This chapter lays the theoretical foundation for the book by disentangling the myriad discourses and interpretations of digital sovereignty from the perspective of the Global South and emerging power alliances. It argues that BRICS countries symbolize the “rise of the rest” in an increasingly multipolar world, their digital policies critical to the future shape of global internet, and digital governance. In this book, the idea of digital sovereignty itself is viewed as a site of power contestation and knowledge production. Specifically, the chapter identify seven major perspectives on digital sovereignty in a complex discursive field: state digital sovereignty, supranational digital sovereignty, network digital sovereignty, corporate digital sovereignty, personal digital sovereignty, postcolonial digital sovereignty, and commons digital sovereignty. The chapter highlights the affinities and overlaps as well as tensions and contradictions between these perspectives on digital sovereignty with brief illustrative examples from BRICS countries and beyond. While a state-centric perspective on digital sovereignty is traditionally more salient especially in BRICS contexts, increasing public concern over user privacy, state surveillance, corporate abuse, and digital colonialism has given ascendance to an array of alternative perspectives on digital sovereignty that emphasize individual autonomy, indigenous rights, community well-being, and sustainability.
