Injong of Goryeo

The Buddhist monk Myocheong led a rebellion in Pyongyang, advocating for moving the capital and attacking the Jurchen Jin dynasty. King Injong initially supported the plan but later opposed it, leading to a three-year revolt that was crushed by the general Kim Bu-sik.

General Kim Bu-sik, acting on Injong's orders, besieged and captured Pyongyang, ending the Myocheong rebellion. The victory strengthened the authority of the civil bureaucracy over military and religious factions, but also deepened regional tensions.

Injong oversaw the compilation of a new legal code based on Tang and Song Chinese models. The code standardized administrative procedures and criminal law, but its implementation was uneven due to aristocratic resistance.
