Tamna (Korean: 탐라; Hanja: 耽羅) was a kingdom based on Jeju Island from ancient times until it was absorbed by the Korean Joseon dynasty in 1404, following a long period of being a tributary state or autonomous administrative region of various Korean kingdoms. The Go (Jeju) clan is the family name of the Lord (Korean: 성주; Hanja: 星主; RR: Seongju), that ruled West Tamna over 400 years. The Moon (Nampyeong) clan is the family name of the Prince (왕자; 王子; Wangja), that ruled East Tamna for 400 years.
