In the 16th century, Rajah Matanda, also known as Ache, was the ruler of Tondo which now encompasses the present areas of Bulacan, Metro Manila, Rizal and Quezon. He was the heir to his father's throne and his maternal grandfather, Siripada I (or Bolkeiah I), was the sultan of Borneo. In 1521, he went to Borneo to marry a cousin, however, along his voyage back to Manila, he was caught by the survivors of Ferdinand Magellan's expedition but Ache payed ransom. The fact that Borneo was providing a princess for the Chief of Manila indicates that at this period, Manila has a certain degree of power or status.
