This thesis scrutinises the material on post World War II Swedish architecture produced by the Swedish Public diplomacy organisation "Svenska institutet" ("The Swedish Institute") during the period of 1945 through 1976. The outset is the dilemma encountered by every such organisation: how can the projected narrative of the own nation relate to as many countries as possible, without becoming too general? And how can the organisation address specific countries, without excluding others?By employing a two-sided model of interpreting the material, where it on the one hand is interpreted from the universal properties projected on the narrated architecture, and on the other hand from the particular ideological notions related to the same, the thesis suggests that the Swedish Institute continously relates the architecture to a West-European and American context by consistently connecting its universal properties to particular ideological notions orientated towards the West.The results underline the malleability in regard to ideological notions connected to modernist architecture. Earlier research in the Swedish context has focussed on how modernist architecture in Sweden, under the local tag "funktionalism", was established in regard to a Swedish audience as a particular Swedish architecture by relating it to a alleged continuos Swedish tradition, as well as to notions of a a progressive welfare state. By studying a similar material, though aimed towards a foreign audience, the thesis suggests that these allegations constitue an elucidatory example of how national and ideological narratives can form within the framework of technological-ideological dynamics of modernist architecture.
