Horrors of Slavery announced an abolitionist politics unacknowledged by Romantic-era antislavery activists: place-based, self-liberation initiated and led by Black women. Reworking the abolitionist figure of the sorrowful, enslaved Black mother, Wedderburn celebrated his mother, Rosanna, who demanded that his enslaver father manumit him, and championed his grandmother, Talkee Amy, as a higgler and obeah woman who “trafficked on her own account.” Similar freedom practices are then traced throughout The History of Mary Prince. Prince’s repeated petit marronage demanded enslavers’ acknowledgment of her kinship with her parents and husband. As a higgler, like Talkee Amy, Prince used the produce from the provision grounds to assert freedom in fugitive markets. Wedderburn and Prince’s life narratives brought stories of Black women’s place-based freedom practices to a white audience.
