Jumong's kingdom of Goguryeo eventually evolved into a great regional territory with considerable power and influence. Goguryeo existed for 705 years and was ruled by 28 consecutive emperors of the Go Dynasty until it was conquered by the Silla-Tang alliance in 668. Balhae and Goryeo succeeded Goguryeo, and the modern descendants of Jumong still bear his family name of "Go."
In Goguryeo, Jumong was deified into an ancestral deity and he was worshipped in the Temple of King Dongmyeong next to his tomb.
