Abstract
This chapter examines how social movements in the developing world and ‘bottom-up’ alternative politics, supported by new technology and globalized networks, can strengthen democracy. It first traces the origins of social movements, showing how different forms of social movements have emerged and been influential during different periods, before discussing the main theoretical perspectives about why this is so and how we should understand this phenomenon. It then considers past and present social movements and alternative politics in the developing world, focusing on three categories: movements concerned with democracy and governance, movements concerned with identity politics, and movements concerned with social justice. It also describes the increasing globalization of social movements and explains what makes such movements successful.
