Even, Jose Rizal, considered as the greatest among the Filipino heroes was not explicitly proclaimed as a national hero. The position he now holds in Philippine history is a tribute to the continued veneration or acclamation of the people in recognition of his contribution to the significant social transformations that took place in our country.
Aside, from Rizal, the only other hero, given an implied recognition as a national hero is Andres Bonifacio whose day of birth on November 30 has been made national holiday.
Despite the lack of any official declaration explicitly declaring them as national heroes, they remain admired and revered for their roles in Philippine history. Heroes, according to historians, should not be legislated. Their appreciation should be better left to academics. Acclamation for heroes, they felt. would be recognition enough.
