The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention, and the mere presence of cast or wrought iron is not sufficient to represent an Iron Age culture; rather, the term "Iron Age" implies that the production of carbon steel has been perfected to the point where mass production of tools and weapons superior to their bronze equivalents become possible.
In the Ancient Near East, this transition takes place in the wake of the so-called Bronze Age collapse, in the 12th century BC. The technology soon spreads throughout the Mediterranean region and to South Asia.
Its further spread to Central Asia, Eastern and Central Europe is somewhat delayed, and Northern Europe is reached still later, by about 500 BC.
