In , Edward Watts labels this impulse "primordialism" and reveals its consistent presence over the span of nineteenth-century American print culture. In dozens of texts, Watts tracks episodes in which varying accounts of pre-Columbian whites attracted widespread attention: the Welsh Indians, the Lost Tribes of Israel, the white Mound Builders, and the Vikings, as well as two ancient Irish interventions. In each instance, public interest was ignited when representations of the group in question became enmeshed in concurrent conversations about the nation’s evolving identity and policies. Yet at every turn, counternarratives and public resistance challenged both the plausibility of the pre-Columbian whites and the colonialist symbolism that had been evoked to create a sense of American identity. By challenging the rhetoric of primordialism and empire building, dissenting writers from Washington Irving to Mark Twain exposed the crimes of conquest and white Americans’ marginality as ex-colonials.
