Strait of Hormuz
The World's Most Important Oil Chokepoint
The narrow passage between Iran and the Arabian Peninsula through which one-fifth of global oil supply transits daily. Control of Hormuz means leverage over the world economy.
The Geopolitical Encyclopedia
Borders are arguments
made visible.
Every alliance, every conflict, every trade route follows a logic older than the states themselves. We map that logic — from Mackinder to Malacca, from Westphalia to the present hour.
Foundational Concepts
Core theories and frameworks essential for understanding geopolitics.
Strait of Malacca
Asia's Lifeline and Strategic Vulnerability
The narrow waterway between Malaysia and Indonesia through which nearly one-third of global maritime trade passes. For rising Asian powers, Malacca is both lifeline and potential stranglehold.
Balance of Power
The Oldest Principle of International Relations
The theory that peace and stability emerge when no single state dominates the system. For centuries, the balance of power has shaped alliances, wars, and the fundamental structure of world order.
Containment
The Grand Strategy of the Cold War
The American strategy of preventing Soviet expansion through a combination of military alliances, economic aid, and political pressure. Containment defined four decades of global competition.
What Is Geopolitics?
The Study of Power and Geography
An introduction to geopolitics—the study of how geography shapes international relations. Understanding geopolitical concepts provides a framework for making sense of world events.
Heartland Theory
Mackinder's Geographical Pivot of History
The foundational geopolitical theory arguing that control of Central Eurasia—the 'Heartland'—is the key to world domination. Mackinder's 1904 thesis reshaped how nations think about geography and power.
Rimland Theory
Spykman's Challenge to the Heartland
Nicholas Spykman's counterargument to Mackinder, proposing that the Eurasian coastal regions—not the interior—hold the key to world power. This theory directly shaped American Cold War strategy.
Sea Power
Command of the Oceans and Global Influence
The theory that control of the seas is the foundation of national greatness. From Alfred Thayer Mahan to modern naval strategy, sea power has shaped the rise and fall of empires.
China
The Re-Emerging Superpower
The world's most populous nation and second-largest economy is reshaping the international order. Understanding China's geography, history, and strategic culture is essential for comprehending 21st-century geopolitics.
Russia
The Eternal Heartland Power
The world's largest country by territory, nuclear superpower, and heir to a thousand years of expansion and contraction. Russia's geography shapes a strategic culture of insecurity, defensiveness, and periodic aggression.
United States
The Offshore Hegemon
The world's sole superpower, protected by two oceans and blessed with unmatched resources. American power has shaped the international order since 1945—but faces growing challenges from rising competitors.
Alfred Thayer Mahan
Prophet of Sea Power
The American naval officer whose theories of sea power transformed global strategy. Mahan's ideas drove naval buildups from the United States to Japan and remain foundational to maritime strategic thinking.
Halford Mackinder
Father of Geopolitics
The British geographer who invented geopolitical analysis. Mackinder's Heartland Theory and vision of geography as the 'handmaid of statecraft' founded the field and shaped a century of strategic thinking.
Essential Reading
Suez Canal
The artificial waterway connecting the Mediterranean to the Red Sea, eliminating the need to sail around Africa. Control of Suez has triggered wars and remains vital to European-Asian commerce.
Deterrence Theory
Deterrence theory explains how states prevent adversaries from taking unwanted actions by maintaining credible threats of punishment—a logic that underpins nuclear strategy and extends to conventional, cyber, and economic domains.
Digital Sovereignty
Digital sovereignty refers to a nation's capacity to govern the digital infrastructure, data flows, and technological systems operating within its borders—an increasingly contested domain as power in the twenty-first century flows through fiber optic cables as much as oil pipelines.
Geoeconomics
Geoeconomics describes the practice of wielding economic instruments—trade, investment, sanctions, technology controls—to achieve strategic objectives that were once pursued primarily through military means.
Globalization
Globalization describes the intensification of cross-border flows of goods, capital, people, and ideas that has reshaped the world economy and international politics—a process now facing unprecedented challenges from geopolitical rivalry, technological change, and domestic backlash.
Gray Zone Conflict
Gray zone conflict describes activities that fall between routine statecraft and open warfare—coercive actions that challenge adversaries while remaining ambiguous enough to avoid triggering decisive military response.
Hybrid Warfare
Hybrid warfare combines conventional military operations with cyber attacks, information warfare, economic coercion, and proxy forces to achieve strategic objectives while avoiding the costs and risks of traditional armed conflict.
Multipolarity
A multipolar world is one in which power is distributed among several major states, none of which can dominate the others—a configuration that may bring both greater regional autonomy and heightened risks of great power conflict.
Nationalism
Nationalism holds that the nation—a community defined by shared culture, history, language, or identity—should be the primary unit of political organization and the supreme object of loyalty, a force that has both unified peoples and divided continents.
Neoliberalism
Neoliberalism describes an economic and political framework that emphasizes free markets, deregulation, privatization, and reduced state intervention—an ideology that has shaped global economic policy since the 1980s and generated intense debate about its benefits and costs.
Strategic Autonomy
Strategic autonomy refers to a state's ability to make and implement decisions in defense, foreign policy, and critical technologies without excessive dependence on external powers—a concept that has gained urgency as great power competition intensifies.
Weaponized Interdependence
Weaponized interdependence describes how states exploit their central positions in global economic and technological networks to coerce others—turning the infrastructure of globalization into instruments of power.
The logic beneath the news
In 1904, a British geographer stood before the Royal Geographical Society and argued that whoever controlled the interior of Eurasia would command the world. A century later, NATO expansion, China's Belt and Road, and Russia's wars still trace the lines he drew.
This is not coincidence. It is geography.
Mountains dictate where armies stop. Straits determine which economies breathe. The distance between a capital and its coastline shapes whether a nation looks inward or outward, trades or fortifies, rises or fractures. These forces do not trend. They do not cycle. They persist.
