Other volunteers staff a tent and welcome visitors to pick up supplies, including free books. The 381 Movement, a group that grew from protests following the police killing of George Floyd in Minneapolis in late May, is named for the successful 381-day Montgomery, Ala., bus boycott in 1955-56 against racially segregated seating that propelled Rosa Parks and Dr. Martin Luther King Jr. to national attention. The modern movement’s goal is to offer solutions to racial and social injustice based on research, learning, legislation and volunteer initiatives that “empower, educate and evolve the community.”
