Martin Luther King Jr. was a scholar and minister who led the civil rights movement. After his assassination, he was memorialized by Martin Luther King Jr. Day.

Who Was Martin Luther King Jr? Martin Luther King Jr. was a Baptist minister and civil-rights activist who had a seismic impact on race relations in the United States, beginning in the mid-1950s. Among his many efforts, King headed the Southern Christian Leadership Conference (SCLC). Through his activism and inspirational speeches, he played a pivotal role in ending the legal segregation of African-American citizens in the United States, as well as the creation of the Civil Rights Act of 1964 and the Voting Rights Act of 1965. King won the Nobel Peace Prize in 1964, among several other honors. He continues to be remembered as one of the most influential and inspirational African-American leaders in history.

Early Life Born as Michael King Jr. on January 15, 1929, Martin Luther King Jr. was the middle child of Michael King Sr. and Alberta Williams King. The King and Williams families had roots in rural Georgia. Martin Jr.'s grandfather, A.D. Williams, was a rural minister for years and then moved to Atlanta in 1893. He took over the small, struggling Ebenezer Baptist church with around 13 members and made it into a forceful congregation. He married Jennie Celeste Parks and they had one child that survived, Alberta. Martin Sr. came from a family of sharecroppers in a poor farming community. He married Alberta in 1926 after an eight-year courtship. The newlyweds moved to A.D.'s home in Atlanta. Martin Sr. stepped in as pastor of Ebenezer Baptist Church upon the death of his father-in-law in 1931. He too became a successful minister and adopted the name Martin Luther King Sr. in honor of the German Protestant religious leader Martin Luther. In due time, Michael Jr. would follow his father's lead and adopt the name himself.

The King children grew up in a secure and loving environment. Martin Sr. was more the disciplinarian, while his wife's gentleness easily balanced out the father's strict hand. Though they undoubtedly tried, King’s parents couldn’t shield him completely from racism. Martin Sr. fought against racial prejudice, not just because his race suffered, but because he considered racism and segregation to be an affront to God's will. He strongly discouraged any sense of class superiority in his children which left a lasting impression on Martin Jr. Growing up in Atlanta, Georgia, King entered public school at age five. In May 1936 he was baptized, but the event made little impression on him. In May 1941, King was 12 years old when his grandmother, Jennie, died of a heart attack. The event was traumatic for King, more so because he was out watching a parade against his parents' wishes when she died. Distraught at the news, young King jumped from a second-story window at the family home, allegedly attempting suicide. King attended Booker T. Washington High School, where he was said to be a precocious student. He skipped both the ninth and eleventh grades, and entered Morehouse College in Atlanta at age 15, in 1944. He was a popular student, especially with his female classmates, but an unmotivated student who floated through his first two years. Although his family was deeply involved in the church and worship, King questioned religion in general and felt uncomfortable with overly emotional displays of religious worship. This discomfort continued through much of his adolescence, initially leading him to decide against entering the ministry, much to his father's dismay. But in his junior year, King took a Bible class, renewed his faith and began to envision a career in the ministry. In the fall of his senior year, he told his father of his decision.

Education and Spiritual Growth In 1948, King earned a sociology degree from Morehouse College and attended the liberal Crozer Theological Seminary in Chester, Pennsylvania. He thrived in all his studies, and was valedictorian of his class in 1951, and elected student body president. He also earned a fellowship for graduate study. But King also rebelled against his father’s more conservative influence by drinking beer and playing pool while at college. He became involved with a white woman and went through a difficult time before he could break off the affair. During his last year in seminary, King came under the guidance of Morehouse College President Benjamin E. Mays who influenced King’s spiritual development. Mays was an outspoken advocate for racial equality and encouraged King to view Christianity as a potential force for social change. After being accepted at several colleges for his doctoral study, King enrolled at Boston University. During the work on his doctorate, King met Coretta Scott, an aspiring singer and musician at the New England Conservatory school in Boston. They were married in June 1953 and had four children, Yolanda, Martin Luther King III, Dexter Scott and Bernice. In 1954, while still working on his dissertation, King became pastor of the Dexter Avenue Baptist Church of Montgomery, Alabama. He completed his Ph.D. and earned his degree in 1955. King was only 25 years old. Montgomery Bus Boycott On March 2, 1955, a 15-year-old girl refused to give up her seat to a white man on a Montgomery city bus in violation of local law. Teenager Claudette Colvin was then arrested and taken to jail. At first, the local chapter of the NAACP felt they had an excellent test case to challenge Montgomery's segregated bus policy. But then it was revealed that Colvin was pregnant and civil rights leaders feared this would scandalize the deeply religious Black community and make Colvin (and, thus the group's efforts) less credible in the eyes of sympathetic white people. On December 1, 1955, they got another chance to make their case. That evening, 42-year-old Rosa Parks boarded the Cleveland Avenue bus to go home after an exhausting day at work. She sat in the first row of the "colored" section in the middle of the bus. As the bus traveled its route, all the seats in the white section filled up, then several more white passengers boarded the bus. The bus driver noted that there were several white men standing and demanded that Parks and several other African Americans give up their seats. Three other African American passengers reluctantly gave up their places, but Parks remained seated. The driver asked her again to give up her seat and again she refused. Parks was arrested and booked for violating the Montgomery City Code. At her trial a week later, in a 30-minute hearing, Parks was found guilty and fined $10 and assessed $4 court fee. On the night that Parks was arrested, E.D. Nixon, head of the local NAACP chapter met with King and other local civil rights leaders to plan a Montgomery Bus Boycott. King was elected to lead the boycott because he was young, well-trained with solid family connections and had professional standing. But he was also new to the community and had few enemies, so it was felt he would have strong credibility with the Black community. In his first speech as the group's president, King declared, "We have no alternative but to protest. For many years we have shown an amazing patience. We have sometimes given our white brothers the feeling that we liked the way we were being treated. But we come here tonight to be saved from that patience that makes us patient with anything less than freedom and justice."
