Champa–Đại Việt War (1471)
invasion of the Kingdom of Champa by the Đại Việt

The Cham–Đại Việt War of 1471 or Vietnamese invasion of Champa was a military expedition launched by Emperor Lê Thánh Tông of Đại Việt under the Lê dynasty and is widely regarded as the event that marked the downfall of Champa. In retaliation for Cham raids, Vietnamese forces attacked and sacked the kingdom's largest city-state, Vijaya, and defeated the Cham army, bringing the kingdom of Champa to an end. After this war, the border between Đại Việt and Champa was moved from Hải Vân Pass to Cù Mông Pass from 1471 till 1611 when Nguyễn lords launched another invasion into Phú Yên in the south and annexed it in 1611.
Background
The Cham and the Vietnamese had a long history of conflict. In the course of their wars, peace often coincided with economic exhaustion, with the antagonists rebuilding their economies just to go to war again.
When fighting resumed in 1471, the Champa kingdom found itself weakened and isolated. It had experienced numerous civil wars and, at one point, had five different rulers. Because of the Cham's earlier attack on Angkor, the Khmers ignored their request for assistance when Đại Việt invaded. After an expedition to Champa in 1446, Vietnamese efforts to hold the Cham king as a vassal quickly failed and relations between the two kingdoms deteriorated.
From the mid-15th century onwards, Champa's power steadily waned.
