TODAY IN PHILIPPINE HISTORY:
The “Katastaasang Kagalanggalangang Katipunan ng mga Anak ng Bayan” (KKK) was established in a house on Azcarraga street (now Claro M. Recto), in Tondo Manila in what would be the start of the end of Spanish rule. As a symbol of the member’s loyalty, they performed the solemn rite of sanduguan (blood compact), wherein each one signed his name with his own blood.
The members agreed to recruit more people using the “triangle system” of enlistment. Each original member would recruit new members who were not related to each other. Each new member would do the same thing, and so on down the line.
