A long-time academician and administrator from the University of the Philippines, Gabriel F. Fabella (1898-1982) was a rare Filipino intellectual who was both a history-maker and kingmaker of his time. Gifted with intellect and driven by strong determination to succeed, he was a self-made man from Romblon who rose from abject poverty. As a neophyte lawyer, he defeated a veteran politician and was elected assemblyman of his province in 1935 under the auspices of the Philippine Commonwealth. After World War II, he effectively utilized his political background and wide network to promote nationalism and civic virtues. Through his writings, speeches, and radio interviews, he helped shape the government’s position in shifting the Philippine Independence Day from July 4 to June 12 in 1962.

This paper seeks to discuss Fabella’s numerous contributions as an influential Filipino historian beyond his title as the “Father of June 12.” It argues that he was largely instrumental in the early survival and success of Philippine Historical Association (PHA), a leading national organization of Filipino professional historians, from its founding in 1955 until the next two decades of its existence. This was a crucial period in Philippine History as the Third Philippine Republic navigated nation-building and decolonization at the height of the Cold War. As it approaches its 75th founding anniversary, it is but fitting and proper for PHA to continually recognize the life and many legacies of its founding president and president emeritus.
