The purpose of this work is to present the samba-plot as an object of History Teaching, acting as a structuring component for the formulation of historical questions and research paths, in the classroom. For this, we approached the samba-enredo as a historical problem, starting from its constitution as a musical genre. Among the sambas-enredos with an Afro-Brazilian theme, a representative sample of approaches and treatments at key moments, such as the beginning of the 1960s, with African parades, and the year 1988, the centenary of the Abolition. The analysis of the Afro-Brazilian theme sambas-plot has the potential to produce questions on themes related to slavery, the condition of the black population in the post-abolition period, as well as in the approach of black trajectories , in which the protagonism of these characters in history is the main motto. One of these sambas deserved special attention in this work, O papel e o mar, by Renascer de Jacarepaguá, 2017. In this work, the writer Carolina Maria de Jesus and the sailor João Cândido engage in a fictional dialogue, permeated by representations about race relations in our society, social invisibility and the duty of memory that hangs over them, symbols of the fight against racism. A set of sambas to be worked on in the classroom are presented at the end of this work, in which the social production of samba and the trajectories of the two characters emerge as tangible constructions of the post-abolition and black diaspora in Brazil.
