Southern states tightened restrictions on both free and enslaved blacks, trying to get the free blacks to go somewhere else and keep the enslaved ones by prohibiting teaching literacy and severely restricting preaching. Military readiness was looked into: South Carolina built a series of arsenals to ensure weapons would be available. Northern states shared much the same feeling: a proposal to create a college for African Americans in New Haven was overwhelmingly rejected (see New Haven Excitement), and schools in New Hampshire and Connecticut were destroyed by group violence (see Noyes Academy and Canterbury Female Boarding School).
