As it is well known, the demographic phenomenon of migrations is not a new milestone on humanity's history. In fact, human displacement –due to voluntary or forced causes– within a state or among different nations has characterized our species from the first gatherers and hunters. However, 2015 has been a year clearly marked by the word “refugee” and by the sad reality of human displacement. Migration, as the voluntary action of leaving a certain territory, and displacement, as the forced version of it, both they are essential elements to take into account when thinking about governance and citizenship in host territories. On the one side, it affects to the concept of citizenship; on the other, it impacts on the way governance is conducted –mainly– in terms of the degree of political inclusiveness of democracy. This article aims to review, from the theoretical point of view, the main contributions made during the last years in the field of «migrants and citizenship». It aims also to relate the existing literature to the concept of «Athens Syndrome». This concept points out to the idea that, as happened during the democratic regime established during the Ancient Greece, the democratic system use to coexist with structural political exclusions. Thus, regarding the increasing number of migrants and displaced people into western countries, it becomes imperative to examine their political situation and the normative consequences that it has in our nowadays increasing diverse political societies.
