The first Filipino flag can be traced from the time of the Andres Bonifacio's secret society named: Kataastaasang Kagalanggalang Katipunan ng mga Anak ng Bayan (Highest and Most Honorable Society of the Sons of the Nation) or the Katipunan or KKK for short. Benita Rodriquez and Bonifacio's wife, Gregoria de Jesus.
It was in this skirmish that the Philippine flag was first unfurled as the revolutionary standard. Sewn in Hong Kong by Filipino expatriates and brought to the country by Aguinaldo, the flag was a tri-color featuring red and blue with a white triangle framing three yellow stars and an anthropomorphic eight-rayed sun.
The eight rays of the sun represent the provinces of Manila, Bulacan, Pampanga, Nueva Ecija, Morong, Laguna, Batangas and Cavite, which were declared under Martial Law by a Decree of the Spanish government during the revolution of 1896.
