King Taejo of Goguryeo (Claimed AD 47–165 r. 53–146) was the sixth monarch of Goguryeo, the northernmost of the Three Kingdoms of Korea. He is sometimes called Taejo the Great. He rose to the throne following the assassination of King Mobon. Under his reign, the young state expanded its territory and developed into a centrally ruled kingdom. His 93 year reign is thought to be the second longest of any monarch in the world. Note that this long of a reign would make him older than any verified men, as well as surpassing any currently alive humans.
