Martin Luther King Jr. (born Michael King Jr.; January 15, 1929 – April 4, 1968) was an American Baptist minister and activist 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 nonviolence and civil disobedience. Inspired by his Christian beliefs and the nonviolent activism of Mahatma Gandhi, he led targeted, nonviolent resistance against Jim Crow laws and other forms of discrimination in the United States.
