The aim of this dissertation is to investigate the presence of violence as a reference in the creation of Oswald de Andrade s first book of poetry, Poesia Pau Brasil, published in 1925. We seek to analyze the issues that permeate his poems and the relationship they have with Brazilian history, starting from the perspective and artistic and political trajectory of the São Paulo poet. We seek to understand how Oswald read Brazil and how violence permeates not only his first book of poetry, but his entire bibliography. Thus, we will bring important texts that enable us to have this reading of Poesia Pau Brasil, as well as texts that underpin the concept of violence, such as Violência (2017), by philosopher Marilena Chaui. We will analyze some poems from Pau Brasil under the pretext of unearthing Brazil s repressed history, and understand how Oswald presents in his first poetic work the violence that was born in the colonial period.
