In 1897, Candido Iban and Francisco Castillo were sent to Aklan to organize the Katipunan in the Visayas. Barrio Lilo-an became the base of the katipunan. And in 1897, believing that the time was ripe for the start of the revolution, eighty-two (82) Katipuneros from Lilo-an marched to the Poblacion to persuade the local authorities to join the revolution. The uprising failed and the leaders captured. Candido Iban, Benito Iban and Gabino Yonsal were among the 19 Martyrs of Aklan executed by the Spanish authorities on March 23, 1897.
