The Filipino Heroism. History. Current Events.

Son of Santiago Bonifacio and Catalina de Castro. Andrés Bonifacio, a self-educated man of the urban working class, organized a secret society called Katipunan, short for Kataastaasan Kagalang-galang na Katipunan ng mga Anak ng Bayan (The Highest and Most Respectable Society of the Sons of the People).

The Katipunan, which advocated revolution rather than reform, gained a popular base of support, with membership concentrated among urban and rural workers. Spanish officials discovered, through an informant parish priest, the existence of the Katipunan in August 1896. Bonifacio, realizing the Katipunan could no longer hide its activity, proclaimed the beginning of the revolution. Katipunan members first attacked Spanish military installations, and then the insurrection spread throughout the provinces of central Luzon.
