The Silk Road map: a network, not a line
Open a Silk Road map and you will see many lines, not one. That is accurate. The Silk Road was a historical trade network made of different routes. It linked China to Europe through Anatolia and the Mediterranean.
The name is also younger than the trade. The German geographer Ferdinand von Richthofen popularised the German word Seidenstraße in 1877.
UNESCO says people adapted the use of these routes to changing economic and political conditions. That use continued until the 19th century. So when you picture the Silk Road, picture a web that shifted over the centuries.
Where did the Silk Road start and end?
The honest answer is that it had many starts and many ends. Still, you can follow one thread from east to west.
In China, UNESCO describes a corridor of about 5,000 kilometres. It runs from the cities of Chang’an and Luoyang to the Zhetysu region of Central Asia. It took shape between the 2nd century BCE and the 1st century CE.
Further west, two routes followed the northern and southern edges of the Taklamakan Desert. They joined again at Kashgar.
In Central Asia, UNESCO lists the 866-kilometre Zarafshan-Karakum Corridor. It follows the Zarafshan River west, then crosses the Karakum Desert to the Merv Oasis.
How did trade actually work?
Here is the key idea. Goods moved in relays.
UNESCO says caravans often covered only certain sections of the road. They sold their loads at intermediate markets to other traders. A bolt of silk did not usually travel with one owner from China to the Mediterranean.
You already know this system. Think about the last thing you bought in a shop. It probably passed through a wholesaler and a distributor before it reached the shelf. Silk Road goods changed hands in a similar way, just much more slowly.
On land in the Middle Ages, horse and camel caravans carried the goods. Silk was the famous cargo. But UNESCO also lists spices, grain, animal skins, metalwork and precious stones moving between China and the Mediterranean.
Caravanserais: the motels of the road
A caravan needed places to stop. That is what caravanserais were for.
On well-served stretches of the Silk Road, caravanserais stood about 30 to 40 kilometres apart. That distance matched roughly one day of travel. A trader could plan a journey as a chain of overnight stops.
In Anatolia, the Seljuks built hans and caravanserais along the routes. The Ministry of Culture and Tourism says they did this to keep trade alive and to make the roads safe.
The merchants: Sogdians on the road
Who were the traders? One famous group came from around Samarkand. These were the Sogdians. They were important players in Silk Road trade between the 4th and 9th centuries CE.
We know a surprising amount about them from their own mail. We cover that in the section on details you won’t find in guidebooks.
How did silk reach Istanbul?
By the 6th century CE, silk production knowledge itself had reached Byzantium.
Medieval Byzantine silk clothing production was subject to detailed regulation. Silk was also one of the important sources of state revenue. So the Silk Road shaped the economy of the empire whose capital became Istanbul.
Silk Road routes through Turkey
If you travel in Turkey, you can follow the Silk Road on today’s map. The Ministry of Culture and Tourism lists several Anatolian routes.
- An Istanbul route: Erzurum, Malatya, Kayseri, Ankara, Bilecik, Bursa, Iznik, Izmit and Istanbul.
- The northern route: Trabzon, Gumushane, Erzurum, Sivas, Tokat, Amasya, Kastamonu, Adapazari and Izmit, reaching Istanbul and Edirne.
- The southern route: Mardin, Diyarbakir, Adiyaman, Malatya, Kahramanmaras, Kayseri, Nevsehir, Aksaray, Konya, Isparta and Denizli, reaching Antalya.
Several of these places were ports or gateways. Trabzon and Sinop opened to the Black Sea. Alanya and Antalya opened to the Mediterranean. Goods could leave the overland network and continue by sea.
Bursa is a good stop for you if you like trade history. Its Hanlar District became the economic centre of the city from the 14th century.

Safe passage: the Mongol postal roads
States also built the infrastructure. On the postal roads of the Mongol Empire, envoys carried paiza tablets. The Rubin Museum says a tablet gave its bearer the right to ask stations for lodging, food, fresh horses and an escort.
That is a travel pass backed by state power. It shows that the long-distance system depended on more than merchants.
Religion and ideas travelled too
Goods were not the only cargo. UNESCO describes Buddhist cave temples stretching from Luoyang west to Kucha. They preserve traces of Buddhism spreading east from India via Karakorum.
So the same road that carried silk also carried belief. The network moved production knowledge, religion and cultural practices as well as goods.
Details you won’t find in guidebooks
A merchant’s mail survives. In 1907, Aurel Stein found five nearly complete Sogdian letters in a Chinese watchtower. It stood about 90 kilometres west of Dunhuang.
One letter is about money. Sogdian Letter 2 is business correspondence. A merchant in China wrote to Samarkand about distributing money left on deposit there.
The letters name real goods. They mention Tibetan musk, pepper, silver and linen.
The amounts were small. The quantities in the letters suggest fairly small-scale trade. It focused on goods that were valuable for their weight.
Silk was also a gift. In the Han period, Chinese silk served as a diplomatic present, not only a commodity.
The Mongol postal system had sled dogs. At the end of the 13th century, Kublai Khan’s directly ruled lands had more than 1,400 stations and bridges. They also had 3,000 sled dogs in northern Manchuria.
FAQ
Where did the Silk Road start and end?
There was no single start or end point. In China, a key corridor ran from Chang’an and Luoyang toward Central Asia. In Anatolia, the Ministry of Culture and Tourism lists routes that end in Istanbul and Edirne, plus ports such as Trabzon, Sinop, Alanya and Antalya.
Was the Silk Road one road?
No. It was a trade network made of different routes. Their use changed with economic and political conditions, according to UNESCO.
Did one caravan travel the whole way from China?
Usually not. Caravans often covered certain sections and sold their loads to other traders at intermediate markets.
What was traded besides silk?
UNESCO lists spices, grain, animal skins, metalwork and precious stones. Sogdian letters also mention musk, pepper, silver and linen.
Who named it the Silk Road?
The German geographer Ferdinand von Richthofen popularised the German name Seidenstraße in 1877.
