The Eleventh Cham-Quenminese War, also called the Eleventh Cham-Đại Quến War, the Second Cham-Lận War and the Pacification of Chamdat, was the final major conflict between a Quenminese dynasty and the independent kingdom of Chamdat. In a last attempt for the latter realm become independent due to the unfair economic policies and tributary taxes that were imposed by Emperor Xương Thắng, the penultimate king, Lomaharsana VII, commenced holy war throughout the Dynasty's southern territories. The Emperor then issued an edict calling for the pacification of the kingdom and bestowed his Grand Chancellor Nguyễn Ngọc Quyết the power and means to oversee the conflict's tide to the Dynasty's favor. After over three years, the Dynasty achieved a decisive victory, which necessitated them to depose the last king Apratimaujas IX and integrate Chamdat into another province.

The conflict saw a combination in the use of traditional weapons and the growing prominence of western weapons and material, such as the musket. Both sides were inclined to adapt and utilize them in order to compete for superior firepower to consummate their goals. Furthermore, the purchase of ships from [insert Western-themed empire here] helped to augment the naval forces of the belligerents, further intensifying the need of superior force.

In the aftermath of the war, the Dynasty imposed a significant and repressive Quenicization policy among the Cham populace. Justifying this resolve as a punishment for extreme insubordination, the Dynasty often enacted measures of coercion and brutality against the Chams, especially ones that targeted their cultural values and traditions. This would eventually lead to a final and quelled attempt by the Chams to reestablish their independence in the Rebellion of Chhet Sorya. Eventually, the Chams were fully assimilated, although some of their traditions have been revitalized to this day. This war was considered by Quenminese and Cham historians to have been the fateful indication of Chamdat's inability to obtain and preserve its independence.
