In order to rebel, of course, one must be a subject – the Maeatae clearly did not consider themselves such. Senecio requested either reinforcements or an Imperial expedition, and Severus chose the latter, despite being 62 years old. Archaeological evidence shows that Senecio had been rebuilding

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 c. 2 million , these are very high figures. Under

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

5290-649: The Danubian provinces . Increasing numbers of hoards of buried coins in Britain at this time indicate that peace was not entirely achieved. Sufficient Roman silver has been found in Scotland to suggest more than ordinary trade, and it is likely that the Romans were reinforcing treaty agreements by paying tribute to their implacable enemies, the Picts . In 175, a large force of Sarmatian cavalry, consisting of 5,500 men, arrived in Britannia, probably to reinforce troops fighting unrecorded uprisings. In 180, Hadrian's Wall

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.

The latter was the new governor of Britannia, and had seemingly won the natives over after their earlier rebellions; he also controlled three legions, making him a potentially significant claimant. His sometime rival Severus promised him the title of Caesar in return for Albinus's support against Pescennius Niger in
8395-430: The final march to the Catuvellaunian capital, Camulodunum ( Colchester ). 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. British archaeologist Richard Hingley said that the Roman conquest of Britain , beginning with Julius Caesar 's expeditions and culminating with the construction of Hadrian's Wall ,
8510-684: 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
8625-521: 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
8740-399: The frontier. He had significant autonomy due in part to the distance from his superiors. The tasks of the vicarius were to control and coordinate the activities of governors; monitor but not interfere with the daily functioning of the Treasury and Crown Estates, which had their own administrative infrastructure; and act as the regional quartermaster-general of the armed forces. In short, as
8855-576: The headwaters and upper valleys of the rivers Lea and the Colne ; both flow south and each is accompanied by a canal. Hertfordshire's undeveloped land is mainly agricultural and much of the county is covered by the Metropolitan green belt . Since 1903, Letchworth has served as the prototype garden city while Stevenage became the first town to expand under post-war Britain 's New Towns Act 1946 ( 9 & 10 Geo. 6 . c. 68). Services have become
8970-573: The island of its garrison, leaving the province defenceless against uprisings by the native Celtic tribes and against invasion by the Picts and Scots . The traditional view is that northern Britain descended into anarchy during Albinus's absence. Cassius Dio records that the new Governor, Virius Lupus , was obliged to buy peace from a fractious northern tribe known as the Maeatae . The succession of militarily distinguished governors who were subsequently appointed suggests that enemies of Rome were posing
9085-613: The largest sector of the county's economy. The county's landmarks span many centuries, ranging from the Six Hills in Stevenage built by local inhabitants during the Roman period, to Leavesden Film Studios . The volume of intact medieval and Tudor buildings surpasses London, in places in well-preserved conservation areas , especially in St Albans , which includes remains of the Roman town of Verulamium . In 913, Hertfordshire
9200-640: The midst of the Norse invasions, Hertfordshire was on the front lines of much of the fighting. King Edward the Elder , in his reconquest of Norse-held lands in what was to become England , established a " burh " or fort in Hertford, which was to curb Norse activities in the area. His father, King Alfred the Great , established the River Lea as a boundary between his kingdom and that of the Norse lord Guthrum , with
9315-407: The names Britannia I , Britannia II , Maxima Caesariensis , and Flavia Caesariensis ; all of these seem to have initially been directed by a governor ( praeses ) of equestrian rank. The 5th-century sources list a fifth province named Valentia and give its governor and Maxima's a consular rank. Ammianus mentions Valentia as well, describing its creation by Count Theodosius in 369 after
9430-644: The north and eastern parts of the county being within the Danelaw . There is little evidence however of Norse placenames within this region, and many of the Anglo-Saxon features remained intact to this day. The county however suffered from renewed Norse raids in the late 10th to early 11th centuries, as armies led by Danish kings Swein Forkbeard and Cnut the Great harried the country as part of their attempts to undermine and overthrow English king Athelred
9545-490: The north and west of the county, forming the Chiltern Hills and the younger Palaeocene , Reading Beds and Eocene , London Clay which occupy the remaining southern part. The eastern half of the county was covered by glaciers during the Ice Age and has a superficial layer of glacial boulder clays . Much of the west – and much more in the east – have richly diverse countryside. These range from beech woods of
9660-419: The north with its capital at Eboracum (York). Valentia is placed variously in northern Wales around Deva ( Chester ); beside Hadrian's Wall around Luguvalium ( Carlisle ); and between the walls along Dere Street . Emperor Constantius returned to Britain in 306, despite his poor health, with an army aiming to invade northern Britain, the provincial defences having been rebuilt in the preceding years. Little
9775-408: The province to press their claim to the throne. As one of his last acts, Severus tried to solve the problem of powerful and rebellious governors in Britain by dividing the province into Britannia Superior and Britannia Inferior . This kept the potential for rebellion in check for almost a century. Historical sources provide little information on the following decades, a period known as
9890-466: The provinces of Roman Britain were organized as a diocese governed by a vicarius under a praetorian prefect who, from 318 to 331, was Junius Bassus who was based at Augusta Treverorum ( Trier ). The vicarius was based at Londinium as the principal city of the diocese. Londinium and Eboracum continued as provincial capitals and the territory was divided up into smaller provinces for administrative efficiency. Civilian and military authority of
10005-651: The purple star-shaped flower with yellow stamens, the Pasqueflower is among endemic county flowers . The rocks of Hertfordshire belong to the great shallow syncline known as the London Basin . The beds dip in a south-easterly direction towards the syncline's lowest point roughly under the River Thames . The most important formations are the Cretaceous Chalk , exposed as the high ground in
10120-537: The quelling of the Great Conspiracy . Ammianus considered it a re-creation of a formerly lost province, leading some to think there had been an earlier fifth province under another name (may be the enigmatic "Vespasiana"? ), and leading others to place Valentia beyond Hadrian's Wall , in the territory abandoned south of the Antonine Wall . Reconstructions of the provinces and provincial capitals during this period partially rely on ecclesiastical records. On
10235-400: The rebels' next target, but concluded it could not be defended. Abandoned, it was destroyed, as was Verulamium (St. Albans). 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
10350-582: 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 refers to two British kings he received as refugees. When some of Tiberius 's ships were carried to Britain in
10465-528: The same town, Airbus (Defence & Space Division) produces satellites. Hatfield was where de Havilland developed the first commercial jet liner, the Comet . Now the site is a business park and new campus for the University of Hertfordshire . This major employment site notably hosts EE , Computacenter and Ocado groceries and other goods e-commerce. Welwyn Garden City hosts Tesco 's UK base, hosts
10580-470: The scale of Luton or Milton Keynes , whose populations exceed 200,000, but its overall population (1.2 million in 2021) is greater than those of the two aforementioned counties. The River Lea near Harpenden runs through Wheathampstead , Welwyn Garden City, Hertford, Ware, and Broxbourne before reaching Cheshunt and ultimately the River Thames. The far west of the county is the most hilly, with
10695-490: The seat of the diocesan vicarius ; places Prima in the west according to Gerald's traditional account but moves its capital to Corinium of the Dobunni ( Cirencester ) on the basis of an artifact recovered there referring to Lucius Septimius, a provincial rector ; places Flavia north of Maxima, with its capital placed at Lindum Colonia ( Lincoln ) to match one emendation of the bishops list from Arles; and places Secunda in
10810-595: The shortcomings of Railtrack , and resulted in speed restrictions and major track replacement. On 10 May 2002, seven people died in the fourth of the Potters Bar rail accidents ; the train was travelling at high speed when it derailed and flipped into the air when one of the carriages slid along the platform where it came to rest. In early December 2005, there were explosions at the Hertfordshire Oil Storage Terminal at Buncefield on
10925-441: The sole civilian official with superior authority, he had general oversight of the administration, as well as direct control, while not absolute, over governors who were part of the prefecture; the other two fiscal departments were not. The early-4th-century Verona List , the late-4th-century work of Sextus Rufus , and the early-5th-century List of Offices and work of Polemius Silvius all list four provinces by some variation of
11040-484: The starting point of his march to the imperial throne, unlike the earlier usurper, Albinus. In the middle of the century, the province was loyal for a few years to the usurper Magnentius , who succeeded Constans following the latter's death. After the defeat and death of Magnentius in the Battle of Mons Seleucus in 353, Constantius II dispatched his chief imperial notary Paulus Catena to Britain to hunt down Magnentius's supporters. The investigation deteriorated into
11155-525: The tribes of the Picts : several Roman forts were destroyed by fire, with human remains and damaged armour at Trimontium (at modern Newstead , in SE Scotland) indicating hostilities at least at that site. There is also circumstantial evidence that auxiliary reinforcements were sent from Germany, and an unnamed British war of the period is mentioned on the gravestone of a tribune of Cyrene . Trajan's Dacian Wars may have led to troop reductions in
11270-519: The village. It is a primary school for children aged between three and eleven. Colney Heath has a football club that currently competes in the Spartan South Midlands League Premier Division and plays the home matches at The Recreation Ground. The village has a rugby league club that also plays at The Recreation Ground. Colney Heath also has a Taekwondo Club which trains at the village hall. The club
11385-528: The western empire, and fought a successful campaign against the Picts and Scots around 384. His continental exploits required troops from Britain, and it appears that forts at Chester and elsewhere were abandoned in this period, triggering raids and settlement in north Wales by the Irish. His rule was ended in 388, but not all the British troops may have returned: the Empire's military resources were stretched to
11500-467: The writing tablets from the fort at Vindolanda in Northumberland , mostly dating to 90–110. These tablets provide evidence for the operation of a Roman fort at the edge of the Roman Empire, where officers' wives maintained polite society while merchants, hauliers and military personnel kept the fort operational and supplied. Around 105 there appears to have been a serious setback at the hands of
11615-555: Was watercress , based in Hemel Hempstead and Berkhamsted supported by reliable, clean chalk rivers. This is a table of trends of regional gross value added of Hertfordshire at current basic prices with figures in millions of British Pounds Sterling. Hertfordshire has the main operational and/or headquarters UK site of some very large employers. Clockwise from north: In Stevenage (a subsidiary of: BAE Systems , Airbus and Finmeccanica ) MBDA , develops missiles . In
11730-407: Was a drawn-out process rather than an inevitable or swift victory. 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
11845-485: Was breached by the Picts and the commanding officer or governor was killed there in what Cassius Dio described as the most serious war of the reign of Commodus . Ulpius Marcellus was sent as replacement governor and by 184 he had won a new peace, only to be faced with a mutiny from his own troops. Unhappy with Marcellus's strictness, they tried to elect a legate named Priscus as usurper governor; he refused, but Marcellus
11960-532: Was crushed by Marcus Aurelius Probus . Soon afterwards, an unnamed governor of one of the British provinces also attempted an uprising. Probus put it down by sending irregular troops of Vandals and Burgundians across the Channel. The Carausian Revolt led to a short-lived Britannic Empire from 286 to 296. Carausius was a Menapian naval commander of the Britannic fleet ; he revolted upon learning of
12075-437: 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
12190-656: Was invaded and colonised by the Anglo-Saxons . By the 6th century, the majority of the modern county was part of the East Saxon kingdom. This relatively short-lived kingdom collapsed in the 9th century, ceding the territory of Hertfordshire to the control of the West Anglians of Mercia . The region finally became an English shire in the 10th century, on the merger of the West Saxon and Mercian kingdoms. In
12305-482: Was lucky to leave the province alive. The Roman army in Britannia continued its insubordination: they sent a delegation of 1,500 to Rome to demand the execution of Tigidius Perennis , a Praetorian prefect who they felt had earlier wronged them by posting lowly equites to legate ranks in Britannia. Commodus met the party outside Rome and agreed to have Perennis killed, but this only made them feel more secure in their mutiny. The future emperor Pertinax (lived 126–193)
12420-490: 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
12535-461: 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,
12650-415: Was sent to Britannia to quell the mutiny and was initially successful in regaining control, but a riot broke out among the troops. Pertinax was attacked and left for dead, and asked to be recalled to Rome, where he briefly succeeded Commodus as emperor in 192. The death of Commodus put into motion a series of events which eventually led to civil war. Following the short reign of Pertinax, several rivals for
12765-417: Was settled by Count Theodosius from 368 with a string of military and civil reforms. Theodosius crossed from Bononia ( Boulogne-sur-Mer ) and marched on Londinium where he began to deal with the invaders and made his base. An amnesty was promised to deserters which enabled Theodosius to regarrison abandoned forts. By the end of the year Hadrian's Wall was retaken and order returned. Considerable reorganization
12880-595: Was the area assigned to a fortress constructed at Hertford under the rule of Edward the Elder . Hertford is derived from the Anglo-Saxon heort ford, meaning deer crossing (of a watercourse). The name Hertfordshire is first recorded in the Anglo-Saxon Chronicle in 1011. Deer feature in many county emblems. Many of the names of the current settlements date back to the Anglo-Saxon period, with many featuring standard placename suffixes attributed to
12995-703: Was the only one directly attested to have taken part. The Legio IX Hispana , the XIV Gemina (later styled Martia Victrix ) and the XX (later styled 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 ( York ) in 71 and on
13110-490: Was undertaken in Britain, including the creation of a new province named Valentia, probably to better address the state of the far north. A new Dux Britanniarum was appointed, Dulcitius, with Civilis to head a new civilian administration. Another imperial usurper, Magnus Maximus , raised the standard of revolt at Segontium ( Caernarfon ) in north Wales in 383, and crossed the English Channel . Maximus held much of
13225-491: 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 ( Colchester ) and routed the part of the IXth Legion that was sent to relieve it. Paulinus rode to London (then called Londinium ),
