This article traces the history of teaching Vulgar and Late Latin (LVLT) at Finnish universities from the mid-19th century to the present, focusing on the University of Helsinki. Drawing on archival sources, we examine changes in teaching programmes, degree requirements and thesis output. We show how LVLT was gradually integrated into Latin studies through philological renewal, Romance philology and epigraphic research, peaking in a ‘boom’ from the 1960s to the 1990s. Key figures such as Veikko Väänänen and Iiro Kajanto were central to embedding LVLT in teaching and research. However, recent structural reforms and cuts to staff and courses have contributed to a decline in LVLT instruction.
