Seodongyo

Seodongyo is a 6th-century Korean folk song attributed to Prince Buyeo Seodong, later King Mu of Baekje. The song is significant as the earliest known example of a gagok, a genre of Korean poetry set to music. The lyrics tell a simple story of a young man, Seodong, who is infatuated with Princess Seonhwa. He composes a song about their alleged secret romance and has it sung by children throughout the kingdom. The song's widespread dissemination leads to gossip and eventually forces the king to acknowledge their relationship and arrange their marriage.

The narrative of Seodongyo is preserved in the Samguk Sagi, a historical record of the Three Kingdoms of Korea. The poem itself is short and written in Old Korean. Its enduring legacy lies not only in its lyrical content but also in its innovative method of using popular music and children to spread a message and influence public opinion. Seodongyo is often cited as a testament to the power of song and its role in social and political events in ancient Korea. The story of Seodong and Princess Seonhwa has been retold in various forms, including dramas and literature, solidifying its place in Korean cultural heritage.
