Eannatum vs King Jangsu of Goguryeo

Eannatum defeated the forces of Umma in a battle near the boundary canal between Lagash and Umma. The victory was commemorated on the Stele of the Vultures, which shows vultures carrying away the heads of the defeated. This established Lagash's dominance over Umma.

Eannatum, king of Lagash, commissioned the Stele of the Vultures, the first known historical document. The stele depicts his victory over Umma and records the boundary treaty between the two city-states. It is a key source for early Sumerian warfare and diplomacy.

Eannatum campaigned against Elam and Subartu, extending Lagash's influence beyond Sumer. Inscriptions record his victories and the tribute he exacted from these regions. This expansion made Lagash a major power in Mesopotamia during his reign.

King Jangsu moved the Goguryeo capital from Gungnae to Pyongyang, constructing a new fortress city. This relocation strengthened control over the southern territories and facilitated expansion into the Korean peninsula.

King Jangsu led a military campaign that captured the Han River basin from the Baekje kingdom, including the capital Hanseong. This victory gave Goguryeo control over a strategic waterway and rich agricultural lands, significantly expanding its territory.

King Jangsu established diplomatic relations with the Northern Wei dynasty of China, exchanging envoys and tribute. This alliance balanced against the Southern Dynasties and secured Goguryeo's northern borders.

King Jangsu forced the Silla kingdom to become a vassal state of Goguryeo after a series of military campaigns. Silla paid tribute and accepted Goguryeo's suzerainty, establishing Goguryeo as the dominant power in the Korean peninsula.

King Jangsu died after a reign of 79 years, the longest of any Korean monarch. His rule saw Goguryeo reach its maximum territorial extent and peak power, controlling much of Manchuria and the Korean peninsula.
