Wikipedia is a major source for public information. Wikipedia materials are proliferated across the Internet of Things, are reused in journalism and social media, and power search engines and digital assistants (Ribeiro et al. 2021; Miz et al. 2020). Yet Wikipedia’s impact on public understanding of the past, particularly our medieval pasts, is under-researched. This article argues for the significance of Wikipedia for medievalists in terms of how it may shape research, pedagogy, and public-facing work. We examine three case studies—articles for the ‘Black Death,’ the ‘Viking Age,’ and ‘Old English literature’—to explore how the medieval is forged, defined by us as crafted and created, ‘on-Wiki.’ We discuss what these forgings suggest about public understanding, desires, and interests, and the ideas about the past that emerge as a result. Our case studies demonstrate varied approaches to Wiki content, including citation review, readings of version histories, and pageview analysis. It is intended that this article provokes further discussion of Wikipedia as a site of medieval public history and inspires our colleagues to engage as critics, editors, teachers, or activists.
