In the contemporary world of high-speed communication technologies and porous national borders, empire building has shifted from colonizing territories to colonizing knowledge. Hence the question of whose voices, experiences and theories are reflected in discourse is more important now than ever before. Yet the global production of knowledge in the social sciences is, like the distribution of wealth, income and power, structurally skewed towards the global North. This collection seeks to initiate the task of closing that gap by opening discursive spaces that bridge current global divides and inequities in the production of knowledge. This chapter provides an overview of criminologies of the global periphery and introduces readers to the diverse contributions on and from the global South that challenge how we think and do criminology and justice.
