## Slide Transcript

### Slide 1: The Silk Road

- Caravans across Eurasia
- ~ 200 BC · 1450 AD
- A history in thirteen panels

### Slide 2: I. Origins — A Han Envoy Heads West

- In 138 BC, Emperor Wu of the Han dispatched the diplomat Zhang Qian to find allies against the Xiongnu. He was captured for a decade, escaped, and returned with reports of vast civilizations beyond the Pamirs — Bactria, Parthia, Ferghana.
- His mission opened formal Chinese contact with Central Asia. By the 1st century AD, Han silks were reaching Rome, where senators lamented the bullion drain — Pliny the Elder estimated 100 million sesterces a year flowing east.
- "He saw cities walled with brick, and grapes that became wine." — paraphrased from the Shiji

### Slide 3: II. Not One Road — A Network

- "The Silk Road" is a 19th-century coinage (Ferdinand von Richthofen, 1877). On the ground it was a braided web of caravan tracks, mountain passes, and oasis cities — chosen each year by water, weather, and warlords.
- From the Levant to Chang'an, ~6,400 km — but few traders ever traveled the whole way.

### Slide 4: III. The Traders

- Goods passed through dozens of hands. The road belonged to many peoples; none of them were called "Silk Road merchants."
- Sogdians
- Iranian-speaking traders from Samarkand & Bukhara. Their language was the lingua franca of the road for centuries.
- Bactrians & Persians
- Caravan organizers, animal breeders, money-changers — masters of the central corridors.
- Arabs
- After the 7th century, dominant from Damascus to the Indian Ocean rim — and across Saharan offshoots.
- Radhanite Jews
- Multilingual merchants who linked Christendom, Islam, and India — recorded by Ibn Khordadbeh, c. 870.
- Chinese
- Silk producers, monks (Xuanzang), and from Tang times resident merchants in oasis cities.
- Indians, Tibetans, Uyghurs
- Buddhist networks, mountain pass-keepers, steppe middlemen — all with their share of the staffing.

### Slide 5: IV. Goods, Both Ways

- Westbound from China
- Silk — light, valuable, almost a currency
- Porcelain & lacquerware
- Tea (later), rhubarb, cinnamon
- Paper & (much later) gunpowder
- Eastbound to China
- Ferghana horses — "heavenly" warhorses
- Roman & Sasanian glass
- Gold, silver, gems, ivory, coral
- Spices, frankincense, woolen carpets
- Grapes, alfalfa, cucumbers, walnuts
- Most goods changed hands many times; prices multiplied tenfold or more by journey's end.

### Slide 6: V. The Bigger Trade — Ideas

- If silk paid the carriers, ideas reshaped the civilizations they passed through.
- Buddhism walked east with monks and merchants — by the 4th c. AD, cave monasteries from Bamiyan to Dunhuang.
- Paper moved west: Chinese craftsmen captured at Talas (751) brought the technique to Samarkand, then Baghdad, then Europe.
- Mathematics: Indian numerals, Persian algebra (al-Khwarizmi), Chinese magic squares — all crossed the road.
- Religions: Manichaeism, Nestorian Christianity, Zoroastrianism, and later Islam all rode the caravans into China.
- Technologies: stirrups, the compass, sericulture (smuggled west by Byzantine monks, c. 552), printing.
- "What truly traveled the Silk Road was not goods, but knowledge in the saddlebags between them."

### Slide 7: VI. The Tang Apogee (618 – 907)

- Under the Tang, Chang'an was the largest, most cosmopolitan city on Earth — perhaps one million residents inside its walls, with dedicated quarters for Sogdian, Persian, Arab, and Indian merchants.
- The Tang state actively patrolled the routes. Garrisons in the Tarim oases kept caravans safe. Persian refugees from Sasanid Iran (post-651) settled at the imperial court.
- In 751, Tang armies met the Abbasids at Talas. The defeat ended Chinese westward expansion — but seeded paper-making across Islam.

### Slide 8: VII. The Mongol Pax (1206 – 1368)

- Under Genghis Khan and his heirs, a single political order stretched from the Yellow Sea to the Black Sea. For the first time, a merchant could in principle travel coast-to-coast under one law and one passport (the paiza).
- The Yam — a state postal relay system, ~1,400 stations, fresh horses every 40 km.
- Tolerance of religions; cosmopolitan courts at Karakorum, Khanbaliq (Beijing), Tabriz.
- Marco Polo (1271 – 1295) reached Kublai's court and went home with stories Europe could barely believe.
- Ibn Battuta, William of Rubruck, Rabban Bar Sauma — the road's golden generation of travel writers.
- "A maiden bearing a nugget of gold could walk alone from one end of the empire to the other." — attributed legend

### Slide 9: VIII. The Plague Rides West (~1346)

- The same routes that moved silk and silver moved Yersinia pestis. Outbreaks in Inner Asia in the 1330s spread along caravan tracks to the Crimea — and from there into the holds of Genoese ships.
- Within a decade, the Black Death killed perhaps a third of Europe and a comparable share of Western Asia. The Mongol order, already fraying, lost its grip on the central corridor.
- "The road of riches was also the road of pestilence."
- ~ 75M –200M
- estimated dead, 14th c. pandemic

### Slide 10: IX. The Maritime Silk Road

- Long before "the" Silk Road declined, a parallel sea route was already humming — monsoon-driven Indian Ocean traffic between the Red Sea, East Africa, India, Southeast Asia, and southern China.
- Roman traders sailed to Muziris (Kerala) by the 1st c. AD; Chinese ports like Guangzhou and Quanzhou hosted Persian and Arab quarters.
- By the 13th c., Chinese junks of 1,000 tons crossed routinely to Hormuz.
- Zheng He (1405 – 1433) led seven Ming treasure fleets — up to 300 ships, 28,000 men — as far as Mogadishu and the Swahili coast.
- Then, abruptly, the Ming turned inward: shipyards burned, voyages ended.
- The ocean would soon belong to others.

### Slide 11: X. Decline of the Overland Routes

- The 15th century delivered a triple blow:
- The breakup of the Mongol khanates raised tolls and risk.
- The Ottoman conquest of Constantinople (1453) tightened the Levant choke-point.
- Portuguese caravels rounded Africa (Vasco da Gama, 1498) — bypassing the middlemen entirely.
- Spices that had cost a fortune in Venice could now be loaded directly in Calicut. The economic logic of the caravan collapsed.

### Slide 12: XI. Modern Echoes

- The routes never truly closed. Caravans dwindled but did not vanish; the cities along them — Samarkand, Bukhara, Kashgar, Xi'an — kept their bones.
- 19th c. — the "Great Game" maps the same passes Zhang Qian once crossed.
- 1877 — Richthofen invents the phrase Seidenstraße.
- 2013 — China announces the Belt and Road Initiative: rail, ports, fiber following the old corridors.
- Today — freight trains run Yiwu → Madrid in ~18 days; data cables thread the Caspian floor.
- "Geography is patient. The same valleys that suited a camel's hoof tend to suit a railway grade."
