The Cry of Pugad Lawin (Tagalog: Sigaw ng Pugad Lawin, Spanish: Grito de Pugad Lawin) was the beginning of the Philippine Revolution against the Spanish Empire. In late August 1896, members of the Katipunan led by Andrés Bonifacio revolted somewhere around Caloocan, which included parts of the present-day Quezon City. Because accounts of the event vary, the exact date and place of the event is unknown. From 1908 until 1963, the event was thought to have occurred on August 26 in Balintawak. In 1963, the Philippine government declared August 23 to be the date of the event in Quezon City.
