The daily life of the border area in Imotska krajina and Herzegovina is the subject of this thesis in which the aim is to establish how border determines and limits day-to-day life of border community as well as to what extent it separates people from both sides of the border and in what extent it connects them. The methodology of the thesis is based on field research conducted in the settlement of Runovići, the site directly bordering with Bosnia and Herzegovina, that was carried out by means of semi-structured interviews and surveys. The hypothesis underlying this thesis defines the border as a limited factor that as a physical barrier significantly affects the lives of local people. The thesis starts with the analysis of the development of scientific research of borders that began in the late 19th century after which it developed within diffusionism and symbolic anthropology. From 1990s border research experiences its full development with wide range of research approaches. In addition to those characteristics of the territorial aspect, the border has begun to be viewed in its cultural characteristics which affected recognizing the border area as a unique cultural area with presence of the specific border identity. Due to hybrid identity, the border is seen as the place where two separate communities merge which is opposed with seeing the border as the place where they are completely separated. The study of the border between Croatia and Bosnia and Herzegovina in the area of Imotski and Herzegovina initially focuses on historical circumstances of the border separation upon formation of the border in 1718 and afterwards on the recent era characterized by absence of the border designations within Yugoslavia and re-separation that followed Croatian independence. In the case of the developments within the Croatian state, the second part of the observed aspect is the Croatian entry into the European Union and the Schengen area that outlines the further development of the border separation with Bosnia and Herzegovina. The essence of these changes are the daily activities of the border community relating to the land and social relations maintained by border crossing and cross-border encounters.
