In this talk Natalia will present a general overview of the main arguments of her PhD Thesis, together with an illustration of findings from her research-sites. She will address the empirical puzzle of how to explain variation in ethnic reintegration levels across sub-national units, and provide arguments to answer the question of whether and how ethnic reintegration is possible in post-conflict divided societies. She argues that after an ethno-territorial war the political dynamics of a post-conflict setting generate a post-conflict game that involves ethnic leaders from majority and minority groups hindering the prospects of ethnic reintegration, and co-ethnic leaders within a kinship system that reinforces such dynamics. In this context, the timely engagement of third parties is necessary in order 1) to break the post-conflict game that hinders the process of ethnic reintegration, and 2) to empower alternative political dynamics that benefit such process. Natalia further explains the conditions under which alternative post-conflict scenarios of enclavisation, assimilation and homogenisation take place revealing the nuances and complexities of the ethnic reintegration process at large.
