The aim of this thesis is a critical reconstruction of the postcolonial reflection on space. The thesis mirrors a twofold operation within postcolonial critiques of space: on the one hand, the critical contestation of different types of spatiality of colonial domination, on the other hand, the conceptual alternatives provided in response by postcolonial critique, that offers new imagines and tools to rethink of political spaces in an empowering way. In order to mirror this twofold move, the thesis is structured in two parts, preceded by a first chapter that illustrates a fundamental strategical move of postcolonial critique, namely the critical entanglement of scattered spaces that have been set apart and segregated by colonial dominations (Chapter 1). A pars destruens follows, concentrating on the postcolonial contestation of specific colonial spaces (Chapter 2), and exploring postcolonial critiques to modern geography and cartography, meant as instruments of colonial power/knowledge that build a global space that is inherently asymmetrical, to which postcolonial studies respond by way of developing critical counter-cartographies (Chapter 3). The following pars construens, on the other hand, concentrates on two main concepts of the postcolonial conceptualization of space, namely the planet and the border. The planet is investigated as an ā€œover-writing of the globeā€, and as an occasion for postcolonial studies to reflect on questions of ecology and cosmopolitics (Chapter 4). Chapter 5 reconstructs the multi-faceted levels of a complex postcolonial re-signification of the notion of border. Eventually, a concluding section recalls all the aforementioned arguments, with particular reference to the notions of dislocation, diaspora, and translation.
