Gloria Evangelina Anzaldúa (1942-2004) was a critical theorist of feminism and cultural theory. Born on the Mexico-United States border and self-declared chicana, lesbian and political activist, the author has been conquering space within philosophical studies and political theories of gender. Her thinking, as well as her territorial and bodily experience are marked by the visceral and intimate way in which she produces and transmits her texts. Winding between the lines of theory, literature, poetry, narrative and self-history, Anzaldúa removes the reader from his academic comfort and inserts him in the frontier universe. In her main book “Borderlands / La Frontera: The New Mestiza” (1987) the author uses “bilingualism”. That is, the intersection of languages that merge into one, such as the mixture of Spanish, English, Tex-Mex, Pachuco and slang, producing what she calls “a way of living”, a “living-between-languages”. In this space, the “New Mestiza” emerges an awareness that encompasses multiple experiences and that has the capacity to confront the concept of identity. The objective of this work is to investigate this concept and how it relates to identity, above all, how Anzaldúa mobilizes poetry to reach the consciousness of the “New Mestiza”.
