Recent research into the Moroccan troops who fought in the Spanish Civil War has both drawn from and contributed to insights gained from new historiographical developments in the field of the Spanish conflict as well as other European twentieth-century conflicts. Studies examining the experiences and choices of low-level participants of the war, whether soldiers or civilians – on both the Francoist and republican sides – have increasingly shown that they were players in possession of a certain degree of agency, however limited. That agency allowed these low-level players, whether Spanish or Moroccan, to influence war events to a higher degree than previously thought possible, and has shown that mobilisation for and maintenance of the war effort depended on a certain mixture of coercion and negotiation, even within the more authoritarian Francoist camp. In the European context, the Moroccan participation in the 1936–9 war has its special characteristics, one of which is that its military significance weighed heavier than other colonial contributions to European battlefields between 1914 and 1945, and therefore the agency of Moroccans was more consequential. Nevertheless, it has much in common with other European experiences. A recent collaborative volume on British, French, Spanish and Dutch colonial armies in the first half of the twentieth century, Colonial Soldiers in Europe (2016), edited by Eric Storm and myself, has helped put the Moroccan–Spanish experience in European perspective. Similarities abound, not only in colonial soldiers’ experiences of fighting in foreign lands, but also between the various Western European attempts at controlling, i.e. limiting, the cultural and human consequences of this massive irruption of male warriors into the continent.
