Isabu

Isabu (Korean: 이사부; Hanja: 異斯夫) was a military general and politician of Silla during the 6th century. According to Samguk Sagi, he is the fourth generation descendant of Naemul of Silla. He was also known as Taejong. He is best remembered today for his role in subjugating the island nation of Usan-guk. Usan-guk is the modern-day Ulleungdo, an island located in Sea of Japan (East Sea). There is a dispute regarding his surname, as his family name is written as Kim in the Samguk Sagi. He was the 4th generation descendant of King Naemul, which also provides direct proof that his family name was Kim. But in Samguk Yusa, his name is Park I-Jong (朴伊宗).
