మానవుడు కంచును వాడిన చారిత్రిక కాలాన్ని కంచుయుగం అంటారు. కొన్ని ప్రాంతాల లోని ఆదిమ కాలపు రాతలను, పట్టణ నాగరికతల తొలినాళ్ళను కూడా కంచుయుగం గానే భావిస్తారు. పురాతన సమాజాలను వర్గీకరించడానికి, అధ్యయనం చేయడానికీ క్రిస్టియన్ జుర్గెన్సెన్ థామ్సన్ ప్రతిపాదించిన రాతి-కంచు-ఇనుప అనే మూడు యుగాల వర్గీకరణలో రెండవది కంచుయుగం.
రాగిని కరిగించి, దానికి తగరం, ఆర్సెనిక్ లేదా ఇతర లోహాలను కలిపి కంచును తయారు చేయడం గాని. ఇతర ప్రాంతాలలో తయారైన ఉత్పత్తిని కొనుగోలు చేయడం గానీ చేసిన కాలాన్ని కంచుయుగంగా భావిస్తారు. ఆ కాలం నాటి ఇతర లోహాల కంటే కంచు దృఢమైనది, మన్నికైనదీ. దీంతో ఆనాటి నాగరికతలు సాంకేతికంగా పైచేయి పొందగలిగాయి.
భూమిలో ఇనుము సమృద్ధిగా లభిస్తున్నప్పటికీ దాని అధిక ద్రవీభవన స్థానం - 1,538 ° సెం (2,800 ° ఫా) - కారణంగా క్రీ.పూ రెండవ సహస్రాబ్ది చివరి వరకు ఇనుము వాడకం జరగలేదు. తగరం ద్రవీభవన స్థానం బాగా తక్కువ - 231.9 (సెం (449.4 ° ఫా). రాగి కూడా ఇనుము కంటే బాగా తక్కువ ఉష్ణోగ్రత వద్దనే కరుగుతుంది - 1,085 ° సెం (1,985 ° ఫా). క్రీ.పూ 6000 నాటి కొత్త రాతియుగపు బట్టీల ఉష్ణోగ్రత సామర్థ్యం 900 ° సెం (1,650 ° ఫా) కంటే ఎక్కువగానే ఉండేది. రాగి, తగరాలను కరిగించడానికి ఈ బట్టీల సామర్థ్యం సరిపోయేది. రాగి-తగరపు ఖనిజాల లభ్యత తక్కువగా ఉండేది. క్రీ.పూ. మూడవ సహస్రాబ్దిలో కంచు వ్యాపారం ప్రారంభమయ్యే వరకు పశ్చిమ ఆసియాలో తగరపు కంచు లేకపోవడం దీన్ని బలపరుస్తోంది. ప్రపంచవ్యాప్తంగా కొత్త రాతి యుగం తరువాత కంచుయుగం వచ్చింది. ఈ రెండింటి సంధి కాలంలో రాగియుగం వచ్చింది. ఇనుప యుగం సాధారణంగా కంచుయుగాన్ని అనుసరించినప్పటికీ, కొన్ని ప్రాంతాలలో (ఉప-సహారన్ ఆఫ్రికా వంటి చోట్ల) ఇనుప యుగం క్రీ.పూ 2500 లోనే ప్రారంభమైంది.
కంచుయుగ నాగరికతల్లో రాయడం మొదలవడం విభిన్న కాలాల్లో జరిగింది. పురావస్తు ఆధారాల ప్రకారం, మెసొపొటేమియా (క్యూనిఫాం స్క్రిప్టు), ఈజిప్టు (హైరోగ్లిఫ్సు) నాగరికతలు మొట్టమొదటి రాత వ్యవస్థలను అభివృద్ధి చేశాయి.
స్థూలంగా కంచును విస్తారంగా ఉపయోగించిన కాలాన్ని కంచుయుగంగా గుర్తించారు. అయితే, కంచు సాంకేతికత పరిచయము, అభివృద్ధీ విశ్వవ్యాప్తంగా ఒకే సమయంలో జరగలేదు. తగరపు కంచు తయారీకి ఒక విశిష్ట ఉత్పత్తి పద్ధతులు అవసరం. ముందుగా తగరాన్ని తవ్వాలి (ముఖ్యంగా కాసిటరైటు అనే ధాతువు రూపంలో). దానిని విడిగా కరిగించి శుద్ధి చెయ్యాలి. తరువాత రాగిని కరిగించి దానికి తగరాన్ని కలిపి కంచును తయారు చేయాలి. కంచుయుగం లోహాలను విస్తారంగా ఉపయోగించిన, లోహాలతో వాణిజ్యం చేసిన కాలం. మొట్టమొదటి తగర-కంచు మిశ్రమం ప్లోస్నిక్ (సెర్బియా) లోని విన్స్కా నాగరికతలో క్రీ.పూ. 5 వ సహస్రాబ్ది మధ్యలో జరిగిందని, ఈ నాగరికత కంచుయుగంలో భాగంగా పరిగణించనప్పటికీ, 2013 నాటి నివేదిక సూచిస్తోంది. దీని కాలనిర్ణయం వివాదాస్పదమైంది.

The Ancient Near East Bronze Age can be divided as following:
The archetypal Bronze Age divisions of the Near East have a well-established triadic clearness of expression. The period dates and phases below are solely applicable to the Near East and thus not applicable universally.
క్రీ.పూ. 18 వ శతాబ్దంలో ఉత్తర అనటోలియాలోని హట్టుసాలో హిట్టైటు సామ్రాజ్యం స్థాపించబడింది. క్రీ.పూ. 14 వ శతాబ్దంలో హిట్టైటు రాజ్యం ఉచ్ఛ స్థాయిలో ఉంది. మధ్య అనటోలియా, నైరుతి సిరియా, ఉగారిటు, ఎగువ మెసొపొటేమియాలు ఇందులో భాగంగా ఉన్నాయి. క్రీ.పూ 1180 తరువాత సముద్రమార్గంలో ప్రజల ఆకస్మిక రాకకు, లెవాంటులో సంభవించిన సాధారణ గందరగోళాలకూ సంబంధం ఉందని భావించారు. తరువాత ఈ రాజ్యం అనేక స్వతంత్ర "నియో-హిట్టైటు" నగర-రాజ్యాలుగా విచ్ఛిన్నమైంది. వీటిలో కొన్ని క్రీ.పూ. 8 వ శతాబ్దం వరకు మనుగడ సాగించాయి.
క్రీ.పూ. రెండవ సహస్రాబ్ది ద్వితీయార్ధంలో పశ్చిమ అనటోలియాలోని అర్జావా రాజ్యం, దక్షిణ అనటోలియా వెంట టర్కీ సరస్సుల ప్రాంతం నుండి ఏజియను తీరం వరకు విస్తరించింది. అర్జావా, న్యూ హిట్టైటు రాజ్యాలకు పశ్చిమాన - కొన్నిసార్లు ప్రత్యర్థిగాను, కొన్నిసార్లు సామంతరాజ్యంగానూ ఉండేది.
క్రీ.పూ 1400 లో పశ్చిమ అనటోలియాలోని రాజ్యాల సమాఖ్య " అసువా లీగు"ను మొదటి తుధాలియా నేతృత్వం లోని హిట్టీయుల చేతిలో ఓడిపోయింది. సాధారణంగా అర్జావాను, దానికి ఉత్తరాన ఉన్న అసువాతో అనుసంధించి చూస్తారు. బహుశా అది సరిహద్దు దేశంగా ఉండి ఉండేది. లేదా అసువా లీగుకే ఇది మరొక పేరు అయి ఉండవచ్చు (కనీసం కొన్ని కాలాల్లో).

ఈజిప్టులో కంచుయుగం ఆదిమ రాజవంశాల కాలంలో (సి. క్రీ.పూ. 3150) ప్రారంభమవుతుంది. ప్రాచీన ఈజిప్టు కంచుయుగం (ఈజిప్టు ప్రారంభ రాజవంశం కాలం అని కూడా పిలువబడింది). c. క్రీ.పూ 3100 లో దిగువ, ఎగువ ఈజిప్టుల ఏకీకరణ జరిగిన వెనువెంటనే మొదలైంది. మొదటి, రెండవ రాజవంశాలను సమైఖ్యపరచడానికి ఈ నిర్ణయం తీసుకొనబడింది. ఇది ఈజిప్టు ప్రోటోడైనస్టికు కాలం (క్రీ.పూ 2686) వరకు లేదా పాత రాజ్యం వరకు కొసాగింది. ఈజిప్టు సమైఖ్యం అయిన తరువాత మొదటి రాజవంశం రాజధాని అబిడోసు నుండి మెంఫిసుకు మార్చబడింది. సమైఖ్య ఈజిప్టును కింగు-గాడు పాలించాడు. అబిడోసు దక్షిణప్రాంతంలో ప్రధాన పవిత్ర భూమిగా మిగిలిపోయింది. ప్రారంభ రాజవంశకాలంలో పురాతన ఈజిప్టు నాగరికత అంశాలైన కళ, వాస్తుశిల్పం, మతం రూపుదిద్దుకున్నాయి. ప్రారంభ కంచుయుగంలో మెంఫిసు ఆ సమయంలో అతిపెద్ద నగరంగా ఉంది.ఈజిప్టు నాగరికత శిఖరాగ్రస్థాయి కొనసాగింది. ఈ నాగరికత క్రీ.పూ. 3 వ సహస్రాబ్దిలో మొట్టమొదటి 3 రాజ్యాల కాలంలో (దిగువ నైలు లోయ, మిడిలు కింగ్డం, న్యూ కింగ్డం)ఉనికిలో ఉన్నట్లు గుర్తించబడింది.
ఈజిప్టు మొదటి ఇంటర్మీడియటు కాలం,  పురాతన ఈజిప్టు చరిత్రలో "చీకటి కాలం" గా వర్ణించబడింది. ఇది పాత రాజ్యం ముగిసిన 100 సంవత్సరాల తరువాత క్రీ.పూ 2181 నుండి 2055 వరకు విస్తరించింది. ఈ కాలంలో ముఖ్యంగా ప్రారంభ కాలానికి చెందిన స్మారక ఆధారాలు తక్కువగా ఉన్నాయి. మొదటి ఇంటర్మీడియటు కాంలంలో ఈజిప్టు పాలన సుమారు రెండు పోటీ శక్తి స్థావరాల మధ్య విభజించబడింది: దిగువ ఈజిప్టులోని హెరాక్లోపోలిసు, ఎగువ ఈజిప్టులోని తీబ్సు. ఈ రెండు రాజ్యాలు చివరికి వివాదంలోకి వస్తాయి. ఉత్తరప్రాంతాన్ని తీబను రాజులు జయించారు. ఫలితంగా 11 వ రాజవంశం రెండవ భాగంలో ఈజిప్టు ఒకే పాలకుడి ఆధ్వర్యంలో తిరిగి పాలించబడింది.

ఈజిప్టు మధ్య సామ్రాజ్యం క్రీ.పూ 2055 - 1650 వరకు కొనసాగింది. ఈ కాలంలో ఈజిప్టు ప్రజాదరణ పొందిన మతంలో ఒసిరిసు అంత్యక్రియల ఆచారం ఆధిపత్యం చెలాయించింది. ఈ కాలం రెండు దశలను కలిగి ఉంది: 11 వ రాజవంశం తేబ్సు రాజధానిగా చేసుకుని పాలించింది. 12 వ  13 వ రాజవంశాలు ఎల్-లిష్టు మీద కేంద్రీకృతమై ఉన్నాయి. ఏకీకృత రాజ్యం గతంలో 11 - 12 వ రాజవంశాలన కొనసాగింది. కాని చరిత్రకారులు ఇప్పుడు కనీసం 13 వ రాజవంశం మధ్య రాజ్యానికి చెందినదిగా భావిస్తారు.
రెండవ మద్యకాల కంచుయుగం కాలంలో మధ్య సామ్రాజ్యం ముగింపు, క్రొత్త రాజ్యం ప్రారంభం మధ్య ప్రాచీన ఈజిప్టు రెండవ సారి గందరగోళానికి గురైంది. ఇది 15 - 16 వ రాజవంశాల ఆధ్వర్యంలో ఉన్న హైక్సోసుకు బాగా ప్రసిద్ది చెందింది. ఈజిప్టులో మొట్టమొదటగా 11 వ రాజవంశంలో హైక్సోసు కనిపించారు. 13 వ రాజవంశంలో వీరు అధికారంలోకి రావడం ప్రారంభించి అవారిసు నియంత్రణలో రెండవ ఇంటర్మీడియటు కాలం నుండి వెలుగులోకి వచ్చారు. 15 వ రాజవంశం నాటికి వారు దిగువ ఈజిప్టును పరిపాలించారు. వీరు 17 వ రాజవంశం చివరిలో బహిష్కరించబడ్డారు.

The New Kingdom of Egypt, also referred to as the Egyptian Empire, lasted from the 16th to the 11th century BC. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period. It was Egypt's most prosperous time and marked the peak of Egypt's power. The later New Kingdom, i.e. the 19th and 20th Dynasties (1292–1069 BC), is also known as the Ramesside period, after the eleven pharaohs that took the name of Ramesses.
Elam was a pre-Iranic ancient civilization located to the east of Mesopotamia. In the Old Elamite period (Middle Bronze Age), Elam consisted of kingdoms on the Iranian Plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a crucial role in the Gutian Empire and especially during the Iranic Achaemenid dynasty that succeeded it.
The Oxus civilization was a Bronze Age Central Asian culture dated to c. 2300–1700 BC and centered on the upper Amu Darya (Oxus). In the Early Bronze Age the culture of the Kopet Dag oases and Altyndepe developed a proto-urban society. This corresponds to level IV at Namazga-Tepe. Altyndepe was a major centre even then. Pottery was wheel-turned. Grapes were grown. The height of this urban development was reached in the Middle Bronze Age c. 2300 BC, corresponding to level V at Namazga-Depe. This Bronze Age culture is called the Bactria–Margiana Archaeological Complex (BMAC).
The Kulli culture, similar to those of the Indus Valley Civilisation, was located in southern Balochistan (Gedrosia) c. 2500–2000 BC. Agriculture was the economical base of this people. At several places dams were found, providing evidence for a highly developed water management system.
In modern scholarship the chronology of the Bronze Age Levant is divided into Early/Proto Syrian; corresponding to the Early Bronze. Old Syrian; corresponding to the Middle Bronze. Middle Syrian; corresponding to the Late Bronze. The term Neo-Syria is used to designate the early Iron Age.
The old Syrian period was dominated by the Eblaite first kingdom, Nagar and the Mariote second kingdom. The Akkadian conquered large areas of the Levant and were followed by the Amorite kingdoms, c. 2000–1600 BC, which arose in Mari, Yamhad, Qatna, Assyria. From the 15th century BC onward, the term Amurru is usually applied to the region extending north of Canaan as far as Kadesh on the Orontes River.
The earliest known Ugarit contact with Egypt (and the first exact dating of Ugaritic civilization) comes from a carnelian bead identified with the Middle Kingdom pharaoh Senusret I, 1971–1926 BC. A stela and a statuette from the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear at what time these monuments got to Ugarit. In the Amarna letters, messages from Ugarit c. 1350 BC written by Ammittamru I, Niqmaddu II, and his queen, were discovered. From the 16th to the 13th century BC, Ugarit remained in constant touch with Egypt and Cyprus (named Alashiya).
The Mitanni was a loosely organized state in northern Syria and south-east Anatolia from c. 1500–1300 BC. Founded by an Indo-Aryan ruling class that governed a predominantly Hurrian population, Mitanni came to be a regional power after the Hittite destruction of Kassite Babylon created a power vacuum in Mesopotamia. At its beginning, Mitanni's major rival was Egypt under the Thutmosids. However, with the ascent of the Hittite empire, Mitanni and Egypt made an alliance to protect their mutual interests from the threat of Hittite domination. At the height of its power, during the 14th century BC, it had outposts centered on its capital, Washukanni, which archaeologists have located on the headwaters of the Khabur River. Eventually, Mitanni succumbed to Hittite, and later Assyrian attacks, and was reduced to a province of the Middle Assyrian Empire.
The Israelites were an ancient Semitic-speaking people of the Ancient Near East who inhabited part of Canaan during the tribal and monarchic periods (15th to 6th centuries BC), and lived in the region in smaller numbers after the fall of the monarchy. The name "Israel" first appears c. 1209 BC, at the end of the Late Bronze Age and the very beginning of the Iron Age, on the Merneptah Stele raised by the Egyptian pharaoh Merneptah.
The Arameans were a Northwest Semitic semi-nomadic and pastoralist people who originated in what is now modern Syria (Biblical Aram) during the Late Bronze Age and the early Iron Age. Large groups migrated to Mesopotamia, where they intermingled with the native Akkadian (Assyrian and Babylonian) population. The Aramaeans never had a unified empire; they were divided into independent kingdoms all across the Near East. After the Bronze Age collapse, their political influence was confined to a number of Syro-Hittite states, which were entirely absorbed into the Neo-Assyrian Empire by the 8th century BC.
The Mesopotamian Bronze Age began about 3500 BC and ended with the Kassite period (c. 1500 BC – c. 1155 BC). The usual tripartite division into an Early, Middle and Late Bronze Age is not used. Instead, a division primarily based on art-historical and historical characteristics is more common.
The cities of the Ancient Near East housed several tens of thousands of people. Ur, Kish, Isin, Larsa and Nippur in the Middle Bronze Age and Babylon, Calah and Assur in the Late Bronze Age similarly had large populations. The Akkadian Empire (2335–2154 BC) became the dominant power in the region, and after its fall the Sumerians enjoyed a renaissance with the Neo-Sumerian Empire. Assyria was extant from as early as the 25th century BC, and became a regional power with the Old Assyrian Empire (c. 2025–1750 BC). The earliest mention of Babylon (then a small administrative town) appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC. The Amorite dynasty established the city-state of Babylon in the 19th century BC. Over 100 years later, it briefly took over the other city-states and formed the short lived First Babylonian Empire during what is also called the Old Babylonian Period. Akkad, Assyria and Babylonia all used the written East Semitic Akkadian language for official use and as a spoken language. By that time, the Sumerian language was no longer spoken, but was still in religious use in Assyria and Babylonia, and would remain so until the 1st century AD. The Akkadian and Sumerian traditions played a major role in later Assyrian and Babylonian culture, even though Babylonia (unlike the more militarily powerful Assyria) itself was founded by non-native Amorites and often ruled by other non-indigenous peoples, such as Kassites, Arameans and Chaldeans, as well as its Assyrian neighbours.

The Bactria–Margiana Archaeological Complex (BMAC), also known as the Oxus civilization was a Bronze Age civilization in Central Asia, dated to c. 2400–1600 BC, located in present-day northern Afghanistan, eastern Turkmenistan, southern Uzbekistan and western Tajikistan, centred on the upper Amu Darya (Oxus River). Its sites were discovered and named by the Soviet archaeologist Viktor Sarianidi (1976). Bactria was the Greek name for the area of Bactra (modern Balkh), in what is now northern Afghanistan, and Margiana was the Greek name for the Persian satrapy of Marguš, the capital of which was Merv, in modern-day southeastern Turkmenistan.
According to recent studies  the BMAC was not a primary contributor to later South-Asian genetics.

The Altai Mountains in what is now southern Russia and central Mongolia have been identified as the point of origin of a cultural enigma termed the Seima-Turbino Phenomenon. It is conjectured that changes in climate in this region around 2000 BC and the ensuing ecological, economic and political changes triggered a rapid and massive migration westward into northeast Europe, eastward into China and southward into Vietnam and Thailand  across a frontier of some 4,000 miles. This migration took place in just five to six generations and led to peoples from Finland in the west to Thailand in the east employing the same metal working technology and, in some areas, horse breeding and riding. It is further conjectured that the same migrations spread the Uralic group of languages across Europe and Asia: some 39 languages of this group are still extant, including Hungarian, Finnish and Estonian. However, recent genetic testings of sites in south Siberia and Kazakhstan (Andronovo horizon) would rather support a spreading of the bronze technology via Indo-European migrations eastwards, as this technology was well known for quite a while in western regions.
The term "Bronze Age" has been transferred to the archaeology of China from that of Western Eurasia, and there is no consensus or universally used convention delimiting the "Bronze Age" in the context of Chinese prehistory.
By convention, the "Early Bronze Age" in China is sometimes taken as equivalent to the "Shang dynasty" period of Chinese prehistory (16th to 11th centuries BC), and the "Later Bronze Age" as equivalent to the "Zhou dynasty" period (11th to 3rd centuries BC, from the 5th century also dubbed "Iron Age"), although there is an argument to be made that the "Bronze Age" proper never ended in China, as there is no recognizable transition to an "Iron Age". Significantly, together with the jade art that precedes it, bronze was seen as a "fine" material for ritual art when compared with iron or stone, stone only becoming popular for tombs in the Han on probable Indian influence (replacing wooden temple in that instance).
Bronze metallurgy in China originated in what is referred to as the Erlitou (Wade–Giles: Erh-li-t'ou) period, which some historians argue places it within the range of dates controlled by the Shang dynasty. Others believe the Erlitou sites belong to the preceding Xia (Wade–Giles: Hsia) dynasty. The U.S. National Gallery of Art defines the Chinese Bronze Age as the "period between about 2000 BC and 771 BC," a period that begins with the Erlitou culture and ends abruptly with the disintegration of Western Zhou rule.
The widespread use of bronze in Chinese metallurgy and culture dates to significantly later, probably due to Western influence. While there may be reason to believe that bronzework developed inside China separately from outside influence, the discovery of Europoid mummies in Xinjiang suggests a possible route of transmission from the West beginning in the early second millennium BC. This is, however, still just speculation since there is a lack of direct evidence. A few human mummies alone cannot provide sufficient explanation of metallurgy transmission. Furthermore, the oldest bronze objects found in China so far were discovered at the Majiayao site in Gansu rather than Xinjiang
The Shang dynasty (also known as the Yin dynasty) of the Yellow River Valley rose to power after the Xia dynasty around 1600 BC. While some direct information about the Shang dynasty comes from Shang-era inscriptions on bronze artifacts, most comes from oracle bones – turtle shells, cattle scapulae, or other bones – which bear glyphs that form the first significant corpus of recorded Chinese characters.
Iron is found from the Zhou dynasty, but its use is minimal. Chinese literature dating to the 6th century BC attests knowledge of iron smelting, yet bronze continues to occupy the seat of significance in the archaeological and historical record for some time after this. Historian W.C. White argues that iron did not supplant bronze "at any period before the end of the Zhou dynasty (256 BC)" and that bronze vessels make up the majority of metal vessels all the way through the Later Han period, or to 221 BC [sic?].
The Chinese bronze artifacts generally are either utilitarian, like spear points or adze heads, or "ritual bronzes", which are more elaborate versions in precious materials of everyday vessels, as well as tools and weapons. Examples are the numerous large sacrificial tripods known as dings in Chinese; there are many other distinct shapes. Surviving identified Chinese ritual bronzes tend to be highly decorated, often with the taotie motif, which involves highly stylized animal faces. These appear in three main motif types: those of demons, of symbolic animals, and of abstract symbols. Many large bronzes also bear cast inscriptions that are the great bulk of the surviving body of early Chinese writing and have helped historians and archaeologists piece together the history of China, especially during the Zhou dynasty (1046–256 BC).
The bronzes of the Western Zhou dynasty document large portions of history not found in the extant texts that were often composed by persons of varying rank and possibly even social class. Further, the medium of cast bronze lends the record they preserve a permanence not enjoyed by manuscripts. These inscriptions can commonly be subdivided into four parts: a reference to the date and place, the naming of the event commemorated, the list of gifts given to the artisan in exchange for the bronze, and a dedication. The relative points of reference these vessels provide have enabled historians to place most of the vessels within a certain time frame of the Western Zhou period, allowing them to trace the evolution of the vessels and the events they record.
|Korean Bronze Age|
The beginning of the Bronze Age on the peninsula is around 1000–800 BC. Although the Korean Bronze Age culture derives from the Liaoning and Manchuria, it exhibits unique typology and styles, especially in ritual objects.
The Mumun pottery period is named after the Korean name for undecorated or plain cooking and storage vessels that form a large part of the pottery assemblage over the entire length of the period, but especially 850–550 BC. The Mumun period is known for the origins of intensive agriculture and complex societies in both the Korean Peninsula and the Japanese Archipelago.
The Middle Mumun pottery period culture of the southern Korean Peninsula gradually adopted bronze production (c. 700–600? BC) after a period when Liaoning-style bronze daggers and other bronze artifacts were exchanged as far as the interior part of the Southern Peninsula (c. 900–700 BC). The bronze daggers lent prestige and authority to the personages who wielded and were buried with them in high-status megalithic burials at south-coastal centres such as the Igeum-dong site. Bronze was an important element in ceremonies and as for mortuary offerings until 100.
|Japanese Bronze Age|
The Japanese archipelago experienced the introduction of bronze during the beginning of the Early Yayoi period (≈300 BC), which saw the introduction of metalworking and agricultural practices brought in by settlers arriving from the continent. Bronze and iron smelting techniques spread to the Japanese archipelago through contact with other ancient East Asian civilizations, particularly immigration and trade from the Korean peninsula and ancient Mainland China. Iron was mainly used for agricultural and other tools, whereas ritual and ceremonial artifacts were mainly made of bronze.

The Bronze Age on the Indian subcontinent began around 3300 BC with the beginning of the Indus Valley civilization. Inhabitants of the Indus Valley, the Harappans, developed new techniques in metallurgy and produced copper, bronze, lead and tin. The Late Harappan culture, which dates from 1900–1400 BC, overlapped the transition from the Bronze Age to the Iron Age; thus it is difficult to date this transition accurately. It has been claimed that a 6,000 year old copper amulet manufactured in Mehrgarh in the shape of wheel spoke is the earliest example of lost wax casting in the world.
In Ban Chiang, Thailand, (Southeast Asia) bronze artifacts have been discovered dating to 2100 BC. However, according to the radiocarbon dating on the human and pig bones in Ban Chiang, some scholars propose that the initial Bronze Age in Ban Chiang was in late 2nd millennium. In Nyaunggan, Burma, bronze tools have been excavated along with ceramics and stone artifacts. Dating is still currently broad (3500–500 BC). Ban Non Wat, excavated by Charles Higham, was a rich site with over 640 graves excavated that gleaned many complex bronze items that may have had social value connected to them.
Ban Chiang, however, is the most thoroughly documented site while having the clearest evidence of metallurgy when it comes to Southeast Asia. With a rough date range of late 3rd millennium BC to the first millennium AD, this site alone has various artifacts such as burial pottery (dating from 2100–1700 BC), fragments of Bronze, copper-base bangles, and much more. What's interesting about this site, however, isn't just the old age of the artifacts but the fact that this technology suggested on-site casting from the very beginning. The on-site casting supports the theory that Bronze was first introduced in Southeast Asia as fully developed which therefore shows that Bronze was actually innovated from a different country. Some scholars believe that the copper-based metallurgy was disseminated from northwest and central China via south and southwest areas such as Guangdong province and Yunnan province and finally into southeast Asia around 1000 BC. Archaeology also suggests that Bronze Age metallurgy may not have been as significant a catalyst in social stratification and warfare in Southeast Asia as in other regions, social distribution shifting away from chiefdom-states to a heterarchical network. Data analyses of sites such as Ban Lum Khao, Ban Na Di, Non Nok Tha, Khok Phanom Di, and Nong Nor have consistently led researchers to conclude that there was no forentrenched hierarchy.
Dating back to the Neolithic Age, the first bronze drum, called the Dong Son drum, were uncovered in and around the Red River Delta regions of Northern Vietnam and Southern China. These relate to the prehistoric Dong Son Culture of Vietnam.[ఉల్లేఖన అవసరం]
Archaeological research in Northern Vietnam indicates an increase in rates of infectious disease following the advent of metallurgy; skeletal fragments in sites dating to the early and mid-Bronze Age evidence a greater proportion of lesions than in sites of earlier periods. There are a few possible implications of this. One is the increase contact with bacterial and/or fungal pathogens due to increased population density and land clearing/ cultivation. The other one is decreased levels of immunocompetence in the Metal age due to changes in diet caused by agriculture. The last is that there may have been an emergence of infectious disease in the Da But period that evolved into a more virulent form in the metal period.

A study in the journal Antiquity published in 2013 reported the discovery of a tin bronze foil from the Pločnik archaeological site securely dated to c. 4650 BC as well as 14 other artefacts from Serbia and Bulgaria dated to before 4000 BC has shown that early tin bronze was more common than previously thought, and developed independently in Europe 1500 years before the first tin bronze alloys in the Near East. The production of complex tin bronzes lasted for c. 500 years in the Balkans. The authors reported that evidence for the production of such complex bronzes disappears at the end of the 5th millennium coinciding with the "collapse of large cultural complexes in north-eastern Bulgaria and Thracein the late fifth millennium BC". Tin bronzes using cassiterite tin would be reintroduced to the area again some 1500 years later.
The Aegean Bronze Age began around 3200 BC, when civilizations first established a far-ranging trade network. This network imported tin and charcoal to Cyprus, where copper was mined and alloyed with the tin to produce bronze. Bronze objects were then exported far and wide, and supported the trade. Isotopic analysis of tin in some Mediterranean bronze artifacts suggests that they may have originated from Great Britain.
Knowledge of navigation was well developed at this time, and reached a peak of skill not exceeded (except perhaps by Polynesian sailors) until 1730 when the invention of the chronometer enabled the precise determination of longitude.
The Minoan civilization based in Knossos on the island of Crete appears to have coordinated and defended its Bronze Age trade. Illyrians are also believed to have roots in the early Bronze Age. Ancient empires valued luxury goods in contrast to staple foods, leading to famine.
Bronze Age collapse theories have described aspects of the end of the Age in this region. At the end of the Bronze Age in the Aegean region, the Mycenaean administration of the regional trade empire followed the decline of Minoan primacy. Several Minoan client states lost much of their population to famine and/or pestilence. This would indicate that the trade network may have failed, preventing the trade that would previously have relieved such famines and prevented illness caused by malnutrition. It is also known that in this era the breadbasket of the Minoan empire, the area north of the Black Sea, also suddenly lost much of its population, and thus probably some capacity to cultivate crops.[ఉల్లేఖన అవసరం]Drought and famine in Anatolia may have also led to the Aegean Collapse by disrupting trade networks, and therefore preventing the Aegean from accessing bronze and luxury goods.
The Aegean Collapse has been attributed to the exhaustion of the Cypriot forests causing the end of the bronze trade. These forests are known to have existed into later times, and experiments have shown that charcoal production on the scale necessary for the bronze production of the late Bronze Age would have exhausted them in less than fifty years.
The Aegean Collapse has also been attributed to the fact that as iron tools became more common, the main justification for the tin trade ended, and that trade network ceased to function as it did formerly. The colonies of the Minoan empire then suffered drought, famine, war, or some combination of those three, and had no access to the distant resources of an empire by which they could easily recover.
The Thera eruption occurred around the Aegean Collapse, 110 km (68 mi) north of Crete. Speculation include a tsunami from Thera (more commonly known today as Santorini) destroyed Cretan cities. A tsunami may have destroyed the Cretan navy in its home harbour, which then lost crucial naval battles; so that in the LMIB/LMII event (c. 1450 BC) the cities of Crete burned and the Mycenaean civilization took over Knossos. If the eruption occurred in the late 17th century BC (as most chronologists now think) then its immediate effects belong to the Middle to Late Bronze Age transition, and not to the end of the Late Bronze Age; but it could have triggered the instability that led to the collapse first of Knossos and then of Bronze Age society overall. One such theory highlights the role of Cretan expertise in administering the empire, post-Thera. If this expertise was concentrated in Crete, then the Mycenaeans may have made political and commercial mistakes in administering the Cretan empire.
Archaeological findings, including some on the island of Thera, suggest that the centre of Minoan Civilization at the time of the eruption was actually on Thera rather than on Crete.[ఉల్లేఖన అవసరం] According to this theory, the catastrophic loss of the political, administrative and economic centre by the eruption as well as the damage wrought by the tsunami to the coastal towns and villages of Crete precipitated the decline of the Minoans. A weakened political entity with a reduced economic and military capability and fabled riches would have then been more vulnerable to human predators. Indeed, the Santorini Eruption is usually dated to c. 1630 BC, while the Mycenaean Greeks first enter the historical record a few decades later, c. 1600 BC. Thus, the later Mycenaean assaults on Crete (c. 1450 BC) and Troy ( c. 1250BC) are revealed as mere continuations of the steady encroachments of the Greeks upon the weakened Minoan world.
In Central Europe, the early Bronze Age Unetice culture (1800–1600 BC) includes numerous smaller groups like the Straubing, Adlerberg and Hatvan cultures. Some very rich burials, such as the one located at Leubingen with grave gifts crafted from gold, point to an increase of social stratification already present in the Unetice culture. All in all, cemeteries of this period are rare and of small size. The Unetice culture is followed by the middle Bronze Age (1600–1200 BC) Tumulus culture, which is characterised by inhumation burials in tumuli (barrows). In the eastern Hungarian Körös tributaries, the early Bronze Age first saw the introduction of the Mako culture, followed by the Otomani and Gyulavarsand cultures.
The late Bronze Age Urnfield culture (1300–700 BC) is characterized by cremation burials. It includes the Lusatian culture in eastern Germany and Poland (1300–500 BC) that continues into the Iron Age. The Central European Bronze Age is followed by the Iron Age Hallstatt culture (700–450 BC).
Important sites include:
The Bronze Age in Central Europe has been described in the chronological schema of German prehistorian Paul Reinecke. He described Bronze A1 (Bz A1) period (2300–2000 BC : triangular daggers, flat axes, stone wrist-guards, flint arrowheads) and Bronze A2 (Bz A2) period (1950–1700 BC : daggers with metal hilt, flanged axes, halberds, pins with perforated spherical heads, solid bracelets) and phases Hallstatt A and B (Ha A and B).
The Apennine culture (also called Italian Bronze Age) is a technology complex of central and southern Italy spanning the Chalcolithic and Bronze Age proper. The Camuni were an ancient people of uncertain origin (according to Pliny the Elder, they were Euganei; according to Strabo, they were Rhaetians) who lived in Val Camonica – in what is now northern Lombardy – during the Iron Age, although human groups of hunters, shepherds and farmers are known to have lived in the area since the Neolithic.
Located in Sardinia and Corsica, the Nuragic civilization lasted from the early Bronze Age (18th century BC) to the 2nd century AD, when the islands were already Romanized. They take their name from the characteristic nuragic towers, which evolved from the pre-existing megalithic culture, which built dolmens and menhirs. The nuraghe towers are unanimously considered the best preserved and largest megalithic remains in Europe. Their effective use is still debated: some scholars considered them as monumental tombs, others as Houses of the Giants, other as fortresses, ovens for metal fusion, prisons or, finally, temples for a solar cult. Around the end of the 3rd millennium BC, Sardinia exported towards Sicily a Culture that built small dolmens, trilithic or polygonal shaped, that served as tombs as it has been ascertained in the Sicilian dolmen of “Cava dei Servi”. From this region they reached Malta island and other countries of Mediterranean basin.
The Terramare was an early Indo-European civilization in the area of what is now Pianura Padana (northern Italy) before the arrival of the Celts, and in other parts of Europe. They lived in square villages of wooden stilt houses. These villages were built on land, but generally near a stream, with roads that crossed each other at right angles. The whole complex denoted the nature of a fortified settlement. Terramare were widespread in the Pianura Padana (specially along the Panaro river, between Modena and Bologna) and in the rest of Europe. The civilization developed in the Middle and Late Bronze Age, between the 17th and the 13th centuries BC.
The Castellieri culture developed in Istria during the Middle Bronze Age. It lasted for more than a millennium, from the 15th century BC until the Roman conquest in the 3rd century BC. It takes its name from the fortified boroughs (Castellieri, Friulian: cjastelir) that characterized the culture.
The Canegrate culture developed from the mid-Bronze Age (13th century BC) until the Iron Age in the Pianura Padana, in what are now western Lombardy, eastern Piedmont and Ticino. It takes its name from the township of Canegrate where, in the 20th century, some fifty tombs with ceramics and metal objects were found. The Canegrate culture migrated from the northwest part of the Alps and descended to Pianura Padana from the Swiss Alps passes and the Ticino.
The Golasecca culture developed starting from the late Bronze Age in the Po plain. It takes its name from Golasecca, a locality next to the Ticino where, in the early 19th century, abbot Giovanni Battista Giani excavated its first findings (some fifty tombs with ceramics and metal objects). Remains of the Golasecca culture span an area of c. 20,000 square kilometers south to the Alps, between the Po, Sesia and Serio rivers, dating from the 9th to the 4th century BC.
The Atlantic Bronze Age is a cultural complex of the period of approximately 1300–700 BC that includes different cultures in Portugal, Andalusia, Galicia and the British Isles. It is marked by economic and cultural exchange. Commercial contacts extend to Denmark and the Mediterranean. The Atlantic Bronze Age was defined by a number of distinct regional centres of metal production, unified by a regular maritime exchange of some of their products.
In Great Britain, the Bronze Age is considered to have been the period from around 2100 to 750 BC. Migration brought new people to the islands from the continent. Recent tooth enamel isotope research on bodies found in early Bronze Age graves around Stonehenge indicate that at least some of the migrants came from the area of modern Switzerland. Another example site is Must Farm, near Whittlesey, which has recently been host to the most complete Bronze Age wheel ever to be found. The Beaker culture displayed different behaviours from the earlier Neolithic people, and cultural change was significant. Integration is thought to have been peaceful, as many of the early henge sites were seemingly adopted by the newcomers. The rich Wessex culture developed in southern Britain at this time. Additionally, the climate was deteriorating; where once the weather was warm and dry it became much wetter as the Bronze Age continued, forcing the population away from easily defended sites in the hills and into the fertile valleys. Large livestock farms developed in the lowlands and appear to have contributed to economic growth and inspired increasing forest clearances. The Deverel-Rimbury culture began to emerge in the second half of the Middle Bronze Age ( c. 1400–1100 BC) to exploit these conditions. Devon and Cornwall were major sources of tin for much of western Europe and copper was extracted from sites such as the Great Orme mine in northern Wales. Social groups appear to have been tribal but with growing complexity and hierarchies becoming apparent.
The burial of the dead (which, until this period, had usually been communal) became more individual. For example, whereas in the Neolithic a large chambered cairn or long barrow housed the dead, Early Bronze Age people buried their dead in individual barrows (also commonly known and marked on modern British Ordnance Survey maps as tumuli), or sometimes in cists covered with cairns.
The greatest quantities of bronze objects in England were discovered in East Cambridgeshire, where the most important finds were recovered in Isleham (more than 6500 pieces). Alloying of copper with zinc or tin to make brass or bronze was practised soon after the discovery of copper itself. One copper mine at Great Orme in North Wales, extended to a depth of 70 meters. At Alderley Edge in Cheshire, carbon dates have established mining at around 2280 to 1890 BC (at 95% probability). The earliest identified metalworking site (Sigwells, Somerset) is much later, dated by Globular Urn style pottery to approximately the 12th century BC. The identifiable sherds from over 500 mould fragments included a perfect fit of the hilt of a sword in the Wilburton style held in Somerset County Museum.
The Bronze Age in Ireland commenced around 2000 BC, when copper was alloyed with tin and used to manufacture Ballybeg type flat axes and associated metalwork. The preceding period is known as the Copper Age and is characterised by the production of flat axes, daggers, halberds and awls in copper. The period is divided into three phases: Early Bronze Age (2000–1500 BC), Middle Bronze Age (1500–1200 BC), and Late Bronze Age (1200–c. 500 BC). Ireland is also known for a relatively large number of Early Bronze Age burials.
One of the characteristic types of artifact of the Early Bronze Age in Ireland is the flat axe. There are five main types of flat axes: Lough Ravel (c. 2200 BC), Ballybeg (c. 2000 BC), Killaha (c. 2000 BC), Ballyvalley (c. 2000–1600 BC), Derryniggin (c. 1600 BC), and a number of metal ingots in the shape of axes.
The Bronze Age in Northern Europe spans the entire 2nd millennium BC (Unetice culture, Urnfield culture, Tumulus culture, Terramare culture, Lusatian culture) lasting until c. 600 BC. The Northern Bronze Age was both a period and a Bronze Age culture in Scandinavian pre-history, c. 1700–500 BC, with sites that reached as far east as Estonia. Succeeding the Late Neolithic culture, its ethnic and linguistic affinities are unknown in the absence of written sources. It is followed by the Pre-Roman Iron Age.
Even though Northern European Bronze Age cultures were relatively late, and came into existence via trade, sites present rich and well-preserved objects made of wool, wood and imported Central European bronze and gold. Many rock carvings depict ships, and the large stone burial monuments known as stone ships suggest that shipping played an important role. Thousands of rock carvings depict ships, most probably representing sewn plank built canoes for warfare, fishing and trade. These may have a history as far back as the neolithic period and continue into the Pre-Roman Iron Age, as shown by the Hjortspring boat. There are many mounds and rock carving sites from the period. Numerous artifacts of bronze and gold are found. No written language existed in the Nordic countries during the Bronze Age. The rock carvings have been dated through comparison with depicted artifacts.
Arsenical bronze artifacts of the Maykop culture in the North Caucasus have been dated around the 4th millennium BC. This innovation resulted in the circulation of arsenical bronze technology over southern and eastern Europe.

The Yamnaya culture is a Late Copper Age/Early Bronze Age culture of the Southern Bug/Dniester/Ural region (the Pontic steppe), dating to the 36th–23rd centuries BC. The name also appears in English as Pit-Grave Culture or Ochre-Grave Culture. The Catacomb culture, c. 2800–2200 BC, comprises several related Early Bronze Age cultures occupying what is presently Russia and Ukraine. The Srubna culture was a Late Bronze Age (18th–12th centuries BC) culture. It is a successor to the Yamnaya and the Poltavka culture.
Iron and copper smelting appeared around the same time in most parts of Africa. As such, most African civilizations outside of Egypt did not experience a distinct Bronze Age. Evidence for iron smelting appears earlier or at the same time as copper smelting in Nigeria c. 900–800 BC, Rwanda and Burundi c. 700–500 BC and Tanzania c. 300 BC.
There is a longstanding debate about whether the development of both copper and iron metallurgy were independently developed in sub-Saharan Africa or were introduced from the outside across the Sahara Desert from North Africa or from the Indian Ocean. Evidence for theories of independent development and for outside introduction are scarce and subject to active scholarly debate. Scholars have suggested that both the relative dearth of archeological research in sub-Saharan Africa as well as long standing prejudices have limited or biased our understanding of pre-historic metallurgy on the continent. One scholar characterized the state of historical knowledge as such: “To say that the history of metallurgy in sub-Saharan Africa is complicated is perhaps an understatement.”
The Bronze Age in Nubia, started as early as 2300 BC. Copper smelting was introduced by Egyptians to the Nubian city of Meroë, in modern-day Sudan, around 2600 BC. A furnace for bronze casting has been found in Kerma that is dated to 2300–1900 BC.
Copper smelting took place in West Africa prior to the appearance of iron smelting in the region. Evidence for copper smelting furnaces was found near Agadez, Niger that has been dated as early as 2200 BC. However, evidence for copper production in this region before 1000 BC is debated. Evidence of copper mining and smelting has been found at Akjoujt, Mauretania that suggests small scale production c. 800 to 400 BC.
The Moche civilization of South America independently discovered and developed bronze smelting. Bronze technology was developed further by the Incas and used widely both for utilitarian objects and sculpture. A later appearance of limited bronze smelting in West Mexico (see Metallurgy in pre-Columbian Mesoamerica) suggests either contact of that region with Andean cultures or separate discovery of the technology. The Calchaquí people of Northwest Argentina had bronze technology.

However, the Maykop culture only had arsenical bronze. Other regions developed bronze and its associated technology at different periods.

Quote: "First coined in 1881 by the French Egyptologist G. Maspero (1896), the somewhat misleading term "Sea Peoples" encompasses the ethnonyms Lukka, Sherden, Shekelesh, Teresh, Eqwesh, Denyen, Sikil / Tjekker, Weshesh, and Peleset (Philistines). [Footnote: The modern term "Sea Peoples" refers to peoples that appear in several New Kingdom Egyptian texts as originating from "islands" (tables 1–2; Adams and Cohen, this volume; see, e.g., Drews 1993, 57 for a summary). The use of quotation marks in association with the term "Sea Peoples" in our title is intended to draw attention to the problematic nature of this commonly used term. It is noteworthy that the designation "of the sea" appears only in relation to the Sherden, Shekelesh, and Eqwesh. Subsequently, this term was applied somewhat indiscriminately to several additional ethnonyms, including the Philistines, who are portrayed in their earliest appearance as invaders from the north during the reigns of Merenptah and Ramesses Ill (see, e.g., Sandars 1978; Redford 1992, 243, n. 14; for a recent review of the primary and secondary literature, see Woudhuizen 2006). Hencefore the term Sea Peoples will appear without quotation marks.]"
- The End of the Bronze Age: Changes in Warfare and the Catastrophe Ca. 1200 B.C., Robert Drews, pp. 48–61 Quote: "The thesis that a great "migration of the Sea Peoples" occurred ca. 1200 B.C. is supposedly based on Egyptian inscriptions, one from the reign of Merneptah and another from the reign of Ramesses III. Yet in the inscriptions themselves such a migration nowhere appears. After reviewing what the Egyptian texts have to say about 'the sea peoples', one Egyptologist (Wolfgang Helck) recently remarked that although some things are unclear, "eins ist aber sicher: Nach den agyptischen Texten haben wir es nicht mit einer 'Volkerwanderung' zu tun." Thus the migration hypothesis is based not on the inscriptions themselves but on their interpretation."
