Approximately, how long did the Bronze Age last?

The Bronze Age is a historical period characterized by the use of bronze, and in some areas proto-writing, and other early features of urban civilization. The Bronze Age marked the first time humans started to work with metal.

In the Middle East and parts of Asia, the Bronze Age lasted from roughly 3300 to 1200 B.C., ending abruptly with the near-simultaneous collapse of several prominent Bronze Age civilizations.

Different human societies entered the Bronze Age at different times. Civilizations in Greece began working with bronze before 3000 B.C., while the British Isles and China entered the Bronze Age much later, around 1900 B.C. and 1600 B.C., respectively.

The Bronze Age was marked by the rise of states or kingdoms—large-scale societies joined under a central government by a powerful ruler. Bronze Age states interacted with each other through trade, warfare, migration and the spread of ideas.

Bronze Age cultures differed in their development of the first writing. According to archaeological evidence, cultures in Mesopotamia (cuneiform script) and Egypt (hieroglyphs) developed the earliest viable writing systems and invention of the wheel.

The overall period is characterized by widespread use of bronze, though the place and time of the introduction and development of bronze technology were not universally synchronous. The Bronze Age ended around 1200 B.C. when humans began to forge an even stronger metal, iron.
