Fernando Primo de Rivera (1831-1921) was a Spanish military officer who served two terms as Captain General of the Philippine Islands (1880-83 and 1897-98). He signed with Emilio Aguinaldo in 1897 the Biak-na-Bato Pact. Dated in August 1898, it is extremely rare and contains a map of Central Luzon. It is a complete and detailed report of his government, from his appointment on March 22, 1897, until his resignation in October of the same year, accepted at the beginning of 1898. Primo de Rivera was accused of incompetence, bad government and improvisation, and the whole writing is a defense of his months of government. Especially juicy is the chapter that narrates the long process of the peace negotiations in which Pedro Paterno played a prominent role. Very important to understand the first phases of the revolution from the political point of view the Governor.
