When Did the Bronze Age Begin?

The Bronze Age, a major period of technological advancement, began around 3300 BC in the ancient Near East (Mesopotamia, Egypt, and the Indus Valley) when metalworkers discovered that adding tin to copper produced bronze — an alloy significantly harder and more durable than either metal alone. Bronze tools and weapons gave societies that mastered the technology a major advantage. The era saw the rise of cities, writing systems, long-distance trade networks (to secure tin, which is geographically scarce), and the first empires. The Bronze Age ended differently across regions: in the Near East, it collapsed around 1200 BC in a widespread crisis involving invasions, droughts, and trade disruption; in China, it transitioned to the Iron Age around 600 BC.
