Flags of The Philippine Revolution - Katipunan Flags

With the establishment of the Katipunan, Andrés Bonifacio requested his wife, Gregoria de Jesús, to create a flag for the society. De Jesús devised a simple red flag bearing the society's acronym, KKK, in white and arranged horizontally at the center. This became the society's first flag.

Some Katipunan members used other variations. One variation has the three Ks arranged in the form of a triangle. Some others used a red flag with only one K.

When the revolution heated up, the Magdiwang faction of the Katipunan, which operated in Cavite under Mariano Álvarez, adopted a flag consisting of a red banner with a white sun with the baybayin (the ancient Tagalog script) letter ka (for K) at the center.

The Magdalo faction of the Katipunan, which also operated in Cavite under Emilio Aguinaldo, used a flag similar to the Magdiwang faction's, featuring a white sun with a baybayin letter ka. The sun initially had an indefinite number of rays and was later standardized to eight rays, to represent the eight provinces that Spanish colonial authorities placed under martial law (Manila, Cavite, Laguna, Batangas, Bulacan, Pampanga, Bataan, and Nueva Ecija). An eight-rayed sun was later used in the national flag of the Philippines.
