"I Have a Dream" is a public speech that was delivered by American civil rights activist and Baptist minister, Martin Luther King Jr., during the March on Washington for Jobs and Freedom on August 28, 1963. In the speech, King called for civil and economic rights and an end to racism in the United States. Delivered to over 250,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, D.C., the speech was a defining moment of the civil rights movement and among the most iconic speeches in American history.Beginning with a reference to the Emancipation Proclamation, which declared millions of slaves free in 1863, King said "one hundred years later, the Negro still is not free". Toward the end of the speech, King departed from his prepared text for a partly improvised peroration on the theme "I have a dream", prompted by Mahalia Jackson's cry: "Tell them about the dream, Martin!" In this part of the speech, which most excited the listeners and has now become its most famous, King described his dreams of freedom and equality arising from a land of slavery and hatred.Jon Meacham writes that, "With a single phrase, King joined Jefferson and Lincoln in the ranks of men who've shaped modern America". The speech was ranked the top American speech of the 20th century in a 1999 poll of scholars of public address. The speech has also been described as having "a strong claim to be the greatest in the English language of all time".



The March on Washington for Jobs and Freedom, also known as simply the March on Washington or The Great March on Washington, was held in Washington, D.C., on Wednesday, August 28, 1963. The purpose of the march was to advocate for the civil and economic rights of African Americans. At the march, final speaker Dr. Martin Luther King Jr., standing in front of the Lincoln Memorial, delivered his historic "I Have a Dream" speech in which he called for an end to racism.The march was organized by A. Philip Randolph and Bayard Rustin, who built an alliance of civil rights, labor, and religious organizations that came together under the banner of "jobs and freedom." Estimates of the number of participants varied from 200,000 to 300,000, but the most widely cited estimate is 250,000 people. Observers estimated that 75–80% of the marchers were black. The march was one of the largest political rallies for human rights in United States history. Walter Reuther, president of the United Auto Workers, was the most integral and highest-ranking white organizer of the march.The march is credited with helping to pass the Civil Rights Act of 1964. It preceded the Selma Voting Rights Movement, when national media coverage contributed to passage of the Voting Rights Act of 1965 that same year.
