The Grimke Sisters, Sarah and Angelina, were early advocates for abolitionism and women's rights in the 1800s. They traveled throughout the North lecturing about their experiences growing up on a plantation where their father advocated for slavery. After witnessing a slave being beaten at age 5, Sarah taught her personal slave how to read and the sisters became outspoken abolitionists, realizing that both slaves and women lacked equality. They were instrumental in helping to establish the philosophical foundations for the future spread of equality in America.
