===Iron Age===
{{see also|Iron Age Britain}}
The earliest iron implement found in Wales is a sword from [[Llyn Fawr]] which overlooks the head of the [[Vale of Neath]], which is thought to date to about 600 BC.{{sfn|Davies|1994|p=19}} [[List of hillforts in Wales|Hillforts]] continued to be built during the British Iron Age. Nearly 600 hillforts are in Wales, over 20% of those found in Britain, examples being [[Pen Dinas]] near [[Aberystwyth]] and [[Tre'r Ceiri]] on the [[Llŷn peninsula]].{{sfn|Davies|2009|p=23}} A particularly significant find from this period was made in 1943 at [[Llyn Cerrig Bach]] on Anglesey when the ground was being prepared for the construction of a [[Royal Air Force]] base. The cache included weapons, shields, [[chariot]]s along with their fittings and harnesses, and slave chains and tools. Many had been deliberately broken and seem to have been [[votive offering]]s.{{sfn|Lynch|1995|pp=249-277}}

A tendency to see the creation of hillforts as evidence of a Celtic invasion that also brought a Celtic language to the Britain has been dealt a blow by recognition that the earliest forts predate the arrival of Iron Age Celtic culture by hundreds of years. The present tendency is to reject the hypothesis of mass invasion in favour of more sporadic migration and a cultural spread of language and ideas, a "culminative Celticity".{{sfn|Davies|2009|p=23}} Then, with the coming of the Celts, there was an agricultural improvement of farming in Britain. This is evident with the then new use of the iron ploughshare, a type of [[Plough]].{{sfn|Jones|2014|p=5}}

====Iron Age Celts====
{{see also|Celts}}
<!--By the time of the [[Roman conquest of Britain|Roman invasion of Britain]] the area of modern Wales had been divided among the tribes of the [[Deceangli]] (north-east), [[Ordovices]] (north-west), [[Demetae]] (south-west), [[Silures]] (south-east), and [[Cornovii (Midlands)|Cornovii]] (east).<ref name="Wales Hist 4–6"/><ref name=":4">{{Cite web |title=Who were the Celts? |url=https://museum.wales/articles/1341/Who-were-the-Celts/ |access-date=2022-09-26 |website=Museum Wales |language=en}}</ref>-->
During the late Bronze Age or early Iron Age in [[Celtic Britain]] ({{circa|800 BC}}) is when modern-day Wales was split into 4 regional [[tribes]]. They were, the [[Ordovices]] ([[Mid Wales]] to [[North West Wales]]), the [[Deceangli]] ([[North East Wales]], [[North Wales]]), the [[Silures]] ([[South East Wales]], Mid Wales) and the [[Demetae]] ([[South West Wales]]).{{sfn|Lynch|2000|page=184}} A second wave ({{circa|500 BC- 200 BC}}) of migration of [[List of ancient Celtic peoples and tribes|Celtic tribes]] from [[Eastern Europe]] emerged in Britain and established stone [[hut]] circle [[Roundhouse (dwelling)#United Kingdom|roundhouse]] settlements within or near the previously inhabited hillfort enclosures. Hut circles were used as dwellings until after the end of Roman rule in Britain. During the Roman occupation, another [[Celtic Briton]] tribe in modern-day Wales was identified as the [[Gangani]] ([[Llŷn Peninsula]], North West Wales), they were a tribe with connections to [[Ireland]].{{sfn|Cunliffe|1978|p=206}}
