The Champa–Đại Việt War marked a significant chapter in the history of the Vietnamese kingdoms, particularly during the reign of Emperor Lê Thánh Tông of Đại Việt. Lê Thánh Tông, who ruled from 1460 to 1497, was known for his progressive reforms and military prowess. His decision to formally attack Chun Kingdom came as a response to long-standing territorial disputes, particularly after previous years of raids and skirmishes between the two nations. The Cham kingdom had seen a decline in power, leading Đại Việt to seek to reclaim lands it deemed rightfully theirs.

The campaign was meticulously planned and executed, reflecting the military innovations and strategies developed by Lê Thánh Tông’s commanders. Troops were mobilized from various provinces, and the emperor placed a great emphasis on logistics and supply lines to ensure a sustained offensive. The Đại Việt forces faced the Cham armies, which had suffered from internal strife and were less organized than in previous decades, contributing to their vulnerabilities during the conflict.

Lê Thánh Tông's military campaign against Champa not only aimed at overcoming the Cham resistance but also at solidifying his reign domestically by showcasing military success. The swift victories that followed opened the way for further expansion into Champa territory, leading to the eventual capture of key cities. This expansion not only increased territorial control but also enhanced the economic prospects of Đại Việt by expanding trade routes and resources.
