## Who they were

Ly Thuong Kiet (1019-1105) was the great general-statesman of the Ly dynasty: a court eunuch who rose to supreme command of the army. He served three emperors and died in 1105 at 86.

## What they did

Facing an impending Song invasion, he struck first in 1075-76, taking the border prefectures including Yongzhou, then withdrew. When the Song counter-offensive came, he met it at the Nhu Nguyet (Cau) River line in 1077; the invasion stalled there and was negotiated to an end. The four-line poem "Nam quoc son ha" - "The Southern country's mountains and rivers are the Southern emperor's dwelling" - is traditionally said to have been proclaimed to hearten his troops on that river; scholarship treats its authorship as anonymous, and its framing as a "first declaration of independence" is a later tradition. He also led campaigns against Champa.

## Legacy

He remains the model of active defense in Vietnamese military history. Streets across Vietnam bear his name.
