The Samguk Sagi records the early Silla Gabae contest linked with the historical background of Chuseok.
Compiled by Kim Busik and completed in 1145, the Samguk Sagi is the oldest surviving official Korean history. It presents accounts of the Three Kingdoms—Silla, Goguryeo, and Baekje—and includes material about Silla court traditions.
Its account of Gabae describes a contest associated with women divided into groups and competing in textile work over an extended period. The event is often discussed as an early historical predecessor of customs later connected with Chuseok.
The Samguk Yusa is another important medieval Korean work, but it is a different text, compiled later and shaped more by legends and Buddhist stories. The two titles are therefore easy to mix up when discussing early Korean history.
