The National Historical Commission of the Philippines joins the people of Imus City, Cavite in remembering the 150th birth anniversary of Santiago Alvarez on 25 July 2022.

Born in Imus City, Cavite on 25 July 1872, Alvarez was the only child of General Mariano Alvarez and Nicolasa Virata. While studying to become a teacher, he joined the Katipunan under the nom-de-guerre Kidlat ng Apoy and recruited many of his fellow CaviteƱos, including Emilio Aguinaldo.

When the Revolution erupted in August 1896, he joined his father and his cousin, Pascual Alvarez, in liberating the town of Noveleta. He also led Filipino forces into a decisive victory at the Battle of Dalahican, a battle which lasted from 9 November to 11 November 1896. In recognition of his leadership in battle, he was appointed Lieutenant General on 27 December 1896.

After the Americans firmly established control over the Philippines, Alvarez helped build the Nacionalista Party in 1901. (This was different from the still-existing Nacionalist Party founded in 1907). He also became active in the Iglesia Filipina Independiente and Makabuhay Association. He died in San Pablo City, Laguna on 30 October 1930 at the age of 58.

Today, Alvarez is also known for providing historians with details about the early stages of the Philippine Revolution. His memoir, Ang Katipunan at ang Paghihimagsik, was serialized in the newspaper Sampagita from 24 July 1927 to 15 April 1928. This was later compiled, translated in English by Paula Carolina Malay, and published by the Ateneo de Manila University Press in 1992.

The NHCP is the national government agency mandated to promote Philippine history through its museums, research and publications, and to preserve historical heritage through conservation and the marking of historic sites and structures.
