The film is based on the novel Memórias do Distrito de Diamantina, written by João Felicio dos Santos (who has a small role in the film as a Roman Catholic pastor). It is a romanticized retelling of the true story of Chica da Silva,[2] an 18th-century Africanslave in the state of Minas Gerais, who attracts the attention of João Fernandes de Oliveira, a Portuguese sent by Lisbon with the Crown's exclusive contract for miningdiamonds, and eventually becomes his lover, rises into power and into the Brazilian high society of the time. Moreover, João quickly lets the intendant and other authorities know that he can be bribed, and gets onto their corruption scheme. Eventually Lisbon hears of João's (and Xica's) excesses and sends an inspector. José, a political radical, is another main character, who provides Xica refuge.
In 1996, the now defunct TV station Rede Manchete successfully adapted the film plot to the telenovela format, directed by Walter Avancini, written by Walcyr Carrasco and starring Taís Araújo as the title character. This telenovela marked the first time an Afro-Brazilian actress played the lead role on a TV show. In 2005, SBT re-aired Xica da Silva.
