The Silk Road: Connecting the ancient world through trade – Shannon Harris Castelo


A banker in London sends the latest stock info to his colleagues in Hong Kong in less than a second. With a single click, a customer in New York orders electronics made in Beijing, transported across the ocean within days by cargo plane or container ship. The speed and volume at which goods and information move across the world today is unprecedented in history. But global exchange itself is older than we think, reaching back over 2,000 years along a 5,000 mile stretch known as the Silk Road. The Silk Road wasn’t actually a single road, but a network of multiple routes that gradually emerged over centuries, connecting to various settlements and to each other thread by thread. The first agricultural civilizations were isolated places in fertile river valleys, their travel impeded by surrounding geography and fear of the unknown. But as they grew, they found that the arid deserts and steps on their borders were inhabited, not by the demons of folklore, but nomadic tribes on horseback. The Scythians, who ranged from Hungary to Mongolia, had come in contact with the civilizations of Greece, Egypt, India and China. These encounters were often less than peaceful. But even through raids and warfare, as well as trade and protection of traveling merchants in exchange for tariffs, the nomads began to spread goods, ideas and technologies between cultures with no direct contact. One of the most important strands of this growing web was the Persian Royal Road, completed by Darius the First in the 5th century BCE. Stretching nearly 2,000 miles from the Tigris River to the Aegean Sea, its regular relay points allowed goods and messages to travel at nearly 1/10 the time it would take a single traveler. With Alexander the Great’s conquest of Persia, and expansion into Central Asia through capturing cities like Samarkand, and establishing new ones like Alexandria Eschate, the network of Greek, Egyptian, Persian and Indian culture and trade extended farther east than ever before, laying the foundations for a bridge between China and the West. This was realized in the 2nd century BCE, when an ambassador named Zhang Qian, sent to negotiate with nomads in the West, returned to the Han Emperor with tales of sophisticated civilizations, prosperous trade and exotic goods beyond the western borders. Ambassadors and merchants were sent towards Persia and India to trade silk and jade for horses and cotton, along with armies to secure their passage. Eastern and western routes gradually linked together into an integrated system spanning Eurasia, enabling cultural and commercial exhange farther than ever before. Chinese goods made their way to Rome, causing an outflow of gold that led to a ban on silk, while Roman glassware was highly prized in China. Military expeditions in Central Asia also saw encounters between Chinese and Roman soldiers. Possibly even transmitting crossbow technology to the Western world. Demand for exotic and foreign goods and the profits they brought, kept the strands of the Silk Road in tact, even as the Roman Empire disintegrated and Chinese dynasties rose and fell. Even Mongolian hoards, known for pillage and plunder, actively protected the trade routes, rather than disrupting them. But along with commodities, these routes also enabled the movement of traditions, innovations, ideologies and languages. Originating in India, Buddhism migrated to China and Japan to become the dominant religion there. Islam spread from the Arabian Penninsula into South Asia, blending with native beliefs and leading to new faiths, like Sikhism. And gunpowder made its way from China to the Middle East forging the futures of the Ottoman, Safavid and Mughul Empires. In a way, the Silk Road’s success led to its own demise as new maritime technologies, like the magnetic compass, found their way to Europe, making long land routes obsolete. Meanwhile, the collapse of Mongol rule was followed by China’s withdrawal from international trade. But even though the old routes and networks did not last, they had changed the world forever and there was no going back. Europeans seeking new maritime routes to the riches they knew awaited in East Asia led to the Age of Exploration and expansion into Africa and the Americas. Today, global interconnectedness shapes our lives like never before. Canadian shoppers buy t-shirts made in Bangladesh, Japanese audiences watch British television shows, and Tunisians use American software to launch a revolution. The impact of globalization on culture and economy is indisputable. But whatever its benefits and drawbacks, it is far from a new phenomenon. And though the mountains, deserts and oceans that once separated us are now circumvented through super sonic vehicles, cross-continental communication cables, and signals beamed through space rather than caravans traveling for months, none of it would have been possible without the pioneering cultures whose efforts created the Silk Road: history’s first world wide web.

  1. Do not forget that at least the main reason for the fall of the silk road is the appearance of the Ottoman Empire, which dominated the sea and did not allow Europeans to trade, and through Russia it was dangerous to trade because of wars and poorly developed roads

  2. I feel this understates the impact it had on Europe. This is probably the birth of international trade that we know today.

  3. what rubbish, the royal road laid the foundation of the silk road? yet another attempt to belittle the Chinese who were by far the driving force of the silk road, hence the name!

  4. the west has gone really sino centric these days, otherwise why did columbus not name native americans as red chinese instead of red indians if he was looking for route to ''east asia''.

  5. Amazing! I love your videos! I already liked this video and already subscribed. I'm your biggest fan!!! Keep up the good work guys!!!

  6. This video didn't mention the fact that the Ottoman Empire blocked trade access to Asia which was an important factor in the age of exploration.

  7. Sikhism isn't a result of Islamic ideas. C'mon! you know better Ted-Ed. In fact, Sikhs fought many wars with the Muslims. They are arch-enemies. Hinduism gave birth to Sikhism.

  8. You should do a episode on transoceanic trade in the bronze age after all how does the extract of a plant found only in the Americas end up in New Kingdom mummy in Egypt?

  9. Since the time I had read about the silk route in Social Studies, I had this dream of traveling on it, like literally covering its all the stops and going from one end to another, now it seems like a web, its going to be a bit difficult 🤓

  11. For a short video I can understand why many things were not mentioned but to say that the silk road originated in Europe is totally wrong. I would have at least mentioned the drug trade and the spread of disease. Even though it is full of questions, it gets the point across so I'll use it in my class.

  12. @5:00 The area with the most intricate roads right in the upper middle part with no title. That's Turkestan, the lands of Turkic people.
    Western historians tend to ignore it, but just as highest forms of wisdom came out of there once, it might just happen again in the future.

  13. It is amazing how China, Persia, India an the Roman Empire traded goods and exchanged knowledge, books, arts and religion along the Silk Road.

  14. Emperor Xi approves this..now lets give out more loans to impoverished Asian countries, building infrastructure they never needed

  15. i like how useful this is in life. infact, im studying to become an ancient chinese silk trader right now. such a wonderful skill to have, i think everyone should train to be an ancient chinese silk trader, such a shame the industry has gone out of business

  16. The idea of Closed China during Ming Dysnasty is false. They still maintained international trade but via private businessmen as national controlled trade proved inefficient.

    Just because Ming didn't send out more expedition fleets doesn't mean they didn't realize how lucrative the trade with regions explored were.

  17. To anyone who has money and wants to launder this money we can buy you real estate and stock from the stock exchange in Kuwait only You have to transfer the money from your account to our account in Kuwait Information Watts 0096599706407

  18. Hi TED-Ed.
    I really enjoy your videos and I'm grateful for them, for their content and all the hard work that goes into them.
    So it's with the greatest respect that I feel I must point out that your remark about Islam's spread to South Asia, where it "blended with native beliefs and led to new faiths like Sikhism" is wholly misleading.
    As a practising Sikh it would be remiss of me not to state that this common idea of Sikhism being a mish-mash of Hindu and Muslim traditions is a fallacy, not to mention a little insulting, since it denies Sikhs their own authentic identity and agency as devotees of a religion that is its own.
    I know it wasn't deliberate, I'm not offended… you teach me stuff all the time, I hope I've been able to return the favour.
    Thank you and keep up the excellent work.

  19. Tennesseans used american software to launch a revolution? Why not mention the armericans who used middle eastern oil to launch wars?!
