Sarah Moore Grimké (November 26, 1792 – December 23, 1873) was an American abolitionist, widely held to be the mother of the women's suffrage movement. Born and reared in South Carolina to a prominent, wealthy planter family, she moved to Philadelphia, Pennsylvania, in the 1820s and became a Quaker, as did her younger sister Angelina. The sisters began to speak on the abolitionist lecture circuit, joining a tradition of women who had been speaking in public on political issues since colonial days, including Susanna Wright, Hannah Griffitts, Susan B. Anthony, Elizabeth Cady Stanton, and Anna Dickinson. They recounted their knowledge of slavery firsthand, urged abolition, and also became activists for women's rights.
