The Bronze Age started around c. 3300 BC.
The Bronze Age, a significant period in human history, is characterized by the widespread use of bronze, an alloy of copper and tin, for tools, weapons, and other artifacts. This era marked a transition from the Stone Age and preceded the Iron Age. The start date of the Bronze Age, approximately 3300 BC, is generally accepted, though it's important to remember that its onset varied geographically. Different regions adopted bronze technology at different times, so this date serves as a general marker. The Bronze Age also coincided with the development of complex urban societies and, in some regions, the invention of writing systems. The widespread availability of bronze enabled technological advancements that impacted various aspects of life, including agriculture, warfare, and trade.
