Postcolonial studies have transformed critical thinking in the humanities and social sciences. But its anthropocentrism ignores the more-than-human worlds that are hugely important to many indigenous cultures. How can the field move forwards in order to better understand ideas of materiality and the non-human? This is the first book that brings together emerging, influential and interdisciplinary work on posthumanism to advance postcolonial research. The text explores advances around the concepts of political ontology and posthumanism to show how postcolonial studies can draw further on work from geography, anthropology, politics, literature, and indigenous studies. Bridging the gap that has emerged between innovative theoretical and empirical demands, and the insufficient conceptual means of orthodox postcolonialism, it proposes new trajectories through which to advance postcolonial scholarship, even seeking to radicalize it in the process. The book will also address how relational and posthumanist approaches can themselves learn from postcolonial histories, and so respond effectively to ongoing legacies of contemporary injustice.
