From 1836 to 1838 two southern sisters, Angelina and Sarah Grimke, gave anti-slavery speeches in New England.
They described the horrors they had seen as the daughters of slave owners.
After Angelina wrote a pamphlet begging southern women to free their slaves, she was told never to return to the South.
The Grimke sisters were attacked not just for their ideas but also for daring to voice them in public.
Several ministers issued a letter warning of the dangers to a woman’s character “when she assumes the place and tone of man as a public reformer.”
In reply, Sarah Grimke emphasized that “whatever is right for a man to do, is right for a woman to do.”
In 1833 white Bostonian Lydia Maria Child published one of the first American books against slavery: An Appeal in Favor of That Class of Americans Called Africans.
Her book persuaded several important Bostonians, such as Senator Charles Sumner, to call for an end to slavery.
