names for the sea include (the Gaulish Ocean) which was used by
Isidore of Seville in the sixth century.
The term ''British Sea'' is still used by speakers of
Cornish and
Breton, with the sea known to them as and respectively. While it is likely that these names derive from the Latin term, it is possible that they predate the arrival of the Romans in the area. The
modern Welsh is often given as (the Lord's or Prince's Sea); however, this name originally described both the Channel and the
North Sea combined.
Anglo-Saxon texts make reference to the sea as (South Sea), but this term fell out of favour, as later English authors followed the same conventions as their Latin and Norman contemporaries. One English name that did persist was the ''Narrow Seas'', a collective term for the channel and
North Sea. As England (followed by Great Britain and the United Kingdom) claimed sovereignty over the sea, a Royal Navy Admiral was appointed with maintaining duties in the two seas. The office was maintained until 1822, when several European nations (including the United Kingdom) adopted a limit to territorial waters.

's description named the sea as ''Britanicus Oceanus nunc Canalites Anglie'' (Ocean of the Britons but now English Channel). The map is possibly the first recorded use of the term ''English Channel'' and the description suggests the name had recently been adopted.
In the sixteenth century, Dutch maps referred to the sea as the (English Channel) and by the 1590s, William Shakespeare used the word ''Channel'' in his history plays of Henry VI (play), Henry VI, suggesting that by that time, the name was popularly understood by English people.

Acts of Union 1707, this was replaced in official maps and documents with ''British Channel'' or ''British Sea'' for much of the next century. However, the term English Channel remained popular and was finally in official usage by the nineteenth century.

The French name has been used since at least the 17th century.
The name is usually said to refer to the sleeve () shape of the Channel.
Folk etymology has derived it from a
Celtic word meaning 'channel' that is also the source of the name for
the Minch in Scotland, but this name is not attested before the 17th century, and French and British sources of that time are clear about its etymology. The name in French has been directly adapted in other languages as either a
calque, such as in Italian or the ''Ärmelkanal'' in German, or a direct
borrowing, such as in Spanish.

defines the limits of the English Channel as:

The
Strait of Dover (), at the Channel's eastern end, is its narrowest point, while its widest point lies between
Lyme Bay and the Gulf of
Saint Malo, near its midpoint.
Well on the continental shelf, it has an average depth of about at its widest; yet averages about between
Dover and
Calais, its notable sandbank hazard being
Goodwin Sands. Eastwards from there the adjoining North Sea reduces to about across the
Broad Fourteens (14 fathoms) where it lies over the southern cusp of the former land bridge between
East Anglia and the
Low Countries. The North Sea reaches much greater depths east of northern Britain. The Channel descends briefly to in the submerged valley of
Hurd's Deep, west-northwest of
Guernsey.

There are several major islands in the Channel, the most notable being the
Isle of Wight off the English coast, and the
Channel Islands, British
Crown Dependencies off the coast of France. The coastline, particularly on the French shore, is deeply indented, with several small islands close to the coastline, including
Chausey and
Mont-Saint-Michel. The
Cotentin Peninsula on the French coast juts out into the Channel, with the wide Bay of the Seine () to its east. On the English side there is a small parallel
strait, the
Solent, between the Isle of Wight and the mainland. The
Celtic Sea is to the west of the Channel.
The Channel acts as a funnel that amplifies the tidal range from less than a metre at sea in eastern places to more than 6 metres in the
Channel Islands, the west coast of the
Cotentin Peninsula and the north coast of
Brittany in monthly
spring tides. The time difference of about six hours between high water at the eastern and western limits of the Channel is indicative of the
tidal range being amplified further by
resonance. Amphidromic points are the
Bay of Biscay and varying more in precise location in the far south of the North Sea, meaning both those associated eastern coasts repel the tides effectively, leaving the Strait of Dover as every six hours the natural bottleneck short of its consequent gravity-induced repulsion of the southward tide (surge) of the North Sea (equally from the Atlantic). The Channel does not experience, but its existence is necessary to explain the extent of
North Sea storm surges, such as necessitate the
Thames Barrier,
Delta Works,
Zuiderzee works (
Afsluitdijk and other dams).

Geological origins
The full English Channel connecting the
North Sea to the
Western Atlantic via the
Strait of Dover is of geologically recent origin, having formed late in the
Pleistocene period. The English Channel first developed as an arm of the Atlantic Ocean during the
Pliocene period (5.3-2.6 million years ago) as a result of differential
tectonic uplift along pre-existing tectonic weaknesses during the
Oligocene

, linked by an unbroken
Weald–Artois anticline, a ridge running between the Dover and Calais regions. During Pleistocene glacial periods this ridge acted as a natural dam holding back a large freshwater
pro-glacial lake in the
Doggerland region, now submerged under the
North Sea. During this period, the North Sea and almost all of the British Isles were covered by ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian
ice sheets that joined to the north, blocking its exit. The sea level was about lower than it is today. Then, between 450,000 and 180,000 years ago, at least two catastrophic
glacial lake outburst floods breached the Weald–Artois anticline. These contributed to creating some of the deepest parts of the channel such as
Hurd's Deep.
The first flood of 450,000 years ago would have lasted for several months, releasing as much as one million cubic metres of water per second.
[
*] The flood started with large but localised waterfalls over the ridge, which excavated depressions now known as the ''Fosses
Dangeard''. The flow eroded the retaining ridge, causing the rock dam to fail and releasing lake water into the Atlantic. After multiple episodes of changing sea level, during which the ''Fosses Dangeard'' were largely infilled by various layers of sediment, another catastrophic flood some 180,000 years ago carved a large bedrock-floored valley, the
Lobourg Channel, some 500 m wide and 25 m deep, from the southern North Sea basin through the centre of the
Straits of Dover and into the English Channel.
It left streamlined islands, longitudinal erosional grooves, and other features characteristic of catastrophic
megaflood events, still present on the sea floor and now revealed by high-resolution sonar. Through the scoured channel passed a river, the
Channel River, which drained the combined

, although a land connection across the southern
North Sea would have existed intermittently at later times when periods of
glaciation resulted in lowering of sea levels.
During
interglacial periods (when sea levels were high) between the initial flooding 450,000 years ago until around 180,000 years ago, the Channel would still have been separated from the North Sea by a land bridge to the north of the Strait of Dover (the Strait of Dover at this time formed part of a
estuary fed by the Thames and
Scheldt), restricting interchange of marine fauna between the Channel and the North Sea (except perhaps by occasional overtopping). During the
Last Interglacial/Eemian (115–130,000 years ago) the connection between the North Sea and the English Channel was fully open as it is today, resulting in Britain being an island during this interval, before lowered sea levels reconnected it to the continent during the
Last Glacial Period. From the end of the Last Glacial Period, to the beginning of the Holocene rising sea levels again resulted in the unimpeded connection between the North Sea and the English Channel resuming due to the sinking of
Doggerland, with Britain again becoming an island.
Ecology
As a busy shipping lane, the Channel experiences environmental problems following accidents involving ships with toxic cargo and oil spills. Indeed, over 40% of the UK incidents threatening pollution occur in or very near the Channel. One occurrence was the
MSC ''Napoli'', which on 18 January 2007 was beached with nearly 1700 tonnes of dangerous cargo in Lyme Bay, a protected World Heritage Site coastline. The ship had been damaged and was en route to
Portland Harbour.
The English Channel, despite being a busy shipping lane, remains in part a haven for wildlife. Atlantic oceanic species are more common in the westernmost parts of the channel, particularly to the west of
Start Point, Devon, but can sometimes be found further east towards Dorset and the Isle of Wight. Seal sightings are becoming more common along the English Channel, with both
grey seal and
harbour seal recorded frequently.
Human history
The Channel is thought to have prevented

from colonising Britain during the Last Interglacial/Eemian, though they returned to Britain during the Last Glacial Period when sea levels were lower. The Channel has in historic times been both an easy entry for seafaring people and a key natural defence, halting invading armies while in conjunction with control of the North Sea allowing Britain to blockade the continent. The most significant failed invasion threats came when the Dutch and Belgian ports were held by a major continental power, e.g. from the
Spanish Armada in 1588,

. For the next 250 years the Scandinavian raiders of Norway, Sweden, and Denmark dominated the North Sea, raiding monasteries, homes, and towns along the coast and along the rivers that ran inland. According to the ''
Anglo-Saxon Chronicle'' they began to settle in Britain in 851. They continued to settle in the
British Isles and the continent until around 1050, with some raids recorded along the channel coast of England, including at Wareham, Portland, near Weymouth and along the river Teign in Devon.
The
fiefdom of Normandy was created for the
Viking leader
Rollo (also known as Robert of Normandy). Rollo had besieged Paris but in 911 entered
vassalage to the king of the
West Franks Charles the Simple through the
Treaty of St.-Claire-sur-Epte. In exchange for his
homage and
fealty, Rollo legally gained the territory he and his Viking allies had previously conquered. The name "Normandy" reflects Rollo's Viking (i.e. "Northman") origins.

Mediterranean and the Orient.
Although the British surrendered claims to mainland Normandy and other French possessions in 1801, the monarch of the United Kingdom retains the title Duke of Normandy in respect to the Channel Islands. The Channel Islands (except for
Chausey) are
Crown Dependencies of the
British Crown. Thus the
Loyal toast in the Channel Islands is ''Le roi, notre Duc'' ("The King, our Duke"). The British monarch is understood to ''not'' be the Duke of Normandy in regards of the French region of Normandy described herein, by virtue of the

, English foreign policy concentrated on preventing invasion across the Channel by ensuring no major European power controlled the potential Dutch and Flemish invasion ports. Her climb to the pre-eminent
sea power of the world began in 1588 as the attempted invasion of the
Spanish Armada was defeated by the combination of outstanding naval tactics by the English and the Dutch under command of
Charles Howard, 1st Earl of Nottingham with
Sir Francis Drake second in command, and the following stormy weather. Over the centuries the
Royal Navy slowly grew to be the most powerful in the world.

was possible only because the
Royal Navy eventually managed to exercise unquestioned control over the seas around Europe, especially the Channel and the North Sea. During the
Seven Years' War, France attempted to
launch an invasion of Britain. To achieve this France needed to gain control of the Channel for several weeks, but was thwarted following the British naval victory at the
Battle of Quiberon Bay in 1759 and was unsuccessful (The last French landing on English soil being in 1690 with a raid on Teignmouth, although the last French raid on British soil was a raid on Fishguard, Wales in 1797).
Another significant challenge to British domination of the seas came during the
Napoleonic Wars

Admiral Fisher in the years before

. "Five keys lock up the world! Singapore, the Cape,
Alexandria, Gibraltar, Dover." However, on 25 July 1909
Louis Blériot made the first Channel crossing from
Calais to
Dover in an aeroplane. Blériot's crossing signalled a change in the function of the Channel as a barrier-moat for England against foreign enemies.
Because the ''
Kaiserliche Marine'' surface fleet could not match the British Grand Fleet, the Germans developed
submarine warfare, which was to become a far greater threat to Britain. The
Dover Patrol, set up just before the war started, escorted cross-Channel troopships and prevented submarines from sailing in the Channel, obliging them to travel to the Atlantic via the much longer route around Scotland.
On land, the
German army attempted to capture French Channel ports in the
Race to the Sea but although the trenches are often said to have stretched "from the frontier of Switzerland to the English Channel", they reached the coast at the North Sea. Much of the British war effort in
Flanders was a bloody but successful strategy to prevent the Germans reaching the Channel coast.
At the outset of the war, an attempt was made to block the path of
U-boats through the Dover Strait with
naval minefields. By February 1915, this had been augmented by a stretch of light steel netting called the
Dover Barrage, which it was hoped would ensnare submerged submarines. After initial success, the Germans learned how to pass through the barrage, aided by the unreliability of British mines. On 31 January 1917, the Germans resumed
unrestricted submarine warfare leading to dire Admiralty predictions that submarines would defeat Britain by November, the most dangerous situation Britain faced in either world war.
The
Battle of Passchendaele in 1917 was fought to reduce the threat by capturing the submarine bases on the Belgian coast, though it was the introduction of
convoys and not capture of the bases that averted defeat. In April 1918 the Dover Patrol carried out the
Zeebrugge Raid against the U-boat bases. During 1917, the Dover Barrage was re-sited with improved mines and more effective nets, aided by regular patrols by small warships equipped with powerful searchlights. A German attack on these vessels resulted in the
Battle of Dover Strait in 1917. A much more ambitious attempt to improve the barrage, by installing eight massive concrete towers across the strait was called the
Admiralty M-N Scheme but only two towers were nearing completion at the end of the war and the project was abandoned.
The naval blockade in the Channel and North Sea was one of the decisive factors in the German defeat in 1918.
Second World War

During the
Second World War, naval activity in the
European theatre was primarily
limited to the Atlantic. During the
Battle of France in May 1940, the
German forces succeeded in capturing both
Boulogne and
Calais, thereby threatening the line of retreat for the
British Expeditionary Force. By a combination of hard fighting and German indecision, the port of
Dunkirk was kept open allowing 338,000 Allied troops to be evacuated in
Operation Dynamo. More than 11,000 were evacuated from
Le Havre

during
Operation Cycle and a further 192,000 were evacuated from ports further down the coast in
Operation Aerial in June 1940. The early stages of the
Battle of Britain featured German air attacks on Channel shipping and ports; despite these early successes against shipping the Germans did not win the
air supremacy necessary for
Operation Sealion, the projected cross-Channel invasion.
The Channel subsequently became the stage for an intensive coastal war, featuring submarines,
minesweepers, and
Fast Attack Craft.

concentration camps;
partisan resistance and retribution; accusations of
collaboration; and slave labour (primarily Russians and eastern Europeans) being brought to the islands to build fortifications. The
Royal Navy blockaded the islands from time to time, particularly following the
liberation of mainland Normandy in 1944. Intense negotiations resulted in some
Red Cross humanitarian aid, but there was considerable hunger and privation during the occupation, particularly in the final months, when the population was close to starvation. The German troops on the islands surrendered on 9 May 1945, a day after the final surrender in mainland Europe.
English Channel migrant crossings (2018–present)

There is significant public concern in the UK about illegal immigrants coming on small boats from France. Since 2018, the English Channel has seen a major increase in number of crossing.
Population
The English Channel coast is far more densely populated on the English shore. The most significant towns and cities along both the English and French sides of the Channel (each with more than 20,000 inhabitants, ranked in descending order; populations are the urban area populations from the 1999 French census, 2001 UK census, and 2001

Economy
Shipping
The Channel has traffic on both the UK–Europe and North Sea–Atlantic routes, and is the world's busiest seaway, with over 500 ships per day. Following an accident in January 1971 and a series of disastrous collisions with wreckage in February, the Dover TSS, the world's first
radar

-controlled
traffic separation scheme, was set up by the
International Maritime Organization. The scheme mandates that vessels travelling north must use the French side, travelling south the English side. There is a separation zone between the two lanes.
In December 2002 the
MV ''Tricolor'', carrying £30m of luxury cars, sank northwest of Dunkirk after collision in fog with the container ship ''Kariba''. The cargo ship ''Nicola'' ran into the wreckage the next day. There was no loss of life.

The shore-based long-range traffic control system was updated in 2003 and there is a series of traffic separation systems in operation. Though the system is inherently incapable of reaching the levels of safety obtained from aviation systems such as the
traffic collision avoidance system, it has reduced accidents to one or two per year.
Marine
GPS systems allow ships to be preprogrammed to follow navigational channels accurately and automatically, further avoiding risk of running aground, but following the fatal collision between Dutch Aquamarine and Ash in October 2001, Britain's
Marine Accident Investigation Branch (MAIB) issued a safety bulletin saying it believed that in these most unusual circumstances GPS use had actually contributed to the collision. The ships were maintaining a very precise automated course, one directly behind the other, rather than making use of the full width of the traffic lanes as a human navigator would.
A combination of radar difficulties in monitoring areas near cliffs, a failure of a CCTV system, incorrect operation of the anchor, the inability of the crew to follow standard procedures of using a GPS to provide early warning of the ship dragging the anchor and reluctance to admit the mistake and start the engine led to the MV ''Willy'' running aground in
Cawsand Bay,
Cornwall, in January 2002. The MAIB report makes it clear that the harbour controllers were informed of impending disaster by shore observers before the crew were themselves aware. The village of
Kingsand was evacuated for three days because of the risk of explosion, and the ship was stranded for 11 days.

Channel Tunnel
Many travellers cross beneath the Channel using the Channel Tunnel, first proposed in the early 19th century and finally opened in 1994, connecting the UK and France by rail. It is now routine to travel between Paris or
Brussels and London on the
Eurostar train. Freight trains also use the tunnel. Cars, coaches and lorries are carried on
Eurotunnel Shuttle trains between
Folkestone and
Calais.
Tourism

The coastal resorts of the Channel, such as
Brighton and
Deauville, inaugurated an era of aristocratic tourism in the early 19th century. Short trips across the Channel for leisure purposes are often referred to as
Channel Hopping.
Renewable energy
The
Rampion Wind Farm is an offshore wind farm located in the Channel, off the coast of
West Sussex. Other offshore wind farms planned on the French side of the Channel.
History of Channel crossings
As one of the narrowest and most well-known international waterways lacking dangerous currents, the Channel has been the first objective of numerous innovative sea, air, and
human powered crossing technologies.
Pre-historic people sailed from the mainland to England for millennia. At the end of the
last Ice Age, lower sea levels even permitted
walking across.
By boat
Pierre Andriel crossed the English Channel aboard the ''
Élise'', ex the Scottish p.s. "Margery" in March 1816, one of the earliest seagoing voyages by
steam ship.
The paddle steamer ''Defiance'', Captain William Wager, was the first steamer to cross the Channel to Holland, arriving there on 9 May 1816.
On 10 June 1821, English-built
paddle steamer ''Rob Roy'' was the first passenger ferry to cross channel. The steamer was purchased subsequently by the French postal administration and renamed ''Henri IV'' and put into regular passenger service a year later. It was able to make the journey across the Straits of Dover in around three hours.
In June 1843, because of difficulties with Dover harbour, the South Eastern Railway company developed the
Boulogne-sur-Mer-
Folkestone route as an alternative to Calais-Dover. The first ferry crossed under the command of
Captain Hayward.
In 1974 a Welsh coracle piloted by Bernard Thomas of Llechryd crossed the English Channel to France in 13 hours. The journey was undertaken to demonstrate how the
Bull Boats of the
Mandan Indians of
North Dakota could have been copied from coracles introduced by
Prince Madog in the 12th century.
The
Mountbatten class hovercraft (MCH) entered commercial service in August 1968, initially between Dover and Boulogne but later also
Ramsgate (
Pegwell Bay) to Calais. The journey time Dover to Boulogne was roughly 35 minutes, with six trips per day at peak times. The fastest crossing of the English Channel by a commercial car-carrying hovercraft was 22 minutes, recorded by the ''Princess Anne'' MCH SR-N4 Mk3 on 14 September 1995,
By air
The first aircraft to cross the Channel was a
balloon in 1785, piloted by
Jean Pierre François Blanchard (France) and
John Jeffries (US).

Louis Blériot (France) piloted the first aeroplane to cross in 1909.
On 26 September 2008, Swiss
Yves Rossy aka ''Jetman'' became the first person to cross the English Channel with a
Jet Powered Wing,
He jumped from a
Pilatus Porter over
Calais, France, Rossy crossed the English Channel where he deployed his parachute and landed in
Dover
The first
flying car to have crossed the English Channel is a Pégase designed by the French company Vaylon on 14 June 2017. It was piloted by a Franco-Italian pilot Bruno Vezzoli. This crossing was carried out as part of the first road and air trip from Paris to London in a flying car. Pegase is a 2 seats road approved dune buggy and a
powered paraglider. The takeoff was at 8:03 a.m. from
Ambleteuse in the North of France and landing was at East Studdal, near Dover. The flight was completed in 1 hour and 15 minutes for a total distance covered of including over the English Channel at an altitude of .
On 12 June 1979, the first
human-powered aircraft to cross the English Channel was the ''
Gossamer Albatross'', built by American
aeronautical engineer Dr.
Paul B. MacCready's company
AeroVironment, and piloted by
Bryan Allen. The crossing was completed in 2 hours and 49 minutes.
On 4 August 2019, Frenchman
Franky Zapata became the first person to cross the English Channel on a jet-powered
Flyboard Air. The board was powered by a kerosene-filled backpack. Zapata made the journey in 22 minutes, having landed on a boat half-way across to refuel.
By swimming
The sport of Channel swimming traces its origins to the latter part of the 19th century when Captain
Matthew Webb made the first observed and unassisted swim across the Strait of Dover, swimming from England to France on 24–25 August 1875 in 21 hours 45 minutes.
Up to 1927, fewer than ten swimmers (including the first woman,
Gertrude Ederle in 1926) had managed to successfully swim the English Channel, and many dubious claims had been made. The Channel Swimming Association (CSA) was founded to authenticate and ratify swimmers' claims to have swum the Channel and to verify crossing times. The CSA was dissolved in 1999 and was succeeded by two separate organisations: CSA Ltd (CSA) and the Channel Swimming and Piloting Federation (CSPF), both observe and authenticate cross-Channel swims in the Strait of Dover. The Channel Crossing Association was also set up to cater for unorthodox crossings.
The team with the most Channel swims to its credit is the
Serpentine Swimming Club in London, followed by the international
Sri Chinmoy Marathon Team.
As of 2023, 1,881 people had completed 2,428 verified solo crossings under the rules of the CSA and the CSPF. This includes 24 two-way crossings and three three-way crossings.
The Strait of Dover is the busiest stretch of water in the world. It is governed by International Law as described in ''Unorthodox Crossing of the Dover Strait Traffic Separation Scheme''. It states: "
nexceptional cases the French Maritime Authorities may grant authority for unorthodox craft to cross French territorial waters within the Traffic Separation Scheme when these craft set off from the British coast, on condition that the request for authorisation is sent to them with the opinion of the British Maritime Authorities."
The fastest verified swim of the Channel was by the Australian
Trent Grimsey on 8 September 2012, in 6 hours 55 minutes,
beating a swim of 2007. The female record is held by
Yvetta Hlavacova of Czechia, on 7 hours, 25 minutes on 5 August 2006.
[ Both records were from England to France.][
There may have been some unreported swims of the Channel, by people intent on entering Britain in circumvention of immigration controls. A failed attempt to cross the Channel by two Syrian refugees in October 2014 came to light when their bodies were discovered on the shores of the North Sea in Norway and the Netherlands.

By car
On 16 September 1965, two Amphicars crossed from Dover to Calais.[Autocar article entitled Cars Ahoy published 10 December 1965]
Other types
PLUTO was war-time fuel delivery project of "pipelines under the ocean" from England to France. Though plagued with technical difficulties during the Battle of Normandy, the pipelines delivered about 8% of the fuel requirements of the Allied forces between D-Day and VE-Day.
