Atrebates in the context of "Noviomagus Reginorum"

Roman Britain was the territory that became the Roman province of Britannia after the Roman conquest of Britain, consisting of a large part of the island of Great Britain. The occupation lasted from AD 43 to AD 410.

Britain was invaded by Julius Caesar in 55 and 54 BC as part of the Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by the Belgae during the British Iron Age and had been aiding Caesar's enemies. The Belgae were the only Celtic tribe to cross the sea into Britain, for to all other Celtic tribes this land was unknown. He received tribute, installed the Celtic king Mandubracius over the Trinovantes, and returned to Gaul. Planned invasions under Augustus were called off in 34, 27, and 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells (musculi) according to Suetonius, perhaps as a symbolic gesture to proclaim Caligula's victory over the sea. Three years later, Claudius directed four legions to invade Britain and restore the exiled king Verica over the Atrebates. The Romans defeated the Catuvellauni, and then organized their conquests as the province of Britain. By 47 AD, the Romans held the lands southeast of the Fosse Way. Control over Wales was delayed by reverses and the effects of Boudica's uprising, but the Romans expanded steadily northwards.

The territory today known as England became inhabited more than 800,000 years ago, as the discovery of stone tools and footprints at Happisburgh in Norfolk have indicated. The earliest evidence for early modern humans in Northwestern Europe, a jawbone discovered in Devon at Kents Cavern in 1927, was re-dated in 2011 to between 41,000 and 44,000 years old. Continuous human habitation in England dates to around 13,000 years ago (see Creswellian), at the end of the Last Glacial Period. The region has numerous remains from the Mesolithic, Neolithic and Bronze Age, such as Stonehenge and Avebury. In the Iron Age, all of Britain south of the Firth of Forth was inhabited by the Celtic people known as the Britons, including some Belgic tribes (e.g. the Atrebates, the Catuvellauni, the Trinovantes, etc.) in the south east. In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century.

The end of Roman rule in Britain facilitated the Anglo-Saxon settlement of Britain, which historians often regard as the origin of England and of the English people. The Anglo-Saxons, a collection of various Germanic peoples, established several kingdoms that became the primary powers in present-day England and parts of southern Scotland. They introduced the Old English language, which largely displaced the previous Brittonic language. The Anglo-Saxons warred with British successor states in western Britain and the Hen Ogledd (Old North; the Brittonic-speaking parts of northern Britain), as well as with each other. Raids by Vikings became frequent after about AD 800, and the Norsemen settled in large parts of what is now England. During this period, several rulers attempted to unite the various Anglo-Saxon kingdoms, an effort that led to the emergence of the Kingdom of England by the 10th century.

The Celtic currency of Britain were the various items and coins used as currency between approximately 200 BC and AD 60. The earliest currency consisted of various forms of iron bars. Coins were first imported in large numbers in around 150 BC and domestic minting began around 100BC. Coin production was largely ended by the Roman conquest of Britain, first by the Claudian invasion of AD 43 and later by the Defeat of Boudica in AD 60 or 61. Cast coins may have been produced for a few more years around Hengistbury Head. Exact dating of coins often changes in the light of new research.

Coin use is usually divided into a core area which covers the home counties as well as parts of Oxfordshire, Northamptonshire and Cambridgeshire. This was surrounded by a periphery of coin using groups some of which, the Corieltauvi, Durotriges, Dobunni and Iceni, appear to have minted their own coinage. The coins in the core area are generally attributed to the Atrebates and Cantii in the areas south of the Thames and the Trinovantes and Catuvellauni to the north.

Verica (early 1st century AD) was a British client king of the Roman Empire in the years preceding the Claudian invasion of 43 AD.

From his coinage, he appears to have been king of the probably Belgic Atrebates tribe and a son of Commius. The distribution of his coins also shows that Verica's kingdom was centred on modern Sussex and east Hampshire, and its capital would have been in or close to what became the Roman Noviomagus Reginorum (modern Chichester). He succeeded his elder brother Eppillus as king in about 15 AD, and may also have reigned over the northern Atrebatic kingdom at Calleva Atrebatum, today called Silchester. He was recognised as rex by Rome and appears to have had friendly trade and diplomatic links with the empire.

Calleva Atrebatum ("Calleva of the Atrebates") was an Iron Age oppidum, the capital of the Atrebates tribe. It then became a walled town in the Roman province of Britannia, at a major crossroads of the roads of southern Britain.

The modern village of Silchester in Hampshire, England, is about a mile (1.6 km) to the west of the site. The village's parish church of St Mary the Virgin is just within the ancient walls. Most of the site lies within the modern civil parish of Silchester, although the amphitheatre is in the adjoining civil parish of Mortimer West End. The whole of the site is within the local authority district of Basingstoke and Deane and the county of Hampshire.
