In battles in the Philippines and Puerto Rico during the Spanish-American War, American forces were joined by local insurgents and Filipino nationalists in the Philippines, who sought independence from Spanish rule. In Puerto Rico, American troops faced little resistance as the local population largely welcomed them, viewing the arrival of U.S. forces as a liberation from Spanish colonial rule. These collaborations played a significant role in the swift American victories in both territories.
