Roman Britain
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 AD43 to AD410.
Britain was invaded by Julius Caesar in 55 and 54BC 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 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 conquest of Britain continued under command of Gnaeus Julius Agricola, who expanded the Roman Empire as far as Caledonia. In mid-84 AD, Agricola faced the armies of the Caledonians, led by Calgacus, at the Battle of Mons Graupius. Battle casualties were estimated by Tacitus to be upwards of 10,000 on the Caledonian side and about 360 on the Roman side. The bloodbath at Mons Graupius concluded the forty-year conquest of Britain, a period that possibly saw between 100,000 and 250,000 Britons killed. In the context of pre-industrial warfare and of a total population of Britain of, these are very high figures.
Under the 2nd-century emperors Hadrian and Antoninus Pius, two walls were built to defend the Roman province from the Caledonians, Hadrian’s Wall and the Antonine Wall, the first of stone and the second largely of turf. The first is the better preserved. Around 197 AD, the Severan Reforms divided Britain into two provinces: Britannia Superior and Britannia Inferior. In the early fourth century, Britannia was divided into four provinces under the direction of a vicarius, who administered the, and who was himself under the overall authority of the praetorian prefecture of the Gallic region, based at Trier. A fifth province, Valentia, is attested in the later 4th century. For much of the later period of the Roman occupation, Britannia was subject to barbarian invasions and often came under the control of imperial usurpers and imperial pretenders. The final Roman withdrawal from Britain occurred around 410; the native kingdoms are considered to have formed Sub-Roman Britain after that.
Following the conquest of the Britons, a distinctive Romano-British culture emerged as the Romans introduced improved agriculture, urban planning, industrial production, and architecture. The Roman goddess Britannia became the female personification of Britain. After the initial invasions, Roman historians generally only mention Britain in passing. Thus, most present knowledge derives from archaeological investigations and occasional epigraphic evidence lauding the Britannic achievements of an emperor. Roman citizens settled in Britain from many parts of the Empire.
History
Early contact
Britain was known to the Classical world. The Greeks, the Phoenicians and the Carthaginians traded for Cornish tin in the 4th century BC. The Greeks referred to the Cassiterides, or "tin islands", and placed them near the west coast of Europe. The Carthaginian sailor Himilco is said to have visited the island in the 6th or 5th century BC and the Greek explorer Pytheas in the 4th. It was regarded as a place of mystery, with some writers refusing to believe it existed.The first direct Roman contact was when Julius Caesar undertook two expeditions in 55 and 54 BC, as part of his conquest of Gaul, believing the Britons were helping the Gallic resistance. The first expedition was more a reconnaissance than a full invasion and gained a foothold on the coast of Kent but was unable to advance further because of storm damage to the ships and a lack of cavalry. Despite the military failure, it was a political success, with the Roman Senate declaring a 20-day public holiday in Rome to honour the unprecedented achievement of obtaining hostages from Britain and defeating Belgic tribes on returning to the continent.
The second invasion involved a substantially larger force and Caesar coerced or invited many of the native Celtic tribes to pay tribute and give hostages in return for peace. A friendly local king, Mandubracius, was installed, and his rival, Cassivellaunus, was brought to terms. Hostages were taken, but historians disagree over whether any tribute was paid after Caesar returned to Gaul.
Caesar conquered no territory and left no troops behind, but he established clients and brought Britain into Rome's sphere of influence. Augustus planned invasions in 34, 27 and 25 BC, but circumstances were never favourable, and the relationship between Britain and Rome settled into one of diplomacy and trade. Strabo, writing late in Augustus's reign, claimed that taxes on trade brought in more annual revenue than any conquest could. Archaeology shows that there was an increase in imported luxury goods in southeastern Britain. Strabo also mentions British kings who sent embassies to Augustus, and Augustus's own Res Gestae Divi Augusti refers to two British kings he received as refugees. When some of Tiberius's ships were carried to Britain in a storm during his campaigns in Germany in 16 AD, they came back with tales of monsters.
Rome appears to have encouraged a balance of power in southern Britain, supporting two powerful kingdoms: the Catuvellauni, ruled by the descendants of Tasciovanus, and the Atrebates, ruled by the descendants of Commius. This policy was followed until 39 or 40 AD, when Caligula received an exiled member of the Catuvellaunian dynasty and planned an invasion of Britain that collapsed in farcical circumstances before it left Gaul. When Claudius successfully invaded in 43 AD, it was in aid of another fugitive British ruler, Verica of the Atrebates.
Roman invasion
The invasion force in 43 AD was led by Aulus Plautius, but it is unclear how many legions were sent. The Legio II Augusta, commanded by future emperor Vespasian, was the only one directly attested to have taken part. The Legio IX Hispana, the Legio XIV Gemina and the Legio XX Valeria Victrix are known to have served during the Boudican revolt of 60/61, and were probably there since the initial invasion. This is not certain because the Roman army was flexible, with units being moved around whenever necessary. The IX Hispana may have been permanently stationed, with records showing it at Eboracum in 71 and on a building inscription there dated 108, before being destroyed in the east of the Empire, possibly during the Bar Kokhba revolt.The invasion was delayed by a troop mutiny until an imperial freedman persuaded them to overcome their fear of crossing the Ocean and campaigning beyond the limits of the known world. They sailed in three divisions, and probably landed at Richborough in Kent; at least part of the force may have landed near Fishbourne, West Sussex.
The Catuvellauni and their allies were defeated in two battles: the first, assuming a Richborough landing, on the river Medway, the second on the river Thames. One of their leaders, Togodumnus, was killed, but his brother Caratacus survived to continue resistance elsewhere. Plautius halted at the Thames and sent for Claudius, who arrived with reinforcements, including artillery and elephants, for the final march to the Catuvellaunian capital, Camulodunum. Vespasian subdued the southwest, Cogidubnus was set up as a friendly king of several territories, and treaties were made with tribes outside direct Roman control.
Establishment of Roman rule
After capturing the south of the island, the Romans turned their attention to what is now Wales. The Silures, Ordovices and Deceangli remained implacably opposed to the invaders and for the first few decades were the focus of Roman military attention, despite occasional minor revolts among Roman allies like the Brigantes and the Iceni. The Silures were led by Caratacus, and he carried out an effective guerrilla campaign against Governor Publius Ostorius Scapula.In 51, Ostorius lured Caratacus into a set-piece battle and defeated him. The British leader sought refuge among the Brigantes, but their queen, Cartimandua, proved her loyalty by surrendering him to the Romans. He was brought as a captive to Rome, where a dignified speech he made during Claudius's triumph persuaded the emperor to spare his life. The Silures were still not pacified, and Cartimandua's ex-husband Venutius replaced Caratacus as the most prominent leader of British resistance.
On Nero's accession, Roman Britain extended as far north as Lindum. Gaius Suetonius Paulinus, the conqueror of Mauretania, then became governor of Britain, and in 60 and 61 he moved against Mona to settle accounts with Druidism once and for all. Paulinus led his army across the Menai Strait and massacred the Druids and burnt their sacred groves.
While Paulinus was campaigning in Mona, the southeast of Britain rose in revolt under the leadership of Boudica. She was the widow of the recently deceased king of the Iceni, Prasutagus. The Roman historian Tacitus reports that Prasutagus had left a will leaving half his kingdom to Nero in the hope that the remainder would be left untouched. He was wrong. When his will was enforced, Rome responded by violently seizing the tribe's lands in full. Boudica protested. In consequence, Rome punished her and her daughters by flogging and rape. In response, the Iceni, joined by the Trinovantes, destroyed the Roman colony at Camulodunum and routed the part of the IXth Legion that was sent to relieve it.
Paulinus rode to London, the rebels' next target, but concluded it could not be defended. Abandoned, it was destroyed, as was Verulamium. Between seventy and eighty thousand people are said to have been killed in the three cities. But Paulinus regrouped with two of the three legions still available to him, chose a battlefield, and, despite being outnumbered by more than twenty to one, defeated the rebels in the Battle of Watling Street. Boudica died not long afterwards, by self-administered poison or by illness. During this time, the Emperor Nero considered withdrawing Roman forces from Britain altogether.
There was further turmoil in 69, the "Year of the Four Emperors". As civil war raged in Rome, weak governors were unable to control the legions in Britain, and Venutius of the Brigantes seized his chance. The Romans had previously defended Cartimandua against him, but this time were unable to do so. Cartimandua was evacuated, and Venutius was left in control of the north of the country. After Vespasian secured the empire, his first two appointments as governor, Quintus Petillius Cerialis and Sextus Julius Frontinus, took on the task of subduing the Brigantes and Silures respectively. Frontinus extended Roman rule to all of South Wales, and initiated exploitation of the mineral resources, such as the gold mines at Dolaucothi.
In the following years, the Romans conquered more of the island, increasing the size of Roman Britain. Governor Gnaeus Julius Agricola, father-in-law to the historian Tacitus, conquered the Ordovices in 78. With the XX Valeria Victrix legion, Agricola defeated the Caledonians in 84 at the Battle of Mons Graupius, in north-east Scotland. This was the high-water mark of Roman territory in Britain: shortly after his victory, Agricola was recalled from Britain back to Rome and awarded the ornaments of a triumph, before returning to continue as governor. By 87 the decision was taken to abandon most of the land north of the Cheviot Hills allowing for troops to be moved to other frontiers which were under pressure. Tacitus reports Agricola as feeling bitter about this turn of events.
For much of the history of Roman Britain, a large number of soldiers were garrisoned on the island. This required that the emperor station a trusted senior man as governor of the province. As a result, many future emperors served as governors or legates in this province, including Vespasian, Pertinax, and Gordian I.
