Lourdes Rausa-Gomez. "Sri Yijava and Madjapahit"(PDF). "Lourdes Rausa-Gomez cited Sir Stamford Raffles, himself citing the "Traditional History of Java" wherein he said that Manila and Sulu in the Philippines were part of Majapahit, however she doubted the veracity of Stamford Raffles assertion due to the lack of archaeological evidence between Majapahit and the Philippines in her 1967 article. However, that article has been renderred outdated due to the discovery of the Laguna Copperplate Inscription in 1989 which proved links between Java and Manila, which makes her dismissal of the Raffles assertion null and the Raffles assertion feasible."
