Note 1 — Letter from the Viceroy of New Spain to Felipe II
Reading edition
The term Moros (“Moors”) was applied by the Spaniards and Portuguese to these Malayans, simply because they were, at least nominally, Mahometans. Their residence was mainly in the islands of Mindanao, Jolo, Paragua, and Balábac. Most of them were pirates, who for centuries harassed not only the Spanish settlements, but those of the Filipinos.
