High Quality Content by WIKIPEDIA articles! The British Iron Age is a conventional name in the archaeology of Great Britain referring to the prehistoric and proto-historic phases of the Iron- Age culture of the main island and the smaller islands, typically excluding Ireland. The parallel phase of Irish archaeology is termed the Irish Iron Age, and similarly locally defined Iron Ages exist for many regions of Europe, such as the Danish Iron Age. The Iron Age is not an archaeological horizon of common artifacts, but is rather a locally diverse cultural phase. Whatever is said of the British Iron Age is not necessarily transferable to any other, and vice versa, except for the common preference for the use of iron.The various Iron Ages have no common set of dates. The British Iron Age lasted in theory from the first significant use of iron for tools and weapons in Britain to the Romanization of the southern half of the island. The Romanized culture is termed Roman Britain and is considered to supplant the British Iron Age.
