Empress Gi

Gi came from Goryeo aristocracy and entered the Mongol court as a concubine to Toghon Temür in the early 14th century. She bore him a son, Biligtü Khan, who would later rule as emperor of the Northern Yuan. As the dynasty frayed, Gi tightened her grip — by its final years she held de facto imperial authority, steering the realm economically and politically while the empire crumbled around her. She died in 1369, having outlasted the Yuan itself.
