Tagalog predominance was also a factor that contributed to the failure of Aguinaldo's government. But the aggravating factor was the dictatorial air and brutal conduct of the Tagalog troops, which destroyed the theory of fraternal unity. Ananias Diocno, the Tagalog contingents' leader known for severity in his Capiz and Iloilo campaigns, left a lasting non-commendable remembrance in the history of Panay. American colonial era and advent of Protestantism and counter-reformation (1900–1941) In 1900, no Americans reverted the city's status into a township. By virtue of Act No. 719 of 1903, the municipalities of Jaro, La Paz, Mandurriao, and Molo, were incorporated into the municipality of Iloilo.
