The Bronze Age was when people made tools and weapons from bronze, a copper-tin alloy, about 3300–1200 BC in the Near East.
See it on the History map →What happened
Mixing about one part tin with nine parts copper makes a metal much harder than copper alone. Tin was rare, found in places like Afghanistan, Anatolia and Cornwall, so bronze required long-distance trade. The Uluburun shipwreck off Turkey, about 1300 BC, carried 10 tons of copper and 1 ton of tin, the right mix. Bronze swords, armor and chariots equipped Egypt, the Hittites, Mycenaean Greece and Shang China.
Why it matters
Controlling metal and its trade routes concentrated wealth and military power, helping create the first kingdoms, empires and international diplomacy. The era ended in a collapse around 1200 BC.
How we know
Metal objects and their chemistry, excavated mines and workshops, shipwrecks like Uluburun, and texts such as the Amarna letters between kings. Danish curator Christian Thomsen published the Stone–Bronze–Iron scheme in 1836.
Still debated
Where much Bronze Age tin came from is still being traced through chemical isotopes, and dates vary widely by region: China's Bronze Age began around 2000 BC.

Connections (5)
▸First stone tools began the toolmaking that led to Bronze AgeMostly agreed
The connection
For over 3 million years humans and their ancestors made tools from stone, bone and wood, steadily refining them. Bronze Age metalworking built on that long tradition of shaping hard materials, plus later discoveries: pottery kilns and, from about 5000 BC, copper smelting, which supplied the high heat and know-how needed to alloy metals.
When and how
From Lomekwi, Kenya, about 3.3 million years ago, to the Near East, where copper smelting began about 5000 BC and bronze about 3300 BC.
How sure are we?
The archaeological sequence of tool types; this is a long-term trend, not a single cause-and-effect link.
Debates and open questions
Stone tools stayed in everyday use well into the Bronze Age, and how metal knowledge spread between regions is still being traced.
▸Sumer and Mesopotamia: the first cities was an early center of the Bronze AgeMostly agreed
The connection
Mesopotamia had no metal ore of its own, but its wealthy cities imported copper from Oman and Anatolia and tin from as far as Afghanistan. Sumerian smiths made bronze weapons, tools and fine metalwork, such as the treasures of Ur's royal tombs about 2600 BC. Demand for metal helped build long-distance trade.
When and how
Southern Mesopotamia, about 3000–2000 BC; trade partners included Magan (Oman), Dilmun (Bahrain) and lands farther east.
How sure are we?
Bronze objects from Ur and other cities, chemical analysis of their metal, and tablets recording copper and tin trade.
Debates and open questions
Arsenic bronze and early tin bronze appear as early or earlier in Anatolia, Iran and the Balkans, so Sumer was a leader, not clearly the inventor.
▸Bronze Age flourished in China under Shang dynastyMostly agreed
The connection
Bronze, an alloy of copper and tin, was in use in China by about 2000 BC. Under the Shang it reached a peak: workshops cast huge, intricately decorated ritual vessels and weapons in clay piece-molds. Controlling copper and tin mines and skilled casters was a source of royal power, and bronze vessels marked rank in life and burial.
When and how
The Yellow River valley, especially Zhengzhou and Anyang, about 1600–1046 BC; earlier bronze casting at Erlitou about 1900–1500 BC.
How sure are we?
Thousands of excavated Shang bronzes, including the Houmuwu cauldron, 832 kg (1,830 lb); casting workshops and mold fragments found at Anyang.
Debates and open questions
Whether bronze-making reached China from the west or developed largely on its own is debated; the piece-mold casting method was distinctly Chinese.
▸Trojan War is set at the end of Bronze AgeLegend & tradition
The connection
Homer's heroes fight with bronze swords and spears, ride chariots and serve kings in rich palaces, details that fit the late Bronze Age Mycenaean world of about 1600–1100 BC. Homer composed centuries later, in the Iron Age, so his poems mix genuine Bronze Age memories, such as the boar's-tusk helmet, with later customs.
When and how
Traditional date about 1184 BC (an ancient Greek calculation); Troy's destruction layers date about 1300–1180 BC; Homer composed about 750–700 BC.
How sure are we?
Boar's-tusk helmets described by Homer are found in Mycenaean graves; Hittite texts mention Wilusa and Ahhiyawa; but no text confirms the war itself.
Debates and open questions
How much real Bronze Age memory survived some 500 years of oral storytelling, and whether any actual war is remembered, is debated.
▸Bronze Age ended in Bronze Age collapseWell documented
The connection
Bronze required copper, much of it from Cyprus, and tin, often from as far as Central Asia, so Bronze Age kingdoms depended on long trade routes and palace-run economies. That interdependence was a weakness: when drought, earthquakes, raids and revolts struck around 1200 BC, the network unraveled, and the palaces fell with it.
When and how
The eastern Mediterranean and Near East, from Greece to Syria, about 1200–1150 BC.
How we know
The Uluburun shipwreck (about 1300 BC), carrying 10 tonnes of copper and 1 tonne of tin, shows the trade; destruction layers mark its end.
Debates and open questions
Whether the breakdown of the tin trade helped cause the collapse or was only a result of it is debated.
