The Anthem Companion to Immanuel Wallerstein explores many of the topics central to Wallerstein’s understanding of the modern world-system and offers a comprehensive guide to the full range of his work.Immanuel Wallerstein, one of the most influential yet controversial sociologists of the past half-century, is a touchstone in innumerable debates about globalisation and the power of capitalism, the nature of development in the modern era, and how to come to grips with widespread inequalities while recovering the potential for social change. The Anthem Companion to Immanuel Wallerstein offers a compelling guide to his writings and ideas, his influences and reception, and the reasons for his enduring significance, with eleven original interpretive essays written by a distinguished group of international scholars. Importantly, the contributors also advance Wallerstein’s work into neglected areas such as climate change, global pandemics, racism, and gender and demonstrate his importance, not just to debates in his own intellectual context, but to those of our own times as well. This companion provides a multifaceted tool for thinking with Wallerstein, while showing where those engaging with Wallerstein’s thought can take his work in the contemporary world.
