Written within the literary conventions of the Romantic movement and published decades before other Brazilian abolitionist novels, Úrsula (1859) offers a sensitive and nuanced portrayal of enslaved African and Afro-Brazilian characters. While readers follow the story of the plantation owner's daughter Úrsula, her doomed romance with Tancredo, and her uncle's diabolical schemes to entrap her in marriage, the novel's power lies in Reis's characterization of the enslaved Africans Tulio, Susana, and Antero. Shown in all their humanity as they narrate their personal histories and give voice to the abuse and injustices they have endured, these characters tell of the horrors of the Middle Passage, the daily indignities they face, and the brutality of their masters.
