This Element examines women warriors as vehicles of mobilisation. It argues that women warrior figures from the mid-nineteenth century until the end of the Second World War are best understood as examples of ‘palimpsestic memory’, as the way they were represented reflected new contexts while retaining traces of legendary models such as Joan of Arc, and of ’travelling memory’, as their stories crossed geographical borders and were re-told and re-imagined. It considers both the instrumentalisation of women warriors by state actors to mobilise populations in the world wars, and by non-state actors in resistance, anti-colonial and feminist movements. Fell’s analysis of a broad range of global conflicts helps us to understand who these actors were, what motivated them, and what meanings armed women embodied for them, enabling a fresh understanding of the woman warrior as an archetype in modern warfare.
