Development became a central sociological concern after 1945, as newly independent nations sought to close the gap with industrialised states. The debate pivots on a single question — is underdevelopment an original condition to be overcome by imitation, or a produced condition generated by the very structure of the world economy? Modernisation theory took the first view; dependency and world-systems theory took the second. Understanding this reversal is the analytical heart of the topic.

Modernisation theory

Modernisation theory, dominant in the 1950s and 1960s, treated development as a universal, linear transition from traditional to modern society. It drew on evolutionary sociology and Parsonian pattern variables, contrasting ascription, particularism and diffuseness with achievement, universalism and specificity.

Walt Rostow's The Stages of Economic Growth (1960), pointedly subtitled A Non-Communist Manifesto, offered the canonical model — five stages from traditional society, through the preconditions for take-off, the take-off, the drive to maturity, to the age of high mass consumption. The decisive stage is take-off, requiring a rise in investment, a leading manufacturing sector and supportive institutions. Development thus meant replicating the Western path, aided by capital, technology and modern values. Others in this school included David McClelland, who located the spur in the psychological need for achievement.

The critique

Modernisation theory attracted powerful criticism. First, it is ethnocentric, treating the Western trajectory as universal and tradition as merely an obstacle rather than a resource. Second, it is ahistorical, ignoring colonialism, which reshaped and drained the very societies now labelled backward. Third, it assumes internal causes of underdevelopment while neglecting external and structural ones. Fourth, its unilinear stages ignore the fact that late developers face a world already dominated by industrial powers, so the paths are not comparable. These objections opened the space for a radical, historically grounded alternative rooted partly in the ideas of Karl Marx.

Dependency theory

Dependency theory, emerging from Latin America, inverted the modernisation thesis. Underdevelopment is not a starting point but an outcome — the flip side of development elsewhere. Andre Gunder Frank coined the arresting phrase the development of underdevelopment, arguing that a chain of metropolis–satellite relations siphons surplus from peripheral regions to metropolitan centres, at every level from the world city to the rural hinterland. Satellites experience their strongest autonomous growth precisely when ties to the metropolis weaken, as during wars or depressions.

Frank's model was complemented by Raul Prebisch's structural economics on declining terms of trade, and by Paul Baran's work on the blocked development of the periphery. Fernando Henrique Cardoso later refined the picture with associated-dependent development, showing that some industrialisation can occur within dependency. Critics charge dependency theory with circularity, an overemphasis on exchange rather than production, and difficulty explaining the rise of the East Asian economies.

World-systems theory

Immanuel Wallerstein absorbed dependency insights into a more supple historical framework. His unit of analysis is not the nation-state but the modern world-system — a single capitalist world-economy emerging in the "long sixteenth century". This system has a global division of labour organised into three zones — the core, the periphery and a mediating semi-periphery that stabilises the whole by acting as both exploiter and exploited.

Crucially, Wallerstein allows mobility between zones, so individual states can rise or fall even though the hierarchical structure endures. The system operates in long rhythms of expansion and contraction (Kondratieff waves) and is held together by an interstate political order. World-systems analysis thus historicises and globalises the development debate. It is criticised for economic reductionism and for underrating the autonomy of states and cultures.

Assessment

  • Modernisation locates causes inside nations; dependency and world-systems locate them in global relations.
  • Dependency tends towards a static core–periphery binary; world-systems adds the dynamic semi-periphery.
  • All three have been unsettled by globalisation, the rise of China and India, and post-development critiques that question the goal of development itself.

How to use this in the exam

Frame the answer as a debate, not a catalogue. State the core question — is underdevelopment original or produced — and let each theory answer it. Use signature phrases precisely: Rostow's take-off, Frank's development of underdevelopment, Wallerstein's semi-periphery. Marks come from evaluation, so weigh each theory's blind spots and end with a contemporary twist, such as East Asian success or globalisation, to show the debate is live. For Indian relevance, link the discussion to colonial drain, dependent industrialisation and India's shifting position within the world-system.
