Katipunan, officially known as the Kataas-taasang, Kagalang-galangang Katipunan ng mga Anak ng Bayan and abbreviated as the KKK, was a revolutionary organization founded in 1892 by a group of Filipino nationalists Deodato Arellano, Andrés Bonifacio, Valentin Diaz, Ladislao Diwa, José Dizon, and Teodoro Plata. Its primary objective was achieving independence from the Spanish Empire through an armed revolution. It was formed as a secret society before its eventual discovery by Spanish authorities in August 1896. This discovery led to the start of the Philippine Revolution.
