Jersey (; Jèrri), officially the Bailiwick of Jersey, is an autonomous and self-governing British Crown Dependency in Northwestern Europe 14 mi off the Cotentin Peninsula of north-west France. At 45 sqmi, the main island, Jersey, is the largest of the Channel Islands. Although not a sovereign state, Jersey has its own legal, fiscal and governmental systems; on that basis, it is regarded as a small nation or island country. Jersey's territory also includes some surrounding uninhabited islands and rocks. As of 2021, the island had a population of 103,267.

Historically part of the Duchy of Normandy, Jersey remained loyal to the English Crown when the English kings lost mainland Normandy, but it never became part of the Kingdom of England. From then until the end of the Napoleonic Wars, Jersey was at the frontline of Anglo-French Wars and was invaded a number of times, leading to the construction of fortifications such as Mont Orgueil Castle and to a thriving smuggling industry. The island was invaded and occupied by Nazi German forces during the Second World War until 9 May 1945, now celebrated as the island's national day.

Jersey is a parliamentary democracy under a constitutional monarchy, with its own financial, legal and judicial systems, and the power of self-determination. The Bailiff is the civil head of the island, the Chief Minister leads the island's government, and the Lieutenant Governor represents the British monarch, who is the head of state. The island is not part of the United Kingdom and has a separate international identity, but the UK government manages its defence, international representation and certain policy areas, such as nationality law.

The island has a large financial services industry, as well as agriculture and tourism. Its currency is the Pound sterling with a local issue of banknotes and coins. British cultural influence on the island is evident in its use of English as the main language and its participation in British sporting leagues, but the island also has a strong Norman-French culture, reflected by its historic dialect of the Norman language, Jèrriais.

Name

The Channel Islands are mentioned in the Antonine Itinerary as the following: Sarnia, Caesarea, Barsa, Silia and Andium, but Jersey cannot be identified specifically because none corresponds directly to the present names. The name Caesarea has been used as the Latin name for Jersey (also in its French version Césarée) since William Camden's Britannia, and is used in titles of associations and institutions today. The Latin name Caesarea was also applied to the colony of New Jersey as Nova Caesarea.

Andium, Agna and Augia were used in antiquity.

Scholars variously surmise that Jersey and Jèrri derive from (Old Norse for 'earth') or jarl ('earl'), or perhaps the Norse personal name Geirr (thus Geirrsey, 'Geirr's Island'). The ending denotes an island, as in Guernsey or Surtsey.

History

Prehistoric and ancient Jersey

The La Cotte de St Brelade site on the southwest coast indicates that what is now Jersey was inhabited by Neanderthals as early as 200-250,000 years ago, when the island was connected to the French mainland. The inland Les Varines site indicates that Jersey was occupied by modern humans of the late Upper Palaeolithic Magdalenian culture towards the end of the last ice age. During the early part of the Mesolithic (when Jersey was inhabited by hunter-gatherers, as indicated by microlith finds), Jersey remained part of France, but had become an island by towards the end of period by 5500 BC. The Neolithic occupation of the island shows the construction of dolmens, such as La Hougue Bie. Evidence of Bronze Age and early Iron Age settlements can be found in many locations around the island.

Archaeological evidence of Roman influence has been found, in particular at Les Landes.

Christianity was brought to the island by migrants from Brittany in c. fifth – sixth century CE. In the sixth century, the island's patron saint Helier lived at the Hermitage on L'Islet (now Elizabeth Castle). Legend states that Helier was beheaded by raiders and subsequently lifted his head and walked to shore.

Early Medieval period

In the ninth century the island was raided by Vikings and in 933 it was annexed to Normandy by William Longsword. When Duke William the Conqueror became King of England in 1066, the island remained part of the Norman possessions. However, in 1204, when Normandy was returned to the French king, the island remained a possession of the English crown, though never incorporated into England. Although traditionally attributed to the Constitutions of King John, Jersey's self-governance is more accurately founded on a succession of royal charters and long-standing constitutional conventions, with the precise origins of its autonomy remaining a subject of historical debate. Nevertheless, the island continued to follow Norman customs and laws. The King also appointed a Bailiff and a Warden (now Lieutenant-Governor). The period of English rule was marked by wars between England and France, as such a military fortress was built at Mont Orgueil.

During the Tudor period, the split between the Church of England and the Vatican led to islanders adopting the Protestant religion. During the reign of Elizabeth, French refugees brought strict Calvinism to the island, which remained the common religion until 1617. In the late 16th century, islanders travelled across the North Atlantic to participate in the Newfoundland fisheries.

In recognition for help given to him during his exile in Jersey in the 1640s, King Charles II of England gave Vice Admiral Sir George Carteret, bailiff and governor, a large grant of land in the American colonies in between the Hudson and Delaware rivers, which he promptly named New Jersey. It is now a state in the United States.

Early modern period

In 1769, the island suffered food supply shortages, leading to an insurrection on 28 September known as the Corn Riots. The States met at Elizabeth Castle and decided to request help from the King. However, in 1771 the Crown demanded reforms to the island's governance, leading to the Code of 1771 and removed the powers of the Royal Court to make laws without the States.

In 1781, during the American Revolutionary War, the island was invaded by a French force which captured St Helier, but was defeated by Major Peirson's army at the Battle of Jersey.

The 19th century saw the improvement of the road network under General Don, the construction of two railway lines, the improvement of transport links to England, and the construction of new piers and harbours in St Helier. This grew the tourism industry in the island and led to the immigration of thousands of English residents, leading to a cultural shift towards a more anglicised island culture.

Island politics in this period were split between the conservative Laurel party and the progressive Rose party, as the lie of power shifted increasingly to the States from the Crown. In the 1850s, the French author Victor Hugo lived in Jersey, but was expelled for insulting the Queen, so he moved on to Guernsey.

20th century–present

During the Second World War, 6,500 Jersey residents were evacuated by their own choice to the UK out of a total population of 50,000. Jersey was occupied by Germany from 1 July 1940 until 9 May 1945, when Germany surrendered. During this time the Germans constructed many fortifications using slave labour imported onto the island from many different countries occupied or at war with Germany. After 1944, supplies from France were interrupted by the D-Day landings, and food on the island became scarce. The SS Vega was sent to the island carrying Red Cross supplies and news of the success of the Allied advance in Europe. During the Nazi occupation, a resistance cell was created by communist activist Norman Le Brocq and the Jersey Communist Party, whose communist ideology of forming a 'United Front' led to the creation of the Jersey Democratic Movement.

The Channel Islands had to wait for the German surrender to be liberated. 9 May is celebrated as the island's Liberation Day, where there are celebrations in Liberation Square. After Liberation, the States were reformed, becoming wholly democratically elected, and universal franchise was implemented. Since liberation, the island has grown in population and adopted new industries, especially the finance industry.

Politics

Jersey is a Crown Dependency. It is not part of the United Kingdom, but it is part of the 'British Islands', a legal definition encompassing the UK and the Crown Dependences. As a Crown Dependency, Jersey is autonomous and self-governing, with its own independent legal, administrative and fiscal systems. Jersey's government has described Jersey as a "self-governing, democratic country with the power of self-determination". Jersey and its people have historically been described as a nation.

Because Jersey is a dependency of the British Crown, King Charles III reigns in Jersey. "The Crown" is defined by the Law Officers of the Crown as the "Crown in right of Jersey". The King's representative and adviser in the island is the Lieutenant Governor of Jersey – Vice-Admiral Jerry Kyd since 8 October 2022. He is a formal point of contact between Jersey ministers and the UK Government and carries out some ceremonial functions in relation to immigration control, deportation, naturalisation and the issue of passports.

In 1973, the Royal Commission on the Constitution set out the duties of the Crown to the island as including: ultimate responsibility for the 'good government' of the Crown Dependencies; ratification of island legislation by Order-in-Council (royal assent); international representation, subject to consultation with the island authorities before concluding any agreement which would apply to them; ensuring the islands meet their international obligations; and defence.

Legislature and government

The States Assembly is Jersey's unicameral legislature. It has 54 members in law, of whom 49 are elected and entitled to vote. Following the 2026 general election, the elected members comprise nine senators elected in a single island-wide constituency, the connétables of the twelve civil parishes, who sit by virtue of their parish offices, and 28 deputies elected from nine constituencies. All elected members serve four-year terms.

The preceding 2022–2026 Assembly had instead comprised twelve connétables and 37 deputies, with no senators. Senators had previously been elected island-wide, but the office was removed as part of reforms implemented for the 2022 election. Proposals to remove the connétables from the Assembly were not adopted. The island-wide senatorial mandate was subsequently restored for the election held on 7 June 2026.

The five remaining members of the States are the Bailiff, the Lieutenant-Governor, the Dean of Jersey, the Attorney General and the Solicitor General. They sit by virtue of their respective constitutional or Crown offices and may speak in the Assembly, but may not vote. The Bailiff is President and ordinarily presides over sittings of the Assembly. The Deputy Bailiff may preside when the Bailiff is unavailable, but is not separately constituted as a member of the States. The Bailiff is also head of Jersey's judiciary and, as civic head of the island, performs various ceremonial functions.

Jersey has historically had low voter turnout. Over the 30 years to 2025, turnout at elections averaged 44.1%, which was lower than in any OECD member country and the lowest of the three Crown Dependencies. Surveys conducted following the 2022 election found that the most commonly reported reasons for not voting included apathy, mistrust and disinterest in the political system.

Executive government is led by the Council of Ministers, comprising the Chief Minister and at least seven other ministers. Ministers are elected by the States Assembly following the selection of the Chief Minister. The Council is formed, and the Chief Minister formally takes office, once the final minister required to constitute it has been selected. The Council coordinates government policy and administration and is accountable to the Assembly.

The Chief Minister and other ministers may appoint one or more elected members as assistant ministers, subject to the statutory aggregate limit on the number of ministers and assistant ministers. Assistant ministers are members of the executive but are not themselves members of the Council of Ministers. The Chief Executive Officer heads the public service. Some governmental and administrative functions are carried out through the island's parishes.

Law

Jersey is a distinct jurisdiction for cases in multiple jurisdictions (conflict of laws). It is separate from the other jurisdictions in the British Islands, including the other Channel Islands and England and Wales.

Jersey law has been influenced by several different legal traditions, in particular Norman customary law, English common law and modern French civil law. Jersey's legal system is therefore described as 'mixed' or 'pluralistic'. Sources of law are in both the French and English languages, although since the 1950s the main working language of the legal system is English.

The principal court is the Royal Court, with appeals to the Jersey Court of Appeal and, ultimately, to the Judicial Committee of the Privy Council. The Bailiff is head of the judiciary; the Bailiff and the Deputy Bailiff are appointed by the Crown. Other members of the island's judiciary are appointed by the Bailiff. The convening of the Assize d'Heritage is that of the Royal Court of Jersey, the oldest surviving land court in Europe.
