The last two decades have seen an unprecedented expansion of brutal border regimes around the world. People racialised as migrants are systematically disenfranchised, dispossessed and often exposed to forms of organised violence such as immigration detention and deportation. Despite the widespread political and scholarly debate on migration, the relationship between contemporary border regimes and the history of colonialism has largely been overlooked. This gap is particularly evident in psychology, a discipline traditionally dominated by an emphasis on individuals and lacking acknowledgment of social, political, and structural processes. In this chapter, we examine border violence as being produced by a combination and intersection of power structures and relations that maintain the colonial global orders. Furthermore, we critically analyse how psychology in general, and community psychology in particular, have approached these issues. In doing so, we rely on our observations and lived experiences as community organisers, practitioners, and researchers engaged with “border thinking.” Ultimately, we hope that the reflections shared in this chapter can contribute to an ongoing conversation on how community psychologists, inspired by the decolonial turn, can actively engage in solidarities-in-action with individuals and communities on the frontline of border struggles in local and global contexts.
