The individual known for advocating nonviolent protest during the Civil Rights Movement was Martin Luther King Jr.

Inspired by Mahatma Gandhi's philosophy of nonviolence, King emphasized peaceful resistance as a means to achieve racial equality and social justice. He believed that love and understanding could overcome hatred and oppression. King led numerous peaceful demonstrations, including the Montgomery Bus Boycott and the March on Washington, where he delivered his iconic "I Have a Dream" speech. His approach played a crucial role in advancing civil rights and influencing legislation, such as the Civil Rights Act of 1964.
