Through the analysis of relevant writings and thoughts of architectural theorists, sociologists and historians on the architecture and society in Yugoslavia, this thesis focuses on demonstrating the importance of the cohesion of art and society in the creation of a city. Special attention is given to the humanization of space, anthropocentrism, and the creation of cities for the people in socialist Yugoslavia. It illustrates how architecture was shaped in accordance with the vision of an egalitarian society based on the ideals of working-class emancipation and equality. It explores socialist modernization within the framework of socialist and capitalist values in a specific utopian vision of society. The research provides insights into the significance of modernist architecture in shaping the urban landscape of Yugoslav cities, constructing not only historical cores but also modern districts of the future. Representative modernist buildings symbolizing social progress and national pride are analysed, including ambitious cultural centres, healthcare institutions and hotel complexes. Through architecture, the unity and continuous aspiration for progress and unity are portrayed. The aim of this thesis is to create a portrayal of the construction and modernization of socialist Yugoslavia, with the emergence of some of the most beautiful modern architectural structures and symbols of unfinished modernizations. Through an interdisciplinary approach encompassing the history of architecture, social sciences and humanities, as well as urban studies, this thesis offers insight into the complex and dynamic relationship between Yugoslav society, modernist architecture, and the construction of a humane city of the future.
