How Trade Has Shaped Societies: War, Peace, and Power
This paper examines how trade has shaped societies over approximately 2,000 years, arguing that trade functions as a double-edged sword capable of promoting peace and prosperity while simultaneously motivating conflict and war. Drawing on examples ranging from the Silk Road and the Pax Romana to the Mongol-facilitated Renaissance, colonial expansion, and modern U.S.–China trade relations, the paper traces how the control of trade routes, resources, and ideologies has repeatedly determined whether nations cooperate or clash. The paper concludes that trade tends to produce peace when mutual benefit is recognized, but generates conflict when competition and zero-sum thinking take hold among states.

What makes this paper effective
- The paper uses a clear, sustained central metaphor — trade as a "double-edged sword" — that frames every historical example and gives the argument structural coherence from introduction to conclusion.
- It covers an impressive chronological sweep (from the second century BC to the 21st century), connecting disparate events through a single analytical thread about the relationship between trade, power, and conflict.
- Concrete, specific examples (Buddhism spreading via the Silk Road, tomatoes arriving in Italy, Nixon opening China) ground abstract claims about trade in recognizable historical events.
Key academic technique demonstrated
The paper demonstrates the use of comparative historical analysis: it places geographically and temporally distant events side by side (Pax Romana and Pax Mongolica; Silk Road and Nixon's China policy) to reveal a recurring pattern. This technique allows the author to support a broad thesis about trade and society without reducing the argument to a single case study.
Structure breakdown
The paper opens with a thesis statement introducing the double-edged-sword framework, then proceeds largely chronologically through historical examples. Each body paragraph develops a specific episode and connects it back to the central argument. The conclusion synthesizes the two outcomes — trade promoting peace vs. trade triggering war — and applies them to contemporary geopolitics, bringing the argument full circle.
Introduction: Trade as a Double-Edged Sword
Trade has tended to bring about peace more often than not. However, to control trade, nations have been willing to go to war. Thus, trade can be seen as a double-edged sword — one that cuts both ways throughout history, from the time of the Silk Road to the present. Trade can cut one way towards peace, yet the fact that it can be so lucrative — and that control of trade routes means control over a great many nations — has also meant that trade can lead to war when one nation feels it is in its own best interests to assert itself. This paper shows how trade has affected societies for 2,000 years by serving as the motivation for both peace and war.
The Silk Road, the Pax Romana, and the Spread of Ideas
The Silk Road was an ancient trade network between the East and the West that existed from approximately the second century BC to the 15th century AD. Silk was a commodity that the East offered in abundance and that was much desired in the West. While war and peace can be seen throughout all those centuries in which the Silk Road persisted, one fact never changed: trade helped to develop nations. Commodities such as silk and spices were not the only things to change hands; ideas, religions, and technology did as well. Trade allowed different peoples from different societies to connect, share information and goods, and learn from one another. In many cases, trade promoted and fostered peace because so many stakeholders had an interest in stability, given the benefits that peace could bring to commerce.
One of the first instances of this is the Pax Romana that the Roman Empire implemented in the first century AD (Khan Academy). It lasted for nearly 200 years, and during that time there were very few wars. What the Han dynasty in China understood was the same thing Rome saw: peace bred stability, which bred prosperity through trade. As Adam Smith would explain several centuries later, nations that excel at producing certain goods will naturally find it in everyone's best interests to maintain good relations with other nations so that they can trade what they produce efficiently for what others produce just as well.
Buddhism, which originated in India, spread to China thanks to the Silk Road. Today, Buddhism is often associated with China, even though that is not where it originated. This is but one example of how nations become well known for something that did not even originate with them. Tomato sauce coming from Italy is another example — tomatoes are not native to Italy but were brought there through trade with the Americas. One could thus argue that a defining element of Italian cuisine actually came from the Americas, something that would not occur until after 1492, when Columbus sailed west to find the Indies and accidentally discovered the Americas.
Control of Trade Routes in the Middle Ages
Controlling not only the Silk Road through the Middle East but also the resources so valuable to trade became an important issue throughout the Middle Ages. The rise of Islam brought about various wars as groups sought to close or open different trade routes. When Byzantium learned how the silkworm produces its silk, the monopoly on silk that China had long enjoyed came to an end. China was no longer able to control that resource, and dependence upon it as a trade partner came to a momentary halt.
The control of resources has always been a factor in how trade impacts the world. When one part of the world controls important resources — such as oil, gas, or rare earth metals — it makes other parts of the world dependent upon it, and that dependence can lead to war, especially when those other parts of the world are unwilling to accept a subordinate posture. World War I and World War II were in no small part about securing access to the Middle East. The British Empire worked to undermine the Ottoman Empire and its alliance with Germany, allying with the House of Saud against the Ottomans. World War II saw a rejuvenated Germany imposing its will in ways that made England, France, and Soviet Russia deeply uncomfortable. A strong Germany would always threaten England's trade dominance.
Conclusion
Trade tends to affect nations in one of two ways: it promotes peace, or it leads to war. It promotes peace when nations recognize that they both stand to benefit from a win-win environment in which all parties share in the exchange of goods and ideas. It is when a sense of competition emerges among states that trade begins to beat the drumbeats of war. Controlling trade routes and trading posts has been a source of conflict throughout the Middle Ages — following the rise of Islam in the Middle East and prior to the Mongol conquest — and it is becoming a source of tension again today, as the US engages in a zero-sum contest with other world powers. Control of the sea lanes and the New Silk Road that China aims to reopen lies at the heart of the tension between East and West today.
