AMERICA remembers the Rev. Dr. Martin Luther King Jr. as a national champion of civil rights. But he was an international icon, too — and like many icons, his legacy was used for a range of purposes that moved far beyond, and even ran counter to, his famous dream.

Indeed, it was King’s “I have a dream” speech that sealed his global fame. We’ve all seen photos of the hundreds of thousands marching in 1963 Washington. But thousands also marched that day in London, Tel Aviv and Accra, Ghana.
