Lewis often paired this phrase with "necessary trouble" to describe peaceful protests that actively disrupted unjust systems of segregation.

At just 23 years old, Lewis represented the Student Nonviolent Coordinating Committee and was asked to tone down his originally radical speech.

Lewis chose this illustrated format because a 1957 comic book about Martin Luther King Jr. had deeply inspired his own early activism.

The brutal police attacks on the marchers became known as "Bloody Sunday" and directly spurred the passage of the Voting Rights Act of 1965.
