Adoption of Buddhism in Goguryeo

In 372 CE, the Goguryeo Kingdom formally adopted Buddhism, marking the earliest recorded introduction of the religion to the Korean Peninsula. This event took place during the reign of King Sosurim, a period characterized by internal reforms and external pressures that shaped the kingdom’s political and cultural direction. According to historical records, Buddhism was introduced to Goguryeo by the monk Sundo, who was sent from the Former Qin state in China. His arrival at the Goguryeo court brought Buddhist texts and images, which were received by the king and integrated into the state’s cultural framework. In the same year, King Sosurim ordered the establishment of the first Buddhist temples, including Seongmunsa and Ilbullansa, providing institutional support for the new religion. The adoption of Buddhism coincided with broader state reforms under King Sosurim. In 372 CE, Goguryeo also established a national Confucian academy known as the Taehak, aimed at educating the elite in governance and administration. These developments indicate a deliberate effort to strengthen state structures through both ideological and institutional means. Buddhism gradually spread beyond the royal court into wider society, influencing art, architecture, and spiritual practices. Its introduction in 372 CE laid the foundation for its continued role in Korean history, eventually becoming a major cultural and religious force across the peninsula.
