Considered as a radical historian, Prof. Agoncillo had been a major influence in Philippine historiography, which reflects the Filipino point of view, from the beginnings when it was largely unpopular, to the present when it is now integral with Filipino writing of history. He authored about 20 books and numerous articles on history. Among his books are: Ang Kasaysayan ng Pilipinas; The revolt of the masses: The story of Bonifacio and the Katipunan; Malolos. The Crisis of the Republic; Philippine History (adopted as the official textbook in Philippine History); and the History of the Filipino People.
For his contributions to literature and Philippine historical writing, the community of scholars, as well as private and public institutions, had given him the title University Professor, the highest academic appointment in any university.
