Hayam Wuruk

Hayam Wuruk (1334–1389), regnal name Rajasanagara, was the fourth ruler of Majapahit, under whom the Javanese empire reached its greatest power. Prapanca recorded his birth in the year Mount Kelud erupted, read as a sign that Shiva had taken human form. Raised by his mother Queen Tribhuwana, he came to the throne in 1350 at sixteen, and with Gajah Mada extended Majapahit's sway across the Nusantara archipelago.

In 1357 his planned marriage to Dyah Pitaloka, daughter of the Sundanese king, ended in the Bubat massacre, in which the princess and her party died; court officials blamed Gajah Mada, who had meant to demand Sunda's submission.

In 1365 Prapanca composed the Nagarakretagama in his praise. He sent embassies to China from 1370 to 1381 and died in 1389, after which a succession quarrel between Wikramawardhana and Wirabhumi pulled the empire into decline.
