Under the current cartographies of globalism, where frontiers mutate, vacillate, and mark the contiguity of discourse, questioning the Spanish border seems a particularly urgent task. The volume engages a wide spectrum of ambivalent regions-subjects that currently are, or have been seen in the past, as spaces of negotiation and contestation. However, they converge in their perception of the Spanish nation-space as a historical and ideological construct that is perpetually going through transformations and reformations. This volume advocates the position that intellectual responsibility must lead us to engage openly in the issues underlying current social and political tensions.
