogunate issued a decision in 1696, banning Japanese fishermen from Ulleungdo. This confirmed Korea’s claim over the island. However, Dokdo was not specifically mentioned in the ruling, leading to further disputes in later years.
Japan’s Recognition of Korean Sovereignty
After the 1696 confrontation, Japan’s Shogunate government ordered the Tsushima domain, which handled foreign affairs with Korea, to inform the Korean government that Japan would no longer send fishermen to Ulleungdo. This was a significant diplomatic victory for Korea.
The Korean government took this as proof that both Ulleungdo and Dokdo belonged to Korea. Since Dokdo is geographically close to Ulleungdo and was used as a fishing ground by Koreans, it was considered part of Korean territory. An Yong-bok’s actions played a major role in reinforcing Korea’s historical claim to these islands.
The Historical Significance of An Yong-bok
An Yong-bok’s courage and persistence made him a key figure in Korea’s territorial history. His efforts helped establish a clear historical record that Korea had long considered Ulleungdo and Dokdo as part of its territory.
Although An was just a fisherman, his actions had lasting consequences. His reports and protests were recorded in both Korean and Japanese documents, providing strong historical evidence of Korea’s sovereignty over the islands. Today, these records are often cited in discussions about Dokdo’s territorial status.
The Modern Significance of Dokdo

Dokdo remains a sensitive issue between Korea and Japan. The islets are currently administered by South Korea, but Japan continues to claim them as its territory. The dispute has led to diplomatic tensions over the years.
For South Koreans, Dokdo is more than just a group of small islands. It symbolizes Korea’s fight against foreign aggression and its right to defend its land. The South Korean government actively promotes education about Dokdo, and the Korean Coast Guard maintains a presence on the islets.
An Yong-bok’s story is often taught in schools as an example of national pride and resistance. His legacy continues to inspire Koreans today, reminding them of the importance of protecting their territorial rights.
Conclusion
An Yong-bok’s bravery and determination made him a national hero. He stood up to Japanese fishermen, protested to Japanese officials, and helped establish Korea’s historical claim to Dokdo. His story is a powerful reminder that even ordinary people can make a big difference in defending their country.
Today, Dokdo remains an important part of Korea’s identity, and An Yong-bok’s legacy continues to be honored. His actions in the late 17th century set a precedent for Korea’s continued defense of its territorial rights. Through his courage and determination, he ensured that future generations would remember the significance of Dokdo in Korean history.
