This work intends to investigate the incidence of the ethnic component in the nation, imagined by the narrators of the following three Chilean novels: Mariluan, a drama in the countryside (1862), by Alberto Blest Gana, The Queen of Rapa Nui (1914), by Pedro Prado and Butamalon (1994), by Eduardo Labarca. The theoretical foundation that supports the evolutionary analysis of the three novels is conferred by the concept of nation, analyzed historiographically by Benedict Anderson, Eric Hobsbawm and Partha Chatterjee that, previously imagined, ends up being a political community that negotiates its diversity.
