This seminar examines how the digital age has transformed politics around the world, in democratic and authoritarian contexts. Information and communication technologies change how state, society, and market actors interact, and affect the balance of power between political systems and their challengers. Social media facilitates information sharing and collective action with monitorial citizenship on the rise. Technology creates new access points and vulnerabilities; development entails security threats. The course includes four modules: e-democracy (participation, elections and campaigns, social capital and civil society, and public opinion and polarization); online revolutions (resistance, repression, mobilization, authoritarian resilience, censorship, and surveillance); security (cyberwar, new threats, and radicalization); and beyond state boundaries (cooperation, migration, transnational hacktivism, new business models, and cryptocurrencies).
