Section: Military use of Metals
Variable: Steel (All coded records)
The absence or presence of steel as a military technology used in warfare. Steel is an alloy that includes iron, so a polity that uses bronze in warfare is familiar with copper technology and probably uses it to at least a limited extent. Consequently, if a culture uses steel in warfare and there is no mention of using iron then 'inferred present' is probably best.

48 Chuuk - Early Truk unknown Suspected Expert -
LeBar claims early evidence for the use of iron and steel tools acquired through trade with other islands: ’It appears that during this early period, and for some time thereafter, the Trukese were in contact with Guam and other islands in the Marianas due to the fact that atoll islanders to the west of Truk regularly voyaged to Guam and back, taking with them items for trade in return for which they brought back iron and steel implements. The Trukese were thus in possession of iron tools at a very early date.’ [1] However, it isn’t clear if this metal was used in warfare.

For example, swords. Noric steel first made by the Celts in 300 BCE. Romans imported Noric steel. Noricum, a region of the Austrian Alps "between Raetia in the west and Pannonia in the east" became a province within the Roman Empire. [1] However, use of Noric steel could hardly have been typical. "A sword from the Roman Republican period (3rd-2nd century BCE) in Slovenia was found to have an iron edge and a steel (0.4%C) body, like the much later spatha discussed below; a particularly unfortunate combination."

On the other hand the armouries of Constantinople itself were capable of producing numbers of complex bronze, iron and steel weapons at short notice - for example for the Cretan expedition of 949." [3] Al-Kindi (801-870 CE) in a letter to the Caliph of Baghdad mentions that "swords may be made out of shaburqan by Rus, Slavs & Byzantines". Shaburqan meant ’hard iron.’ Al-Kindi also said the Byzantines and others also made narmahan (’soft iron’). [4]

Metals acquired through trade gradually displaced wooden and stone tools: "The tomahawk succeeded the war-club, as the rifle did the bow. With the invention of this terrible implement of warfare the red man had nothing to do, except in having it so fashioned as to be adapted to his taste and usage. The tomahawk is known as widely as the Indian, and the two names have become apparently inseparable. They are made of steel, brass, or iron." [1] There were considerable time-lags when it comes to the adoption of metal weapons among different indigenous groups of the North-East: "The Northeast was crisscrossed by an extensive series of trade routes that consisted of rivers and short portages. The Huron used these routes to travel to the Cree and Innu peoples, while the Iroquois used them to travel to the Iroquoians on the Atlantic coast. The French claimed the more northerly area and built a series of trade entrepôts at and near Huron communities, whose residents recognized the material advantages of French goods as well as the fortifications’ defensive capabilities. The Huron alliance quickly became the gatekeeper of trade with the Subarctic, profiting handsomely in this role. Its people rapidly adopted new kinds of material culture, particularly iron axes, as these were immensely more effective in shattering indigenous wooden armour than were traditional stone tomahawks." [2] "For a period of time the new weapons enabled the Huron confederacy to gain the upper hand against the Iroquois, who did not gain access to European goods as quickly as their foes. By about 1615 the long traditions of interethnic conflict between the two alliances had become inflamed, and each bloc formally joined with a member of another traditional rivalry-the French or the English. Initially the Huron-French alliance held the upper hand, in no small part because the French trading system was in place several years before those of the Dutch and English. The indigenous coalitions became more evenly matched after 1620, however, as the Dutch and English trading system expanded. These Europeans began to make guns available for trade, something the French had preferred not to do. The Huron found that the technological advantage provided by iron axes was emphatically surpassed by that of the new firearms." [2] We have adopted 1620 as a provisional date of transition.

104 Early A'chik absent Inferred Expert -
Guns were absent prior to colonization, but axes, spears and swords are reported: ‘Implements which are mainly used by the Garos are very few in number. Mongreng is a variety of axe, and banuk or oaiseng is another variety. Besides these, they have spears with very big iron heads. They also have mellam, i.e., a short sword, about three feet long. It is made of iron and is straight in shape with sharpened end on both sides. It has a horizontal narrow crossbar from two ends of which they usually tie the taft tail hair of bulls or of yak if they can manage to purchase it from upper districts of Assam. Yaks’ tail is very much in demand by the Garos, and they consider it as a precious possession. The lowermost portion of the sword serves as the grip which is pointed at the end. This, they say, helps them to stick the sword on the ground when necessary.’ [1] ‘The only property which has acquired prestige value after the contact of the Garo with the outside world is the gun (Garos did not have firearms before British occupation). It is not only a useful device to protect the household from enemies, for hunting (in fact, it is the only weapon of hunting of the present day Garos or for killing and warding off wild animals. Besides, a household possessing a gun enjoys a special prestige.’ [2] The sources mention iron rather than steel. We have therefore assumed that steel was absent prior to the British colonial period.

106 Akan - Pre-Ashanti absent Confident Expert -
Akan rulers and fighters started to acquire firearms and wrap them in brass wire at some point in the colonial period: "Gun barrels were wrapped with brass wire or tightly bound cloth to minimise the risk of bursting, a perpetual problem with ill-maintained poor-quality firearms, charged or overcharged with unreliable gunpowder. The addition of golden ‘cockle’ shells was less obviously functional. The way such shells came to adorn guns and ammunition belts again indicates how the exotic was assimilated into Akan culture." [1] It remains to be confirmed when this process started. According to this Wikipedia article, firearms were not in widespread use before the Ashanti period: ’The Ashanti became familiar with firearms in the 18th century, and by the 19th century, the bulk of their best troops were armed with a variety of guns, such as the standard European trade muskets, 6 feet in length, so-called "Long Dane".’ [2]

[2] [3] Use of Damascene steel certainly by 540 CE: "This unique type of steel was a major technological innovation and Iran played an important role in its production over the centuries. Circumstantial evidence suggests that a trade in a special steel, conceivably the ingots from which damascene steel was made, was underway in the Parthian and Sasanian period. Sometime after 115 A.D. the Parthians were importing iron (steel) from some point to the east" [4] "High-carbon steel was being produced in the eastern Iranian region from the tenth century CE." [5]

Could the same thing be said up until the time of the first manufacture of Damascene swords? "It is believed that Indian steel was exported in the early centuries A.D. and was known even in the time of Alexander. By the sixth century there is more definite evidence of the manufacture of Damascene swords and the steel used for this purpose came from India." [1] Artaxerxes II of Persia (Achaemenids, ruled around 400 BCE) had a Greek physician called Ctesias of Cnidus who was impressed by his sword of Indian steel. [2] [3] Use of Damascene steel certainly by 540 CE: "This unique type of steel was a major technological innovation and Iran played an important role in its production over the centuries. Circumstantial evidence suggests that a trade in a special steel, conceivably the ingots from which damascene steel was made, was underway in the Parthian and Sasanian period. Sometime after 115 A.D. the Parthians were importing iron (steel) from some point to the east" [4] "High-carbon steel was being produced in the eastern Iranian region from the tenth century CE." [5]

At this time in Central Asia if high-quality steel was used it would have been imported. The following sources suggest later dates for fine steel. However we code present because the Kushans occupied northern India (a location repeatedly associated with fine steel) which as early as 1st CE was exporting iron and steel as far as East Africa. [1] Reference for high quality of the steel (no beginning date provided): “In the context of this work, it is important to note that crucible steel of fine quality was made at Herat, in Bukhara and in northern India.” [2] Reference for high quality of the steel (this one dates from 900 CE): "Further east from Merv along the Silk Road is a region praised for its iron and steel production by Greek, Islamic, and Chinese writers. The Sogdian state of Ustrushana, a mountainous region east of Samarkand, and the Ferghana basin ... material related to the medieval iron and steel industry has been uncovered here. Most relevant ... is a workshop excavated at a city-site of the +9th-13th centuries in Feghana, at Eski Achsy, Uzbekistan. ..” Crucible fragments ”The excavators consider that the process used here was direct production of steel from ore, just as He Tangkun argues for the Luoyang crucibles. It is quite possible, however, that they were (also) used in co-fusion steel production as suggested by the Merv excavators." [3] Fine steel swords may have been produced at an earlier time than 900 CE with the technology coming from northern India or from this region via Persia: In Tibet c700 CE "steel swords were certainly available through trade with Sogdia and Fergana ... and many steel blades are known from Central Asia from the late first millennium until the arrival of Genghis Khan in the early thirteenth century." [4] "The Sogdian cities of Samarqand and Bukhara probably also manufactured iron and steel weapons that were exported to Tibet. We know that by the early eighth century, the Sogdians, having probably borrowed the technology from the Sasanians, were manufacturing mail armor and offered suits of the material as gifts to the Tang court in 718. ... The Sasasnians may themselves have developed knowledge of steelmaking from contacts with northern India." [5] "The principal centres for the manufacture of steel weapons in Central Asia were Khwarazm, Ferghana and northern India.” [2] Burnished steel represented in image of warrior. [6]

The tama hagane was the first quality steel used in swords." [1] References that support tamahagane steel being better than the first steels produced in Japan: "Present study elucidates that the tatara iron and its manufacturing procedure gives distinctive features to Japanese swords which is different from ordinary steel. It is also notable that Japanese swordsmith utilized lath martensite without knowing details about it."

’By the Yayoi Period (50-250 CE) iron tools became more plentiful, as is evidenced by advances in woodworking technologies. By the last century of the Yayoi, iron-working technologies spread quickly across the central region of Japan from west to east. Over the course of the next several hundred years, iron completely replaced stone as the mineral of choice. Iron swords, armor, and arrowheads came to occupy prominent places in the tombs of the Kofun period. From that time onward, iron and its alloy with carbon, steel, were Japan’s pre-eminent proto-industrial metals.’ [1]

Some ethnographers and travelers report the use of iron and steel tools for the Ecuadorian period. ’The Jesuits were shortly forced to withdraw from Gualaquiza and Macas due to political reasons, but they left behind them at Gualaquiza a few mestizos who constituted the first new permanent white settlement in the Jívaro region since 1599. These mestizos seem to have been tolerated by the Jívaro as a source of Western-manufactured goods, especially machetes and steel lance heads, the latter specially manufactured in the adjacent highland province of Azuay for the Jívaro trade.’ [1] It remains to be confirmed when the Shuar started to acquire iron and steel tools. We have provisionally assumed this to coincide with the onset of the Ecuadorian period. This remains in need of confirmation.

[1] First high-quality steel 450 CE. Japan exported steel swords to China (time not stated, possibly once the Japanese had refined their methods, before the Song Dynasty). [2] "according to Wagner there is no direct evidence that cast steel was made in China. ... Exports of bin iron from Persia and Jaguda (Ghazni) to China in 6th-7th centuries are recorded. This was an imported steel of high quality. Curiously, bin iron disappears from Chinese sources after the 7th century, then reappears from 10th-17th centuries. This might have been a consequence of the Islamic conquest of Persia, followed by the rise of trade routes to China used by Arabs. An account of an embassy sent by the Yuan to Hulagu Khan in 1259 mention that bin iron was made in India." [3]

At this time in Central Asia if high-quality steel was used it would have been imported. The following sources suggest later dates for fine steel. However we code present because the Kidarites occupied northern India (a location repeatedly associated with fine steel) which as early as 1st CE was exporting iron and steel as far as East Africa. [1] Reference for high quality of the steel (no beginning date provided): “In the context of this work, it is important to note that crucible steel of fine quality was made at Herat, in Bukhara and in northern India.” [2] Reference for high quality of the steel (this one dates from 900 CE): "Further east from Merv along the Silk Road is a region praised for its iron and steel production by Greek, Islamic, and Chinese writers. The Sogdian state of Ustrushana, a mountainous region east of Samarkand, and the Ferghana basin ... material related to the medieval iron and steel industry has been uncovered here. Most relevant ... is a workshop excavated at a city-site of the +9th-13th centuries in Feghana, at Eski Achsy, Uzbekistan. ..” Crucible fragments ”The excavators consider that the process used here was direct production of steel from ore, just as He Tangkun argues for the Luoyang crucibles. It is quite possible, however, that they were (also) used in co-fusion steel production as suggested by the Merv excavators." [3] Fine steel swords may have been produced at an earlier time than 900 CE with the technology coming from northern India or from this region via Persia: In Tibet c700 CE "steel swords were certainly available through trade with Sogdia and Fergana ... and many steel blades are known from Central Asia from the late first millennium until the arrival of Genghis Khan in the early thirteenth century." [4] "The Sogdian cities of Samarqand and Bukhara probably also manufactured iron and steel weapons that were exported to Tibet. We know that by the early eighth century, the Sogdians, having probably borrowed the technology from the Sasanians, were manufacturing mail armor and offered suits of the material as gifts to the Tang court in 718. ... The Sasasnians may themselves have developed knowledge of steelmaking from contacts with northern India." [5] "The principal centres for the manufacture of steel weapons in Central Asia were Khwarazm, Ferghana and northern India.” [2]

At this time in Central Asia if high-quality steel was used it would have been imported. The following sources suggest later dates for fine steel. Reference for high quality of the steel (no beginning date provided): “In the context of this work, it is important to note that crucible steel of fine quality was made at Herat, in Bukhara and in northern India.” [1] Reference for high quality of the steel (this one dates from 900 CE): "Further east from Merv along the Silk Road is a region praised for its iron and steel production by Greek, Islamic, and Chinese writers. The Sogdian state of Ustrushana, a mountainous region east of Samarkand, and the Ferghana basin ... material related to the medieval iron and steel industry has been uncovered here. Most relevant ... is a workshop excavated at a city-site of the +9th-13th centuries in Feghana, at Eski Achsy, Uzbekistan. ..” Crucible fragments ”The excavators consider that the process used here was direct production of steel from ore, just as He Tangkun argues for the Luoyang crucibles. It is quite possible, however, that they were (also) used in co-fusion steel production as suggested by the Merv excavators." [2] Fine steel swords may have been produced at an earlier time than 900 CE with the technology coming from northern India or from this region via Persia: In Tibet c700 CE "steel swords were certainly available through trade with Sogdia and Fergana ... and many steel blades are known from Central Asia from the late first millennium until the arrival of Genghis Khan in the early thirteenth century." [3] "The Sogdian cities of Samarqand and Bukhara probably also manufactured iron and steel weapons that were exported to Tibet. We know that by the early eighth century, the Sogdians, having probably borrowed the technology from the Sasanians, were manufacturing mail armor and offered suits of the material as gifts to the Tang court in 718. ... The Sasasnians may themselves have developed knowledge of steelmaking from contacts with northern India." [4] "The principal centres for the manufacture of steel weapons in Central Asia were Khwarazm, Ferghana and northern India.” [1]

First steel adapted by Chu in 5th century BCE [1] , likely spread quickly to other states "As the smiths in time learned the possibilities of their material, and began producing quench-hardened steel swords ... bronze swords could not longer compete and went out of use completely. This seems likely to have occurred all over China by the late third century B.C. at the latest." [2] Wootz steel was "being exported from India to China at least as early as the +5th century. … good steel was manufactured in China by remarkably modern methods at least from that time onwards also." [3] First high-quality steel 450 CE.

"Wootz steel was "being exported from India to China at least as early as the +5th century. … good steel was manufactured in China by remarkably modern methods at least from that time onwards also." [1] First high-quality steel 450 CE. Japan exported steel swords to China (time not stated, possibly once the Japanese had refined their methods, before the Song Dynasty). [2] "according to Wagner there is no direct evidence that cast steel was made in China. ... Exports of bin iron from Persia and Jaguda (Ghazni) to China in 6th-7th centuries are recorded. This was an imported steel of high quality. Curiously, bin iron disappears from Chinese sources after the 7th century, then reappears from 10th-17th centuries. This might have been a consequence of the Islamic conquest of Persia, followed by the rise of trade routes to China used by Arabs. An account of an embassy sent by the Yuan to Hulagu Khan in 1259 mention that bin iron was made in India." [3]

Langebaek’s intent to understand the appropriation of Spanish weapons and tools, such as helmets, swords, arquebuses and steel axes, as a form of acculturation of Tairona caciques and warriors, is another mode of analysis which reduces the adoption of these goods to utilitarian terms. He supposes that these objects were automatically incorporated by the Taironas because of their inherent technological value, and that the Spaniards controlled the flow of goods. "El intento de Langebaek (1985:80- 84) por entender la apropiación de armas y herramientas españolas, notablemente los yelmos, espadas, arcabuces y hachas de acero, por parte de los guerreros y caciques taironas como una forma de aculturación, es otro modo de análisis que reduce la adopción de estos bienes a términos utilitarios.

[1] Reference for high quality of the steel (no beginning date provided): “In the context of this work, it is important to note that crucible steel of fine quality was made at Herat, in Bukhara and in northern India.” [2] Reference for high quality of the steel (this one dates from 900 CE): "Further east from Merv along the Silk Road is a region praised for its iron and steel production by Greek, Islamic, and Chinese writers. The Sogdian state of Ustrushana, a mountainous region east of Samarkand, and the Ferghana basin ... material related to the medieval iron and steel industry has been uncovered here. Most relevant ... is a workshop excavated at a city-site of the +9th-13th centuries in Feghana, at Eski Achsy, Uzbekistan. ..” Crucible fragments ”The excavators consider that the process used here was direct production of steel from ore, just as He Tangkun argues for the Luoyang crucibles. It is quite possible, however, that they were (also) used in co-fusion steel production as suggested by the Merv excavators." [3] Fine steel swords may have been produced at an earlier time than 900 CE with the technology coming from northern India or from this region via Persia: In Tibet c700 CE "steel swords were certainly available through trade with Sogdia and Fergana ... and many steel blades are known from Central Asia from the late first millennium until the arrival of Genghis Khan in the early thirteenth century." [4] "The Sogdian cities of Samarqand and Bukhara probably also manufactured iron and steel weapons that were exported to Tibet. We know that by the early eighth century, the Sogdians, having probably borrowed the technology from the Sasanians, were manufacturing mail armor and offered suits of the material as gifts to the Tang court in 718. ... The Sasasnians may themselves have developed knowledge of steelmaking from contacts with northern India." [5] "The principal centres for the manufacture of steel weapons in Central Asia were Khwarazm, Ferghana and northern India.” [2]

371 Yemen - Qasimid Dynasty present Confident Expert -
Rifles were present: ’But al-jirafi goes on, more importantly, to relate that al-Ahmar wrote al-Mansur al-Husayn a brusque letter demanding a meeting. The Imam feared an attempt at assassination; so he’assassinated alAhmar first, stuck his head on a lance, and galloped off with it through a hail of bullets from the shaykh’s enraged tribesmen (aljirafi 1951: 182). In fact, al-Ahrnar, accompanied by Bin juzaylan of DhU Muhammad and by Ahmad Muhammad Hubaysh of Sufyan, seems to have come to ’Asir, just outside San’a’, to seek a settlement (Zabarah 1941: 539 and 1958: 486). The details are probably lost forever, and we are told only that al-Ahmar ’had wished to make independent his own rule of part of the country’ (ibid.), which he very well may have done; but al-Mansur alHusayn’s view of the matter, as recorded in the histories, has all the vigorous clarity of the Zaydi tradition. The taunt to the tribesmen at the time was, typically, that they were no better than polytheists: he brandished al-Ahmar’s head on his spear and cried ’this is the head of your idol’.’ [1]
