History of Cheju-do

n 1105 (King Sukjong's 10th year), the Goryeo court abolished the name Takna which had to this time been used and from that year on, the island was known as "Tamna-gun" (district) and Goryeo officials were sent to handle the affairs of the island.

Tamna-country was changed to Tamna-county in 1153 during the reign of King Uijong and Choi Cheok-kyeong was posted as Tamna-Myeong or Chief of Tamna. In 1121 during Huijong's reign, Tamna was renamed "Jeju" and the posts of Judiciary were established on the island.

In 1271, General Kim Tong-jeong escaped with what remained of his Sambyeolcho force from Jindo and built the Hangpadu Fortress at Kwiil-chon from where they continued their fight against the combined Korean government-Mongolian army but within 2 years, faced by an enemy army of over 10,000 troops, the Sambyeolcho was annihilated.
