The influence of the constitution respectively the constitutional legislation on a social integration and a state functionality is an almost unexplored area. In this respect Bosnia and Herzegovina represents no exception. The increasing tendencies of disintegration, vast ethno-political competition as well as a standstill of any reforms in the country whatsoever indicate the necessity of a detailed engagement with the Bosnian constitutional history. Furthermore, the question of their influence on the functionality of the state and the social integration is being raised. On the one hand this work aims to explain the substance of the term "social integration" in the Bosnian context. On the other hand, it goes into the question: "In which constitutional era Bosnian society or the state Bosnia and Herzegovina operated as an integrating and functional unity the best?" In the first part of the work, the theoretical explanation of the triangle state-constitution-integration is being carried out. In the second part, all existing Bosnian and Herzegovinian constitutions are being studied in regards to their integrative potential, their influence on inter-ethnic relations as well as on the functionality of the state. Thereby, the question of continuity respectively discontinuity between former Bosnian constitutions and the one of Dayton, which implicitly forms the central guideline of the work, is being extensively illustrated. In the conclusive part a summary of the results is given and a final assessment of the present social integration of the country is being ensued regarding the current crisis of the Bosnian statehood.
