Jaya Indravarman IV was the king of Champa, a former region located within modern-day Vietnam, from 1167–1192.
Unsuccessful in purchasing horses from China for an overland invasion, he prepared a squadron of water vessels.
[2]: 120 [3]: 163–164, 166 One of Indravarman IV's inscriptions erected in the Po Nagar temple dated to 1183 recounts how extravagant were the looting gold and silver treasures from the country of Kambu(ja) that were stacked on horse carts, carried to Champa, and were used to donate to the divine Lady Po Nagar by Queen Parameśvari, Queen Rāya, all of the king's Princess Bhägyavatī, Sumitrā, and Sudakṣiṇā, while the rest of the looted Khmer trophy were given to his people throughout the kingdom.
[4] In 1190, the Khmer king Jayavarman VII, the son and successor of Dharanindravarman II, sought vengeance against Champa.
The capital was taken by Vidyanandana and Indravarman was brought back to Cambodia as a prisoner.
