Iron Age is the period when iron became the main material for tools and weapons. It began around 1200 BCE in many parts of the world. Iron was stronger and more available than bronze.

Iron tools helped improve farming and building. Societies grew larger, and powerful kingdoms and empires developed in regions such as Africa, Europe, and Asia. Weapons made of iron were also used in conflicts and defense.

Examples of Iron Age cultures include early African iron-working societies and groups in Europe and Asia. This period followed the Bronze Age and led to more advanced societies.
