Archaeologists should always have their say in the interpretation of the archaeological record. Moreover, they should not allow those interpretations to be misappropriated by others, whether politicians, journalists or specialists of other disciplines. By contending that borders are a timely topic for archaeological attention, Emily Hanscam and Brian Buchanan (2023) make a decisive epistemological step forward within the field, also opening up the potential of the discipline's specialised knowledge for wider dissemination and impact. They advance from a straightforward position: the argument that re-bordering in the contemporary world, notably through the increasing fencing of borders (Bissonnette & Vallet 2020), often originates in a normative and normalising discourse on the past. The best example, according to the authors, is Hadrian's Wall, which appears as a common justification for the building of contemporary walls on a growing number of international borders. Their text unfolds a comparison between the archaeological findings about that one short segment of the Roman limes in northern Britain and the supposed properties of the contemporary infrastructure on the US/Mexico border, which successive US presidents have sought to reinforce—chief among them Donald Trump.
