Martin Luther King Jr. remains a towering figure, known around the country and the world for his civil rights activism and moving speeches.

In honor of MLK Day 2023, here are four stories from the Atlas Obscura archives that delve into often-overlooked—or long hidden—aspects of the civil rights movement, from King’s dedication to another cause to the people who supported his efforts and the government agents who surveilled them.

On Martin Luther King Jr. Day, thousands of Americans join parades, volunteer, or just take a few minutes to contemplate the legacy of a man devoted to peace and equality.
