This article discusses the role played by war veterans in the various fascist and parafascist groups present in Yugoslavia in the interwar period. The article finds that significant numbers of veterans and the nationalist associations to which they belonged contributed to proposed or actual departures from the democratic norm in interwar Yugoslavia, and were especially supportive of King Aleksandar Karadjordjevic’s dictatorship of 1929–1934. In this respect, they could be termed ‘para-fascist’. The article also notes that whilst the two groups typically identified in the literature as ‘fascist’, the Croatian Ustashe and Serbian/Yugoslav Zbor, fit into the ‘second-wave’ of 1930s fascist forces not usually marked by a strong presence of First World War veterans, their membership and ideological organisation were nevertheless significantly influenced by both the traditions of the war and the men who fought in it.
