This year we remember the 43rd anniversary of the declaration of Martial Law. The Presidential Communications Development and Strategic Planning Office (PCDSPO) has published a series of special pages; the pages will feature a briefer, and a comprehensive timeline of the important events before and after the declaration of martial law, among other resources.

These resources emphasize that September 23, 1972, was the date Martial Law was declared and implemented, contrary to the popular notion that it was on September 21. Specifically, the briefer and the timeline on Martial Law present the contrasting views of historians as to the actual date, and highlight the fact that the moment Martial Law was put into full effect was after the nationwide address of Ferdinand Marcos on September 23, 1972.

The photo collection was collected from contributions by the National Library of the Philippines, the Presidential Museum and Library, the First Quarter Storm Library, the Quezon Family Collection, the Manila Bulletin, the Philippine Diary Project, the Manila Times, the Gerry Roxas Foundation, the Philippine Collegian, the Philippines Free Press, Jose W. Diokno Foundation, Willie Vicoy, and Vic Torres.
