How Jersey kept the law of a duchy England lost
3 070 words · 14 min · updated 2026-09-26
Jersey kept Norman law after 1204 because the English crown went on claiming the Duchy of Normandy until 1259, and English law in the islands would have weakened that claim. Philip Augustus took the mainland duchy in 1204; the Channel Islands stayed with King John, and their courts were set up as Norman courts, with a Bailiff and twelve jurats applying Norman custom. The claim was given up in 1259. The institutions built to support it were kept, and eight centuries of Jersey's history, from the royal charters of the fourteenth century to the Bailiff handing the island to German forces on 1 July 1940, run through them.

How Jersey became part of Normandy
Neanderthal hunters used the caves at La Cotte de St Brelade as a base about 250,000 years ago, when mammoth and woolly rhinoceros crossed ground the sea had not yet cut off. Rising sea levels made Jersey an island around 6,000 years ago. The Neolithic communities that followed built dolmens, and the scale of La Hougue Bie suggests that its builders organised labour across a wider area than the island, including the surrounding coasts. Trade already ran to Brittany and to the south coast of England.
Metal detectorists announced in June 2012 that they had found about 70,000 late Iron Age and Roman coins, a hoard thought to have belonged to members of the Curiosolitae fleeing the armies of Julius Caesar around 50 to 60 BC. No evidence of a Roman occupation of the island has been found, although coins and a probable Gallo-Roman temple site at Le Pinacle show Roman influence.
Even the island's Latin name is argued over. Tradition identifies Jersey with the Caesarea of the Antonine Itinerary; others place Caesarea in the Scilly Isles and give Jersey the name Andium, which the island's social housing corporation now carries.
Jersey was politically linked to Brittany until around 933, when William Longsword, Duke of Normandy, seized it. The Norman legal system adopted then is still the basis of Jersey law. Rural life was organised by two units that outlasted the duchy: the fief, of which an estimated 245 existed at one time or another between the twelfth and twentieth centuries, and the parish, whose boundaries were fixed by Norman times and have changed little since. The de Carteret family held the fief of St Ouen, the senior fief on the island, by 1135.
When Duke William defeated Harold Godwinson at Hastings in 1066, he ruled Jersey as part of Normandy and England as a separate kingdom. The island reached the English crown through the duchy, and the Rolls of the Norman Exchequer for 1180 divide it into three administrative ministeria.
Why the English crown kept Norman law in Jersey
King John lost continental Normandy to Philip Augustus of France in 1204. French forces held the Channel Islands from 1204 to 1206 and again from 1216 to 1217, and both times the English crown recovered them. Pierre de Préaux, a governor of Rouen who held the islands, chose to support John, and the islands passed into the personal possession of the English king as a Peculiar of the Crown.
Who made that choice is disputed. Jersey Finance writes that the islands "were persuaded to side with King John". Policy Centre Jersey writes that it "was not the people of Jersey who made this decision", and places it within the settlement between the English crown and the Norman dukes. Tradition credits the island's autonomy to the Constitutions of King John; historians question that document, and the Wikipedia account of the island describes the self-government as resting on a succession of royal charters and conventions, with its precise origin still debated.
The legal reasoning is better recorded. John, and Henry III after him, kept the title of Duke of Normandy until 1259. Courts established on English law would have treated the islands as English territory and undercut the ducal claim, so the islands' courts were founded as Norman courts, applying Norman custom such as the Coutumier de Normandie. Justice was conducted by twelve jurats, the connétables and a bailiff. Jersey received its own Bailiff in the late 1270s, and from the 1290s the Bailiff took justice while the Warden kept taxation and defence. That division, probably meant as a temporary arrangement, became the separation of Crown and justice the island still runs on.
The Treaty of Paris of 1259 ended the claim on both sides: the French king gave up the islands, and the English king gave up mainland Normandy. The Channel Islands were never absorbed into the Kingdom of England. The land settlement followed the same line. An inquest into the loyalty of Jersey landowners found that most held their main estates on the mainland; most of them gave up their island land to keep their French estates, the de Carterets stayed, and a new landowning class drawn from royal officials came to think of itself as islanders.
The crown still uses the title. A 2025 House of Commons briefing paper, quoted by Policy Centre Jersey, notes that the Channel Islands owe allegiance to the monarch as Duke of Normandy, a title Henry III renounced in 1259 and removed from his seal in 1260.
How royal charters bought a frontier island's loyalty
The new border put Jersey on the front line of the Anglo-French wars for the rest of the Middle Ages. After raids by Eustace the Monk, Warden de Suligny built a royal fortress at Gorey, Mont Orgueil, which became the island's defence of last resort. Jersey was attacked in 1294, and a raid by the Scots king David Bruce in 1336 led to an island militia, formed in 1337 and compulsory for all men of military age for the next 600 years.
The Hundred Years' War brought the French in person. Admiral Béhuchet landed in March 1338 and stayed until September; the island was overrun and Mont Orgueil held. In 1339 the French returned, reportedly with 8,000 men, and their commander Robert Bertrand promised islanders the ancient liberties the English king had not recently ratified. Some senior islanders were pro-French at the time. The castle held again.
Edward III answered in 1341, declaring that Jerseymen should "hold and retain all privileges, liberties, immunities and customs" granted by his predecessors. Policy Centre Jersey describes the charters that followed as a special status granted because of an almost permanent state of tension between England and France: goods from the islands entered England free of duty, islanders entered England without restriction, and military spending on the island continued into the mid-nineteenth century.
| Year | Pressure from France | What the crown granted or confirmed |
|---|---|---|
| 1338 to 1339 | Béhuchet and Bertrand overrun the island | Charter of privileges, 1341 |
| 1373 | Du Guesclin besieges Mont Orgueil | |
| 1394 | Richard II seeks peace with France | Exemption from tolls, duties and customs in England |
| 1399 | War resumes under Henry IV | Charters renewed |
| 1406 | Pero Niño lands in St Aubin's Bay | |
| 1461 to 1468 | French forces hold Mont Orgueil | Separate charters for Jersey and Guernsey, 1469 |
Richard II came close to recognising the islands as part of Normandy in the 1390s, and the usurpation of Henry IV in 1399 interrupted it. On 7 October 1406, 1,000 French men at arms under the Castilian corsair Pero Niño defeated 3,000 defenders; they left on 9 October with a ransom. The longest occupation came during the Wars of the Roses, when Margaret of Anjou's bargain for French support let French forces take Mont Orgueil in 1461. They held Jersey until Yorkist forces and the militia recaptured the castle in 1468, and the States Assembly may have taken shape during those seven years, when the occupying commander ordered an assize and set rules for choosing jurats. Edward IV issued separate charters of privilege for Jersey and Guernsey in 1469.
Who governed Jersey after the Bailiff and Governor divided
The Reformation arrived through the English crown and was shaped by French refugees. Under Elizabeth I, Huguenot immigrants established Calvinism, a school opened in every parish, and Sir Walter Raleigh, as governor, named the new Elizabeth Castle after the queen. The crown also offered representation once. In 1541 the Privy Council intended to give Jersey two seats in Parliament, but the letter instructing the jurats to send two burgesses reached the States on the day the members were due in London, and the idea went no further.
The constitutional turning point came from a quarrel over appointments. Governor Sir John Peyton claimed the right to appoint the Bailiff; Jean Hérault, appointed by the king in 1615, claimed the Bailiff was the island's real head of government. On 18 February 1617 the Privy Council declared that the "charge of military forces be wholly in the Governor, and the care of justice and civil affairs in the Bailiff". That order is still the precedent that keeps the Lieutenant-Governor out of domestic affairs.
The civil wars divided the island. Islanders' sympathies lay with Parliament, while the de Carteret family held Jersey for the king, and on 17 February 1649 Charles II was proclaimed king in the Royal Square in St Helier. Parliamentarian forces captured the island in 1651. The Commonwealth then tried to do what the Norman claim had once prevented: in 1652 Parliament treated Jersey as an English county, and in 1653 an Instrument provided for one member in the House of Commons. The States did not meet at all during the nine years of the Commonwealth.
The Restoration reversed it. Charles II gave Sir George Carteret, Bailiff and governor, a grant of land in the American colonies that became New Jersey, and presented the island with a royal mace as a "perpetual remembrance" of its fidelity. The mace has been carried before the Bailiff at sittings of the Royal Court and the States ever since, including during the German occupation.
How the States took lawmaking from the Royal Court
Until 1771 two bodies made law in Jersey, the States and the Royal Court. A devaluation of the liard in 1729 provoked riots that forced its cancellation. On 28 September 1769, during a corn shortage, men from the northern parishes marched into St Helier and broke into the Royal Court. The Privy Council sent five companies of Royal Scots, who heard the grievances, and the crown issued the Code of 1771, which codified the island's laws and gave the States the sole power to legislate.
Party politics followed. Jean Dumaresq, who wanted a democratically elected States holding executive power, led the Magots against the Charlots, and the two camps became the Rose and Laurel parties of the next century. The last French invasion came on 6 January 1781, when Baron de Rullecourt captured St Helier at dawn and was defeated by a British force under Major Francis Peirson in the Battle of Jersey.
Peace after 1815 changed the argument. With the conflicts between Britain and its rivals moving to the North Sea, the Channel Islands' defence costs, £500,000 a year even in peacetime after 1815, led to open questions about the utility of keeping them. The paddle steamer Medina reached Jersey on 11 June 1823, weekly services to England followed from 1824, and by 1840 there were 5,000 English residents. The population rose from 47,544 in 1841 to 56,078 in 1861.
Newcomers brought demands to make the island English. Abraham Le Cras argued that the States had no power to legislate at all, and in 1852 the Privy Council issued three Orders in Council creating new courts and a paid police force for St Helier. Both island parties opposed them, around 7,000 islanders signed a petition, and by 1854 the orders were revoked on condition that the States pass most of the reforms itself. On 6 November 1856 the States voted to add 14 deputies, and the first of them were elected on 12 January 1857. The island moved to the pound sterling in 1837, English was first permitted in States debates in 1901, and in 1923 the States refused a British request for an annual contribution to the costs of the Empire, offering and paying a one-off sum instead.
What the German occupation asked of the Bailiff
How the island was handed over
On 19 June 1940 the British government declared the Channel Islands a demilitarised zone. The garrison was withdrawn, the Lieutenant-Governor was recalled, and the militia volunteered as one to join the forces in England. Evacuation was voluntary. On 28 June German aircraft bombed and machine-gunned the island, and on 1 July German forces arrived at the airport, where the Bailiff, Alexander Coutanche, who had been made Civil Governor, formally handed over control.
The Government of Jersey, Jersey Heritage and Wikipedia give different figures for those weeks.
| Measure | Government of Jersey | Jersey Heritage | Wikipedia |
|---|---|---|---|
| Evacuated to Britain, June 1940 | About 6,500 | About 6,600 | About 8,000 (History of Jersey); 6,500 (Jersey) |
| Remaining when German forces landed, 1 July 1940 | About 40,000 | About 41,000 | |
| Killed in the air raid of 28 June 1940 | 10 | 11 | |
| German troops, 1940 to 1945 | About 2,000 at first, as many as 15,000 at one time | About 1,750 at first, 11,500 after the first year |
A States regulation of 27 June 1940 merged the executive committees into eight departments, whose presidents and the Crown officers formed the Superior Council under the Bailiff. The chain of approval changed. In peacetime Jersey's laws required the sanction of the monarch; under occupation every law, order and regulation went first to the German commandant. The States still met to pass the annual budget, and the island's courts tried most civil and criminal cases.
What the occupation cost
From 1941 the Organisation Todt brought around 6,000 enslaved and forced labourers to fortify the island, among them an estimated 1,500 Soviet prisoners of war and 2,000 Spanish Republicans; Jersey Heritage records the deaths of 116 of them. The occupiers laid 67,000 land mines. Wireless sets were confiscated in June 1942, and in September 1942 an order from Hitler sent about 1,200 people not born in the island to internment camps in Germany, in reprisal for the British internment of German civilians in Persia in 1941.
Resistance took the form of hidden radios, copied news sheets and sheltered fugitives. Canon Clifford Cohu cycled through St Helier calling out the BBC news and died in German custody in September 1944. Louisa Gould hid an escaped Soviet labourer, Fyodor Burriy, was betrayed by a neighbour and died in a Nazi camp in 1945. Her brother Harold Le Druillenec survived Bergen-Belsen. Albert Bedane sheltered a Jewish woman for two years and was recognised as Righteous Among the Nations in 2000. Twenty-one islanders who died in Nazi prisons and camps are named on the Lighthouse Memorial on the New North Quay, and about 152 people tried to escape by sea in the final months, nine of whom are known to have drowned.
After D-Day the island was cut off from France. Gas and electricity failed, and the Swedish Red Cross ship Vega arrived on 31 December 1944 with 750 tons of parcels and medicine, and made five further visits. Jersey was liberated on 9 May 1945, when HMS Beagle arrived; Coutanche went out to the ship with the German commander for the surrender. The island came out of the war £7.75 million in debt, and 9 May is still its public holiday.
Why the occupation record is still argued over
The civil government stood between the occupiers and the islanders, and how far it went is contested. In October 1940 the island authorities complied with the German order to register Jews, and registration cards were marked with a red J; across the islands 18 Jews registered out of an estimated 30 to 50. Officials also refused to require yellow stars, and some procured false documents. The release of wartime archives in the 1990s and Madeleine Bunting's book The Model Occupation reopened the question, and its argument that islanders "settled down" to the occupation drew anger on the islands. Norman Le Brocq, a leader of the Jersey resistance, accused the island's police and government of going unpunished for reporting Jews to the Germans. Jersey Heritage describes Coutanche as a buffer between occupiers and civilians and quotes an assessment of him as a "versatile, clever administrator". By November 1946 the Home Secretary told the House of Commons that most allegations of collaboration lacked substance; 12 cases were considered, and the Director of Public Prosecutions ruled out proceedings.
What Jersey rebuilt after the liberation
Liberation brought constitutional reform. A Jersey Evening Post poll after liberation found 88 of the 1,784 people surveyed in favour of keeping the rectors in the States. The franchise was extended to all British adults, and on 8 December 1945 Ivy Forster became the first woman elected to the States. The 1948 reform removed the jurats from the assembly, confined them to the Royal Court, replaced them with 12 senators, removed all rectors except the Dean, who lost his vote, and raised the number of deputies to 28.
The militia was abolished, the military establishments passed to the island, and for the first time since Edward III there was no permanent military presence in Jersey. The International Court of Justice ruled for British ownership of the Minquiers and the Ecréhous, reefs France had claimed. The census of 1945 counted 44,382 residents; there were 50,749 in 1946, and 103,267 on 21 March 2021.
Tourism, the island's principal industry for much of the post-war period, brought over 1,000,000 visits in 1997 and an estimated 526,500 in 2023. The finance industry grew from the 1960s onwards, and the debate over whether Jersey is a tax haven grew with it. Jèrriais, which islanders had used during the occupation to pass messages the Germans could not follow, declined quickly after 1945; children who spoke it at school in the 1940s and 1950s were forbidden to.
The Norman offices were kept through later reforms. The States of Jersey Law 2005 introduced ministerial government and removed the Bailiff's power of dissent and casting vote together with the Lieutenant-Governor's veto. A framework agreed with the British government in 2007 recognised that Jersey has an international identity different from that of the UK. The Bailiff still presides over the States, the Viscount still carries the mace in before the Bailiff, and at the start of each meeting members answer the roll call in French.

Common questions
Questions about Jersey
Why does the monarch hold the title Duke of Normandy in Jersey?
The islands reached the English crown through the Norman dukes, and when mainland Normandy was lost in 1204 the Channel Islands stayed. The title survives as a form of allegiance. A 2025 House of Commons briefing paper notes that Henry III renounced the ducal title in 1259 and removed it from his seal in 1260.
Did Jersey ever have seats in the English Parliament?
No. The Privy Council intended to give the island two seats in 1541, but the letter asking for two burgesses reached the States on the day they were due in London. In 1653, under the Commonwealth, an Instrument provided for one member in the House of Commons; it lapsed with the Restoration. Jersey has never been represented at Westminster.
How is New Jersey connected to Jersey?
Sir George Carteret, Bailiff and governor of Jersey, held the island for the royalist side in the civil wars. After the Restoration Charles II rewarded him with a large grant of land in the American colonies, between the Hudson and Delaware rivers, and Carteret named it New Jersey.
What was the Battle of Jersey?
The last French attempt on the island. On 6 January 1781, during the American War of Independence, a force under Baron de Rullecourt captured St Helier in a dawn raid and was then defeated by a British army under Major Francis Peirson. An earlier attempt, by the Prince of Nassau-Siegen in 1779, had been stopped from landing at St Ouen's Bay.
What did the Red Cross ship Vega bring to Jersey?
Food and medicine, at the point when the island was cut off from France after D-Day. The Swedish ship arrived on 31 December 1944 carrying 750 tons of supplies, and each islander received a parcel. The Vega returned five more times before and after the liberation of 9 May 1945.
