The decade of the 1960s brought heightened activism in the civil rights movement: through boycotts and demonstrations, African Americans demanded an end to segregated public facilities and jobs. Some whites responded with violence, attacking demonstrators, and bombing a black church in Pine Bluff in 1963. Some civil rights demonstrators were shot. Local leaders worked tirelessly, at times enlisting the support of national figures such as Dick Gregory and Stokely Carmichael, to help bring about change over the period. Voter registration drives that enabled increased black political participation, selective buying campaigns, student protests, and a desire among white local business leaders to avoid damaging negative media portrayals in the national media led to reforms in public accommodations.
