In the post-1945 world, Finnish schools were appointed the new task of fostering democratic values and educating peace-loving citizens. By exploring postwar art and environmental education in Helsinki, understood as means to expand children’s emotional competences, Malinen and Vahtikari provide a unique analysis of the ways educators, children and urban space co-produced the nation in everyday (school) practices. Malinen and Vahtikari show the importance of fully acknowledging the spatial, material and sensory aspects of emotions when discussing children’s emotional formation and historical manifestations of everyday nationalism. To illustrate the adult-children co-creation of different ideas, practices and emotions with respect to the national community, the chapter uses two sets of contemporary sources: educators’ writings and children’s drawings.
