45 Years Ago Today Martin Luther King, Jr. Had a Dream

This week and next week you will hear many speeches (including tonight, Barack Obama's acceptance speech as the Democratic nominee), but 45 years ago today, in a 15-minute speech captured here on YouTube, Martin Luther King Jr. delivered one of the greatest orations of the 20th century, a hopeful vision during one of the most fractious periods of American social history that has since served as a rallying point for our country's better nature.
