In this chapter, the authors trace the antecedents of critical literacy by exploring how each of them arrived to the concept, and how these herstories connect with the roots and current trends in critical literacy. The authors also explore the link between popular education and critical literacy, the critiques to critical literacy, and offer three examples of global critical literacy praxis. The authors close the chapter with an invitation to rethink the current role of scholars in the advancement of critical literacies in tandem with social movements.
