Will of Fernando Malang Balagtas

The "Will of Fernando Malang Balagtas", sometimes also referred to as the "Will of Pansomun" is a disputed early Spanish-era Philippine document which was supposedly issued either on "25 March 1539" or "25 March 1589" by a "Don Fernando Malang Balagtas", whose original name (before his baptism as a Catholic) was "Pansomun." Despite its provenance having been questioned by Isabelo de los Reyes when he first published a copy of the will in the first volume of his seminal compilation "El Folklore Filipino", and more recently by Philippine scholars such as William Henry Scott, this "Will of Pansomun" is still popularly used as a reference for tracing the genealogies of the kings and lakans who ruled Manila and Tondo until the fall of these dominions to Spanish rule in the 1570s.

It is sometimes dated "25 March 1589" instead of "1539" but this does not reflect the date originally cited by de los Reyes.
