Isabu (Korean: 이사부; Hanja: 異斯夫) was a military general and politician of Silla during the 6th century.
[3] He was the 4th generation descendant of King Naemul, which also provides direct proof that his family name was Kim.
During the reign of Jijeung, Isabu was first appointed as the governor (gunju) of Siljik province (실직주), modern-day Samcheok.
In order to overcome such obstacles and conquer this island nation, Isabu came up with an idea to trick people of Usan-guk into surrendering.
Isabu also subjugated Daegaya that put an end to the Gaya confederacy and thus, consolidated Silla's power on southeastern part of Korea.
