Sindae

King Sindae (, 89–179; r. 165–179) was the eighth ruler of Goguryeo, the northernmost of the Three Kingdoms of Korea. The Samguk sagi records him as the half-brother of the sixth king Taejo and the seventh king Chadae. Other records indicate he may have been Taejo or Chaedae's son. He tried to stabilize the court by incorporating Chadae's son and other opponents into his administration. To strengthen royal power, he created the supreme ministerial post of guksang(國相), and appointed Myeongnim Dap-bu to the office. The Later Han invaded Goguryeo in the eleventh month of 172, but were destroyed by Myeongnim Dap-bu's army at Jwawon(坐原), gaining success to expand its territory into western side of the kingdom.

Death In 176, he named his second son Nammu as the crown prince (subsequent king Gogukcheon), which consolidated the tradition of patrilineal succession. Sindae died in the twelfth lunar month of 179, at the age of 91.
