At the end of the march from Selma to Montgomery, protesters gathered at the Alabama State Capitol, where Martin Luther King Jr. gave his "Our God is Marching On" speech, which marked a turning point in the civil rights movement.
"How long? Not long, because no lie can live forever. How long? Not long, you shall reap what you sow. How long? Not long," King said in his speech.
He continued: "How long? Not long, because the arc of the moral universe is long, but it bends toward justice."
