In this introduction to Nineteenth-Century Literature in Transition: The 1890s, the editors, Dustin Friedman and Kristin Mahoney, situate the contents of the collection in relationship to the larger objectives of the Nineteenth-Century Literature in Transition series, which aims to move beyond existing preconceptions of individual decades within the nineteenth century by producing new characterizations enabled by recent critical methodologies. This volume highlights in particular the role that work attending to the transnational, ecocriticism, digital humanities, and new approaches to gender and sexuality might play in reshaping our understanding of a period often referred to as “the Naughty Nineties.” This work, the editors argue, enhances our understanding of the nineteenth century’s closing years in their full complexity, dynamism, and intellectual ferment and makes a case for the relevance of perspectives from the 1890s regarding issues that still preoccupy us today.
