Book excerpt: Spanning Indigenous settings in Africa, the Americas, Aotearoa/New Zealand, Australia, Central Asia and the Nordic countries, this book examines the multifaceted language reclamation work underway by Indigenous peoples throughout the world. Exploring political, historical, ideological, and pedagogical issues, the book foregrounds the decolonizing aims of contemporary Indigenous language movements inside and outside of schools. Many authors explore language reclamation in their own communities. Together, the authors call for expanded discourses on language planning and policy that embrace Indigenous ways of knowing and forefront grassroots language reclamation efforts as a force for Indigenous sovereignty, social justice, and self-determination. This volume will be of interest to scholars, educators and students in applied linguistics, Ethnic/Indigenous Studies, education, second language acquisition, and comparative-international education, and to a broader audience of language educators, revitalizers and policymakers.
