Hampshire: History
=== Before the Roman Conquest ===
The region is believed to have been continuously occupied since the end of the last Ice Age about 12,000 BCE. At that time sea levels were lower and Britain was still attached by a land bridge to the European continent and predominantly covered with deciduous woodland. The first inhabitants were Mesolithic hunter-gatherers. The majority of the population would have been concentrated around the river valleys. Over several thousand years the climate became progressively warmer and sea levels rose; the English Channel, which started out as a river, was a major inlet by 8000 BCE, although Britain was still connected to Europe by a land bridge across the North Sea until 6500 BCE. Notable sites from this period include Bouldnor Cliff.
Agriculture was being practised in southern Britain by 4000 BCE and with it a Neolithic culture. Some deforestation took place at that time, although during the Bronze Age, beginning in 2200 BCE, it became more widespread and systematic. Hampshire has few monuments to show from those early periods, although nearby Stonehenge was built in several phases at some time between 3100 and 2200 BCE. In the very late Bronze Age fortified hilltop settlements known as hillforts began to appear in large numbers in many parts of Britain including Hampshire, and they became more and more important in the early and middle Iron Age; many of them are still visible in the landscape today and can be visited, notably Danebury Rings, the subject of a major study by archaeologist Barry Cunliffe. By that period the people of Britain predominantly spoke a Celtic language, and their culture shared much in common with the Celts described by classical writers. The town of Bitterne (Byterne in a reference from the late 11th century.) shares the same root as the River Erne, suggesting the name refers to the Iverni.
Hillforts largely declined in importance in the second half of the second century BCE, with many being abandoned. Probably around that period the first recorded invasion of Britain took place, as southern Britain was largely conquered by warrior-elites from Belgic tribes of northeastern Gaul, but whether those two events were linked to the decline of hillforts is unknown. By the time of the Roman conquest the oppidum at Venta Belgarum, modern-day Winchester, was the de facto regional administrative centre; Winchester was, however, of secondary importance to the Roman-style town of Calleva Atrebatum, modern Silchester, built further north by a dominant Belgic polity known as the Atrebates in the 50s BCE. Julius Caesar invaded south-eastern England briefly in 55 and again in 54 BCE, but he never reached Hampshire. Notable sites from this period include Hengistbury Head (now in Dorset), which was a major port. …
