In addition to this, a new chapter 11, 'Direct Democracy', provides cutting-edge analysis of referendums, citizen assemblies, and other forms of democratic innovations. Additional analysis of gender equality, poverty, and climate change is provided from a global perspective in the new chapter 22, which examines the impact of public policies. And finally, a new chapter 25, 'Promoting and Protecting Democracy', draws on the latest developments, such as global shifts towards authoritarian regimes and autocracy, and international relations perspectives, to present a clear overview of democracy promotion. -- Section I: Theories and Methods -- Section II: The Historical Context -- Section III: Structures and Institutions -- Section IV: Actors and Processes -- Section V: Public Policies -- Section VI: Beyond the Nation-State Published online: 27 July 2023
