Political geography is the study of the relationship between political processes and geographical space. It examines how territory, place, location, and landscape shape political power, and conversely, how political decisions and conflicts reshape the geographical world. At its core, the subfield asks a deceptively simple question: why is political power organized and exercised the way it is across the Earth's surface, and what are the consequences of that spatial organization?
The discipline is not a single unified theory but a field of competing and overlapping traditions. Its history is marked by periods of dominance by particular approaches, followed by critiques and reorientations. Understanding the field requires tracing these shifts, as the questions political geographers ask today are often direct responses to the failures or limitations of earlier frameworks.
The modern subfield emerged in the late nineteenth and early twentieth centuries, primarily in Europe, as a formal academic discipline. Its earliest practitioners were concerned with the state as the primary container of political life. The central problem was explaining the rise, power, and competition of states in a world being rapidly carved into colonial empires.
The most influential early figure was the German geographer Friedrich Ratzel, who drew on contemporary biology to conceptualize the state as a living organism that grows, competes for resources, and requires Lebensraum (living space) to thrive. This organic analogy, while scientifically dubious, framed the state as a spatial entity whose power was tied to its territory. Ratzel's work gave rise to the concept of geopolitics, a term later popularized by the Swedish political scientist Rudolf Kjellén. Geopolitics, in this classical sense, was the study of how geographical factors—location, resources, access to seas, natural barriers—determine the foreign policy and strategic destiny of states.
This tradition reached its apex in the work of British geographer Halford Mackinder. In his famous 1904 paper, Mackinder argued that the Eurasian "heartland" was the pivotal region of world power. Whoever controlled this interior zone, he reasoned, would be positioned to dominate the "world island" of Eurasia and ultimately the globe. Mackinder's theory was a form of environmental determinism: it claimed that fixed geographical features dictated the long-term balance of power. While the specific predictions of the heartland theory were never fully realized, the framework established a powerful template. For decades, political geography was largely synonymous with the study of the state's strategic position, its borders, and its competition with other states.
The classical approach had significant limitations. It tended to treat the state as a natural, almost inevitable entity rather than a historically specific political form. Its focus on interstate rivalry often served to justify imperial expansion and national aggrandizement. Moreover, its deterministic logic left little room for human agency, culture, or internal political dynamics. By the mid-twentieth century, these weaknesses had become apparent, and the field entered a period of crisis and redefinition.
In the decades after World War II, human geography as a whole underwent a "quantitative revolution," and political geography was not immune. Scholars sought to make the discipline more scientific by adopting the methods of the natural sciences: hypothesis testing, statistical analysis, and the search for general laws of spatial behavior.
In this vein, political geographers turned their attention to the internal structure of states. They studied electoral geography, analyzing voting patterns to identify spatial regularities in political behavior. They developed models of how administrative regions, transportation networks, and urban systems were organized. The work of Richard Hartshorne, for instance, shifted focus from the state's external strategy to its internal "integration"—the processes by which a state's territory is bound together into a functional whole. The central question became not "how do states compete?" but "how do states function as spatial systems?"
This approach brought rigor and a new set of tools to the field, but it also stripped away much of its critical edge. By treating the state as a neutral container for social processes, it avoided questions of power, inequality, and conflict. The search for universal laws often produced banal descriptions of spatial patterns without explaining the political struggles that created them. By the 1970s, this positivist framework was under attack from multiple directions.
The most significant challenge came from Marxist and neo-Marxist geography. Scholars like David Harvey and Doreen Massey argued that space is not a neutral stage on which politics happens, but is actively produced by economic and social forces. The central problem for this approach was explaining how capitalism, as a mode of production, shapes and is shaped by geographical organization.
From this perspective, the state is not a neutral arbiter but an instrument of class power, tasked with maintaining the conditions for capital accumulation. Political geography became the study of how the state manages the spatial contradictions of capitalism—for example, the tension between the mobility of capital and the fixity of infrastructure, or the uneven development between regions. The geography of the state, including its borders, its internal administrative divisions, and its urban policies, was understood as a product of class struggle and capital's need for spatial order.
This critical turn had a profound and lasting impact. It introduced questions of inequality, exploitation, and social justice into the heart of political geography. It also broke down the artificial separation between the "political" and the "economic," showing how political power is deeply embedded in economic structures. However, Marxism's focus on class as the primary axis of social division was soon challenged for neglecting other forms of identity and oppression.
Beginning in the 1980s and accelerating through the 1990s, political geography absorbed the broader "cultural turn" in the social sciences. This movement drew on post-structuralism, feminism, and postcolonial theory to argue that power operates not only through states and economies but also through language, culture, and everyday practices. The central question shifted from "who controls what territory?" to "how is political identity constructed and contested through space?"
This reorientation opened up several new areas of inquiry. Geopolitics was reimagined as "critical geopolitics," which examines how political leaders, intellectuals, and the media produce geographical knowledge that justifies particular policies. Instead of asking what the "real" strategic importance of a region is, critical geopoliticians ask how a region is represented as important, dangerous, or backward in political discourse. The 2003 invasion of Iraq, for example, was analyzed not just as a military action but as a product of a particular "geopolitical imagination" that divided the world into civilized and uncivilized zones.
The cultural turn also brought questions of nationalism and ethnicity to the fore. Political geographers began to study how national identity is tied to specific landscapes, how borders create and reinforce distinctions between "us" and "them," and how minority groups contest their marginalization through spatial practices. Feminist political geographers, such as Gillian Rose, argued that the state and the nation are not gender-neutral but are built on assumptions about masculinity and femininity. They examined how public spaces are gendered, how women's political participation is spatially constrained, and how the private sphere is itself a site of political struggle.
This approach has been enormously influential, but it has also been criticized for sometimes losing sight of material power. A focus on discourse and representation can obscure the brute realities of military force, economic coercion, and physical violence. The field has therefore moved toward approaches that attempt to hold the material and the cultural together.
Today, political geography is a pluralistic field with no single dominant paradigm. The major traditions—classical geopolitics, quantitative political geography, Marxist geography, and critical/cultural approaches—coexist, often in productive tension. Contemporary scholars draw on these traditions selectively, combining them as their research questions demand.
Several themes characterize the current landscape. One is the problematization of territory itself. Rather than treating territory as a fixed, given container of sovereignty, scholars now examine how territory is actively made, maintained, and transformed. This has led to interest in "assemblage theory," which views the state not as a unified actor but as a loose collection of heterogeneous elements—laws, bureaucracies, infrastructure, technologies, and people—that are constantly being assembled and reassembled. The state, in this view, is an effect of these ongoing processes rather than a pre-existing entity.
Another major theme is the relationship between political geography and the Anthropocene, the proposed geological epoch in which human activity is the dominant influence on the Earth's systems. Political geographers ask how environmental change, resource scarcity, and climate migration are reshaping political power. This includes studying "environmental geopolitics," which examines how environmental crises are securitized and used to justify new forms of control, as well as questions of environmental justice, where the unequal distribution of environmental harms is understood as a political issue.
The field has also become more global in its scope. While early political geography was dominated by European and North American scholars and concerns, contemporary work increasingly draws on perspectives from the Global South. Scholars examine postcolonial state formation, the legacies of imperial borders, and the political geographies of development and underdevelopment. This has challenged the assumption that the European nation-state is the universal model of political organization, highlighting instead the diversity of political spatial forms.
The enduring contribution of political geography is its insistence that politics is always spatial. Political power is never exercised in a vacuum; it is always located, always tied to specific places, always organized through territory and networks. The field's various approaches offer different tools for understanding this spatiality—from the strategic calculations of classical geopolitics to the discursive critiques of critical geopolitics, from the structural analysis of Marxism to the identity-focused inquiries of the cultural turn. What unites them is a shared conviction that to understand politics, one must understand geography, and to understand geography, one must understand power.
