Medgar Evers was, like many who came after him, a civil rights leader who was murdered for speaking up. But while he might not be as well known as Martin Luther King Jr. or Malcolm X, he's no less vital to the history of the civil rights movement and is especially noted for his work with the NAACP and tearing down segregation within schools. And his tragic death would expose how deep the corrupted root of racism went in the system, when his killer would not be brought to justice until 30 years later.
