What role did the Katipunan play in the Philippine Revolution?

The Katipunan was a pivotal Filipino nationalist organization founded in 1892 by Andrés Bonifacio and other activists following the arrest of José Rizal. Dedicated to the expulsion of Spanish colonial rule, the society transformed the nature of Filipino resistance by grounding it in nationalist ambitions and organized preparation for armed revolt.123

The organization’s role in the Philippine Revolution included:

• Mobilization: It grew to an estimated 100,000 to 400,000 members, primarily Tagalogs, creating a broad base for the independence movement.42
• Initiating Conflict: In August 1896, after Spanish authorities discovered their plans, the Katipunan was forced into premature action, sparking revolts in provinces surrounding Manila.52
• Leadership Transition: While Bonifacio initially led the society, leadership of the revolutionary forces eventually shifted to Emilio Aguinaldo in 1897.42

By providing the first coordinated, nationalist-driven structure for rebellion, the Katipunan made the eventual end of Spanish colonial administration a reality.2
