Seven Silk Road destinations, from China to Italy: towns that grew rich on trade

  • Settlements along the route linking Europe and Asia thrived by providing accommodation and services for countless traders
  • Formally established during the Han dynasty, it was a 19th-century German geographer who coined the term Silk Road

We have a German geographer, cartographer and explorer to thank for the name of the world’s most famous network of transconti­nental trade routes.
Formally established during the Han dynasty, in the first and second centuries BC, it wasn’t until 1877 that Ferdinand von Richthofen coined the term Silk Road (historians increasingly favour the collective term Silk Routes).
The movement of merchandise between China and Europe had been taking place long before the Han arrived on the scene but it was they who employed troops to keep the roads safe from marauding nomads.
Commerce flourished and goods as varied as carpets and camels, glassware and gold, spices and slaves were traded; as were horses, weapons and armour.
Merchants also moved medicines but they were no match for the bubonic plague, which worked its way west along the Silk Road before devastating huge swathes of 14th century Europe.
What follows are some of the countless kingdoms, territories, (modern-day) nations and cities that grew rich on the proceeds of trade, taxes and tolls.

China

Marco Polo worked in the Mongol capital, Khanbaliq (today’s Beijing), and was struck by the level of mercantile activity.

The Venetian gap-year pioneer wrote, “Every day more than a thousand carts loaded with silk enter the city, for a great deal of cloth of gold and silk is woven here.”

Light, easy to transport items such as paper and tea provided Silk Road traders with rich pickings, but it was China’s monopoly on the luxurious shimmering fabric that guaranteed huge profits.

So much so that sneaking silk worms out of the empire was punishable by death.

The desert outpost of Dunhuang found itself at the crossroads of two major Silk Road trade arteries, one leading west through the Pamir Mountains to Central Asia and another south to India.

Built into the Great Wall at nearby Yunmenguan are the ruins of a fortified gatehouse and cus­toms post, which controlled the movement of Silk Road caravans.

Also near Dunhuang, the Mogao Caves contain one of the richest collections of Buddhist art treasures any­where in the world, a legacy of the route to and from the subcontinent.

Afghanistan

For merchants and middlemen hauling goods through Central Asia, there was no way of bypassing the mountainous lands we know today as Afghanistan.

Evidence of trade can be traced back to long before the Silk Road – locally mined lapis lazuli stones somehow found their way to ancient Egypt, and into Tutankhamun’s funeral mask, created in 1323BC.

Besides mercan­tile exchange, the caravan routes were responsible for the sharing of ideas and Afghanistan was a major beneficiary. Art, philosophy, language, science, food, architecture and technology were all exchanged, along with commercial goods.

In fact, maritime technology would eventually be the area’s undoing. By the 15th century, it had become cheaper and more convenient to transport cargo by sea – a far from ideal development for a landlocked region.

Iran

Thanks to the Silk Road and the routes that preceded it, the northern Mesopotamian region (present-day Iran) became China’s closest trading partner. Traders rarely journeyed the entire length of the trail, however.

Merchandise was passed along by middlemen who each travelled part of the way and overnighted in caravan­serai, forti­fied inns that provided accom­mo­dation, storerooms for goods and space for pack animals.

With so many wheeler-dealers gathering in one place, the hostelries developed into ad hoc marketplaces.

Marco Polo writes of the Persian kingdom of Kerman, where craftsmen made saddles, bridles, spurs and “arms of every kind”.

Today, in the centre of Kerman, the former caravanserai building forms part of the Ganjali Khan Complex, which incorporates a bazaar, bathhouse and mosque.

Uzbekistan

The double-landlocked country boasts some of the Silk Road’s most fabled destinations. Forts, such as the one still standing at Khiva, were built to protect traders from bandits; in fact, the city is so well-preserved, it is known as the Museum under the Sky.

The name Samarkand is also deeply entangled with the history of the Silk Road.

The earliest evidence of silk being used outside China can be traced to Bactria, now part of modern Uzbekistan, where four graves from around 1500BC-1200BC contained skeletons wrapped in garments made from the fabric.

Three thousand years later, silk weaving and the production and trade of textiles remain one of Samarkand’s major industries.

Georgia

Security issues in Persia led to the opening up of another branch of the legendary trade route and the first caravan loaded with silk made its way across Georgia in AD568.

Marco Polo referred to the weaving of raw silk in “a very large and fine city called Tbilisi”.

Today, the capital has shaken off the Soviet shackles and is on the cusp of going viral.

Travellers lap up the city’s monaster­ies, walled fortresses and 1,000-year-old churches before heading up the Georgian Military Highway to stay in villages nestling in the soaring Caucasus Mountains.

Public minibuses known as marshrutka labour into the foothills and although the vehicles can get cramped and uncomfortable, they beat travelling by camel.

Jordan

The location of the Nabataean capital, Petra, wasn’t chosen by chance.

Savvy nomadic herders realised the site would make the perfect pit-stop at the confluence of several caravan trails, including a route to the north through Palmyra (in modern-day Syria), the Arabian peninsula to the south and Mediterranean ports to the west.

Huge payments in the form of taxes and protection money were collected – no wonder the most magnificent of the sand­stone city’s hand-carved buildings is called the Treasury.

The Red Rose City is still a gold mine – today’s tourists pay a hefty

US$70 fee to enter Petra

. The Nabataeans would no doubt approve.

Venice

Trade enriched Venice beyond measure, helping shape the Adriatic entrepot into the floating marvel we see today.

Besides the well-documented flow of goods heading west, consignments of cotton, ivory, animal furs, grapevines and other goods passed through the strategically sited port on their way east.

Ironically, for a city built on trade and taxes, the biggest problem Venice faces today is visitors who don’t contribute enough to the local economy.

A lack of spending by millions of day-tripping tourists and cruise passengers who aren’t liable for nightly hotel taxes has prompted authorities to introduce a citywide access fee from January 2020.

Two thousand years ago, tariffs and tolls helped Venice develop and prosper. Now they’re needed to prevent its demise.

Secrets of tea plant revealed by science – BBC News

Botanists have unlocked the genetic secrets of the plant prized for producing tea.A team in China has decoded the genetic building blocks of the tea plant, Camellia sinensis, whose leaves are used for all types of tea, including black, green and oolong.

The research gives an insight into the chemicals that give tea its flavour.

Until now, little has been known about the genetics of the plant, despite its huge economic and cultural importance.

“There are many diverse flavours, but the mystery is what determines or what is the genetic basis of tea flavours?” said plant geneticist Lizhi Gao of Kunming Institute of Botany, China, who led the research.

“Together with the construction of genetic maps and new sequencing technologies, we are working on an updated tea tree genome that will investigate some of the flavour.”

The Camellia grouping, or genus, contains over 100 species, including ornamental garden plants. But only Camellia Sinensis is grown commercially for making tea.

The researchers found that the leaves of the tea plant contain high levels of chemicals that give tea its distinctive flavour. They include flavonoids and caffeine.

Other members of the Camellia genus contain these chemicals at much lower levels.

Dr Monique Simmonds, deputy director of science at Kew Royal Botanic Gardens, UK, who is not connected with the research, said it provided an important insight into the genetic building blocks of tea.

She told BBC News: ”Overall, the findings from this study could have a significant impact on those involved in the breeding of tea but also those involved in breeding many plants used medicinally and in cosmetics, as the compounds that occur in tea are often associated with the biological properties of plants used medicinally or in cosmetics.”

Decoding the genome of the tea plant took more than five years. At three billion DNA base pairs in length, the tea plant genome is more than four times the size of the coffee plant genome and much larger than most sequenced plant species.

“Our lab has successfully sequenced and assembled more than 20 plant genomes,” said Prof Gao, who carried out the work with scientists in South Korea and the US.

“But this genome, the tea tree genome, was tough.”

More than 50 types of plant have now had their genetic code laid bare

The genetic knowledge could lead to ways to improve the quality and price of tea, by selective breeding of tea plants.

Guy Barter, chief horticulturist at the Royal Horticultural Society (RHS), UK, said the work gave plant breeders a “powerful new tool”.

“Once you understand the basis for the flavours and the processing quality of the tea, you can then have genetic markers that breeders can look for when trying to produce new varieties,” he told BBC News.

Six main types of tea are produced from Camellia sinensis – white, yellow, green, oolong, black and post-fermented. Each has its own aroma, taste and appearance.The distinctive flavours of these teas are created by their different chemical compositions.

Dr Simmonds said knowledge of the genome of tea helped us understand how the plant evolved.

”Another important finding is that the biochemical pathways involved in the synthesis of the compounds important in the taste of tea are also present in some of the ancestors of tea and have been conserved for about 6.3 million years,” she said.

The first plant genome was sequenced more than 15 years ago.

Since then more than 50 types of plant have been sequenced, including food crops such as the banana, potato and tomato.

The research is published in the journal Molecular Plant.
