Myeongnim Dap-bu was a
Joui Seonin () of the Yeonna province of
Goguryeo. He rose through the ranks during
King Taejo's reign, and was in the courts by the time of Taejo's death. When Chadae rose to the throne in 146, Myeongnim Dap-bu faced many challenges and suffered under the tyrant's reign. Finally, in 165, during the 20th year of
King Chadae's reign, Myeongnim Dap-bu led an army and assassinated the king with the support of some of the nobles and court officials. Aged 99, Myeongnim Dap-bu took control of the Goguryeo government. He invited
Prince Go Baek-go, the younger brother of King Taejo, to become the next king. Go Baek-go was proclaimed the 8th King of Goguryeo during that year, and Myeongnim Dap-bu was given the position of
Guksang (국상, 國相, Prime Minister), and became the first to receive the title in the history of
Goguryeo. Myeongnim Dap-bu served faithfully under the new king, and defeated Han Chinese forces at the Battle of Jwawon. == Death and Accomplishments ==
