Reimagines the American 19th century through a sweeping interdisciplinary engagement with oceans genres and timeEmergent Worlds relocates nineteenthcentury America from the land to the oceans and seas that surrounded it. Edward Sugden argues that these ocean spaces existed in a unique historical fold between the transformations that inaugurated the modern eraamp8212colonialism to nationalism mercantilism to capitalism slavery to freedom and deferent subject to free citizen. As travellers workers and writers journeyed across the Pacific Atlantic and Caribbean Sea they had to adapt their political expectations to the interstitial social realities that they saw before them while also feeling their very consciousness particularly their perception of time mutate. These four domainsamp8212oceanic geography historical folds emergent politics and dissonant timesamp8212in turn provided the conditions for the development of three previously unnamed genres of the 1850s the Pacific elegy the black counterfactual and the immigrant gothic.In telling the history of these emergent worlds and their importance to the development of the literary cultures of the US Americas Sugden proposes narratives that alter some of the most enduring myths of the field including the westward spread of US imperialism the redemptionist trajectory of black historiography and the notion that the US Americas constituted a new world. Introducing a new generic vocabulary for describing the literature of the 1850s and crossing over oceans and languages Emergent Worlds invokes an alternative nineteenthcentury America that provides nothing less than a new way to read the era.
