Title: Kingdom of Sussex
Content:  At the time of the South Saxons it is unlikely that they would have had a capital in Sussex. The archaeologist Martin Biddle said that "the evidence we have for the residences and itineraries of English kings before the Norman conquest is all too thin" and according to Frank Stenton  "In the eleventh century the conception of a capital city had not yet taken a deﬁnite shape anywhere in the west. The centre of government in England was the kings’ mobile court. The king was free to hold a council at any point in his realm.." In Roman times Chichester was known as Noviomagus Reginorum and served as the capital of the Civitas Reginorum, a client kingdom ruled by Tiberius Claudius Cogidubnus. After the departure of the Romans, Noviomagus appears to have been largely abandoned. The Anglo Saxon Chronicle suggests that 
Title: Geography of Sussex
Content:  Sussex is a historic county and cultural region in the south of England corresponding roughly in area to the ancient Kingdom of Sussex. It is bounded on the north by Surrey, north-east by Kent, south by the English Channel, and west by Hampshire, and is divided for local government into West Sussex and East Sussex and the city of Brighton and Hove. The city of Brighton & Hove was created a unitary authority in 1997, and was granted City status in 2000. Until then Chichester had been Sussex's only city. By convention, Chichester is Sussex's capital city and Lewes is Sussex's county town. Sussex encompasses approximately 3783 km2. It is

In 1997, Brighton and Hove became a self-administered unitary authority; it was granted city status in 2000, whilst remaining part of the ceremonial county of East Sussex. By convention Chichester is Sussex's capital city and Lewes is Sussex's county town. Chichester has been seen as the capital of Sussex since it became the political centre of the kingdom of Sussex by the 8th century. Due in part to its more central location within the county, Lewes has been the county town of Sussex since the 15th century. Both titles are honorary and there currently little administration organised on a Sussex-wide basis, since the creation of county councils for East and West Sussex in 1889. One exception is Sussex Police, and the elected position of

For the modern county see Sussex or the current administrative divisions of East Sussex and West Sussex. The Kingdom of the South Saxons, today referred to as the Kingdom of Sussex (Sūþseaxna rīce), was one of the seven traditional kingdoms of the Heptarchy of Anglo-Saxon England. On the south coast of the island of Great Britain, it was originally a sixth-century Saxon colony and later an independent kingdom. The kingdom remains one of the least known of the Anglo-Saxon polities, with no surviving king-list, several local rulers 
Title: History of local government in Sussex
Content:   Sussex originated in the 5th century as the Kingdom of Sussex, which in the 9th century was annexed by the Kingdom of Wessex, which with further expansions became the Kingdom of England. While Sussex retained its independence it is likely that it would have had a regular assembly or folkmoot. Sussex seems to have had a greater degree of decentralisation than other kingdoms. For a period during the 760s there may have been as many as four of five kings based within the territory, perhaps with each ruling over a distinct tribal territory, perhaps on a temporary basis. It seems possible that the people of the Haestingas may have had their own ruler for a while, and another sub-division may have been along the River Adur. At some stage in 
Title: Sussex
Content:  Sussex, from the Old English Sūþsēaxe (South Saxons), is a historic county in South East England that was formerly an independent medieval Anglo-Saxon kingdom. It is bounded to the west by Hampshire, north by Surrey, northeast by Kent, south by the English Channel, and divided for many purposes into the ceremonial counties of West Sussex and East Sussex. Brighton and Hove, though part of East Sussex, was made a unitary authority in 1997, and as such, is administered independently of the rest of East Sussex. Brighton and Hove was granted City status in 2000. Until then, Chichester was Sussex's only city. The Brighton and Hove built-up

Content:   The shield or emblem of Sussex, sometimes referred to as a coat of arms, consists of six gold martlets on a blue field. It was attributed to the Kingdom of Sussex later in a work called "Saxon Heptarchy" by John Speed that dates from 1611. The depiction shows Ælle of Sussex, the founder and first king of Sussex, holding the shield over his shoulder.

The South Saxons were ruled by the kings of Sussex until the country was annexed by Wessex, probably in 827, in the aftermath of the Battle of Ellendun. The foundation legend of the kingdom of Sussex is that in 477 Ælle and his three sons arrived in three ships, conquering what is now Sussex. Ælle became overlord, or Bretwalda, over the other Anglo-Saxon kingdoms south of the Humber. Historians are divided over whether or not Ælle really existed, however archaeological evidence supports the view that a short-lived expansion of South Saxon authority as far as the Midlands may

What the archaeology does show is that the initial settlement, of the South Saxons, was in the downland areas, between the River Ouse and River Cuckmere to the east of Sussex. From there the South Saxons migrated to the west of Sussex and by the 680s the area between Chichester and Selsey had become the political and ecclesiastical centre of the kingdom with the kings residence in Orreo Regis (Kingsham), south west of Chichester, and Wilfrid's religious centre in Selsey. According to Martin Welch "After the Romans left there is no evidence for the reoccupation of Chichester till the 9th century", when it was rebuilt and fortified as part of a programme of defence, instigated by Alfred the Great, of Wessex, to protect against Danish raids.
Title: West Sussex
Content:  Sussex and parts of Crawley being transferred to West Sussex administration from East Sussex. In the 2011 census, West Sussex recorded a population of 806,900. The county has a long history of human settlement dating back to the Lower Paleolithic era. The Romans conquered West Sussex's indigenous Britons, and incorporated the area as a Roman province. During the Early Middle Ages, the Saxons settled the area, establishing the Kingdom of Sussex in 477, which lasted until c. 827 when the kingdom was annexed by Wessex. West Sussex has a range of scenery, including wealden, downland and coastal. The highest point of the county is Blackdown, at 280 metres (919 ft). It has a number of stately homes including Goodwood, Petworth House and Uppark, and castles such as Arundel Castle and Bramber Castle. Over half the county is protected countryside, offering walking, cycling and other recreational opportunities.
