1896 - The Philippine revolutionary movement is prematurely  discovered by the Spaniards when the hated Fr. Mariano Gil, the  curate of Tondo who has heard about it through a confession from a Filipino traitor,  breaks his vow of silence and reports about its existence and headquarters to the colonial authorities; in response to the  mounting cruelty inflicted by the Spaniards on  members of Kataastaasang, Kagalanggalangang Katipunan nang  manga Anak nang Bayan (KKK) who have been arbitrarily arrested  and imprisoned, Supremo Andres Bonifacio instructs messengers  to summon his leaders to a general assembly to discuss measures  to counter the development; later, a Katipunan poster threatening the killing of Fr. Gil would appear on the poster of the Tondo church.

1939 -  On his 61st birthday, Manuel L. Quezon, President of the  American-sponsored Commonwealth government of the  Philippines, issues Executive Order No. 217 that prescribes a  16-point code of ethics to be taught in all schools in the  Southeast Asian archipelago.
