In 1935, Fascist Italy invaded independent Ethiopia, a member of the League of Nations. To a small and neutral country like Sweden, without a direct colonial heritage and largely isolated from the affairs of the colonized world, the war served as a touchstone for the quality of the League and received extensive attention in the press. It gave rise to great indignation in public opinion, further spurred by Swedish citizens’ half a century history of involvement in the Ethiopian modernizing project. Swedish sympathies for the Ethiopians developed to an extent which hitherto had not existed with regard to any other African or Asian people, long before the anti-colonial movements of the 1960s. The article is limited to giving an outline of a research proposal, seen against the backdrop of the massive popular manifestations in Sweden in the late summer of 1935, immediately before the outbreak of the war in October. It argues that the Italo-Ethiopian conflict and identification with Ethiopia brought Sweden into a new, international and global community and thereby contributed to a self-image of Sweden as a modern and democratic society, as reflected in the formation of public opinion. The source material, the Swedish press, is remarkably rich and hitherto not used in research. The conflict animated a plurality of networks, contributing to the rise of an anti-colonial public opinion in the Swedish press. The conflict brought Sweden closer to world events and introduced to Swedish readers a debate about the colonial world order.
