King Yejong of Goryeo

King Yejong actively promoted Daoism, establishing the Bokwon-gung Daoist temple in the capital. He personally participated in Daoist rituals and invited Daoist priests from Song China, integrating Daoist practices into state ceremonies alongside Buddhism.

Despite his Daoist interests, King Yejong continued to patronize Buddhism. He sponsored the construction of Buddhist temples and supported the printing of sutras. This dual patronage reflected the syncretic religious environment of Goryeo.

King Yejong established a dedicated office for compiling national history. This office was tasked with collecting records and writing the official history of Goryeo, continuing the tradition of historical scholarship and preserving state records.

King Yejong sent a diplomatic mission to the Song court, seeking to strengthen cultural and political ties. The mission brought back books, musical instruments, and knowledge of Song court rituals, influencing Goryeo's court culture.
