Injong of Goryeo vs Narathihapate

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.

Kublai Khan's Mongol forces invaded the Pagan Empire after King Narathihapate refused to pay tribute. The Mongols defeated the Pagan army and sacked the capital, Bagan. Narathihapate fled south, and the empire collapsed, leading to a period of political fragmentation.

As the Mongol army approached Bagan, King Narathihapate abandoned the capital and fled to the southern city of Prome. His flight demoralized his forces and left the empire defenseless, earning him the epithet 'Taruk-Pye' (the king who fled from the Chinese).

After fleeing to Prome, King Narathihapate was assassinated by his own son, Thihathu, who sought to seize power. The assassination marked the end of the Pagan dynasty and plunged Burma into a period of civil war and fragmentation.
