During the Spanish colonization of the Philippines, a secret society of "insurrectos" was organized in the municipality. Its purpose was to fight and revolt against the Spanish Government in the area. On the eve of the revolution, a traitor told the Spanish of their plan. The Spanish soldiers, without any investigation, arrested seven members of the secret society and executed them the same night. Only one, Fernando Ostrea, escaped with leg wounds. He informed the people about what has happened. In memory of the seven Martyrs, a masonic lodge, Siete Martires Lodge No. 177, was organized.
