On August 28, 1963, Dr. Martin Luther King Jr. changed the social landscape of the United States with his iconic “I Have a Dream” speech. In the wake of his achievements, we see modern champions of freedom taking their cues from Dr. King, organizing everything from peaceful marches for gender equality to forming organizations that fight daily for our freedoms. Today, on Dr. King’s namesake holiday, we remember the sacrifice and the struggle of the movement this man led and continue his legacy of peaceful change. Let these nine monuments serve as a reminder that any individual can effect change for the betterment of others.
