The Bronze Age was a historical period lasting from approximately 3300 to 1200 BC. It was characterized by the use of bronze, the use of writing in some areas, and other features of early urban civilization. The Bronze Age is the middle principal period of the three-age system, between the Stone and Iron Ages. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition.
The Bronze Age is generally considered to have ended with the Late Bronze Age collapse, a time of widespread societal collapse between c. 1200 and 1150 BC. This collapse affected a large area of the Eastern Mediterranean, including North Africa and Southeast Europe, as well as the Near East, in particular Egypt, eastern Libya, the Balkans, the Aegean, Anatolia, and the Caucasus. It was sudden, violent, and culturally disruptive for many Bronze Age civilizations, and it brought a sharp economic decline to regional powers, most notably ushering in the Greek Dark Ages.
An ancient civilization is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere.
Bronze Age cultures were the first to develop writing. According to archaeological evidence, cultures in Mesopotamia, which used cuneiform script, and Egypt, which used hieroglyphs, developed the earliest practical writing systems.
Metal use
Bronze Age civilizations gained a technological advantage due to bronze's harder and more durable properties than other metals available at the time. While terrestrial iron is naturally abundant, the higher temperature required for smelting, 1,250 °C (2,280 °F), in addition to the greater difficulty of working with it, placed it out of reach of common use until the end of the second millennium BC. Tin's lower melting point of 232 °C (450 °F) and copper's moderate melting point of 1,085 °C (1,985 °F) placed both these metals within the capabilities of Neolithic pottery kilns, which date back to 6,000 BC and were able to produce temperatures of at least 900 °C (1,650 °F).
