Jayavarman VIII (), posthumous name Paramesvarapada, was one of the prominent kings of the Khmer empire. His rule lasted from 1243 until 1295, when he abdicated. One of his wives was Queen Chakravartirajadevi. In 1283, he decided to pay tribute and buy peace and thus his rule survived. Chinese annals record that in 1291, "the king of Zhenla / 真臘" [Cambodia] sent a mission who presented "the usual tribute of gold, elephant ivory and other things". In 1290, the Mon people of Lavo kingdom abolished its status as a tributary state of the Khmer Empire because it felt the Khmer king was too weak to deal with the Mangol.
Jayavarman VIII suffered a devastating war against the Xiān.
