Kertanegara

Kertanegara, also called Sivabuddha (died 1292), was the last king of Singhasari, ruling East Java from 1268; his father Wisnuwardhana had enthroned him in 1254. He was the first Javanese ruler to expand beyond Java: Bali submitted in 1284, and Madura and parts of Borneo acknowledged him.

When Kublai Khan's envoys demanded tribute in 1289, he had them branded, mutilated and expelled. In 1290 he sent his army to Sumatra, and in 1292, with it abroad, the rebel Jayakatwang stormed the palace and killed him, clearing the way for Raden Wijaya's Majapahit.
