Sussex (/ˈsʌsɪks/; from the ) is an area of South East England that was historically a kingdom and, later, a county. The current ceremonial counties of East Sussex and West Sussex cover approximately the same area. The two ceremonial counties border Surrey to the north, Kent to the north-east, the English Channel to the south, and Hampshire to the west. Sussex contains the city of Brighton and Hove and its wider city region, part of the South Downs National Park and the national landscape of the High Weald, and Chichester Harbour. Its coastline is long.
The Kingdom of Sussex emerged in the fifth century in the area that had previously been inhabited by the Regni tribe in the Romano-British period. In about 827, shortly after the Battle of Ellendun, Sussex was conquered by Wessex. From 860 it was ruled by the kings of Wessex, and in 927 it became part of the Kingdom of England. By the Norman period, Sussex was subdivided into six administrative districts known as rapes, which were themselves divided into hundreds. By the sixteenth century, the eastern three rapes and the western three rapes had been combined for most meetings of the court of quarter sessions, a division which was reinforced when the administrative counties of East Sussex and West Sussex were established in 1889. Subsequent local government reforms maintained the division into east and west. The county retained a single lord lieutenant and sheriff until 1974, when they were replaced with separate posts for East and West Sussex and Sussex lost its status as a ceremonial county.
Sussex is widely regarded as a single unified entity for some purposes, including provision of some public services,e.g. for Sussex Police, NHS Sussex, the Sussex Wildlife Trust, the Sussex Inshore Fisheries and Conservation Authority food and drinke.g. wine, beer, cheese and sport.e.g. Sussex County Cricket Club, Sussex County Football Association, Sussex Rugby Football Union In 2007, Sussex Day was created to celebrate the county's culture and history. In February 2025, the UK Government approved plans to devolve powers to a new combined county authority for East Sussex, West Sussex, and Brighton and Hove, to be headed by a directly elected mayor.
Toponymy The name "Sussex" is derived from the Middle English , which is in turn derived from the Old English , meaning "(land or people) of the South Saxons" (cf. Essex, Middlesex and Wessex). The South Saxons were a Germanic tribe that settled in the region from the North German Plain during the fifth and sixth centuries.
The earliest-known usage of the term South Saxons (Latin: ) is in a royal charter of 689 which names them and their king, Noðhelm, although the term may well have been in use for some time before that. The monastic chronicler who wrote up the entry classifying the invasion seems to have got his dates wrong; recent scholars have suggested he might have been a quarter of a century too late.
In the Domesday Book of 1086, Sussex is recorded as Sudsexe.
Three United States counties (in Delaware, New Jersey and Virginia), and a former county/land division of Western Australia, are named after Sussex.
Symbols
The flag of Sussex consists of six gold martlets, or heraldic swallows, on a blue background, blazoned as Azure, six martlets or. Recognised by the Flag Institute on 20 May 2011, its design is based on the heraldic shield of Sussex. The first-known recording of this emblem being used to represent the county was in 1611 when cartographer John Speed deployed it to represent the Kingdom of the South Saxons. However, it seems that Speed was repeating an earlier association between the emblem and the county, rather than being the inventor of the association. It is now firmly regarded that the county emblem originated and derived from the coat of arms of the 14th-century Knight of the Shire, Sir John de Radynden. Sussex's six martlets are today held to symbolise the traditional six sub-divisions of the county known as rapes.
Sussex by the Sea is regarded as the unofficial anthem of Sussex; it was composed by William Ward-Higgs in 1907, perhaps originally from the lyrics of Rudyard Kipling's poem entitled Sussex. Adopted by the Royal Sussex Regiment and popularised in World War I, it is sung at celebrations across the county, including those at Lewes Bonfire, and at sports matches, including those of Brighton and Hove Albion Football Club and Sussex County Cricket Club.
The county day, called Sussex Day, is celebrated annually on 16 June, the feast day of St Richard of Chichester, Sussex's patron saint, whose shrine at Chichester Cathedral was an important place of pilgrimage in the Middle Ages.
Sussex's motto, We wunt be druv, is a Sussex dialect expression meaning "we will not be pushed around" and reflects the traditionally independent nature of Sussex men and women. The round-headed rampion, also known as the "Pride of Sussex", was adopted as Sussex's county flower in 2002.
Geography
Landscape The physical geography of Sussex relies heavily on its lying on the southern part of the Wealden anticline, the major features of which are the high lands that cross the county in a west to east direction: the Weald itself and the South Downs. Natural England has identified the following seven national character areas in Sussex:
South Coast Plain South Downs Wealden Greensand Low Weald High Weald Pevensey Levels Romney Marshes
At , Blackdown is the highest point in Sussex, or county top. With a height of Ditchling Beacon is the highest point in East Sussex. At long, the River Medway is the longest river flowing through Sussex. The longest river entirely in Sussex is the River Arun, which is long. Sussex's largest lakes are man-made reservoirs. The largest is Bewl Water on the Kent border, while the largest wholly within Sussex is Ardingly Reservoir.
Climate The coastal resorts of Sussex and neighbouring Hampshire are the sunniest places in the United Kingdom. The coast has consistently more sunshine than the inland areas: sea breezes, blowing off the sea, tend to clear any cloud from the coast. The sunshine average is approximately 1,900 hours a year; this is much higher than the UK average of 1,340 hours a year. Most of Sussex lies in hardiness zone 8; the exception is the coastal plain west of Brighton, which lies in the milder zone 9.
Rainfall is below average with the heaviest precipitation on the South Downs with of rainfall per year. The close proximity of Sussex to the Continent of Europe, results in cold spells in winter and hot, humid weather in summer.
The climate of the coastal districts is strongly influenced by the sea, which, because of its tendency to warm up slower than land, can result in cooler temperatures than inland in the summer. In the autumn months, the coast sometimes has higher temperatures. Rainfall during the summer months is mainly from thunderstorms and thundery showers; from January to March the heavier rainfall is due to prevailing south-westerly frontal systems.
In winter, the east winds can be as cold as further inland. Selsey is known as a tornado hotspot, with small tornadoes hitting the town in 1986, 1998 and 2000, with the 1998 tornado causing an estimated £10 million of damage to 1,000 buildings.
Conurbations Most of Sussex's population is distributed in an east–west line along the English Channel coast or on the east–west line of the A272. The exception to this pattern is the 20th-century north–south development on the A23-Brighton line corridor, Sussex's main link to London. Sussex's population is dominated by the Brighton/Worthing/Littlehampton conurbation that, with a population of more than 470,000, is home to almost 1 in 3 of Sussex's population. According to the ONS urban area populations for continuous built-up areas, these are the five largest conurbations: RankUrban areaPopulationStatisticallocalitiesKS01 Usual resident population Census 2001, Key Statistics for urban areas Office for National Statistics.

Population The combined population of Sussex as of 2021 was about 1.7 million.Combined population of local authority areas of Brighton and Hove (277,103), East Sussex, (557,229) and West Sussex (858,852) In 2021, Sussex had a population density of 451 per km2, higher than the average for England of 434 per km2.
The earliest statement as to the population of Sussex is made by Bede, who describes the county in the year 681 as containing land for 7,000 families; allowing ten to a family (a reasonable estimate at that date), the total population would be 70,000. In 1693 the county is said to have contained 21,537 houses. The 1801 census found that the population was 159,311. The decline of the Sussex ironworks probably accounts for the small increase in population during several centuries, although after the Massacre of St Bartholomew upwards of 1,500 Huguenots landed at Rye, and in 1685, after the revocation of the Edict of Nantes, many more refugees were added to the county. The population of Sussex was 550,446 in 1891 and 605,202 in 1901.
History
Beginnings
Finds at Eartham Pit in Boxgrove show that the area has some of the earliest hominid remains in Europe, dating back some 500,000 years and known as Boxgrove Man or Homo heidelbergensis. At a site near Pulborough called The Beedings, tools have been found that date from around 35,000 years ago and that are thought to be from either the last Neanderthals in northern Europe or pioneer populations of modern humans. The thriving population lived by hunting game such as horses, bison, mammoths and woolly rhinoceros. Around 6000 BC, the ice sheet over the North Sea melted, sea levels rose and the meltwaters burst south and westwards, creating the English Channel and cutting the people of Sussex off from their Mesolithic kinsmen to the south. Later in the Neolithic period, the area of the South Downs above Worthing was one of Britain's largest and most important flint-mining centres. The flints were used to help fell trees for agriculture. The oldest of these mines, at Church Hill in Findon, has been carbon-dated to 4500 BC to 3750 BC, making it one of the earliest known mines in Britain. Flint tools from Cissbury have been found as far away as the eastern Mediterranean.
Sussex is rich in remains from the Bronze and Iron Ages, in particular the Bronze Age barrows known as the Devil's Jumps and Cissbury Ring, one of Britain's largest hillforts. Towards the end of the Iron Age in 75 BC people from the Atrebates, one of the tribes of the Belgae, a mix of Celtic and German stock, invaded and occupied southern Britain.Armstrong. A History of Sussex. Ch. 3. This was followed by an invasion by the Roman army under Julius Caesar that temporarily occupied south-eastern Britain in 55 BC. Soon after the first Roman invasion had ended, the Celtic Regni tribe under their leader Commius initially occupied the Manhood Peninsula. Eppillus, Verica and Cogidubnus followed Commius as rulers of the Regni or southern Atrebates, a region which included most of Sussex, with their capital in the Selsey area.Cunliffe.
