Forces of the Kingdoms of Luzon battled the Empire of Majapahit from Java in what is now Manila. In the mid 14th century, the Majapahit empire mentioned in its manuscript Nagarakretagama Canto 14, written by Prapanca in 1365, that the area of Solot (Sulu) was part of the empire. Nagarakretagama was composed as a eulogy for their emperor Hayam Wuruk. However, Chinese sources then report that in 1369, the Sulus regained independence and in vengeance, assaulted Majapahit and its province, Po-ni (Brunei), looting it of treasure and gold. A fleet from the Majapahit capital succeeded in driving away the Sulus, but Po-ni was left weaker after the attack. The Majapahit Empire, attempted to reconquer the kingdoms of Sulu and Manila but they were permanently repulsed.
