In their largest bail out effort to date, the National Bail Out collective announced Tuesday morning that their third annual Mother’s Day campaign freed 100 black mothers—and raised an additional $1 million to set even more incarcerated women free.

The organization’s landmark achievement was part of the third annual Black Mama’s Bail Out campaign. In the week leading up to Mother’s Day, the coalition of black-led organizations, activists and lawyers led events in 35 different cities across the U.S. to raise funds for—and awareness about—cash bail, a system which keeps many low-income defendants behind bars simply because they don’t have the money to free themselves before trial.
