This volume meditates on the various meanings of legitimation and expands on the notion that language can be used to gain or preserve it by demonstrating the added impact of other modes in specific examples of political and institutional discourse. The book draws on a multilayered framework that builds on and integrates work from both critical discourse analysis and social semiotic traditions, as well as the work of philosophers such as Habermas, Weber, and Rousseau, to show how it might be applied in practice to analyse and understand myriad forms of discourse. The volume focuses on examples from political campaign spots, which highlight various modes, including images, film, oratory, and color, but are also of global relevance and scale, highlighting their unique and complex position at the nexus between legitimation and multimodality. Offering a new analytical framework for understanding legitimation across a range of discursive contexts, this book will be of particular interest to students and scholars in discourse analysis, multimodality, political science, psychology, design, and education.
