Dr. Martin Luther King Jr. delivered his iconic speech during the March on Washington for Jobs and Freedom on August 28, 1963. The exigence, or the urgent issue that prompted the speech, was the pervasive racial prejudice and discrimination faced by African-Americans during that time. King addressed the need for racial equality, civil rights, and an end to segregation in the United States. His speech resonated deeply with the audience and became a powerful call for justice and equality for all individuals, regardless of race.
