This work presents reflections on the African ancestry as an element of the formation and self-affirmation of the narrator-character's black identity in the work O Pequeno Principe Preto, by Rodrigo France. Initially, we made considerations about the work and its destination for children and youth readers, in which its educational aspects that focus on affectivity, construction of the identity of the black child and African ancestry are highlighted. Race relations are also discussed based on the impressions presented by O Pequeno Principe Preto character in his interactions with other characters in the narrative. The work consists of the analysis of the narrative, from the approach of the concepts of children's and youth literature, by Colomer (2017); Black-Brazilian literature, from the perspective presented by Cuti (2010); ancestry, according to Oliveira (2012); Machado (2014), and identity, from the perspective of Hall (2006). The reading of O Pequeno Principe Preto highlights the African ancestry as a powerful element in the construction and self-affirmation of the black children identity.
