NGOs: A New History of Transnational Civil Society is an academic work that explores the development and evolution of non-governmental organizations (NGOs) and their role in shaping global civil society. The book examines how NGOs emerged, how they operate across national borders, and how they influence international politics, development, humanitarian work, and social movements. It provides a historical and analytical perspective on transnational activism and the growing importance of civil society in global governance. Suitable for university students and researchers, it offers a critical understanding of how NGOs have become key actors in addressing global challenges.
