*Spies of Mississippi* reveals a hidden history: a secret spy agency created by the state of Mississippi to uphold segregation and white supremacy. Operating from an office within the State Capitol, this anti-civil rights organization received public funding and broad authority. Initially a propaganda arm, the Commission grew into a full-scale spy operation. The story is documented in over 146,000 pages of State-preserved files – firsthand historical records that illuminate a little-known chapter in America's struggle for Civil Rights.
