This work looks at everyday places in order to understand how boundaries are enacted and re-employed, shifted and displaced in post-Dayton Bosnia and Herzegovina. Post-Dayton boundaries correspond to practices of demarcation that may or may not entail geographic delimitations and that have been reorganized by the Dayton Peace Agreement in ways that have assured them a more prominent role in sociopolitical life in BiH. While engaging in an effort to conceptualize borders and boundaries, this thesis argues that boundaries are dependent on practices, which confers upon them a precarious status and indicates that they might be changed. Boundaries may thus be re-employed (in the sense of diverting its original meaning and employing a different one); shifted and displaced, but also much more, as it will be exposed here: crossed, minimized, subverted, dismissed, disdained, but also reinforced, reaffirmed and celebrated. It is thus looking at the everyday that this work makes sense of those boundaries, knowing, however, that they are permeated with contradictions and may be enacted in different ways by different people. The everyday, which usually receives our daily inattention, will be considered here a relevant analytical category through which undertake this research. Indeed, the everyday cannot be reduced to the unimportant or the banal, as mere residual or the remnants of the political. Rather, it is profoundly related to all activities, and encompasses them with all their differences and their conflicts; it is their meeting place, their bond, their common ground (Lefebvre, 1991: 97), and it thus provides for connection and mediation between categories often presented as dichotomies such as public and private, the exceptional and the routine (Lefebvre, 2008: 16). It is in and through the everyday that those tensions are played, the disputes are fought and appropriations and even transformation take place. The research was undertaken in Sarajevo and Mostar, two of the main cities in BiH. More specifically, this research looks at everyday places within these cities, such as schools, streets, squares, cafés, coach station and shopping malls, which might be enacted as the very (ethnonational, local/international) boundaries or the arena in which those boundaries are diverted and displaced. This thesis, therefore, provides for an alternative account to more official narratives about ethnonational divisions, as well as questions clear-cut distinctions between the local and the international in post-Dayton BiH.
