The Vietnamese Ly dynasty conquered the Cham and Khmer people.

The first century of the reign of the emperors Lý was marked by the wars with China and the two Indianized kingdoms of the south: Champa and Chenla.

Under the direction of the Ly, their military expansion to the south began, in detriment of the kingdoms of the Cham and Khmers. In 982 Emperor Lê Đại Hành of the earlier dynasty had already plundered the Cham capital, Indrapura, causing them to establish a new capital in Vijaya. The Ly emperors conquered Vijaya, and in 1079 the three septentrional provinces of the kingdom were annexed. The new territories were occupied progressively by Vietnamese peasants who were turning all virgin coast lands into rice fields.
