During the nineteenth century, romanticism became central to how Mexicans engaged in practices of self-definition. Romanticism in Mexico was an intellectual and artistic movement that was at once autonomous and connected to transcultural influences. As evidenced by the works of historians and literary scholars, as well as novelists, politicians, poets, and antiquarians from the period, romanticism was gendered in terms of women’s participation and representation, and in themes such as love, family, virtue, domesticity, and eroticism. Women were critical to the transmission of romanticism in quotidian practices of attending theater and opera, hosting salons, and instilling appreciation for poetry and the natural world in their families and their communities. Romanticism also exercised a profound influence on how Mexicans thought about ethnicity, race, and nationalism. In their quest for a unique national identity, Mexican intellectuals looked to the indigenous past and celebrated mestizaje as the foundation of Mexico’s cultural patrimony, even as they persisted in exclusionary practices toward their indigenous and casta compatriots. Romanticism offers a fruitful area to reevaluate well-studied themes of Mexican history, particularly its complex relationship with nationalism, modernization, gender, and the politics of ethnicity and race.
