다국어 초록 (Multilingual Abstract)

Lee Ta-in was the Chaek Castle castellan at the end of the Goguryeo. In the meantime, various opinions have been raised about his ethnic origin. In this article I examine the existence of the Lee family in the Goguryeo to investigate the ethnic origin of the Lee Ta-in. In the process, I prove that there existed last name Lee in Goguryeo by paying attention to the existence of Lee Moon-jin who made a 『Sinjip』 by the King Yeongyang order in the 600th year and last name Lee in Balhae.
And a comparison of the characteristics of Tang`s give last name Lee and displaced people of Goguryeo of last name Lee who were active in the Tang proved that there existed a unique give last name Lee in Goguryeo. Based on this analysis, I analyzed the phrases written in 「Lee Ta-in`s Epitaph」 and analyzed the relationship between Goguryeo and Malgal, and confirmed that Lee Ta-inwas an Goguryeon who was give last name Lee from Goguryeo Finally it paid attention to revolution of Yeon Gaesomun which originated in 642 about the Background awarded to Chaek Castle castellan of Lee Ta-in. In comparison with the Go Jil family, I could deduce that Lee Ta-in family was able to receive the last name Lee because the Lee Ta-in family established considerable achievements in the revolution of the Yeon Gaesomun.
