1A prehistoric period that followed the Bronze Age, when weapons and tools came to be made of iron.
2(in Greek and Roman mythology) the last and worst age of the world, a time of wickedness and oppression.
The Iron Age is conventionally taken as beginning in the early 1st millennium BC, but iron-working began with the Hittites in Anatolia in c.1400 BC. Its arrival in Britain was associated with the first Celtic immigrants in about the 6th century BC. In much of Europe it ended at the Roman period, but outside the Roman Empire it continued to the 4th–6th centuries AD
