The Spanish–Moro conflict (Filipino: Sagupaang Kastila at Moro) was a series of battles in the Philippines lasting over several centuries. It began during the Spanish Era and lasted until the Spanish–American War, when Spain finally began to subjugate the Moro people after centuries of poor attempts to do so. Spain ultimately conquered portions of the Mindanao and Jolo islands and turned the Sultanate of Sulu into a protectorate, establishing geographic dominance over the region until the Spanish-American War. Moro resistance continued.
