in its manuscript Nagarakretagama Canto 14, written by Prapanca in 1365, that the area of Saludung (Selurong) and Solot (Sulu) were parts of the empire. Nagarakretagama was composed as a eulogy for their emperor Hayam Wuruk. Chinese source mentioned that in 1369, the pirates of Sulu attacked Po-ni (Brunei), looting it of treasure and gold. A fleet from Majapahit succeeded in driving away the Sulus, but Po-ni was left weaker after the attack. Establishment by Sultan Bolkiah and the Sultanate of Brunei ( 1500) According to Bruneian oral tradition, a city with the Malay name of Selurong, which would later become the city of Maynila) was formed around the year 1500. This oral tradition claims that Sultan Bolkiah (1485–1521) of the Sultanate of Brunei attacked Tondo and established the polity of Seludong (Maynila) as a satellite state of the Sultanate of Brunei. This is narrated through Tausug and Malay royal histories, where the names Seludong, Saludong or Selurong are used to denote Manila prior to colonisation.

Territorial conflicts with Tondo (before 1521) According to the account of Rajah Matanda as recalled by Magellan expedition members Gines de Mafra, Rodrigo de Aganduru Moriz, and expedition scribe Antonio Pigafetta, Rajah Matanda's father (whose name was not mentioned in the accounts) died when he was still very young. Rajah Matanda's mother (also unnamed in the Spanish accounts) then became the paramount ruler of the Maynila polity. In the meantime, Rajah Matanda, then simply known as the "Young Prince" Ache, was raised alongside his cousin, who was ruler of Tondo - presumed by some to be a young Bunao Lakandula, although not specifically named in the Spanish
