Martin Luther King, Jr. (January 15, 1929 – April 4, 1968) was a famous leader of the American civil rights movement, a political activist, and a Baptist minister. In 1964, King became the youngest man to be awarded the Nobel Peace Prize (for his work as a peacemaker, promoting nonviolence and equal treatment for different races). On April 4, 1968, Dr. King was assassinated in Memphis, Tennessee. In 1977, he was posthumously awarded the Presidential Medal of Freedom by Jimmy Carter. In 1986, Martin Luther King Day was established as a United States holiday. In 2004, King was posthumously awarded the Congressional Gold Medal. He was known as a great public speaker. Dr. King often called for personal responsibility in fostering world peace. King's most influential and well-known public address is the "I Have A Dream" speech, delivered on the steps of the Lincoln Memorial in Washington, D.C.

Martin Luther King, Jr. was born on January 15, 1929, in Atlanta, Georgia. He was the son of the Reverend Martin Luther King, Sr. and Alberta Williams King. According to his father, the attending physician mistakenly entered "Michael" on Martin Jr.'s birth certificate. King entered Morehouse College at the age of fifteen, as he skipped his ninth and twelfth high school grades without formally graduating. In 1948, he graduated from Morehouse with a Bachelor of Arts (B.A.) degree in sociology, and enrolled in Crozer Theological Seminary in Chester, Pennsylvania and graduated with a Bachelor of Divinity (B.D.) degree in 1951. In September of that year, King began doctoral studies in Systematic Theology at Boston University and received his Doctor of Philosophy (Ph. D.) on June 5, 1955.

In 1953, at the age of twenty-four, King became pastor of the Dexter Avenue Baptist Church, in Montgomery, Alabama. On December 1, 1955, Rosa Parks was arrested for refusing to comply with the Jim Crow laws that required her to give up her seat to a white man. The Montgomery Bus Boycott, led by King, soon followed. (In March of the same year, a 15 year old school girl, Claudette Colvin, suffered the same fate but King refused to become involved, instead preferring to focus on leading his church.) The boycott lasted for 382 days, the situation becoming so tense that King's house was bombed. King was arrested during this campaign, which ended with a United States Supreme Court decision outlawing racial segregation on all public transport.

King was instrumental in the founding of the Southern Christian Leadership Conference (SCLC) in 1957, a group created to harness the moral authority and organizing power of black churches to conduct non-violent protests in the service of civil rights reform. King continued to dominate the organization. King was an adherent of the philosophies of nonviolent civil disobedience used successfully in India by Mahatma Gandhi, and he applied this philosophy to the protests organized by the SCLC.

The FBI began wiretapping King in 1961, fearing that Communists were trying to infiltrate the Civil Rights Movement, but when no such evidence emerged, the bureau used the incidental details caught on tape over six years in attempts to force King out of the preeminent leadership position.

King correctly recognized that organized, nonviolent protest against system of southern segregation known as Jim Crow laws would lead to extensive media coverage of the struggle for black equality and voting rights. Journalistic accounts and televised footage of the daily deprivation and indignities suffered by southern blacks, and of segregationist violence and harassment of civil rights workers and marchers, produced a wave of sympathetic public opinion that made the Civil Rights Movement the single most important issue in American politics in the early 1960s.

King organized and led marches for blacks' right to vote, desegregation, labor rights and other basic civil rights. Most of these rights were successfully enacted into United States law with the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

King and the SCLC applied the principles of nonviolent protest with great success by strategically choosing the method of protest and the places in which protests were carried out in often dramatic stand-offs with segregationist authorities. Sometimes these confrontations turned violent. King and the SCLC were instrumental in the unsuccessful Albany Movement in Albany, Georgia, in 1961 and 1962, where divisions within the black community and the canny, low-key response by local government defeated efforts; in the Birmingham protests in the summer of 1963; and in the protest in St. Augustine, Florida, in 1964. King and the SCLC joined forces with the Student Nonviolent Coordinating Committee (SNCC) in Selma, Alabama, in December 1964, where SNCC had been working on voter registration for a number of months.

King, representing SCLC, was among the leaders of the so-called "Big Six" civil rights organizations who were instrumental in the organization of the March on Washington for Jobs and Freedom in 1963. The other leaders and organizations comprising the Big Six were: Roy Wilkins, NAACP; Whitney Young, Jr., Urban League; A. Philip Randolph, Brotherhood of Sleeping Car Porters; John Lewis, SNCC; and James Farmer of the Congress of Racial Equality (CORE). For King, this role was another which courted controversy, as he was one of the key figures who acceded to the wishes of President John F. Kennedy in changing the focus of the march. Kennedy initially opposed the march outright, because he was concerned it would negatively impact the drive for passage of civil rights legislation, but the organizers were firm that the march would proceed.

The march originally was conceived as an event to dramatize the desperate condition of blacks in the South and a very public opportunity to place organizers' concerns and grievances squarely before the seat of power in the nation's capital. Organizers intended to excoriate and then challenge the federal government for its failure to safeguard the civil rights and physical safety of civil rights workers and blacks, generally, in the South. However, the group acquiesced to presidential pressure and influence, and the event ultimately took on a far less strident tone.

As a result, some civil rights activists felt it presented an inaccurate, sanitized pageant of racial harmony; Malcolm X called it the "Farce on Washington," and members of the Nation of Islam who attended the march faced a temporary suspension.

The march did, however, make specific demands: an end to racial segregation in public school; meaningful civil rights legislation, including a law prohibiting racial discrimination in employment; protection of civil rights workers from police brutality; a $2 minimum wage for all workers; and self-government for the District of Columbia, then governed by congressional committee.

Despite tensions, the march was a resounding success. More than a quarter of a million people of diverse ethnicities attended the event, sprawling from the steps of the Lincoln Memorial onto the National Mall and around the reflecting pool. At the time, it was the largest gathering of protesters in Washington's history. King's I Have a Dream speech electrified the crowd. It is regarded, along with Abraham Lincoln's Gettysburg Address, as one of the finest speeches in the history of American oratory. President Kennedy, himself opposed to the march, met King afterwards with enthusiasm - repeating King's line back to him; "I have a dream", while nodding with approval.

Throughout his career of service, King wrote and spoke frequently, drawing on his long experience as a preacher. His "Letter from Birmingham Jail", written in 1963, is a passionate statement of his crusade for justice. On October 14, 1964, King became the youngest recipient of the Nobel Peace Prize, which was awarded to him for leading non-violent resistance to end racial prejudice in the United States.

King and SCLC, in partial collaboration with SNCC, then attempted to organize a march from Selma to the state capital of Montgomery, for March 25, 1965. The first attempt to march on March 7 was aborted due to mob and police violence against the demonstrators. This day has since become known as Bloody Sunday. Bloody Sunday was a major turning point in the effort to gain public support for the Civil Rights Movement, the clearest demonstration up to that time of the dramatic potential of King's nonviolence strategy. King, however, was not present. After meeting with President Lyndon B. Johnson, he attempted to delay the march until March 8, but the march was carried out against his wishes and without his presence by local civil rights workers. Filmed footage of the police brutality against the protesters was broadcast extensively, and aroused national public outrage.

The second attempt at the march on March 9 was ended when King stopped the procession at the Edmund Pettus Bridge on the outskirts of Selma, an action which he seemed to have negotiated with city leaders beforehand. This unexpected action aroused the surprise and anger of many within the local movement. The march finally went ahead fully on March 25, and it was during this march that Willie Ricks coined the phrase "Black Power" (widely credited to Stokely Carmichael).

In late March, 1968, Dr. King went to Memphis, Tennessee in support of the black sanitary public works employees, represented by AFSCME Local 1733, who had been on strike since March 12 for higher wages and better treatment: for example, African American workers, paid $1.70 per hour, were not paid when sent home because of inclement weather (unlike white workers).

On April 3, Dr. King returned to Memphis and addressed a rally, delivering his "I've been to the Mountaintop" address.

King was assassinated at 6:01 p.m. April 4, 1968, on the balcony of the Lorraine Motel in Memphis, Tennessee. Friends inside the motel room heard the shots and ran to the balcony to find King shot in the throat. He was pronounced dead at St. Joseph's Hospital at 7:05 p.m. The assassination led to a nationwide wave of riots in more than 60 cities. Five days later, President Lyndon B. Johnson declared a national day of mourning for the lost civil rights leader. A crowd of 300,000 attended his funeral that same day. Vice-President Hubert Humphrey attended on behalf of Lyndon B. Johnson, who was meeting with several advisors and cabinet officers on the Vietnam War in Camp David. Also, there were fears he might be hit with protests and abuses over the war. The city quickly settled the strike, on favorable terms, after the assassination.

Two months after King's death, escaped convict James Earl Ray was captured at London Heathrow Airport while trying to leave the United Kingdom on a false Canadian passport in the name of Ramon George Sneyd. Ray was quickly extradited to Tennessee and charged with King's murder, confessing to the assassination on March 10, 1969 (though he recanted this confession three days later). Later, Ray would be sentenced to a 99-year prison term.

Besides winning the 1964 Nobel Peace Prize, in 1965 the American Jewish Committee presented King with the American Liberties Medallion for his "exceptional advancement of the principles of human liberty." Reverend King said in his acceptance remarks, "Freedom is one thing. You have it all or you are not free."

As of 2006, more than 730 cities in the United States had streets named after King. King County, Washington rededicated its name in his honor in 1986. The city government center in Harrisburg, Pennsylvania is the only city hall in the United States to be named in honor of King.

In 1966, the Planned Parenthood Federation of America awarded Dr. King the Margaret Sanger Award for "his courageous resistance to bigotry and his lifelong dedication to the advancement of social justice and human dignity."

In 1971, Dr. King was awarded the Grammy Award for Best Spoken Word Recording for his Why I Oppose the War in Vietnam.

In 1977, the Presidential Medal of Freedom was awarded posthumously to King by Jimmy Carter.

King is the second most admired person in the 20th century, according to a Gallup poll.

King was voted 6th in the Person of the Century poll by TIME.

King was elected the third Greatest American of all time by the American public in a contest conducted by the Discovery Channel and AOL.
