The British newsmagazine Standpoint hit newsstands in England today featuring an article titled “The Troubling Legacy of Martin Luther King” with the subtitle “Newly revealed documents portray the great civil rights leader as a sexual libertine who ‘laughed’ as a forcible rape took place.” The article is written by historian David J. Garrow, winner of the Pulitzer Prize for his 1986 biography, Bearing the Cross: Martin Luther King Jr. and the Southern Christian Leadership Conference.

The story of how the article came to be is striking. Garrow claims to have learned of new information after hearing that King-related materials had been “dumped” on the National Archives website.

Garrow claims that as he went through these materials what he found were never-before-seen documents from FBI files and surveillance summaries, that he writes “silently slipped into public view on the Archives’ lightly-annotated and difficult-to-explore website.” According to his account, many of these came from tens of thousands of government documents from congressional investigations of U.S. intelligence agencies. They are among over 54,000 web links that led to multi-document PDFs, that took him many weeks to go through.

According to an editorial in the same issue, Garrow came to publish this extraordinary piece at Standpoint after it had been accepted by, and then killed at, the Guardian and subsequently rejected by the Atlantic.

Those in the civil rights movement and close to it knew of King’s reputation as a womanizer who cheated on his wife regularly. They thought, as Garrow himself told the U.K. newspaper, the Sunday Times, that he had perhaps about 10 or 12 other women—not the 40 to 45 alleged in the newly discovered FBI files. The charges are so serious and troubling that Garrow reached the conclusion that King’s indifference to, or approval of, a rape he witnessed and encouraged, “poses so fundamental a challenge to the historical stature as to require the most complete and extensive historical review possible.”
