Iron Age
In the Mesopotamian states of Sumer, Akkad and Assyria, the use of iron reaches far back, to perhaps 3000 BC. One of the earliest smelted iron artifacts known was a dagger with an iron blade found in a Hattic tomb in Anatolia, dating from 2500 BC. The widespread use of iron weapons which replaced bronze weapons rapidly disseminated throughout the Near East (North Africa, southwest Asia) by the beginning of the 1st millennium BC.
