Rizal became the Philippine national hero because he fought for freedom through his writings rather than violence or aggression. The Rizal Act of 1956 requires schools to teach about Rizal's life and works, particularly his novels Noli Me Tangere and El Filibusterismo. A hero is defined as an illustrious person who sacrifices themselves through courageous actions or principles, taking charge to lead people to victory or losing their life for their beliefs.
