Is modernism the most apt term for the literary efflorescence that took place in the first decades of the twentieth century across a range of regional and cultural contexts? What are the advantages and disadvantages of considering the heterogeneous collective of the Americas together? This essay spotlights significant Latinx writers, texts, and exchanges seldom included in conversations about American modernism, as it discusses the development of Latinx literature and Spanish-language literatures within the geographical bounds of what is now the US. Doing so reveals the crucial contributions of Latinx poets and the role of translation in fueling literary innovation.
