The Cagayan Revolt, or the First Cagayan Revolt, part of the Revolts Against The Tribute, occurred in 1589 against Spanish colonial rule in Cagayan, the Philippines. It was caused by unjust taxation and alleged abuses by tax collectors of the Spanish colonial government. In response, Governor-General Santiago de Vera sent Spanish and Filipino colonial troops to quell the uprising. Eventually the rebels were pardoned, and the Philippine tax system reformed.[1]
