Eric I of Brunswick vs King Yejong of Goryeo

Eric I inherited the Duchy of Brunswick-L

Eric I participated in the Hildesheim Diocesan Feud, a conflict between the Bishop of Hildesheim and the nobility of the region. He fought on the side of the bishop, but the war ended with a compromise that reduced the bishop's power.

Eric I served in the imperial army of Charles V, participating in campaigns against the French in Italy and the Ottoman Empire. His service strengthened his ties to the Habsburgs and brought him imperial favor.

Eric I initially resisted the Reformation but eventually allowed Lutheran teachings in his territories under pressure from the Protestant estates. This move was partial and inconsistent, leading to religious tensions in his duchy.

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.
