César Chavez, fought for farm laborers' rights, and worked really hard to improve work conditions for many farm workers.
He was inspired by methods previously used by Mahatma Gandhi, such as strikes, boycotts, fasts and marches, using them to draw attention to his cause. Furthermore, he never answered with full on violence, but he responded with passive resistance, just like Gandhi did.
César Chávez transformed conditions and pay for many labor workers, making him a champion of the poor.
