Attila the Hun vs King Jangsu

Attila launched a major invasion of the Eastern Roman Empire, crossing the Danube and sacking cities in the Balkans. The Romans were forced to pay tribute and cede territory. This established Attila as a major threat to Rome.

Attila's Huns fought a coalition of Romans and Visigoths led by Aetius and Theodoric I in Gaul. The battle was indecisive but halted Attila's advance into Gaul. Theodoric was killed. Attila withdrew from Gaul.

Attila invaded Italy, sacking Aquileia and other cities. He forced the Roman emperor Valentinian III to flee Ravenna. The invasion was stopped by a delegation led by Pope Leo I, who negotiated Attila's withdrawal.

Attila died suddenly on his wedding night to a Germanic princess named Ildico. The cause was likely a hemorrhage or alcohol poisoning. His death led to the rapid disintegration of the Hunnic Empire.

Jangsu became king of Goguryeo upon the death of his father, Gwanggaeto the Great. He inherited a vast empire and continued its development.

Jangsu moved the Goguryeo capital from Gungnae (Ji'an) to Pyongyang. This strategic relocation strengthened control over the Korean Peninsula and facilitated trade and diplomacy.

Jangsu sent envoys to the Northern Wei dynasty in China, establishing formal diplomatic relations. This helped secure Goguryeo's borders and facilitated cultural exchange.

Jangsu successfully repelled invasions by the Northern Wei dynasty, maintaining Goguryeo's territorial integrity. His military leadership preserved the kingdom's independence.

Jangsu died at the age of 97, after a reign of approximately 78 years, one of the longest in world history. His rule stabilized and expanded Goguryeo's power.
