Yi Mun-jin compiles the Sinjip
Under King Yeongyang, the Taehak scholar Yi Mun-jin condensed the 100-volume Yugi, Goguryeo’s early history, into the five-volume Sinjip.
The Samguk sagi records that in 600, the 11th year of King Yeongyang, the Taehak scholar Yi Mun-jin was ordered to abridge the old history into the five-volume Sinjip. When writing was first used early in the kingdom, someone had recorded events in 100 volumes called the Yugi; the Sinjip condensed it.
Neither the Yugi nor the Sinjip survives. Compiled as the wars with Sui began (598), the Sinjip is seen as an effort to set the kingdom’s past in order and strengthen royal authority and unity.
