Monday, January 18, is a national holiday celebrating the life and achievements of civil rights leader Dr. Martin Luther King Jr., who was assassinated nearly 53 years ago. Dr. King was known for advancing civil rights for African Americans through organizing and leading nonviolent marches. The peaceful marches were unlike the destructive protests we’ve seen recently and drew individuals from all walks of life who respected all people regardless of color, creed, gender, or national origin—values protected by the United States Constitution.
