The Katipunan being a secret organization, its members were subjected to the utmost secrecy and were expected to abide by the rules established by the society. Aspiring applicants were given standard initiation rites in order to become members of the society. At first, membership in the Katipunan was only open to male Filipinos; later, women were accepted into the society. The Katipunan had its own publication, "Kalayaan" (Freedom) which issued its first and last printing in March 1896. Revolutionary ideals and works flourished within the society, and Filipino literature was expanded by some of its prominent members.
