Introduction

Geography plays an important part in the safety of a civilization. Many nations possess natural boundaries that protect them from foreign invasion, like the Himalayas for India and the Gobi Desert for China. But the choke points, also called bottlenecks, are far more important aspects of geography compared to mountains and deserts when it comes to defence, conquests, and power projections. Choke points can allow numerically weaker forces to defeat comparatively larger ones or at least give them the ability to cause significant damage. They can also allow a superior strategic force to dominate an area for years, decades, centuries, or even millennia. This blog lists 8 such important choke points, arranged from west to east, that played an important role in changing history, maintaining power, the fall of civilizations, and the emergence of new powers.

Chapter 1 – The Strait of Gibraltar

The Strait of Gibraltar connects the Atlantic Ocean to the Mediterranean Sea and separates the continents of Africa and Europe. The Strait lies in the territorial waters of Spain, Morocco, and the British Overseas Territory of Gibraltar. This passage was historically under the control of the Carthaginians, the Romans, and later European Colonial Empires. The Carthaginians and the Romans used this strait to dominate the Mediterranean and the naval trade routes. During the Age of Exploration, it was used by the Spanish, the Portuguese, and later the British to dictate their colonial supremacy. Its significance continues in modern times, as used by the European Union and Western European countries for conducting trade and commerce with America and Western Africa.

Chapter 2 – The English Channel

The English Channel is the narrow arm of the Atlantic Ocean that separates France and the United Kingdom. In its easternmost side, it links with the North Sea via the Strait of Dover. It has always been a natural defence for England from continental Europe and protected England from invasions from Julius Caesar and Napoleon Bonaparte, to Nazi Germany in World War II. The channel also helped the British economy, enabling the United Kingdom to become the British Empire in the 18th to 20th centuries. This channel is still the busiest shipping area of the world, which is used by the British Isles to trade with the rest of the world.

Chapter 3 – Bosphorus and Dardanelles Straits

The Straits of Bosphorus and Dardanelles connect the Black Sea with the Mediterranean Sea via the Sea of Marmara, thus separating Asia from Europe. This region is of great historical significance. From the Trojan War to the conquests by Alexander the Great, to the emergence of the Byzantine and Ottoman Empires as superpowers of the world, these straits have always played important roles. Even in the last century, in World War I, the Dardanelles Campaign highlighted their continued strategic significance even at the age of metal warships and missiles. Presently, the nation of Turkiye controls the strait, thus possessing significant power in the Southeastern European region.

Chapter 4 – Bab-el-Mandeb

The Bab-el-Mandeb is the strait between Yemen in the Arabian Peninsula and the nations of Djibouti and Eritrea in the Horn of Africa, connecting the Red Sea to the Gulf of Aden and, in turn, the Indian Ocean. Literally meaning the Gates of Lamentation, Bab-el-Mandeb derives its name from the dangers of navigating through it. In spite of this, the strait acted as an important route for trade between Egypt, Arabia, and India, and after the construction of the Suez Canal, the route became significantly important to the Europeans for trading with India and Southeast Asia. Even today, this strait acts as an important route for commerce between Mediterranean countries and the countries bordering the Indian Ocean.

Chapter 5 – The Strait of Hormuz

This is a strait between the Persian Gulf and the Gulf of Oman and historically acted as the gateway to the Persian World. The strait was used by the Achaemenids, the Sassanians, and the Arab Caliphates to trade with East Africa, India, Southeast Asia, and even China. In the later medieval period, the Arabian and Persian traders used to trade with Venetian merchants through the Strait and the Strait of Bab-el-Mandeb. For the last two centuries, the world’s superpowers have fought to gain control of this strait for the high production of oil in the Gulf Countries. As of 2023, about 25% of seaborne oil and 20% of liquified natural gases trade passes through this strait.

Chapter 6 – The Khyber Pass

The Khyber Pass is a mountain pass in the Khyber-Pakhtunkhwa province of Pakistan. It acts as the gateway to the Indian Subcontinent from Central Asia. Invading forces like the Persians, Greeks under Alexander, Huns, Turks like Mahmud of Ghazni, and Mohammad Ghori, and finally the Mughal army, entered India through this pass. As it was part of the Silk Route, it connected India with the regions of China, Persia, Greece, and even Egypt. So this region has played an important role in constructing the history of the subcontinent through cultural, economic, and political ways. It is still considered one of the most famous mountain passes in the world.

Chapter 7 – The Tarim Basin

The Tarim Basin is a basin formed by the Tarim River in the Uyghur province of Xinjiang in China. It is a mountainous region with ranges like the Kunlun and the Tian Shan with many passes, and it was traditionally used by the Chinese, Mongols, and Tibetans to conduct business with the West for millennia. Empires like the Han, Tang, and later the Mongols controlled the Silk Route trades by controlling the Tarim Basin Area. What the Khyber Pass is to the Indian Subcontinent, the Tarim Basin is the same for the Sinosphere. Both regions are open to Central Asia through these passes, which have resulted in the trade of technology, culture, and religion.

Chapter 8 – The Straits of Malacca and Sunda

The Strait of Malacca is a strait that connects the Andaman Sea and the South China Sea. It separates the Malay Peninsula from the Indonesian island of Sumatra. The Strait of Sunda, on the other hand, lies between the Indonesian islands of Sumatra and Java, connecting the Indian Ocean to the Java Sea. Historically, both straits have acted as the naval link between China and India, with Southeast Asia. The Southeast Asian empires of Srivijaya, Majapahit, and the Indian Chola Empire governed and ruled this region alternatively. Later, these straits were used by the Portuguese, the Dutch, and the British to colonize regions of Southeast Asia. Besides empires, these regions also bred pirates who looted ships passing through these regions. Presently, the Strait of Malacca is considered the most important choke point in the world as it connects the Pacific Ocean with the Indian Ocean, resulting in trade and business between the Americas, Asia, and East Africa.

Conclusion

Choke Points are naturally (mostly) occurring, important regions of the world that have decided the fate of empires, nations, and civilizations through culture, wisdom, economy, polity, and power. The straits and passes were very crucial for both trade and invasions in ancient, medieval, and early modern times. Even today, Straits like Malacca and the Bosphorus are considered to be some of the most important geographical features of the modern world, which decide the economy and political influence in certain regions. That’s all for this blog. This blog has been intentionally kept short after three longer blogs. I know I have not added important choke points like the Bering Strait, the Cape of Good Hope, the Panama Canal, and the Suez Canal. Wanted the blog to be short, so only included the most important ones historically, culturally, and geopolitically.
