Vijaya (Sanskrit for "victorious"[a]), also known as Vijayapura, was the capital of the Kingdom of Champa located in modern-day Bình Định province, Vietnam.

It served as the capital of the Kingdom of Champa from the 12th century CE until it was conquered by Đại Việt during the Champa–Dai Viet War of 1471.

[3] Records suggest that there was an attack on Vijaya's citadel from the Vietnamese in 1069 (when Dai Viet was ruled by Lý Nhân Tông) to punish Champa for armed raiding in Vietnam.

[7] Michael Vickery insists that the 1069 Vietnamese raid did not target Vijaya, but probably Châu Sa & Cổ Lũy citadels on the north and south banks of the Trà Khúc River in Quảng Ngãi province.

Châu Sa was a large port city named Amaravati, has the temple of Chánh Lộ dating to eleventh century.

[14] Major wars with Vietnam were fought again in the 15th century, which eventually led to the defeat of Vijaya and the demise of Champa in 1471.

[18] Vijaya was centred on the lowland area along lower Côn River, in what is now the south of Bình Định Province.

[19] According to two noteworthy 15th century reports noted in the Vietnamese grand chronicles, Toàn thư, Vijaya had a small number of households, just 2,500, or approximately 10,000 inhabitants.

[21] It also points to the relative abundance of labour in Vijaya compared to other Champa centres of powers, because processing stones for construction was more labour-intensive than the production of bricks.
