Andres Bonifacio was a Filipino nationalist and revolutionary who founded the secret society Katipunan in 1892 which sought independence from Spanish colonial rule. He served as the supreme leader of the Katipunan and is considered a de facto national hero of the Philippines. Emilio Jacinto, known as the "Brains of the Katipunan", joined the secret society at a young age and served as Bonifacio's adviser, writing many of the Katipunan's principles and documents under various pseudonyms. Both men played pivotal roles in the Katipunan and Philippine Revolution before ultimately dying in the late 1890s.
