History

Jeju Island has been inhabited by modern humans since the early Neolithic period. There is no discovered historical record of the founding or early history of Tamna. One legend tells that the three divine founders of the country—Go (고), Yang (양), and Bu (부)—emerged from three holes in the ground in the 24th century BC. These holes, known as the Samseonghyeol (삼성혈), are still preserved in Jeju City. Until 938 AD, the island was an independent kingdom called Tamna (which means 'island country') when it became a vassal state of Korea under the Goryeo dynasty. In April 1330, in the midst of political purges of the Yuan dynasty, Toghon tomor had been sent in Exile on this remote island, which was then part of the vassal Korean Goguryeo. In 1404, Taejong of Joseon placed the island under firm central control and brought the Tamna kingdom to an end.

In April 1948, it was the site of the Jeju uprising.
