91-644: The Principio Iron Works were started here in 1719 by Joseph Farmer with British capital and an ironmaster, John England. By the 1740s, it had become one of the most successful colonial ironworks, producing pig iron for sale in London. Later, Thomas Russell, Jr., England's successor, produced cannonballs for the Continental Army during the American Revolution . The works were part of the (larger) Principio Company, whose other holdings included

182-539: A "complex network of trade routes" that gave people the chance to exchange goods and culture. A maritime Silk Route opened up between Chinese-controlled Giao Chỉ (centred in modern Vietnam , near Hanoi ), probably by the 1st century. It extended, via ports on the coasts of India and Sri Lanka , all the way to Roman -controlled ports in Roman Egypt and the Nabataean territories on the northeastern coast of

273-596: A "silk" one in particular. William Dalrymple points out that in pre-modern times, maritime travel cost only a fifth of overland transport, and argues for the pre-13th century primacy of an India-dominated " Golden Road " extending from Rome to Japan. The southern stretches of the Silk Road, from Khotan ( Xinjiang ) to Eastern China, were first used for jade and not silk, as long as 5000 BCE , and are still in use for this purpose. The term "Jade Road" would have been more appropriate than "Silk Road" had it not been for

364-755: A Chinese tomb of Shanxi province dated to the Sui dynasty (581–618). Both the Old Book of Tang and New Book of Tang , covering the history of the Chinese Tang dynasty (618–907), record that a new state called Fu-lin (拂菻; i.e. Byzantine Empire) was virtually identical to the previous Daqin (大秦; i.e. Roman Empire). Several Fu-lin embassies were recorded for the Tang period, starting in 643 with an alleged embassy by Constans II (transliterated as Bo duo li , 波多力, from his nickname "Kōnstantinos Pogonatos") to

455-478: A central channel or "runner", resembling a litter of piglets being nursed by a sow . When the metal had cooled and hardened, the smaller ingots (the "pigs") were simply broken from the runner (the "sow"), hence the name "pig iron". As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand are insignificant issues when compared to the ease of casting and handling. The Chinese were already making pig iron during

546-631: A contingent of Roman legionaries. The Romans may have been part of Antony 's army invading Parthia . Sogdiana (modern Bukhara ), east of the Oxus River, on the Polytimetus River, was apparently the most easterly penetration ever made by Roman forces in Asia. The margin of Chinese victory appears to have been their crossbows, whose bolts and darts seem easily to have penetrated Roman shields and armour. The Han dynasty army regularly policed

637-737: A leading astronomer and physician in Khanbaliq , at the court of Kublai Khan , Mongol founder of the Yuan dynasty (1271–1368) and was even granted the noble title 'Prince of Fu lin' ( Chinese : 拂菻王; Fú lǐn wáng). The Uyghur Nestorian Christian diplomat Rabban Bar Sauma , who set out from his Chinese home in Khanbaliq (Beijing) and acted as a representative for Arghun (a grandnephew of Kublai Khan), traveled throughout Europe and attempted to secure military alliances with Edward I of England , Philip IV of France , Pope Nicholas IV , as well as

728-405: A means of currency, just as valuable as silk yarn and textiles. Under its strong integrating dynamics on the one hand and the impacts of change it transmitted on the other, tribal societies previously living in isolation along the Silk Road, and pastoralists who were of barbarian cultural development, were drawn to the riches and opportunities of the civilisations connected by the routes, taking on

819-486: A number of important technologies, and in addition to raiding vulnerable settlements for these commodities, they also encouraged long-distance merchants as a source of income through the enforced payment of tariffs. Sogdians played a major role in facilitating trade between China and Central Asia along the Silk Roads as late as the 10th century, their language serving as a lingua franca for Asian trade as far back as

910-571: Is a modern name, acquired from its similarity to the overland Silk Road. Like the overland routes, the ancient maritime routes through Southeast Asia and the Indian Ocean had no particular name for the majority of its very long history. Despite the modern name, the Maritime Silk Road involved exchanges in a wide variety of goods over a very wide region, not just silk or Asian exports. It differed significantly in several aspects from

1001-596: Is burned off and the alloy composition controlled. Earlier processes for this included the finery forge , the puddling furnace , the Bessemer process , and the open hearth furnace . Modern steel mills and direct-reduction iron plants transfer the molten iron to a ladle for immediate use in the steel making furnaces or cast it into pigs on a pig-casting machine for reuse or resale. Modern pig casting machines produce stick pigs, which break into smaller 4–10 kg piglets at discharge. Silk Road The Silk Road

1092-499: Is melted and a strong current of air is directed over it while it is stirred or agitated. This causes the dissolved impurities (such as silicon) to be thoroughly oxidized. An intermediate product of puddling is known as refined pig iron , finers metal , or refined iron . Pig iron can also be used to produce gray iron . This is achieved by remelting pig iron, often along with substantial quantities of steel and scrap iron, removing undesirable contaminants, adding alloys, and adjusting

1183-532: The Accokeek or Potomac Ironworks on the land of George Washington's father, Augustine Washington (north of Ferry Farm near Fredericksburg, Virginia ). This works was originally developed by the ironmaster England as a source of iron ore. As early as 1726, it may have included a cold blast charcoal furnace . Accokeek/Potomac served as the headquarters of the Principio Company until it was closed in

1274-793: The Alans ], Lijian [Syria under the Greek Seleucids], Tiaozhi (Mesopotamia), and Tianzhu [northwestern India] ... As a rule, rather more than ten such missions went forward in the course of a year, and at the least five or six. ( Hou Hanshu , Later Han History). These connections marked the beginning of the Silk Road trade network that extended to the Roman Empire. The Chinese campaigned in Central Asia on several occasions, and direct encounters between Han troops and Roman legionaries (probably captured or recruited as mercenaries by

1365-656: The Berel burial ground in Kazakhstan , confirmed that the nomadic Arimaspians were not only breeding horses for trade but also produced great craftsmen able to propagate exquisite art pieces along the Silk Road. From the 2nd millennium BCE, nephrite jade was being traded from mines in the region of Yarkand and Khotan to China. Significantly, these mines were not very far from the lapis lazuli and spinel ("Balas Ruby") mines in Badakhshan , and, although separated by

1456-849: The Hungarian plain and the Carpathian Mountains to the Chinese Gansu Corridor, and linking the Middle East with Northern India and the Punjab , undoubtedly played an important role in the development of the Silk Road. Scythians accompanied the Assyrian Esarhaddon on his invasion of Egypt, and their distinctive triangular arrowheads have been found as far south as Aswan . These nomadic peoples were dependent upon neighbouring settled populations for

1547-779: The Karakum Desert . Both routes joined the main southern route before reaching ancient Merv , Turkmenistan. Another branch of the northern route turned northwest past the Aral Sea and north of the Caspian Sea , then and on to the Black Sea. A route for caravans, the northern Silk Road brought to China many goods such as "dates, saffron powder and pistachio nuts from Persia; frankincense , aloes and myrrh from Somalia ; sandalwood from India; glass bottles from Egypt, and other expensive and desirable goods from other parts of

1638-564: The Kushan Empire between the first and third centuries reinforced the role of the powerful merchants from Bactria and Taxila . They fostered multi-cultural interaction as indicated by their 2nd century treasure hoards filled with products from the Greco-Roman world, China, and India, such as in the archeological site of Begram . The Silk Road trade did not sell only textiles, jewels, metal and cosmetic, but also slaves, connecting

1729-991: The Magyars , Armenians , and Chinese. The Silk Road reached its peak in the west during the time of the Byzantine Empire ; in the Nile- Oxus section, from the Sassanid Empire period to the Il Khanate period; and in the sinitic zone from the Three Kingdoms period to the Yuan dynasty period. Trade between East and West also developed across the Indian Ocean , between Alexandria in Egypt and Guangzhou in China. Persian Sassanid coins emerged as

1820-758: The Malay Peninsula , and the Mekong Delta ; through which passed the main routes of the Austronesian trade ships to Giao Chỉ (in the Tonkin Gulf ) and Guangzhou (southern China ), the endpoints (later also including Quanzhou by the 10th century CE). Secondary routes also passed through the coastlines of the Gulf of Thailand ; as well as through the Java Sea , Celebes Sea , Banda Sea , and

1911-862: The Maldives . It branches from here into routes through the Arabian Sea entering the Gulf of Oman (into the Persian Gulf ), and the Gulf of Aden (into the Red Sea ). Secondary routes also pass through the coastlines of the Bay of Bengal , the Arabian Sea, and southwards along the coast of East Africa to Zanzibar , the Comoros , Madagascar , and the Seychelles .

2002-520: The Persian Gulf and Red Sea into Persia , Mesopotamia (sailing up the Euphrates River in modern-day Iraq ), Arabia , Egypt , Aksum (Ethiopia), and Somalia in the Horn of Africa . The Silk Road represents an early phenomenon of political and cultural integration due to inter-regional trade. In its heyday, it sustained an international culture that strung together groups as diverse as

2093-884: The Red Sea . The earliest Roman glassware bowl found in China was unearthed from a Western Han tomb in Guangzhou , dated to the early 1st century BCE, indicating that Roman commercial items were being imported through the South China Sea . According to Chinese dynastic histories , it is from this region that the Roman embassies arrived in China, beginning in 166 CE during the reigns of Marcus Aurelius and Emperor Huan of Han . Other Roman glasswares have been found in Eastern-Han-era tombs (25–220 CE) further inland in Luoyang , Nanyang , and Nanjing . Soon after

2184-745: The Sasanian Empire that allowed the Byzantines to bypass the Sasanian merchants and trade directly with the Sogdians for purchasing Chinese silk. Although the Byzantines had already procured silkworm eggs from China by this point, the quality of Chinese silk was still far greater than anything produced in the West, a fact that is perhaps emphasized by the discovery of coins minted by Justin II found in

2275-558: The Silk Road and Viking contacts with Persia, but there is a chronological gap between the Viking period and Lapphyttan. Smelting and producing wrought iron were known in ancient Europe and the Middle East, but it was produced in bloomeries by direct reduction . Small prills of pig iron dispersed in slag are produced in all iron furnaces, but the operator of a bloomery had to avoid conditions causing the phase transition of

2366-575: The Silla Kingdom in Gyeongju , Korea. Chinese wealth grew as they delivered silk and other luxury goods to the Roman Empire, whose wealthy women admired their beauty. The Roman Senate issued, in vain, several edicts to prohibit the wearing of silk, on economic and moral grounds: the import of Chinese silk caused a huge outflow of gold, and silk clothes were considered decadent and immoral. I can see clothes of silk, if materials that do not hide

2457-668: The Sulu Sea , reconnecting with the main route through the northern Philippines and Taiwan . The secondary routes also continue onward to the East China Sea and the Yellow Sea for a limited extent. The main route of the western regions of the Maritime Silk Road directly crosses the Indian Ocean from the northern tip of Sumatra (or through the Sunda Strait ) to Sri Lanka , southern India and Bangladesh , and

2548-715: The Wusun . Zhang Qian's report suggested the economic reason for Chinese expansion and wall-building westward, and trail-blazed the Silk Road, making it one of the most famous trade routes in history and in the world. After winning the War of the Heavenly Horses and the Han–Xiongnu War , Chinese armies established themselves in Central Asia, initiating the Silk Route as a major avenue of international trade. Some say that

2639-468: The iron industry in the production of steel . It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7 %, along with silica and other dross , which makes it brittle and not useful directly as a material except for limited applications. The traditional shape of the molds used for pig iron ingots is a branching structure formed in sand , with many individual ingots at right angles to

2730-428: The 12th century, the route was used to ship bullion from Yunnan (gold and silver are among the minerals in which Yunnan is rich), through northern Burma, into modern Bangladesh , making use of the ancient route, known as the 'Ledo' route. The emerging evidence of the ancient cities of Bangladesh, in particular Wari-Bateshwar ruins, Mahasthangarh , Bhitagarh , Bikrampur , Egarasindhur, and Sonargaon , are believed to be

2821-703: The 4th century. The Silk Road was initiated and spread by China's Han dynasty through exploration and conquests in Central Asia . With the Mediterranean linked to the Fergana Valley , the next step was to open a route across the Tarim Basin and the Hexi Corridor to China Proper . This extension came around 130 BCE, with the embassies of the Han dynasty to Central Asia following the reports of

2912-736: The 640s and 650s. During Emperor Taizong's reign alone, large campaigns were launched against not only the Göktürks , but also separate campaigns against the Tuyuhun , the oasis states , and the Xueyantuo . Under Emperor Taizong , Tang general Li Jing conquered the Eastern Turkic Khaganate . Under Emperor Gaozong , Tang general Su Dingfang conquered the Western Turkic Khaganate , an important ally of

3003-439: The Byzantine empire. After these conquests, the Tang dynasty fully controlled the Xiyu , which was the strategic location astride the Silk Road. This led the Tang dynasty to reopen the Silk Road, with this portion named the Tang-Tubo Road ("Tang-Tibet Road") in many historical texts. The Tang dynasty established a second Pax Sinica , and the Silk Road reached its golden age, whereby Persian and Sogdian merchants benefited from

3094-437: The Byzantine ruler Andronikos II Palaiologos . Andronikos II had two half-sisters who were married to great-grandsons of Genghis Khan , which made him an in-law with the Yuan-dynasty Mongol ruler in Beijing, Kublai Khan. The History of Ming preserves an account where the Hongwu Emperor , after founding the Ming dynasty (1368–1644), had a supposed Byzantine merchant named Nieh-ku-lun (捏古倫) deliver his proclamation about

An ancient "travel guide" to this Indian Ocean trade route was the Greek Periplus of the Erythraean Sea written in 60 CE. The travelling party of Maës Titianus penetrated farthest east along

3276-478: The Chinese Emperor Wu became interested in developing commercial relationships with the sophisticated urban civilizations of Ferghana, Bactria, and the Parthian Empire : "The Son of Heaven on hearing all this reasoned thus: Ferghana (Dayuan "Great Ionians " ) and the possessions of Bactria ( Ta-Hsia ) and Parthian Empire ( Anxi ) are large countries, full of rare things, with a population living in fixed abodes and given to occupations somewhat identical with those of

3367-412: The Chinese people, but with weak armies, and placing great value on the rich produce of China" ( Hou Hanshu , Later Han History ). Others say that Emperor Wu was mainly interested in fighting the Xiongnu and that major trade began only after the Chinese pacified the Hexi Corridor . The Chinese were also strongly attracted by the tall and powerful horses (named " heavenly horses ") in the possession of

3458-407: The Dayuan (literally the "Great Ionians," the Greek kingdoms of Central Asia ), which were of capital importance in fighting the nomadic Xiongnu. They defeated the Dayuan in the Han-Dayuan war . The Chinese subsequently sent numerous embassies, around ten every year, to these countries and as far as Seleucid Syria. Thus more embassies were dispatched to Anxi [Parthia], Yancai [who later joined

3549-437: The East included tea, dyes, perfumes, and porcelain ; among Western exports were horses, camels, honey, wine, and gold. Aside from generating substantial wealth for emerging mercantile classes, the proliferation of goods such as paper and gunpowder greatly affected the trajectory of political history in several theatres in Eurasia and beyond. The Silk Road was utilized over a period that saw immense political variation across

3640-510: The Empire as a whole. The Roman-style glassware discovered in the archeological sites of Gyeongju , the capital of the Silla kingdom (Korea) showed that Roman artifacts were traded as far as the Korean peninsula. The Greco- Roman trade with India started by Eudoxus of Cyzicus in 130 BCE continued to increase, and according to Strabo (II.5.12), by the time of Augustus , up to 120 ships were setting sail every year from Myos Hormos in Roman Egypt to India. The Roman Empire connected with

3822-436: The German term Seidenstraße (literally "Silk Road") and was first popularized in 1877 by Ferdinand von Richthofen , who made seven expeditions to China from 1868 to 1872. However, the term itself had been in use in decades prior to that. The alternative translation "Silk Route" is also used occasionally. Although the term was coined in the 19th century, it did not gain widespread acceptance in academia or popularity among

3913-400: The Han general dispatched envoy Gan Ying to Daqin (Rome). The Silk Road essentially came into being from the 1st century BCE, following these efforts by China to consolidate a road to the Western world and India , both through direct settlements in the area of the Tarim Basin and diplomatic relations with the countries of the Dayuan, Parthians and Bactrians further west. The Silk Roads were

4004-432: The Roman conquest of Egypt in 30 BCE, regular communications and trade between China, Southeast Asia, India, the Middle East, Africa, and Europe blossomed on an unprecedented scale. The Roman Empire inherited eastern trade routes that were part of the Silk Road from the earlier Hellenistic powers and the Arabs. With control of these trade routes, citizens of the Roman Empire received new luxuries and greater prosperity for

4095-587: The Roman craze for Chinese silk (supplied through the Parthians), even though the Romans thought silk was obtained from trees. This belief was affirmed by Seneca the Younger in his Phaedra and by Virgil in his Georgics . Notably, Pliny the Elder knew better. Speaking of the bombyx or silk moth, he wrote in his Natural Histories "They weave webs, like spiders, that become a luxurious clothing material for women, called silk." The Romans traded spices, glassware, perfumes, and silk. Roman artisans began to replace yarn with valuable plain silk cloths from China and

4186-421: The Silk Road from the Mediterranean world, probably with the aim of regularising contacts and reducing the role of middlemen, during one of the lulls in Rome's intermittent wars with Parthia, which repeatedly obstructed movement along the Silk Road. Intercontinental trade and communication became regular, organised, and protected by the "Great Powers." Intense trade with the Roman Empire soon followed, confirmed by

4277-419: The Silk Road slave trade to the Bukhara slave trade as well as the Black Sea slave trade , particularly slave girls. Byzantine Greek historian Procopius stated that two Nestorian Christian monks eventually uncovered the way silk was made. From this revelation, monks were sent by the Byzantine Emperor Justinian (ruled 527–565) as spies on the Silk Road from Constantinople to China and back to steal

4368-410: The Silk Road trade. The originating source seems sufficiently reliable, but silk degrades very rapidly, so it cannot be verified whether it was cultivated silk (which almost certainly came from China) or a type of wild silk , which might have come from the Mediterranean or Middle East. Following contacts between Metropolitan China and nomadic western border territories in the 8th century BCE, gold

Some remnants of what was probably Chinese silk dating from 1070 BCE have been found in Ancient Egypt . The Great Oasis cities of Central Asia played a crucial role in the effective functioning of

4550-474: The West for land-based trade. The Tang captured the vital route through the Gilgit Valley from Tibet in 722, lost it to the Tibetans in 737, and regained it under the command of the Goguryeo General Gao Xianzhi . While the Turks were settled in the Ordos region (former territory of the Xiongnu ), the Tang government took on the military policy of dominating the central steppe. The Tang dynasty (along with Turkic allies) conquered and subdued Central Asia during

Zhang Qian visited directly the kingdom of Dayuan in Ferghana , the territories of the Yuezhi in Transoxiana , the Bactrian country of Daxia with its remnants of Greco-Bactrian rule, and Kangju . He also made reports on neighbouring countries that he did not visit, such as Anxi ( Parthia ), Tiaozhi ( Mesopotamia ), Shendu ( Indian subcontinent ) and

In June 2014, UNESCO designated the Chang'an-Tianshan corridor of the Silk Road as a World Heritage Site , while the Indian portion remains on the tentative site list. The Silk Road derives its name from the lucrative trade in silk , first developed in China , and a major reason for the connection of trade routes into an extensive transcontinental network. It derives from

Ductile iron can also be produced using certain high purity grades of pig iron; depending on the grade of ductile iron being produced, the pig irons chosen may be low in the elements silicon, manganese, sulfur and phosphorus. High purity pig iron is used to dilute any elements in a ductile iron charge which may be harmful to the ductile iron process (except carbon). Pig iron

5096-437: The commerce between East and West. At the same time, the Chinese empire welcomed foreign cultures, making it very cosmopolitan in its urban centres. In addition to the land route, the Tang dynasty also developed the maritime Silk Route. Chinese envoys had been sailing through the Indian Ocean to India since perhaps the 2nd century BCE, yet, it was during the Tang dynasty that a strong Chinese maritime presence could be found in

5187-413: The continent, exemplified by major events such as the Black Death and the Mongol conquests . The network was highly decentralized, and security was sparse: travelers faced constant threats of banditry and nomadic raiders, and long expanses of inhospitable terrain. Few individuals traveled the entire length of the Silk Road, instead relying on a succession of middlemen based at various stopping points along

5278-599: The course of the Brahmaputra River, crossing through the Himalayas then bending westward to its source in Tibet . It is doubtless that this delta was a major international trading center, almost certainly from much earlier than the Common Era. Gemstones and other merchandise from Thailand and Java were traded in the delta and through it. Chinese archaeological writer Bin Yang and some earlier writers and archaeologists, such as Janice Stargardt, strongly suggest this route of international trade as Sichuan – Yunnan – Burma – Bangladesh route. According to Bin Yang, especially from

As it extended westwards from the ancient commercial centres of China, the overland, intercontinental Silk Road divided into northern and southern routes bypassing the Taklamakan Desert and Lop Nur . Merchants along these routes were involved in "relay trade" in which goods changed "hands many times before reaching their final destinations". The northern route started at Chang'an (now called Xi'an ), an ancient capital of China that

The Maritime Silk Road or Maritime Silk Route is the maritime section of the historic Silk Road that connected Southeast Asia , East Asia , the Indian subcontinent , the Arabian Peninsula , eastern Africa , and Europe .

Alternatively, decarburizing the pig iron into steel was an extremely tedious process using medieval technology, so in Europe before the Middle Ages the prills were discarded with the slag. Traditionally, pig iron was worked into wrought iron in finery forges , later puddling furnaces , and more recently, into steel . In these processes, pig iron

Crossing the high mountains, it passed through northern Pakistan , over the Hindu Kush mountains, and into Afghanistan , rejoining the northern route near Merv, Turkmenistan . From Merv, it followed a nearly straight line west through mountainous northern Iran , Mesopotamia , and the northern tip of the Syrian Desert to the Levant , where Mediterranean trading ships plied regular routes to Italy , while land routes went either north through Anatolia or south to North Africa . Another branch road travelled from Herat through Susa to Charax Spasinu at

Furnaces such as Lapphyttan in Sweden may date back as far back as the 12th century; and some in the County of Mark dating back to the 13th century, which is now part of Westphalia , Germany. It remains to be established whether these northern European developments were derived from the Chinese ones. Wagner has postulated a possible link via Persian contacts with China along

6279-402: The maritime spice networks between Southeast Asia and South Asia , and the West Asian maritime networks in the Arabian Sea and beyond, coinciding with these ancient maritime trade roads by the current era. Austronesian thalassocracies controlled the flow of trade in the eastern regions of the Maritime Silk Road, especially the polities around the straits of Malacca and Bangka ,

6370-425: The maritime route faced different perils like weather and piracy , but they were not affected by political instability and could simply avoid areas in conflict. Central Eurasia has been known from ancient times for its horse riding and horse breeding communities, and the overland Steppe Route across the northern steppes of Central Eurasia was in use long before that of the Silk Road. Archeological sites, such as
