Martin Luther King Jr. was an American Christian minister, activist, and political philosopher who was one of the most prominent leaders in the civil rights movement from 1955 until his assassination in 1968. A black church leader and a son of early civil rights activist and minister Martin Luther King Sr., King advanced civil rights for people of color in the United States through the use of nonviolent resistance and nonviolent civil disobedience against Jim Crow laws and other forms of legalized discrimination.

Civil disobedience is the active, professed refusal of a citizen to obey certain laws, demands, orders or commands of a government. By some definitions, civil disobedience has to be nonviolent to be called "civil". Hence, civil disobedience is sometimes equated with peaceful protests or nonviolent resistance.
