Teodoro Agoncillo

Teodoro Andal Agoncillo was a Filipino historian from the 20th century. He and his contemporary, Renato Constantino, were among the first Filipino historians renowned for promoting a Filipino nationalist historiography. Agoncillo was a professor at the University of the Philippines (UP) and chaired the UP Department of History from 1963 to 1969. His seminal work, The Revolt of the Masses: The Story of Bonifacio and the Katipunan (1956), recounts the early phase of Philippine Revolution led by Andrés Bonifacio's Katipunan. He also authored History of the Filipino People, a standard textbook first published in 1960. In 1985, Agoncillo was posthumously named a National Scientist of the Philippines.
