King Gwanggaeto
King Gwanggaeto (lit. "king who broadly opened the territory") was the 19th ruler of the ancient Korean kingdom of Koguryo. He is known for leading the kingdom into a great revival and expanding its territory after a period of defeats against outside attackers.
A stele associated with him was discovered in the city of Jí'ān in China's Jilin province near the China-Korea border in 1880.
