Final answer:
Martin Luther King Jr.'s 'I Have a Dream' speech called for an end to racial injustice and a society that judges people by their character, not skin color.
Step-by-step explanation:
In his iconic "I Have a Dream" speech, delivered during the March on Washington for Jobs and Freedom in 1963, Martin Luther King Jr. urged people to end racial injustice and come together to build a society where all individuals are judged not by the color of their skin but by the content of their character. He envisioned a harmonious and integrated America that lives out its creed that 'all men are created equal'. King's repeated refrain amplified the power of his vision and called on the crowd to share his dream of racial equality and justice.
