The document labelled Declaraciones de Pio Ma. Basa is a relevant primary source concerning the Cavite Mutiny of 1872. It was prepared to clear the name of Pio Ma. Basa, one of those suspected of supporting the “insurección de Cavite." The declaration—in questionand-answer format—establishes the fact that Sr. Pio Ma. Basa is innocent and unfamiliar with the alleged motives of those who participated in the actual mutiny. As a contemporaneous document, it contains the name of those personalities who were implicated including the priests (referred to as presviteros, i.e., presbiteros in the declaracion) Agustin Mendoza, Jose Burgos, and Mariano Gomez and citizens (paysanos, i.e., paisanos in the declaracion) Don Joaquin Pardo (de Tavera), Don Enrique Parayso (i.e., Paraiso), Don Balbino Mauricio, and Don Crisanto de los Reyes. Pio Ma. Basa’s case was pursued by the colonial government. He was deported to Marianas (Guam) for a prison term of six years. (Lars Raymund C. Ubaldo, Ph.D.)
