Cesar Chavez is known as one of America's greatest civil rights leaders. When he led a 340-mile peaceful protest march through California, he ignited a cause and improved the lives of thousands of migrant farmworkers. But Cesar wasn't always a leader. As a boy, he was shy and teased at school. His family slaved in the fields for barely enough money to survive. Cesar knew things had to change, and he thought that--maybe--he could help change them. So he took charge. He spoke up. And an entire country listened.
