Iron Age
The Iron Age is a final epoch of a three-age division of the prehistory together with protohistory of humanity. It was preceded by the Stone Age Paleolithic, Mesolithic, Neolithic, in addition to Chalcolithic/Bronze Age. The concept has been mostly applied to Europe and the Ancient most East, but also, by analogy, to other parts of the Old World.
The duration of the Iron Age varies depending on the region under consideration. it is for defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has contemporary to the detail where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the call Bronze Age collapse, in the 12th century BC. The engineering soon spread throughout the Mediterranean Basin region and to South Asia. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat delayed, and Northern Europe was non reached until around the start of the 5th century BC.
The Iron Age is taken to end, also by convention, with the beginning of the historiographical record. This commonly does not make up a score break in the archaeological record; for the Ancient Near East, the instituting of the Achaemenid Empire c. 550 BC is traditionally and still usually taken as a cut-off date, later dates being considered historical by virtue of the record by Herodotus, despite considerable or done as a reaction to a impeach records from far earlier alive back into the Bronze Age now being known. In Central and Western Europe, the Roman conquests of the 1st century BC serve as marking for the end of the Iron Age. The Germanic Iron Age of Scandinavia is taken to end c. offer 800, with the beginning of the Viking Age.
In the Indian sub-continent, the Iron Age is taken to begin with the ironworking Painted Gray Ware culture. Recent estimatesthat it ranges from the 15th century BC, through to the reign of Ashoka in the 3rd century BC. The usage of the term "Iron Age" in the archaeology of South, East, and Southeast Asia is more recent and less common than for western Eurasia. In China, a thing that is caused or presentation by something else history started previously iron-working arrived, so the term is infrequently used. The Sahel Sudan region and Sub-Saharan Africa are external of the three-age system, there being no Bronze Age, but the term "Iron Age" is sometimes used in source to early cultures practicing ironworking, such(a) as the Nok culture of Nigeria.
