This book-the second edition ofThe Palgrave Handbook of Global Approaches toPeace-brings together thirty-nine chapters by leading and emerging scholars to explore peace as a concept, policy, and practice. The handbook examines theoretical frameworks, including cosmopolitanism, feminist perspectives, human security, Gandhian philosophy, and liberal peace, alongside domestic practices in Rwanda, Singapore, Canada, Russia, and China. New chapters address contemporary developments in peace studies, peace education, artificial intelligence, and peace-related challenges in East Asia (Japan), the Middle East, and South America. The handbook also analyzes how regional and global institutions-the Arab League, ASEAN, the African Union, the EU, the ICC, the OECD, and the United Nations-influence and foster peace worldwide. Covering theoretical, disciplinary, domestic, regional, institutional, alternative, and transitional approaches, this comprehensive handbook serves as a critical resource for academics, policymakers, practitioners, and students committed to understanding and advancing peace in the twenty-first century.
