Ache (c. 1500s - 1572; Old Spanish orthography: Rája Aché or Raxa Ache, also known as Ráha Matandâ, was Rajah of Maynila, now the site of the capital of the Republic of the Philippines, Manila. The pre-colonial wider Maynila region connected by Manila Bay was also known as Lusong, from which the much larger colonial and modern region of Luzon was later named after. A younger Ache thus appears as the "Prince of Luzon" in historical testimonies predating the Spanish conquest of Maynila in his old age when he was the Rajah Matanda, but "Luzon" in this context should be understood to mean Lusong, i.e. only Maynila and the wider Manila Bay area at most instead of the whole of modern-day Luzon.
