Biography can be used in the symbolic sense. For example: “The biography of the president reflects that she has never been in a similar situation”. In this case, the notion of biography refers to the history of life in general, without a material support.
Biography usually begin with the birth of the subject in question (usually a public and famous person) and can even be traced back to their family history (family tree, ancestors, etc.). The biographies whose protagonist has already died come to the moment of his death, while in other cases, the author of the narration can choose up to what time to embrace. As a literary genre, the biography is narrative and expository.
It appears written in the third person, with the exception of autobiographies (where the protagonist is who narrates the actions). Although it may include subjective perceptions of the author and data about the context in which the protagonist lives, the basis of the biography is accurate and precise data, such as dates, names, and places. The basic structure of a biography includes the introduction (a presentation of the character), the development (the narration of the transcendent events of his life) and the conclusion (this is the most subjective segment, with a valuation on the transcendence of the character).
