Definition: The Iron Age followed the Bronze and Stone Ages as a stage in the material culture of prehistoric human societies that archaeologists distinguish. During the Iron Age, formerly bronze weapons and farm implements were made of iron. Iron tools, stronger and more reliable than bronze (Iron Age Revolution), spurred the growth of agriculture and warfare. The Iron Age did not occur at the same time throughout the world, so one can not refer to a universal Iron Age.
Examples:In Greece the early Iron Age occurred during the Dark Age.
