The Grimké sisters gained wide recognition through their writing and public speaking. In response to opposition by male abolitionists, Sarah wrote Letters on the Equality of the Sexes. They were threatened by pro-slavery mob violence. When Angelina married in 1838, she and her husband created a home for Sarah as well. The women retired from public speaking, but retained their influence on the next generation. Articulate and determined, the Grimké sisters were a major force in the move of anti-slavery women away from ladies auxiliaries in abolitionist associations and toward radical feminist political activism.
