Essex is a ceremonial county in the East of England. It is bordered by Cambridgeshire and Suffolk to the north, the North Sea to the east, Kent across the Thames Estuary to the south, Greater London to the south-west, and Hertfordshire to the west. The largest settlement is Southend-on-Sea.

The county has an area of 3670 km2 and had an estimated population of in . The south of the county is densely populated, and includes Southend-on-Sea in the south-east and Basildon in the south-centre. The centre and north of the county is more rural, and its principal settlements include Chelmsford in the centre and Colchester in the north-east. The districts of Chelmsford, Colchester and Southend hold city status. For local government purposes Essex comprises a non-metropolitan county, with twelve districts, and two unitary authority areas: Thurrock and Southend-on-Sea. The county historically included north-east Greater London, the River Lea forming its western border.

Essex is a low-lying county with a flat coastline. It contains pockets of ancient woodland, including Epping Forest in the south-west, and in the north-east shares Dedham Vale national landscape with Suffolk. The coast is one of the longest of any English county, at 562 miles (905 km). It is deeply indented by estuaries, the largest being those of the Stour, which forms the Suffolk border, the Colne, Blackwater, Crouch, and the Thames in the south. Parts of the coast are wetland and salt marsh, including a large expanse at Hamford Water, and it contains several large beaches.

What is now Essex was occupied by the Trinovantes tribe during the Iron Age. They established a settlement at Colchester, which is the oldest recorded town in Britain. The town was conquered by the Romans but subsequently sacked by the Trinovantes during the Boudican revolt. In the Early Middle Ages the region was invaded by the Saxons, who formed the Kingdom of Essex; they were followed by the Vikings, who after winning the Battle of Maldon were able to extract the first Danegeld from King Æthelred. After the Norman Conquest much of the county became a royal forest, and in 1381 the populace of the county were heavily involved in the Peasants' Revolt. The subsequent centuries were more settled, and the county's economy became increasingly tied to that of London; in the nineteenth century the railways allowed coastal resorts such as Clacton-on-Sea to develop and the Port of London to shift downriver to Tilbury. Subsequent development has included the new towns of Basildon and Harlow, the development of the Harwich International Port, and petroleum industry.

History

Essex evolved from the Kingdom of the East Saxons, a polity which is likely to have its roots in the territory of the Iron Age Trinovantes tribe.

Iron Age

In the Iron Age, Essex and parts of southern Suffolk were controlled by the local Trinovantes tribe.

Their production of their own coinage marks them out as one of the more advanced tribes on the island, this advantage (in common with other tribes in the south-east) is probably due to the Belgic element within their elite. Their capital was the oppidum (a type of town) of Colchester, Britain's oldest recorded town, which had its own mint.

The tribe were in extended conflict with their western neighbours, the Catuvellauni, and steadily lost ground. By AD 10 they had come under the complete control of the Catuvellauni, who took Colchester as their own capital.

Roman

The Roman invasion in Essex of AD 43 began with a landing on the south coast, probably in the Richborough area of Kent. After some initial successes against the Britons, they paused to await reinforcements, and the arrival of the Emperor Claudius. The combined army then proceeded to the capital of the Catevellauni-Trinovantes at Colchester, and took it.

Claudius held a review of his invasion force on Lexden Heath where the army formally proclaimed him Imperator. The invasion force that assembled before him included four legions, mounted auxiliaries and an elephant corps – a force of around 30,000 men. At Colchester, the kings of 11 British tribes surrendered to Claudius.

Colchester became a Roman Colonia, with the official name Colonia Claudia Victricensis ('the City of Claudius' Victory'). It was initially the most important city in Roman Britain and in it they established a temple to the God-Emperor Claudius. This was the largest building of its kind in Roman Britain.

The establishment of the Colonia is thought to have involved extensive appropriation of land from local people, this and other grievances led to the Trinovantes joining their northern neighbours, the Iceni, in the Boudiccan revolt. The rebels entered the city, and after a Roman last stand at the temple of Claudius, methodically destroyed it, massacring many thousands. A significant Roman force attempting to relieve Colchester was destroyed in pitched battle, known as the Massacre of the Ninth Legion.

The rebels then proceeded to sack London and St Albans, with Tacitus estimating that 70–80,000 people were killed in the destruction of the three cities. Boudicca was defeated in battle, somewhere in the west midlands, and the Romans are likely to have ravaged the lands of the rebel tribes, so Essex will have suffered greatly.

Despite this, the Trinovantes' identity persisted. Roman provinces were divided into civitas for local government purposes – with a civitas for the Trinovantes strongly implied by Ptolemy. Christianity is thought to have been flourishing among the Trinovantes in the fourth century; indications include the remains of a probable church at Colchester. The church dates from sometime after 320, shortly after Constantine the Great granted freedom of worship to Christians in 313. Other archaeological evidence include a chi-rho symbol etched on a tile at a site in Wickford, and a gold ring inscribed with a chi-rho monogram found at Brentwood.

The late Roman period, and the period shortly after, was the setting for the King Cole legends based around Colchester. One version of the legend concerns St Helena, the mother of Constantine the Great. The legend makes her the daughter of Coel, Duke of the Britons (King Cole) and in it she gives birth to Constantine in Colchester. This, and related legends, are at variance with biographical details as they are now known, but it is likely that Constantine, and his father, Constantius spent time in Colchester during their years in Britain. The presence of St Helena in the country is less certain.

Anglo-Saxon period

The name Essex originates in the Anglo-Saxon period of the Early Middle Ages and has its root in the Anglo-Saxon (Old English) name Ēastseaxe ('East Saxons'), the eastern kingdom of the Saxons who had come from the continent and settled in Britain. Excavations at Mucking have demonstrated the presence of Anglo-Saxon settlers in the early fifth century, however the way in which these settlers became ascendent in the territory of the Trinovantes is not known. Studies suggest a pattern of typically peaceful co-existence, with the structure of the Romano-British landscape being maintained, and with the Saxon settlers believed to have been in the minority.

The first known king of the East Saxons was Sledd in 587, though there are less reliable sources giving an account of Aescwine (other versions call him Erkenwine) founding the kingdom in 527. The early kings of the East Saxons were pagan and uniquely amongst the Anglo-Saxon kingdoms traced their lineage back to Seaxnēat, god of the Saxons, rather than Woden. The kings of Essex are notable for their S-nomenclature, nearly all of them begin with the letter S.

The Kingdom of the East Saxons included not just the subsequent county of Essex, but also Middlesex (including the City of London), much of Hertfordshire and at times also the sub-Kingdom of Surrey. The Middlesex and Hertfordshire parts were known as the Province of the Middle Saxons since at least the early eighth century but it is not known if the province was previously an independent unit that came under East Saxon control. Charter evidence shows that the Kings of Essex appear to have had a greater control in the core area, east of the Lea and Stort, that would subsequently become the county of Essex. In the core area they granted charters freely, but further west they did so while also making reference to their Mercian overlords.

The early kings were pagan, together with much and perhaps by this time all of the population. Sledd's son Sebert converted to Christianity around 604 and St Paul's Cathedral in London was established. On Sebert's death in 616 his sons renounced Christianity and drove out Mellitus, the Bishop of London. The kingdom re-converted after St Cedd, a monk from Lindisfarne and now the patron saint of Essex, converted Sigeberht II the Good around 653.

In 824, Ecgberht, the King of the Wessex and grandfather of Alfred the Great, defeated the Mercians at the Battle of Ellandun in Wiltshire, fundamentally changing the balance of power in southern England. The small kingdoms of Essex, Sussex and of Kent, previously independent albeit under Mercian overlordship, were subsequently fully absorbed into Wessex.

The later Anglo-Saxon period shows three major battles fought with the Norse recorded in Essex; the Battle of Benfleet in 894, the Battle of Maldon in 991 and the Battle of Assandun (probably at either Ashingdon or Ashdon) in 1016. The county of Essex was formed from the core area, east of the River Lea, of the former Kingdom of the East Saxons in the 9th or 10th centuries and divided into groupings called hundreds.

Before the Norman Conquest the East Saxons were subsumed into the Kingdom of England.

After the Norman Conquest

Having conquered England, William the Conqueror initially based himself at Barking Abbey, an already ancient nunnery, for several months while a secure base, which eventually became the Tower of London, could be established in the city. While at Barking William received the submission of some of England's leading nobles. The invaders established a number of castles in the county, to help protect the new elites in a hostile country. There were castles at Colchester, Castle Hedingham, Rayleigh, Pleshey and elsewhere. Hadleigh Castle was developed much later, in the thirteenth century.

After the arrival of the Normans, the Forest of Essex was established as a royal forest, however, at that time, the term was a legal term. There was a weak correlation between the area covered by the Forest of Essex (the large majority of the county) and the much smaller area covered by woodland. An analysis of Domesday returns for Essex has shown that the Forest of Essex was mostly farmland, and that the county as a whole was 20% wooded in 1086. In 1218, Chelmsford became the county town.

After that point population growth caused the proportion of woodland to fall steadily until the arrival of the Black Death, in 1348, killed between a third and a half of England's population, leading to a long term stabilisation of the extent of woodland. Similarly, various pressures led to areas being removed from the legal Forest of Essex and it ceased to exist as a legal entity after 1327, and after that time Forest Law applied to smaller areas: the forests of Writtle (near Chelmsford), long lost Kingswood (near Colchester), Hatfield, and Waltham Forest.

Waltham Forest had covered parts of the Hundreds of Waltham, Becontree and Ongar. It also included the physical woodland areas subsequently legally afforested (designated as a legal forest) and known as Epping Forest and Hainault Forest).

Peasants' Revolt, 1381

The Black Death significantly reduced England's population, leading to a change in the balance of power between the working population on one hand, and their masters and employers on the other. Over a period of several decades, national government brought in legislation to reverse the situation, but it was only partially successful and led to simmering resentment.

By 1381, England's economic situation was very poor due to the war with France, so a new Poll Tax was levied with commissioners being sent round the country to interrogate local officials in an attempt to ensure tax evasion was reduced and more money extracted. This was hugely unpopular and the Peasants' Revolt broke out in Brentwood on 1 June 1381. The revolt was partly inspired by the egalitarian preaching of the radical Essex priest John Ball.

Several thousand Essex rebels gathered at Bocking on 4 June, and then divided. Some heading to Suffolk to raise rebellion there, with the rest heading to London, some directly – via Bow Bridge and others may have gone via Kent. A large force of Kentish rebels under Wat Tyler, who may himself have been from Essex, also advanced on London while revolt also spread to a number of other parts of the country.

The rebels gained access to the walled City of London and gained control of the Tower of London. They carried out extensive looting in the capital and executed a number of their enemies, but the revolt began to dissipate after the events at West Smithfield on 15 June, when the Mayor of London, William Walworth, killed the rebel leader Wat Tyler. The rebels prepared to fire arrows at the royal party but the 15 year old King Richard II rode toward the crowd and spoke to them, defusing the situation, in part by making a series of promises he did not subsequently keep.

Having bought himself time, Richard was able to receive reinforcements and then crush the rebellion in Essex and elsewhere. His forces defeated rebels in battle at Billericay on 28 June, and there were mass executions including hangings and disembowellings at Chelmsford and Colchester.
