The virtue of theater is that it can take things out and show them through emotion. It is not a purely intellectual matter that forces people to memorize or follow a model to the letter. On the contrary, it offers the possibility of evaluating the story of a human being who stands in front of an audience, exposes himself and generates countless emotions. The interesting thing about all this is that in the theater of memory there is an intention of truth and of closeness to historical reality. This generates an additional effect. It moves viewers to wonder: "how come I didn't know about this?" People attend, observe, admire, and investigate, all simultaneously. This promotes an imperious will to come out of ignorance, and begin to see the world with critical eyes, and not veiled. In order to address the relationships and scenarios that are interwoven in the staging of memory through theater in the Entreacto Festival, the following degree project will be organized into six sections. In the first section, the generalities of the Historical Memory Center are described, namely, its research functions, publications, actions and initiatives. In the second section, an analysis of the theater is carried out as an action not only aesthetic, but also ethical and political, and the performative act is related to memory. In the third section, the field of collective memory, identity construction and staging are explored, with Ricœur as an interlocutor. Finally, sections five and six seek to explore the relationship between collective memory, emotion and staging at the Entreacto Festival as a tool for building and defending reparation.
