In 933, King Taejo of Goryeo was conferred the title of King of Goryeo (高麗國王) by the Emperor Mingzong of Later Tang. Prior to its capitulation to the Yuan dynasty, imperial designations and terminology were widely used by the Goryeo dynasty domestically. Its rulers claimed to be the Son of Heaven, as did Chinese emperors. King Gyeongsun of Silla addressed King Taejo of Goryeo as the Son of Heaven when he surrendered. Even though the Song dynasty, the Liao dynasty and the Jin dynasty were well-informed of Goryeo's use of imperial titles, all three Chinese dynasties tolerated such practice.
