Modernity, Globalisation, and World-Systems Theory

Immanuel Wallerstein's world-systems theory, developed from the 1970s onward, rejected the conventional sociological practice of studying individual nation-states in isolation and instead argued that the relevant unit of analysis since the sixteenth century has been a single capitalist 'world-system' divided into a 'core' of wealthy, technologically advanced states, a 'periphery' of states supplying raw materials and cheap labour, and a 'semi-periphery' occupying an intermediate, often exploitative-and-exploited position. Building on earlier dependency theory associated with Andre Gunder Frank and Raúl Prebisch, Wallerstein argued that underdevelopment in the periphery is not a prior 'natural' state that development will eventually overcome but is actively produced and maintained by the core's structural extraction of surplus, making global inequality a systemic rather than incidental feature of capitalism.

Anthony Giddens offered a different but complementary account of globalisation centred on the concept of 'time-space compression' and 'disembedding,' the process by which social relations are lifted out of local contexts and restructured across indefinite spans of time and space through abstract systems like money and expert knowledge. Giddens characterised late or 'high' modernity as fundamentally reflexive: institutions and individuals alike must continuously revise practices in light of new information in a world where tradition can no longer be taken for granted, producing what he called 'ontological insecurity' alongside expanded individual freedom and choice, most visible in his analysis of transformed intimacy and personal identity in a globalised, detraditionalised world.

Manuel Castells's trilogy The Information Age argued that the late twentieth-century revolution in information and communication technology produced a qualitatively new social structure, the 'network society,' organised around flows of capital, information, images, and power that increasingly bypass and reconfigure the territorial nation-state. Castells distinguished the 'space of flows,' the dominant logic of global elites and networked capital, from the 'space of places,' the lived, localised experience of most ordinary people, arguing that this growing disjuncture generates new forms of identity-based resistance, from religious fundamentalism to environmentalism to feminist and indigenous movements, as people reassert local and particular identities against homogenising global flows.

Saskia Sassen's concept of the 'global city' complements these frameworks by showing how globalisation, rather than dissolving territory, concentrates command-and-control functions of the world economy in a small number of cities such as New York, London, Tokyo, and increasingly Mumbai and Shanghai, which simultaneously host highly paid transnational professional elites and a large low-wage service workforce, often composed of migrant labour, that sustains those elites' daily lives — producing new landscapes of inequality within, not just between, nations.

Taken together, these theories caution against treating 'globalisation' as a single, uniform, or automatically benign process of convergence; each framework instead emphasises structured inequality, whether between core and periphery states, between reflexive elites and those with fewer resources to navigate detraditionalised risk, between the space of flows and the space of places, or between global city elites and their service-sector dependents, offering sociology students multiple analytical lenses for understanding contemporary phenomena from outsourced manufacturing to remote digital labour platforms.
