Cumann na mBan (henceforth CnamB) was founded in April 1914 as a women’s auxiliary organisation whose activities included: fi rst aid; the transportation and concealment of arms, ammunition and despatches; drilling; intelligence and propaganda work; providing for men on the run; prisoner network support and weapons care. The relationship between the CnamB and the Irish Volunteer leadership, has been explored in depth by historians, while the 2018 centenary commemorations drew considerable attention to questions of suff rage and female republicanism within the movement. However, there has been a distinct lack of research conducted on the militaristic aspects of CnamB as an organisation and the material culture surrounding CnamB, namely uniforms, badges and fl ags that survive in public and private possession (Figs. 1-4). This paper will attempt to rectify this and shed light on the merits of interdisciplinary approaches to the study of military regalia.
