One of the four small states, named after regions of India - Amaravati (Quang Nam); Vijaya (Binh Dinh); Kauthara (Nha Trang); and Panduranga (Phan Rang) - of Champa (now southern Vietnam). Champa was formed in 192 AD during the breakup of the Han dynasty in China. The states' populations remained concentrated in small coastal enclaves. To this period belong several brick sanctuaries in the Nha-trang area, notably that of Po Nagar. Nha-trang dates to the 3rd century AD, when, as part of the independent land of Kauthara, it acknowledged the suzerainty of Funan.
