The Prisoners of Geography

How Much Can Maps Really Explain?

Frank Visser / ChatGPT

Tim Marshall's Prisoners of Geography (2015) is one of those books whose central idea is immediately attractive: geography matters, often enormously, and political leaders cannot simply wish away the physical realities of their surroundings. Mountains, rivers, oceans, plains, deserts, natural resources and access to navigable waterways impose constraints on nations and influence their strategic ambitions. Geography, in this account, is not merely the background against which history unfolds. It is one of the principal forces shaping it.

Marshall, a British journalist and foreign-affairs commentator, sets out to explain geopolitics through ten geographical maps, covering Russia, China, the United States, Western Europe, Africa, the Middle East, India and Pakistan, Korea and Japan, Latin America, and the Arctic. His ambition is to make the often bewildering behaviour of states intelligible by showing how their geographical circumstances shape their security concerns, economic possibilities and foreign-policy priorities.

It is an effective journalistic formula. The book is accessible, richly illustrated and full of useful historical observations. It helps readers understand why Russia has repeatedly been concerned about its western approaches, why China is preoccupied with its maritime surroundings, why the United States enjoys an extraordinary strategic advantage from its two oceanic borders, and why the Middle East has become such a persistent arena of international competition.

Yet the very simplicity that makes the book appealing also creates its principal intellectual weakness. Marshall sometimes comes dangerously close to turning geography from an important influence on history into an explanation of history itself. The result is a popular introduction to geopolitics that occasionally slips into geographical determinism.

The central question, therefore, is not whether geography matters. It obviously does. The question is how much explanatory work it can legitimately perform.

1. Geography as destiny: an old idea in modern packaging

The intellectual tradition behind Marshall's book is considerably older than its contemporary presentation might suggest. It belongs to a long history of geographical explanations of political power, from classical observations about climate and civilization to nineteenth-century environmental determinism and twentieth-century geopolitical theories.

One of its most influential predecessors was the British geographer Halford Mackinder, whose 1904 essay on the geographical pivot of history proposed that control over the Eurasian heartland could provide the basis for global dominance. Another important figure was the German geographer Friedrich Ratzel, whose organic conception of the state influenced the development of geopolitical thinking. Later, the American strategist Nicholas Spykman emphasized the importance of the Eurasian coastal rimland rather than the continental heartland.

Marshall does not need to endorse these older theories explicitly to inherit some of their assumptions. His basic proposition is that geographical configurations create persistent strategic incentives. Nations may change their governments, ideologies and economic systems, but the mountains, rivers, plains and coastlines remain.

There is considerable truth in this. A landlocked country faces different economic and strategic challenges from a maritime power. A state surrounded by potential adversaries has different security calculations from one protected by oceans. A navigable river system can facilitate commerce and political integration, while a mountain range can obstruct military movements and communication.

But there is a significant distinction between saying that geography constrains political choices and saying that geography explains them.

A geographical constraint does not dictate a particular political response. It creates a range of possibilities, some more costly than others. Human beings, institutions and governments determine which possibilities are pursued, how they are interpreted and what consequences follow.

This distinction is not merely philosophical. It is essential to understanding the actual workings of international politics.

2. Russia: the geographical explanation and its political dangers

Marshall's chapter on Russia is perhaps the most compelling illustration of his approach. Russia's enormous territory, its relatively exposed western approaches and its historical experience of invasion provide a persuasive explanation for its longstanding concern with strategic depth.

The North European Plain offers relatively few natural barriers between Western Europe and the Russian heartland. Napoleon invaded Russia through this broad corridor in 1812. Nazi Germany did so again in 1941. Russian strategic thinking has understandably been shaped by these experiences.

The absence of secure warm-water ports is another recurring theme. Russia's access to the Baltic and Black Seas is strategically important, but both routes have geographical and political limitations. Its search for greater maritime influence has consequently been a persistent feature of Russian foreign policy.

So far, so good.

The difficulty begins when geographical explanation becomes an implicit justification for Russian expansionism. The desire for strategic depth may help explain Russian anxieties, but it does not establish that neighbouring countries must become Russian buffers. Nor does it explain why their populations should be denied the right to choose their own political and security arrangements.

This distinction is particularly important in the context of Ukraine.

One can understand why Moscow regards NATO's eastward expansion as a strategic concern without accepting the Kremlin's claim to a sphere of influence over its neighbours. Geography may help explain Russian threat perceptions, but those perceptions are also shaped by political ideology, imperial nostalgia, domestic authoritarianism and the personal ambitions of its leadership.

Vladimir Putin's Russia is not simply responding mechanically to the contours of the North European Plain. It is also acting upon a particular historical imagination in which the loss of the Soviet empire is regarded as a national humiliation and the recovery of imperial influence as a legitimate political objective.

In other words, Russia is not only a prisoner of geography. It is also a prisoner of its own historical narratives.

Indeed, the invasion of Ukraine in 2022 illustrates a weakness in overly geographical interpretations of international relations. If Russia's primary objective was to improve its security position, the invasion produced remarkably counterproductive consequences. Finland and Sweden abandoned their longstanding military non-alignment and joined NATO. Ukraine became more firmly oriented towards the West, while Russia acquired a substantially longer NATO frontier.

Geography helps explain why Russia might desire strategic depth. It does not explain why a particular leadership would choose a military strategy that substantially undermines that objective.

The distinction between geographical circumstances and political agency is therefore indispensable. Without it, geopolitical analysis risks becoming an exercise in explaining the inevitable after the event.

3. China: geography, ambition and the technological escape route

Marshall's discussion of China is another strong section. China faces a complicated geographical situation. Its eastern coastline provides access to international trade, but its maritime approaches are constrained by a series of island chains, strategic chokepoints and competing territorial claims.

The South China Sea, the Taiwan Strait and the approaches to the Indian Ocean are consequently central to Chinese strategic thinking. The Strait of Malacca is particularly important because a substantial portion of China's imported energy and international trade passes through this narrow maritime corridor.

Marshall also draws attention to China's continental vulnerabilities, including its extensive western and northern frontiers. The country must manage an enormous variety of geographical and political environments.

Yet China also demonstrates that geography is not an immutable prison.

Through massive infrastructure investments, China has transformed its transportation networks. High-speed railways, highways, ports, pipelines and ambitious international infrastructure projects have altered the practical significance of distance and accessibility.

The Belt and Road Initiative is particularly revealing. It can be interpreted partly as an attempt to overcome geographical vulnerabilities by creating alternative trade routes and expanding China's economic and strategic presence abroad.

But this raises a question Marshall's approach does not fully resolve: if geography imposes constraints, and technology and infrastructure can substantially modify those constraints, how do we determine the relative explanatory importance of the two?

Geography is not simply a fixed set of natural obstacles. Its political significance changes with technological development, economic organization and international cooperation.

The invention of container shipping, the construction of the Panama and Suez Canals, the development of aviation and the expansion of digital communications have all transformed the practical meaning of geographical distance.

The mountains have not disappeared, but the political and economic significance of mountains has changed.

China's experience suggests that geographical disadvantage can become a development challenge rather than a permanent destiny. It also demonstrates that governments can actively reshape their geographical circumstances, albeit at considerable financial and environmental cost.

4. The United States: the extraordinary advantages of location

Marshall is particularly persuasive when discussing the geographical advantages of the United States.

Protected by the Atlantic and Pacific Oceans, with relatively weak neighbours to the north and south, the United States enjoys a degree of continental security that few other major powers can match. Its extensive coastline, navigable river systems, fertile agricultural regions and access to two oceans have contributed enormously to its economic and military development.

The Mississippi-Missouri river system is an especially important asset. It connects vast agricultural and industrial regions through an extensive inland transportation network.

The United States also benefits from its geographical position between Europe and Asia. It can project power into both the Atlantic and Pacific regions without having to defend an exposed continental frontier against an equivalent rival.

These advantages help explain why the United States emerged as a global superpower.

But here, too, geography is only part of the story.

The country's rise also depended on political institutions, immigration, technological innovation, industrial development, financial organization, access to global markets and, not least, the outcome of two world wars that devastated much of its potential competition.

A map cannot explain why one society develops more productive institutions than another. Nor can it explain why some political systems encourage innovation while others suppress it.

The United States did not become powerful simply because it was located between two oceans. It became powerful because successive generations of Americans developed economic, political and military capacities that could exploit those geographical advantages.

Geography provided the stage and some of the props. It did not write the entire play.

5. Africa and the Middle East: geography is not the whole explanation

Marshall's treatment of Africa raises another important problem. He emphasizes the continent's enormous size, difficult transportation networks, fragmented river systems and the historical consequences of colonial boundary-making.

These are legitimate subjects. Africa's rivers are often less useful for inland transportation than those of Europe or North America because of waterfalls, rapids and other geographical obstacles. Its vast distances and uneven distribution of infrastructure have also complicated economic integration.

But the danger is that Africa becomes represented primarily as a continent of geographical disadvantages.

This overlooks the historical and political processes that have transformed those disadvantages into persistent developmental problems. Colonial exploitation, extractive economic structures, unequal international trade relations, political instability, authoritarian government and institutional weaknesses have all played major roles.

Geography does not explain why some African countries have developed more successfully than others despite sharing comparable geographical constraints.

Nor does it explain why colonial borders, which Marshall rightly emphasizes, have had such different consequences in different parts of the continent.

The Middle East provides an even more interesting example. Marshall's discussion of the Sykes-Picot Agreement, the artificial boundaries imposed by European colonial powers and the region's strategic energy resources is valuable.

However, the region's conflicts cannot be understood simply by looking at its borders, oil fields, deserts and transportation routes.

Religious movements, political ideologies, authoritarian regimes, competing nationalisms, foreign interventions and the internal struggles of individual societies all matter.

The geographical explanation of the Middle East can become particularly misleading when it encourages the impression that conflict is somehow natural to the region.

The region is not inherently condemned to instability. Its political history is the product of identifiable human decisions, institutions and power struggles.

Geography may help explain why particular territories are strategically contested. It cannot explain why political leaders choose particular methods of contestation, why some conflicts escalate while others are contained, or why peaceful political arrangements sometimes succeed.

6. The missing dimension: historical contingency and human agency

Perhaps the most important weakness of Marshall's approach is the relatively limited attention given to historical contingency.

Geographical features are comparatively stable, but political arrangements are not. The same geographical environment can accommodate radically different political systems, economic arrangements and international relationships.

Consider Western Europe.

Its geography has not fundamentally changed over the centuries, but its political history has been extraordinarily dynamic. It has experienced the rise and fall of empires, religious wars, revolutionary upheavals, nationalism, two world wars and, finally, an unprecedented experiment in political and economic integration.

The mountains and rivers remained. The political meaning attached to them changed.

The European Union is particularly instructive. Historically, Europe's geographical fragmentation contributed to the development of numerous competing states. Today, much of that same fragmentation has been overcome through political institutions, common markets, freedom of movement and supranational cooperation.

The Rhine, once an important strategic and commercial boundary, is now part of a highly integrated European economic space.

This is not an argument that geography has ceased to matter. It is an argument that institutions can transform the consequences of geographical circumstances.

There is another problem here: the tendency towards retrospective explanation.

Once a historical outcome has occurred, it is relatively easy to identify geographical characteristics that appear to have made it likely. Russia's western exposure explains its concern about invasion; Britain's island position explains its maritime orientation; China's coastline explains its maritime ambitions.

But how predictive are these observations?

Could geographical analysis have predicted the precise political trajectory of Russia after the collapse of the Soviet Union? Could it have predicted the European Union, the collapse of communism in Eastern Europe, or China's extraordinary economic transformation?

If geography is so powerful an explanatory variable, it should help us distinguish between different possible futures, rather than merely provide plausible explanations of past developments.

Marshall is much stronger at explaining why certain strategic concerns recur than at explaining why particular political outcomes occur.

That is a significant difference.

7. The technological challenge to geographical determinism

Another limitation is the relatively modest attention Marshall gives to technological change.

The physical world is not becoming flat, as some enthusiasts of globalization once suggested. But technology has profoundly altered the relationship between physical geography and political power.

Air power has reduced the military significance of many traditional geographical barriers. Satellite communications and digital networks have changed the meaning of distance. Modern transportation has transformed access to markets. Pipelines, canals, tunnels, bridges and undersea cables have created connections that would have been difficult to imagine in earlier centuries.

Even maritime geography is changing. The opening of Arctic shipping routes as sea ice diminishes could alter the strategic and commercial importance of northern waters.

Of course, technology does not abolish geography. It interacts with it.

A mountain range can still obstruct transportation, but modern tunnels can overcome some of its limitations. A landlocked country still faces disadvantages, but railways and international transport corridors can mitigate them. A country dependent on maritime imports remains vulnerable to blockades, but its options are not necessarily restricted to a single route.

The important point is that geographical constraints are historically variable in their practical significance.

A geographical feature is not automatically a geopolitical fact. It becomes one through the interaction of physical circumstances, technology, economic interests and political decisions.

This is a more sophisticated way of thinking about geopolitics than treating the map as an almost timeless explanation of national behaviour.

8. What Marshall leaves out: the political economy of power

There is a further omission worth emphasizing. Marshall's framework concentrates heavily on territorial security and the strategic calculations of nation-states.

But contemporary international power cannot be understood exclusively through territorial geography.

Financial networks, international trade, technological innovation, energy markets, global corporations, demographic change and institutional influence have become enormously important.

The United States, for example, derives much of its global power not simply from its geographical position but from the international role of the dollar, the strength of its financial institutions, its technological industries and its network of military alliances.

China's growing influence similarly depends on its industrial capacity, technological ambitions, trade relationships and financial investments.

These are not merely geographical phenomena, even when they have geographical consequences.

A country can possess excellent geographical advantages and nevertheless perform poorly because of institutional failures. Conversely, a country with substantial geographical disadvantages can prosper through effective governance, education, technological innovation and international cooperation.

A more complete geopolitical analysis would therefore combine physical geography with political economy, historical sociology and institutional analysis.

Marshall gives us an excellent introduction to the first. He is less successful at integrating the others.

9. A map is not an explanation

There is something inherently seductive about maps. They give complex realities an appearance of clarity and order. They allow us to see territorial relationships that are difficult to appreciate through textual descriptions alone.

Marshall understands this appeal and exploits it effectively.

But maps are selective representations of reality. They show certain relationships while concealing others. A political map displays national borders but not the institutional relationships that cross them. A physical map shows mountains and rivers but not the economic networks that transform their significance.

A map of Russia can show its enormous western exposure. It cannot show whether its leadership interprets that exposure defensively or imperialistically.

A map of the Middle East can display oil fields and contested boundaries. It cannot explain the political ideologies, religious movements and competing national projects that shape the region.

A map of Ukraine can illustrate its geographical position between Russia and Europe. It cannot establish that Ukraine belongs in anyone else's sphere of influence.

This last point is particularly important. Geopolitical explanations can easily slip into geopolitical prescriptions.

When we explain that a powerful country considers a neighbouring territory strategically indispensable, we should not confuse that country's strategic preference with a legitimate political entitlement.

Geographical proximity does not confer political ownership.

Douglas Webster's academic review of Marshall's book in the AAG Review of Books makes several related criticisms. He recognizes the importance of geographical factors but identifies weaknesses in the book's shifting explanatory approach, its limited thematic mapping and its insufficient engagement with technological and economic transformations. His assessment captures the central tension: Marshall's geographical insights are often persuasive, but his explanatory framework is less consistent than its confident presentation suggests.

10. The geopolitical worldview: useful realism or geographical fatalism?

Ultimately, Marshall's book belongs to a broader revival of geopolitical realism.

After the Cold War, there was considerable enthusiasm for the idea that economic globalization, liberal democracy and international institutions would gradually diminish the importance of territorial competition.

The return of great-power rivalry has challenged that optimism. Russia's invasion of Ukraine, China's growing military presence in the Indo-Pacific, American concerns about strategic competition and the renewed importance of energy security have all demonstrated that geographical considerations remain central to international politics.

In this respect, Marshall's book is a useful corrective to overly optimistic accounts of globalization.

However, geopolitical realism has its own blind spots. It can overemphasize the strategic calculations of great powers while underestimating the political agency of smaller countries and their populations.

Ukraine is again a revealing example. It is frequently discussed as a geographical buffer between Russia and the West, as though its principal significance lies in the strategic calculations of Moscow, Washington and Brussels.

But Ukraine is also a country with its own history, society, political divisions, national aspirations and democratic choices.

Its people are not geographical objects to be moved around on a strategic chessboard.

The same applies to Taiwan, the Baltic states, Poland and other countries situated in strategically sensitive locations.

A genuinely comprehensive geopolitics must account for the agency of smaller states, rather than treating them merely as pieces in the strategic games of larger ones.

This is where geographical realism needs a strong dose of political realism in the broader sense: an appreciation of power, but also of legitimacy, institutions, identity and human choice.

Conclusion: prisoners, perhaps, but not puppets

Tim Marshall has written an engaging and useful introduction to geopolitical thinking. His greatest achievement is to remind readers that the physical world has not disappeared beneath the abstractions of globalization. Mountains, rivers, oceans, plains, natural resources and strategic passages continue to influence the possibilities available to governments.

The book is particularly valuable for readers who want to understand why certain geopolitical concerns recur across generations. Russia's western exposure, China's maritime vulnerabilities, America's extraordinary geographical advantages and the strategic importance of the Middle East all become more intelligible through Marshall's geographical perspective.

But the book's central metaphor is also its principal limitation.

We are not simply prisoners of geography. We are inhabitants of geographical environments whose significance is constantly mediated by technology, economics, political institutions, historical experiences and human decisions.

Geography establishes constraints and opportunities. It does not dictate political intentions, moral responsibilities or historical outcomes.

There is also a danger in presenting geopolitical behaviour as though it were the inevitable expression of geographical necessity. Such an approach can normalize aggressive foreign policies, encourage great-power fatalism and obscure the choices available to political leaders.

Russia may have legitimate geographical security concerns. It does not follow that Ukraine must sacrifice its sovereignty to accommodate them. China may feel strategically constrained by its maritime surroundings. It does not follow that its neighbours must accept Chinese territorial claims. The United States may enjoy exceptional geographical advantages. It does not follow that American foreign policy is somehow predetermined or invariably benign.

A more appropriate metaphor might therefore be that geography is not a prison but a playing field: its physical boundaries matter, but the players, their strategies, their rules and their decisions determine what happens on it.

Marshall's book explains the playing field remarkably well. It is less convincing when it suggests that the field explains the game.

My verdict: Prisoners of Geography is an excellent popular introduction to the geographical foundations of geopolitics, but a less satisfactory general theory of international relations. Read it for its maps, its geographical insights and its historical illustrations. Read it critically when it moves from geographical constraints to political explanations.

The world is indeed shaped by geography. But it is not written by geography.

Appendix: Five questions Marshall's book should have addressed more thoroughly

1. How can geographical explanations be tested?

If geography explains political behaviour, what would count as evidence against a particular geographical explanation? Without clear criteria, geographical reasoning risks becoming retrospective storytelling.

2. How much can technology overcome geographical constraints?

The construction of canals, railways, pipelines, tunnels and digital networks demonstrates that geographical disadvantages are not necessarily permanent. How should these transformations be incorporated into geopolitical forecasting?

3. Why do countries with similar geographical circumstances develop differently?

Geography alone cannot explain the enormous differences in economic development, political stability and institutional quality between countries that face comparable environmental conditions.

4. When does geopolitical explanation become geopolitical justification?

Explaining why Russia wants strategic depth is not the same as justifying Russian expansionism. This distinction deserves much more attention.

5. Where are the smaller countries and their populations in the geopolitical picture?

A theory focused primarily on great powers risks turning smaller nations into passive geographical objects. Their political agency, sovereignty and historical aspirations must be part of the explanation.

The final question is perhaps the most important. Geography may shape the circumstances in which nations operate, but it does not deprive their inhabitants of political agency.
