Book excerpt: Drawing on a range of theoretical and empirical perspectives, this volume examines the roles strategic communications play in creating social media messaging campaigns designed to engage in digital activism. As social activism and engagement continue to rise, individuals have an opportunity to use their agency as creators and consumers to explore issues of identity, diversity, justice, and action through digital activism. This edited volume situates activism and social justice historically and draws parallels to the work of activists in today’s social movements such as modern-day feminism, Black Lives Matter, #MeToo, Missing Murdered Indigenous Women, and We Are All Khaled Said. Each chapter adds an additional filter of nuance, building a complete account of mounting issues through social media movements and at the same time scaffolding the complicated nature of digital collective action. The book will be a useful supplement to courses in public relations, journalism, social media, sociology, political science, diversity, digital activism, and mass communication at both the undergraduate and graduate level.
