In archaeology, the Iron Age was the stage in the development of any people in which tools and weapons whose main ingredient was iron were prominent. The adoption of this material often coincided with other changes in society, including differing agricultural practices, religious beliefs and artistic styles.
In history, the Iron Age is the last principal period in the three-age system for classifying prehistoric societies, preceded by the Bronze Age. Its date and context vary depending on the country or geographical region.
No firm ending date is set for the Iron Age in any particular society; there is simply a point where archaeology becomes less important than surviving history and traditions. Iron alloys remain popular as the steels in most metallic objects.
