Political geography asks how power is organized across space, how territory is claimed and contested, and how the very knowledge we produce about geopolitics shapes political realities. From the late nineteenth century onward, the subfield has been pulled between two fundamental tensions: between environmental and human agency in explaining political outcomes, and between state-centric and relational views of political space. Each major framework emerged as a response to what its proponents saw as the blind spots of earlier approaches, and many of these frameworks remain in productive tension today.
The first systematic attempt to explain political power geographically was Environmental Determinism (1880–1920). Its proponents argued that climate, terrain, and natural resources directly shaped the character and destiny of nations. Friedrich Ratzel, for instance, likened the state to a biological organism whose growth depended on its natural environment. This framework provided a seemingly scientific justification for colonialism and imperialism, but its crude causal logic—reducing complex political histories to environmental conditions—came under heavy fire after World War I, when the idea that geography dictated national fate could not account for the war's political origins.
Possibilism (1900–1950), associated especially with the French geographer Paul Vidal de la Blache, offered a direct counterweight. Where determinism saw nature as a dictator, possibilism saw nature as a stage offering multiple possibilities, with human culture and decision-making selecting among them. This shift from environmental compulsion to human agency opened space for studying how different societies shape their political landscapes in diverse ways. Possibilism did not fully replace determinism—both coexisted for decades—but it established a lasting sensibility that political outcomes are never simply read off the physical map.
Running alongside these environmental debates was Classical Geopolitics (1890–1945), a state-centric framework that treated the world as a chessboard of great powers competing for strategic advantage. Halford Mackinder's heartland theory, which argued that control of Eurasia's interior was the key to global dominance, exemplified this approach. Classical geopolitics shared determinism's interest in large-scale geographical constraints, but it focused on the strategic calculations of states rather than on environmental causation more broadly. The framework became deeply entangled with imperial ambitions and, later, with Nazi expansionist ideology, leading to its widespread discrediting after 1945. For decades afterward, the very term "geopolitics" was treated with suspicion in academic geography.
The mid-twentieth century brought a dramatic methodological shift. Spatial Science (1950–1970) imported quantitative methods from economics and sociology, seeking to model political patterns—voting behavior, the location of capitals, the geometry of borders—through statistical analysis and spatial laws. Its positivist ambition was to make political geography a predictive science. This framework largely set aside the environmental debates of earlier generations, treating space as a neutral grid to be measured rather than a cultural or political construct. Spatial science produced valuable tools, but its assumption that political behavior could be reduced to mathematical regularities soon drew criticism for ignoring meaning, perception, and power.
Behavioral Geography (1960–1980) emerged partly as a corrective within the same positivist tradition. Rather than assuming that people respond mechanically to spatial stimuli, behavioral geographers studied how individuals perceive their environment and how those perceptions influence decisions—from where to vote to how to navigate a city. Behavioral geography shared spatial science's commitment to empirical rigor, but it narrowed the focus to cognitive processes, using methods like mental mapping and survey research. Its contribution was to show that political spatial behavior is mediated by subjective images of the world, not just objective distances. Yet by remaining within a positivist framework, behavioral geography did not challenge the deeper assumptions about power and ideology that later frameworks would confront.
Marxist Geography (1970–1990) broke decisively with positivism. Drawing on David Harvey's and others' work, Marxist geographers argued that political space cannot be understood apart from capitalism's logic of accumulation, uneven development, and class struggle. The state, in this view, is not a neutral container but an instrument for managing capitalist crises and reproducing class relations. Marxist geography absorbed spatial science's interest in patterns of inequality but reinterpreted them as products of political economy rather than as natural spatial laws. It also revived the critical edge that had been lost since classical geopolitics' discrediting, though now directed against capitalism rather than in service of state power.
Political Ecology (1980–Present) grew directly out of Marxist geography's concern with power and inequality, but it broadened the analysis to include environmental access, resource conflicts, and the role of non-class identities. Where Marxist geography tended to foreground class, political ecology showed that struggles over land, water, and forests are simultaneously shaped by gender, race, ethnicity, and colonial legacies. This framework absorbed Marxist political economy while adding attention to ecological conditions and local knowledge. Political ecology remains one of the most active frameworks today, especially in research on environmental justice, climate conflicts, and development politics.
The 1990s witnessed a wave of frameworks that challenged the state-centric and Eurocentric assumptions of earlier political geography. Critical Geopolitics (1990–Present) drew on poststructuralist theory to argue that geopolitical knowledge is not a neutral description of the world but a form of power that actively constructs the realities it claims to describe. Instead of asking which state controls which territory, critical geopoliticians examine how politicians, mapmakers, and intellectuals produce representations of "us" and "them," "heartlands" and "peripheries." This framework transformed classical geopolitics from a strategic practice into an object of critique, showing that even academic geopolitics had been complicit in imperial projects. Critical geopolitics remains a leading approach, particularly in studies of security discourse, media representations, and foreign policy narratives.
Feminist Political Geography (1990–Present) challenged the masculine assumptions embedded in every earlier framework. From the state as a rational actor to the public sphere as the only site of politics, feminist geographers argued that political space is gendered through and through. They brought attention to the body as a political territory, to the household as a site of sovereignty and resistance, and to the ways that nationalism and militarism depend on gendered divisions of labor. Feminist political geography coexists with critical geopolitics as a parallel critique, but it insists that power operates not only through discourse but also through embodied practices and intimate relations. Its intersectional turn has increasingly connected gender to race, class, and sexuality.
Postcolonial Political Geography (1990–Present) took aim at the Eurocentrism that had shaped political geography from its origins. Environmental determinism, classical geopolitics, and even Marxist geography had largely told stories centered on Europe and North America. Postcolonial geographers argued that colonialism is not a finished chapter but an ongoing structure that shapes borders, sovereignty, and political identities across the Global South. This framework draws on subaltern studies and postcolonial theory to recover marginalized perspectives and to show how colonial cartography and territorial divisions continue to produce conflict. Postcolonial political geography overlaps with critical geopolitics in its suspicion of universal knowledge claims, but it focuses more specifically on the legacies of empire and the politics of decolonization.
The most recent frameworks have pushed political geography in new directions while remaining in dialogue with the critical turns of the 1990s. Actor-Network Theory (ANT) (2000–Present), imported from science and technology studies, treats political power as an effect of networks that include not only humans but also technologies, documents, buildings, and other non-human actors. For ANT, the state is not a pre-existing entity but a precarious achievement held together by passports, border fences, databases, and bureaucratic routines. This framework challenges the discourse-centered approach of critical geopolitics by insisting that material objects have agency in political processes. ANT has been especially influential in studies of border security, infrastructure, and environmental governance.
Non-Representational Theory (NRT) (2000–Present) goes further in questioning the primacy of representation and discourse. Drawing on affect theory and practice theory, NRT argues that political life is shaped by pre-cognitive affects, embodied habits, and mundane practices that cannot be captured by analyzing texts or representations. Where critical geopolitics examines how political actors represent the world, NRT asks how political subjects are formed through rhythms, atmospheres, and sensory encounters. This framework has been used to study protest movements, everyday nationalism, and the emotional geographies of war. NRT and ANT share an interest in materiality and practice, but NRT is more focused on affect and embodiment, while ANT emphasizes relational networks.
Today, political geography is a pluralistic field. The leading active frameworks—Political Ecology, Critical Geopolitics, Feminist Political Geography, Postcolonial Political Geography, ANT, and NRT—coexist in a landscape of productive disagreement. They broadly agree that power is relational rather than simply territorial, that knowledge is never neutral, and that political space is produced through social relations rather than given by nature. But they disagree on what drives political spatiality: discourse (critical geopolitics), material networks (ANT), affect and practice (NRT), gendered and embodied experience (feminist political geography), or colonial and capitalist structures (postcolonial and political ecology approaches). Many researchers combine frameworks, using feminist insights to enrich political ecology or ANT to study border infrastructure. Older frameworks have not disappeared entirely: spatial science methods remain useful for analyzing electoral patterns, possibilism's emphasis on human agency continues as a background assumption, and classical geopolitics is studied critically as a historical object. The subfield's enduring tensions—between structure and agency, representation and materiality, state-centric and relational views—ensure that no single framework has the final word.
