The history of Jeju City is inextricably linked to the centuries-old chronicle of the entire island, which existed as an independent state for a long time. The modern city grew on a site that has been the political and cultural centre of this unique part of South Korea since ancient times.
Foundation and First Mentions
Before the island received its current name, it was known as the Kingdom of Tamna, which means "island country". Although the exact date of the state's founding is unknown, legends date back to deep antiquity. According to the myth of Samseonghyeol ("Caves of the Three Clans"), three demigods emerged from three holes in the ground located in the centre of modern Jeju City to become the progenitors of the island's indigenous population. Archaeological finds made in the Samyang-dong area confirm that large settlements existed here as early as the 3rd century BC.
Key Factors of Development
The development of the city and the island was determined by several key factors. Firstly, geographical isolation from the mainland allowed the Kingdom of Tamna to maintain independence and form a distinctive culture for a long time. Secondly, its advantageous location facilitated the development of maritime trade with the states of the Korean Peninsula, as well as with China and Japan. Politically, the Kingdom of Tamna remained independent until it was incorporated into the Korean state of Goryeo (approximately in the 10th-12th centuries), after which the island received the name "Jeju". Its status was finally consolidated in the early 15th century under the Joseon Dynasty, when Jeju became an important administrative and military centre.
Early Cultural and Economic Features
Initially, Tamna's economy was based on agriculture, fishing, and harvesting seafood. The island's culture developed in isolation, which was reflected even in the local language, which differed noticeably from the languages of neighbouring countries. During the Joseon Dynasty era, the island acquired a new, rather specific function — it became a place of exile for political prisoners and disgraced aristocrats. This, in turn, enriched the local culture, as educated and noble people arrived on the island. Also during this period, the island was used for horse breeding and was known for its tributes to the royal court in the form of local products, such as mandarins and abalone.
