How many centuries ago did the Iron Age begin?

The Iron Age began in the 12th century BC. That is, it turns out that it began 32 centuries ago. The arrival of the Iron Age marked the beginning of the processing of a new metal – iron. The Hittites were the first to master iron processing, followed by the Assyrians and Philistines. Then iron tools of labor spread among other peoples. This became the reason for the denouement of bloody wars, which caused the death of many ancient civilizations.
