Where On what did the Grimk sisters base their argument for equal rights for women?

The Grimké sisters, Angelina and Sarah, based their argument for equal rights for women on the principles of moral and natural law, as well as their own experiences as women in a patriarchal society. They emphasized the inherent equality of all human beings, drawing parallels between the oppression of women and the enslavement of African Americans, which they actively opposed. Their advocacy was rooted in a belief that women deserved the same rights and opportunities as men, including education and participation in social reform.
