ABSTRACT
This chapter explains the study of borders from the perimeter of nation-states' governing narratives and underline their complex nature, focusing on specific intersections between African migrant's trajectories and national identities in order to "reactivate the constituent moment of the border". The chapter the frontier has to be intended as a mobile and imprecise space within which the borders appear and operate, especially in reference to "colonial situations". The chapter reflects upon borders and frontiers is essential to the analysis that considers citizenship and migration between Europe and Africa as its central theme. Therefore it proposes that we take Lord Curzon's invitation seriously and pause to reflect upon the importance of borders and frontiers for the life of people who move between Africa and Europe. The stories that take place in the space between Europe and Africa can help us to reconceptualize borders in ways that attend to the roles of practice.
