The Bronze Age refers to a time when bronze was the primary metal used to create tools and weapons. It occurred between the Stone Age and the Iron Age and divided into three subsequent time periods: Early Bronze Age, Middle Bronze Age, and Late Bronze Age. It also saw the development of writing systems, pyramids, and ziggurats. The Bronze Age is the earliest period for which we have direct written accounts since the invention of writing coincides with its early beginnings. The Bronze Age is marked by widespread migrations and trade, especially across Europe and in the Mediterranean region, marking the first time humans started to work with metal. This period ranged from 3000 BC - 1200 BC.
