This is a famous picture of Dr. Martin Luther King Jr. and Malcolm X. Both of these men were Civil Rights activists, and Malcolm X was assassinated in 1965 by Nation of Islam Members, because of their disagreement in his influential messages about Civil Rights.
Dr. Martin Luther King Was Assassinated On This Date In 1968 He was, more than any single man, the voice and the instrument of the second American revolution. He materialized out of the streets and the Jim Crow churches of the South a dozen years ago, preaching brotherhood and nonviolence to a divided and violent land. For a time, incredibly, it worked- until the very forces he had helped set in in motion swept past him and turned the black ghettos of America into battlegrounds.
Martin Luther King assassinated, (prior to this his impact has begun to weaken) King's work before his death was to prove the catalyst for the Civil Rights legislation that followed, however just because laws were being put into place didn't mean that attitudes were going to change with them. King's legacy continued after his death.
