Kingdom of Essex
The Kingdom of the East Saxons (; ), referred to as the Kingdom of Essex , was one of the seven traditional kingdoms of the Anglo-Saxon Heptarchy. It was founded in the 6th century and covered the territory later occupied by the counties of Essex, Middlesex, much of Hertfordshire and (for a short while) west Kent. The last king of Essex was Sigered of Essex and in 825, he ceded the kingdom to Ecgberht, King of Wessex. Extent. The kingdom was bounded to the north by the River Stour and the Kingdom of East Anglia, to the south by  the River Thames and Kent, to the east lay the North Sea and to the west Mercia. The territory included the remains of two provincial Roman capitals, Colchester and London. The kingdom included the Middle Saxon Province, which included the area of the later county of Middlesex, and most if not all of Hertfordshire Although the province is only ever recorded as a part of the East Saxon kingdom, charter evidence shows that it was not part of their core territory. In the core area they granted charters freely, but further west they did so while also making reference to  their Mercian overlords.At times, Essex was ruled jointly by co-Kings, and it thought that the Middle Saxon Province is likely to have been the domain of one of these co-kings. The links to Essex between Middlesex and parts of Hertfordshire were long reflected in the Diocese of London, re-established in 604 as the East Saxon see, and its boundaries continued to be based on the Kingdom of Essex until the nineteenth century. The East Saxons also had intermittent control of Surrey. For a brief period in the 8th century, the Kingdom of Essex controlled west Kent . The modern English county of Essex maintains the historic northern and the southern borders, but only covers the territory east of the River Lea, the other parts being lost to neighbouring Mercia during the 8th century. In the Tribal Hidage it is listed as containing 7,000 hides. History. Although the kingdom of Essex was one of the kingdoms of the Heptarchy, its history is not well documented. It produced relatively few Anglo-Saxon charters and no version of the "Anglo-Saxon Chronicle"; in fact the only mention in the chronicle concerns Bishop Mellitus. As a result, the kingdom is regarded  as comparatively obscure. For most of the kingdom's existence, the Essex king was subservient to an overlord – variously the kings of Kent, East Anglia or Mercia. Origin. Saxon occupation of land that was to form the kingdom had begun by the early 5th century at Mucking and other locations. A large proportion of these original settlers came from Old Saxony. According to British legend (see: Historia Brittonum) the territory known later as Essex was ceded by the Celtic Britons to the Saxons following the infamous Treason of the Long Knives, which occurred ca. 460 during the reign of High  King Vortigern. Della Hooke relates the territory ruled by the kings of Essex to the pre-Roman territory of the Trinovantes. 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 kingdom of Essex grew by the absorption of smaller subkingdoms or Saxon tribal groups. There are a number of suggestions for the location of these subkingdoms including: Essex monarchy. Essex emerged as a single kingdom during the 6th century. The dates, names and achievements of the Essex  kings, like those of most early rulers in the Heptarchy, remain conjectural. The historical identification of the kings of Essex, including the evidence and a reconstructed genealogy are discussed extensively by Yorke. The dynasty claimed descent from Woden via Seaxnēat. A genealogy of the Essex royal house was prepared in Wessex in the 9th century. Unfortunately the surviving copy is somewhat mutilated. At times during the history of the kingdom several sub-kings within Essex appear to have been able to rule simultaneously. They may have exercised authority over different parts of the kingdom. The first recorded king, according to  the East Saxon King List, was Æscwine of Essex, to which a date of 527 is given for the start of his reign, although there are some difficulties with the date of his reign, and Sledd of Essex is listed as the founder of the Essex royal house by other sources. The kings of Essex are notable for their S-nomenclature, nearly all their names begin with the letter S. The Essex kings issued coins that echoed those issued by Cunobeline simultaneously asserting a link to the first century rulers while emphasising independence from Mercia. Christianity. Christianity is thought to  have been flourishing among the Trinovantes in the fourth century (in the late Roman period), indications include the remains of a probable church at Colchester, the church dates from sometime after 320, shortly after the 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. It's not clear to what extent, if any, Christianity persisted by the time of the pagan East Saxon kings in the sixth century . The earliest English record of the kingdom dates to Bede's "Historia ecclesiastica gentis Anglorum", which noted the arrival of Bishop (later Saint) Mellitus in London in 604. Æthelberht (King of Kent and overlord of southern England according to Bede) was in a position to exercise some authority in Essex shortly after 604, when his intervention helped in the conversion of King Saebert of Essex (son of Sledd), his nephew, to Christianity. It was Æthelberht, and not Sæberht, who built and endowed St. Pauls in London, where St. Paul’s Cathedral now stands. Bede describes Æthelberht as Sæberht’s overlord . After the death of Saebert in AD 616, Mellitus was driven out and the kingdom reverted to paganism. This may have been the result of opposition to Kentish influence in Essex affairs rather than being specifically anti-Christian. The kingdom reconverted to Christianity under Sigeberht II the Good following a mission by St Cedd who established monasteries at "Tilaburg" (probably East Tilbury, but possibly West Tilbury) and "Ithancester" (almost certainly Bradwell-on-Sea). A royal tomb at Prittlewell was discovered and excavated in 2003. Finds included gold foil crosses, suggesting the occupant was Christian. If the occupant was a king , it was probably either Saebert or Sigeberht (murdered AD 653). It is, however, also possible that the occupant was not royal, but simply a wealthy and powerful individual whose identity has gone unrecorded. Essex reverted to Paganism again in 660 with the ascension of the Pagan King Swithelm of Essex. He converted in 662, but died in 664. He was succeeded by his two sons, Sigehere and Sæbbi. A plague the same year caused Sigehere and his people to recant their Christianity and Essex reverted to Paganism a third time. This rebellion was suppressed by Wulfhere of Mercia who established  himself as overlord. Bede describes Sigehere and Sæbbi as "rulers … under Wulfhere, king of the Mercians". Wulfhere sent Jaruman, the bishop of Lichfield, to reconvert the East Saxons. Wine (in 666) and Erkenwald (in 675) were appointed bishops of London with spiritual authority over the East Saxon Kingdom. A small stone chest bearing the name of Sæbbi of Essex (r.664–683) was visible in Old St Paul's Cathedral until the Great Fire of London of 1666 when the cathedral and the tombs within it were lost. The inscription on the chest was recorded by Paul Hentzner and translated by Robert  Naunton as reading: "Here lies Seba, King of the East Saxons, who was converted to the faith by St. Erkenwald, Bishop of London, A.D. 677." Although London (and the rest of Middlesex) was lost by the East Saxons in the 8th century, the bishops of London continued to exert spiritual authority over Essex as a kingdom, shire and county until 1845. Later history and end. Despite the comparative obscurity of the kingdom, there were strong connections between Essex and the Kentish kingdom across the river Thames which led to the marriage of King Sledd to Ricula, sister of the king , Aethelbert of Kent. For a brief period in the 8th century the kingdom included west Kent. During this period, Essex kings were issuing their own sceattas (coins), perhaps as an assertion of their own independence. However, by the mid 8th century much of the kingdom, including London, had fallen to Mercia and the rump of Essex, roughly the modern county, was now subordinate to the same. After the defeat of the Mercian king Beornwulf around AD 825, Sigered, the last king of Essex, ceded the kingdom which then became a possession of the Wessex king Egbert. The Mercians continued to  control parts of Essex and may have supported a pretender to the Essex throne since a Sigeric "rex Orientalem Saxonum" witnessed a Mercian charter after AD 825. During the ninth century, Essex was part of a sub-kingdom that included Sussex, Surrey and Kent. Sometime between 878 and 886, the territory was formally ceded by Wessex to the Danelaw kingdom of East Anglia, under the Treaty of Alfred and Guthrum. After the reconquest by Edward the Elder the king's representative in Essex was styled an ealdorman and Essex came to be regarded as a shire. List of kings.
