Trần Thánh Tông
Before the conquest of Champa by the Đại Việt emperor Trần Thánh Tông in 1471, the dominant religion of the Cham people was Hinduism, and the culture was heavily influenced by that of India. The Hinduism of Champa was overwhelmingly Shaiva and it was liberally combined with elements of local religious cults such as the worship of the Earth goddess Lady Po Nagar. The main symbols of Cham Shaivism were the lingam, the mukhalinga, the "jaṭāliṅgam", the segmented "liṅgam", and the "kośa".
