Amavarati

Amaravati was a Cham polity in the Thu Bồn river basin, with religious centres among the mountains and a trading coast around Hội An. Its rulers endowed the sacred valley of Mỹ Sơn with temples to Shiva, while the monastery of Đồng Dương bore witness to the importance of Mahayana Buddhism. Inscriptions and brick towers marked a region linked by river to the sea and to merchants from distant ports.

The region became a frontier between Champa and Đại Việt. In 1402 the Hồ rulers of Đại Việt took the territories of Chiêm Động and Cổ Lũy, south of the Thu Bồn. Control remained contested in the following decades. After the Vietnamese conquest of Vijaya in 1471, King Lê Thánh Tông established Quảng Nam over these lands. The old Cham monuments endured as reminders of the religious and artistic world that had flourished along the river.

The later city of Quảng Ngãi lies here.
