Black Catholics were involved early on in the Civil Rights Movement, and James Chaney—one of the three victims in the Freedom Summer Murders—was said to be devout. Diane Nash, a prominent lunch-counter demonstrator, Freedom Rider, voter registration advocate, and Student Nonviolent Coordinating Committee (SNCC) co-founder, was also Catholic. Later, Mary Louise Smith preceded Rosa Parks as one of the first people arrested in the runup to the Montgomery bus boycott.
