Chlothar II vs King Injong of Goryeo

Chlothar II's forces defeated the combined armies of Brunhilda and Sigebert II near the Aisne River. The battle was decisive, leading to the collapse of Austrasian resistance and allowing Chlothar to reunite the Frankish kingdoms.

Chlothar II defeated Brunhilda and her grandson Sigebert II at the Battle of the Aisne, capturing and executing Brunhilda. He then united Neustria, Austrasia, and Burgundy under his sole rule, becoming the sole king of the Franks.

After his victory, Chlothar II ordered the execution of Brunhilda, the aged queen of Austrasia. She was tortured for three days, then tied to a wild horse and dragged to her death. This act ended the long feud between the Neustrian and Austrasian branches.

Chlothar II issued the Edict of Paris, a major reform that granted concessions to the nobility and the Church. It limited royal power by confirming the rights of bishops and nobles, and established that counts should be appointed from the local aristocracy.

King Injong's early reign was marked by factional struggles between the royal in-laws and scholar-officials. A coup attempt by the Yi Ja-gyeom faction was thwarted, but the power struggles weakened the throne and set the stage for later military interventions.

Buddhist monk Myocheong led a rebellion in Seogyeong (Pyongyang), advocating moving the capital there and launching a northern campaign against the Jin dynasty. King Injong initially supported Myocheong but later ordered the rebellion suppressed. The revolt was crushed after a year.

King Injong dispatched General Kim Bu-sik to crush the Myocheong rebellion. The royal forces besieged Seogyeong and defeated the rebels. Myocheong was killed. The victory reaffirmed the capital at Gaegyeong and strengthened the authority of the civil bureaucracy.

Under King Injong's patronage, the scholar-official Kim Bu-sik completed the Samguk Sagi (History of the Three Kingdoms). This is the oldest extant history of Korea, covering the Three Kingdoms period. It was written in Classical Chinese and based on earlier records.
