This document summarizes the Spanish-Moro wars between Spain and the Sultanates in the Philippines over a period of 35 years. It describes the initial raids by the Moro sultanates on Spanish settlements in the Visayas in the late 1500s. This led to retaliatory attacks by Spain and periods of tense peace. Major events included the 1635 Spanish building of a fort in Zamboanga, and warfare led by the Sultan Kudarat in the 1630s-1640s contesting Spanish expansion.
