Latina/o literary engagements with war include a wide variety of texts that touch on more than a century of US militarism and encompass a broad range of genres and perspectives. This body of work includes memoirs by soldiers and novels set during various military conflicts (often based on the authors’ own experiences), as well as short stories, plays, poems, and essays that reflect on, question, and problematize Latina/o participation in war. Just as Latina/o individuals and peoples occupy a variety of positions vis-à-vis the US nation-state—as conquered and colonized populations, as internal “minorities,” and as migrants and refugees—so, too, have Latina/o texts that take up war reflected a variety of positions. Taking an expansive view of war that includes movements of military-backed annexation and colonization, this literature may include Latina/o literary and cultural engagements with the annexation of Texas in 1845, the Mexican-American War (1846–1848), and the annexation of Puerto Rico in 1898. These topics sit alongside very different perspectives on US militarism such as those that reflect Latina/o experiences within the US armed forces in World War II, Korea, Viet Nam, Central America, and Iraq. This literature, then, covers works that celebrate and oppose US military action. Although factors such as geopolitical setting, history, ethnicity, and nationality affect the ways Latinas/os have experienced and interacted with US militarism, gender, and sexuality have also played important roles in these articulations. Gender is a necessary category of analysis that facilitates a more nuanced understanding of the way individuals and communities experience war. Just as it is best not to assume that military service for Latinas/os has had a singular or constant meaning (such as an experience of bravery or pride), it is necessary to avoid approaching gender as synonymous with women. Thus a gendered analysis facilitates questioning of the way masculinity and femininity shape and are shaped by questions of violence, military intervention, and national cohesion.
