100-770: It is also approximately analogous to the Warthe and Saalian stages in northern Europe; the Riss glaciation in the Alps ; and the Illinoian Stage in North America. The colder last part from around 194,000 years ago is called the Penultimate Glacial Period . It is equivalent to Marine isotope stages (MIS) 10 through 6. MIS 10, 8 and 6 were glacial periods and 9 and 7 were interglacials . It

Arabic geographies, including the Kitāb az-Zīj of al-Battānī , mention

300-736: A Catholic king pushing for religious tolerance in opposition to a Protestant parliament in England. The king's army was defeated at the Battle of the Boyne and at the militarily crucial Battle of Aughrim in Ireland. Resistance held out, eventually forcing the guarantee of religious tolerance in the Treaty of Limerick . However, the terms were never honoured and a new monarchy was installed. The Kingdoms of England and Scotland were unified in 1707 creating

400-521: A complex geology that records a huge and varied span of Earth's history. Of particular note was the Caledonian orogeny during the Ordovician and early Silurian periods, when the craton Baltica collided with the terrane Avalonia to form the mountains and hills in northern Britain and Ireland. Baltica formed roughly the north-western half of Ireland and Scotland. Further collisions caused

500-406: A mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the north-western European mainland . There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated primarily from Great Britain. The only window when this could have occurred was prior to

600-731: A number of unusual arrangements between the Republic of Ireland, Northern Ireland and the United Kingdom. For example, citizens of Northern Ireland are entitled to the choice of Irish or British citizenship or both, and the Governments of Ireland and the United Kingdom consult on matters not devolved to the Northern Ireland Executive . The Northern Ireland Executive and the Government of Ireland also meet as

700-544: A problem until the 17th century. By the 18th century, most of Britain's forests were consumed for shipbuilding or manufacturing charcoal and the nation was forced to import lumber from Scandinavia, North America, and the Baltic. Most forest land in Ireland is maintained by state forestation programmes. Almost all land outside urban areas is farmland. However, relatively large areas of forest remain in east and north Scotland and in southeast England. Oak, elm, ash and beech are amongst

800-517: A similar nature. Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin , Cork , Limerick , Waterford and Wexford . England, however, was slowly conquered around

900-599: A single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies . The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the dispersal of some of the islands' population and culture throughout the world, and rapid depopulation of Ireland in the second half of

Domestic animals include the Connemara pony, Shetland pony, English Mastiff, Irish wolfhound and many varieties of cattle and sheep. England has a generally high population density, with almost 80% of the total population of the islands. Elsewhere in Great Britain and Ireland, high density of population

1300-739: Is coeval with the global Penultimate Glacial Period . The Saalian succeeded the Holstein interglacial and was followed by the Eemian interglacial (which began around 130,000 years ago) Though the start date of the Saalian was historically controversial, recent scholarship has suggested that the start date of the Saalian (and thus the end of the Holstein) is around 400,000 years ago. The Saalian encompasses multiple glacial cycles separated by interglacial periods. The first cold phase (Fuhne glacial) at

1400-788: Is limited to areas around a few large cities. The largest urban area by far is the Greater London Built-up Area with 9 million inhabitants. Other major population centres include the Greater Manchester Built-up Area (2.4 million), West Midlands conurbation (2.4 million) and West Yorkshire Urban Area (1.6 million) in England, Greater Glasgow (1.2 million) in Scotland and Greater Dublin Area (1.9 million) in Ireland. The population of England rose rapidly during

The Wolstonian Stage is a middle Pleistocene stage of the geological history of Earth that precedes the Ipswichian Stage ( Eemian Stage in Europe ) and follows the Hoxnian Stage in the British Isles. The Wolstonian Stage apparently includes three periods of glaciation. The Wolstonian Stage is temporally analogous to the Warthe Stage and Saalian Stage in northern Europe and

1600-525: The British Islands , not to be confused with the British Isles. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the north-west of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The topography of the islands is modest in scale by global standards. Ben Nevis ,

1700-721: The European beaver has been reintroduced in parts of Scotland. Wild boar have also been reintroduced to parts of southern England, following escapes from boar farms and illegal releases. Many rivers contain otters and grey and common seals are numerous on coasts. There are about 250 bird species regularly recorded in Great Britain, and another 350 that occur with varying degrees of rarity. The most numerous species are wren , robin , house sparrow , woodpigeon , chaffinch and blackbird . Farmland birds are declining in number, except for those kept for game such as pheasant , red-legged partridge , and red grouse . Fish are abundant in

1800-596: The Indo-European family . The Insular Celtic languages of the Goidelic sub-group ( Irish , Manx and Scottish Gaelic ) and the Brittonic sub-group ( Cornish , Welsh and Breton , spoken in north-western France ) are the only remaining Celtic languages —the last of their continental relations were extinct before the 7th century. The Norman languages of Guernésiais , Jèrriais and Sercquiais spoken in

1900-700: The Kingdom of Great Britain . Following an attempted republican revolution in Ireland in 1798 , the Kingdoms of Ireland and Great Britain were unified in 1801 , creating the United Kingdom . The Isle of Man and the Channel Islands remaining outside of the United Kingdom, but with their ultimate good governance being the responsibility of the British Crown (effectively the British government). Although

2000-655: The Late Middle Ages , Great Britain was separated into the Kingdom of England and Kingdom of Scotland, while control in Ireland fluxed between Gaelic kingdoms , Hiberno-Norman lords and the English-dominated Lordship of Ireland , soon restricted only to The Pale . The 1603 Union of the Crowns , Acts of Union 1707 and Acts of Union 1800 aimed to consolidate Great Britain and Ireland into

2100-667: The North/South Ministerial Council to develop policies common across the island of Ireland. These arrangements were made following the 1998 Good Friday Agreement . Another body established under the Good Friday Agreement, the British–Irish Council, is made up of all of the states and territories of the British Isles. The British–Irish Parliamentary Assembly ( Irish : Tionól Pharlaiminteach na Breataine agus na hÉireann ) predates

2200-710: The Northern Ireland Assembly , the States of Jersey , the States of Guernsey and the High Court of Tynwald (Isle of Man). The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to

2300-917: The Northwest German Plain , but older and exhibiting more surface weathering than the much later Young Drift areas of the Weichselian glaciation in northeast Germany. The areas last covered by the Saale cold period, roughly the Westphalian Bight , a large part of Lower Saxony and Saxony-Anhalt , south Brandenburg , or the Leipzig Bay and Lusatia in Saxony, are called the Old Drift Landscapes ( Altmoränenlandschaften ). They were further shaped and changed during

2400-590: The Quaternary Period , the most recent being the Devensian . As this ended, the central Irish Sea was deglaciated and the English Channel flooded, with sea levels rising to current levels some 8,000 years ago, leaving the British Isles in their current form. There are about 136 permanently inhabited islands in the group, the largest two being Great Britain and Ireland. Great Britain is to

The Channel Islands , off the north coast of France , are normally taken to be part of the British Isles, even though geographically they do not form part of the archipelago . Under the UK Interpretation Act 1978, the Channel Islands are clarified as forming part of

2600-657: The Riss glaciation in the Alps , and temporally equivalent to all of the Illinoian Stage and the youngest part of the Pre-Illinoian Stage in North America. It is contemporaneous with the North American Pre-Illinoian A, Early Illinoian, and Late Illinoian glaciations. The Wolstonian Stage is equivalent to Marine isotope stages 6 through 10. Britain became an Island during this period (350,000 years ago). It started 374,000 years ago and ended 130,000 years ago. The Wolstonian Stage

2700-500: The Tusker Tunnel between the ports of Rosslare and Fishguard proposed by The Institute of Engineers of Ireland in 2004. A rail tunnel was proposed in 1997 on a different route, between Dublin and Holyhead , by British engineering firm Symonds. Either tunnel, at 50 mi (80 km), would be by far the longest in the world, and would cost an estimated £15 billion or €20 billion. A proposal in 2007, estimated

From 1979 onwards, this was expanded to include the whole of Europe. London Heathrow Airport is Europe's busiest airport in terms of passenger traffic, and the Dublin-London route is the busiest air route in Europe collectively, the busiest route out of Heathrow and

2900-521: The Variscan orogeny in the Devonian and Carboniferous periods, forming the hills of Munster , south-west England, and southern Wales. Over the last 500 million years the land that forms the islands has drifted north-west from around 30°S, crossing the equator around 370 million years ago to reach its present northern latitude. The islands have been shaped by numerous glaciations during

It follows the Holstein interglacial ( Hoxnian Stage in Britain) and precedes the Eemian interglacial (globally known as the Last Interglacial and the Ipswichian in Britain), spanning from around 400,000 years ago to 130,000 years ago. The Saalian covers multiple glacial cycles punctuated by interglacial periods. In its latter part it

3100-477: The "P" of Pretannia to the "B" of Britannia by the Romans occurred during the time of Julius Caesar. Greco-Egyptian Claudius Ptolemy referred to the larger island as great Britain (μεγάλη Βρεττανία megale Brettania ) and to Ireland as little Britain (μικρὰ Βρεττανία mikra Brettania ) in his work Almagest (147–148 AD). According to Philip Freeman in 2001, Ptolemy "is the only ancient writer to use

Ireland for most of its history had much the same population density as Great Britain (about one-third of the total population). However, since the Great Irish Famine , the population of Ireland has fallen to less than one-tenth of

Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland. As a term, "British Isles" is a geographical name and not a political unit. In Ireland, the term is controversial , and there are objections to its usage. The Government of Ireland does not officially recognise

Viking invasions began in the 9th century, followed by more permanent settlements and political change, particularly in England. The Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. By

3500-1053: The Brettanic Isles as Brettanoi ". Strabo used Βρεττανική ( Brettanike ), and Marcian of Heraclea , in his Periplus maris exteri , used αἱ Πρεττανικαί νῆσοι ( the Prettanic Isles ) to refer to the islands. According to A. L. F. Rivet and Colin Smith in 1979 "the earliest instance of the name which is textually known to us" is in The Histories of Polybius , who referred to them as: αἱ Βρεταννικαί νήσοι , romanized :  hai Bretannikai nēsoi , lit.   'the Brettanic Islands' or 'the British Isles';. According to Rivet and Smith, this name encompassed "Britain with Ireland". According to Thomas O'Loughlin in 2018,

3600-442: The British Isles is mild, moist and changeable with abundant rainfall and a lack of temperature extremes. It is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of north-west Europe. The North Atlantic Drift ("Gulf Stream"), which flows from the Gulf of Mexico, brings with it significant moisture and raises temperatures 11 °C (20 °F) above

3700-407: The British Isles as twelve islands. John Skelton 's English translation of Diodorus Siculus's Bibliotheca historica , written in the middle 1480s, mentions the British Isles as the yles of Bretayne . Thomas Twyne 's English translation of Dionysius Periegetes 's Orbis descriptio , published in 1572, mentions the British Isles as the Iles of Britannia . The earliest citation of

3800-434: The British Isles was "a concept already present in the minds of those living in continental Europe since at least the 2nd–cent. CE". Historians today, though not in absolute agreement, largely agree that these Greek and Latin names were probably drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί ( Priteni or Pretani ). The shift from

3900-445: The British Isles were repeatedly submerged beneath an ice sheet which extended into the middle of the North Sea, with a larger ice sheet that covered a significant proportion of Scandinavia on the opposite side. Around 1.9 million years ago these two ice sheets frequently merged, essentially creating a land bridge between Scandinavia and northern Great Britain. Further south, there was a direct land bridge, now known as Doggerland , which

4000-403: The British Isles, the most prominent of which is association football. While this is organised separately in different national associations, leagues and national teams, even within the UK, it is a common passion in all parts of the islands. Rugby union is also widely enjoyed across the islands with four national teams from England , Ireland , Scotland and Wales . The British and Irish Lions

4100-400: The British Isles: Ireland and the United Kingdom of Great Britain and Northern Ireland .

Originally it comprised 25 members of the Oireachtas , the Irish parliament, and 25 members of the parliament of the United Kingdom , with the purpose of building mutual understanding between members of both legislatures. Since then the role and scope of the body has been expanded to include representatives from the Scottish Parliament , the Senedd (Welsh Parliament),

4400-437: The British–Irish Council's work. The United Kingdom and Ireland have separate media, although British television, newspapers and magazines are widely available in Ireland, giving people in Ireland a high level of familiarity with the culture of the United Kingdom. Irish newspapers are also available in the UK, and Irish state and private television are widely available in Northern Ireland. Certain reality TV shows have embraced

4500-420: The Channel Islands are similar to French, a language also spoken there. A cant , called Shelta , is spoken by Irish Travellers , often to conceal meaning from those outside the group. However, English, including Scots , is the dominant language, with few monoglots remaining in the other languages of the region. The Norn language of Orkney and Shetland became extinct around 1880. 2.5 million years ago

At the invitation of Diarmait Mac Murchada , a provincial king, and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom,

During the February 2008 meeting of the British–Irish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the British–Irish Council, the chair of the British–Irish Inter-Parliamentary Assembly, Niall Blaney , has suggested that the body should shadow

5000-446: The Hiberni and Picts. In time, Anglo-Saxon demands on the British became so great that they came to culturally dominate the bulk of southern Great Britain, though recent genetic evidence suggests Britons still formed the bulk of the population. This dominance created what is now England and left culturally British enclaves only in the north of what is now England , in Cornwall and what is now known as Wales. Ireland had been unaffected by

5100-407: The King of England from being vassal of the King of France . In 1534, King Henry VIII, at first having been a strong defender of Roman Catholicism in the face of the Reformation, separated from the Roman Church after failing to secure a divorce from the Pope. His response was to place the King of England as "the only Supreme Head in Earth of the Church of England ", thereby removing the authority of

Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with the six counties that formed Northern Ireland remaining as an autonomous region of the UK. There are two sovereign states in

6300-415: The earliest evidence of human activity on the island of Ireland dates from 12,500 years ago. At the time of the Roman Empire, about two thousand years ago, various tribes, which spoke Celtic dialects of the Insular Celtic group, were inhabiting the islands. The Romans expanded their civilisation to control southern Great Britain but were impeded in advancing any further, building Hadrian's Wall to mark

In front of this line, i.e. in front of

6600-412: The failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland . This title was granted to his younger son, but when Henry's heir unexpectedly died, the title of King of England and Lord of Ireland became entwined in one person. By the Late Middle Ages , Great Britain was separated into

6700-615: The former glaciers, fluviatile and periglacial sediments are widespread. In the Drenthe Stage the present day North Sea basin, Great Britain and Ireland were also affected. Several species were hurt by the glaciation, including the woolly mammoths , which suffered a reduction comparable to the one towards the end of the ice age. The Saale complex may be divided into a lower (also Saale Early Glacial ) and an upper section (also Middle and Upper Saale Glacial, or Younger Saale glaciation ), with glacial advances into Northern Germany. The Saale Early Glacial includes the: The upper part of

6800-545: The global average for the islands' latitudes. Most Atlantic depressions pass to the north of the islands; combined with the general westerly circulation and interactions with the landmass, this imposes a general east–west variation in climate. There are four distinct climate patterns: south-east, with cold winters, warm and dry summers; south-west, having mild and very wet winters, warm and wet summers; north-west, generally wet with mild winters and cool summers; and north-east with cold winters, cool summers. The islands enjoy

7500-664: The most common trees in England. In Scotland, pine and birch are most common. Natural forests in Ireland are mainly oak, ash, wych elm , birch and pine. Beech and lime , though not native to Ireland, are also common there. Farmland hosts a variety of semi-natural vegetation of grasses and flowering plants. Woods, hedgerows , mountain slopes and marshes host heather , wild grasses, gorse and bracken . Many larger animals, such as wolves, bears and European elk are today extinct. However, some species such as red deer are protected. Other small mammals, such as rabbits , foxes , badgers , hares , hedgehogs , and stoats , are very common and

7600-533: The name "Little Britain" for Ireland, though in doing so he is well within the tradition of earlier authors who pair a smaller Ireland with a larger Britain as the two Brettanic Isles". In the second book of Ptolemy's Geography ( c.  150 AD ), the second and third chapters are respectively titled in Greek: Κεφ. βʹ Ἰουερνίας νήσου Βρεττανικῆς θέσις , romanized:  Iouernías nḗsou Brettanikê̄s thésis , lit.   'Ch. 2, position of Hibernia,

7700-464: The norm is by majority rule; however, Northern Ireland uses a system of power sharing whereby unionists and nationalists share executive posts proportionately and where the assent of both groups is required for the Northern Ireland Assembly to make certain decisions. (In the context of Northern Ireland, unionists are those who want Northern Ireland to remain a part of the United Kingdom and nationalists are those who want Northern Ireland to join with

7800-571: The north-western coast of continental Europe , consisting of the islands of Great Britain , Ireland , the Isle of Man , the Inner and Outer Hebrides , the Northern Isles ( Orkney and Shetland ), and over six thousand smaller islands. They have a total area of 315,159 km (121,684 sq mi) and a combined population of almost 72 million, and include two sovereign states ,

7900-464: The northern frontier of their empire in 122 AD. At that time, Ireland was populated by a people known as Hiberni, the northern third or so of Great Britain by a people known as Picts and the southern two thirds by Britons. Anglo-Saxons arrived as Roman power waned in the 5th century AD . Initially, their arrival seems to have been at the invitation of the Britons as mercenaries to repulse incursions by

8000-758: The obligation to join the Schengen Zone. Reciprocal arrangements allow British and Irish citizens specific voting rights in the two states. In Ireland, British citizens can vote in General and local elections, but not in European Parliament elections, constitutional referendums or presidential elections (for which there is no comparable franchise in the United Kingdom). In the United Kingdom, Irish and Commonwealth citizens can vote in every election for which British citizens are eligible. In

8100-565: The phrase Brytish Iles in the Oxford English Dictionary is in a work by John Dee dated 1577. Other names used to describe the islands include the Anglo-Celtic Isles , Atlantic archipelago (a term coined by the historian J. G. A. Pocock in 1975 ), British-Irish Isles , Britain and Ireland , UK and Ireland , and British Isles and Ireland . Owing to political and national associations with

8200-512: The population of the British Isles. The famine caused a century-long population decline, drastically reduced the Irish population and permanently altered the demographic make-up of the British Isles. On a global scale, this disaster led to the creation of an Irish diaspora that numbers fifteen times the current population of the island. The linguistic heritage of the British Isles is rich, with twelve languages from six groups across four branches of

8300-469: The remainder of the archipelago with the exception of the Isle of Man and the Channel Islands. The Isle of Man and the two Bailiwicks of the Channel Islands, Jersey and Guernsey , are known as the Crown Dependencies . They exercise constitutional rights of self-government and judicial independence; responsibility for international representation rests largely with the UK (in consultation with

8400-447: The remnants of Old English (Hiberno-Norman) and Gaelic Irish nobility in Ireland. The new ruling class was Protestant and English, whilst the populace was largely Catholic and Irish. This theme would influence Irish politics for centuries to come. When the monarchy was restored in England, the king found it politically impossible to restore the lands of former landowners in Ireland. The " Glorious Revolution " of 1688 repeated similar themes:

8500-631: The respective governments); and responsibility for defence is reserved by the UK. The United Kingdom is made up of four constituent parts : England, Scotland and Wales, forming Great Britain, and Northern Ireland in the northeast of the island of Ireland. Of these, Scotland, Wales and Northern Ireland have devolved governments, meaning that each has its own parliament or assembly and is self-governing with respect to certain matters set down by law. For judicial purposes, Scotland, Northern Ireland and England and Wales (the latter being one entity) form separate legal jurisdictions, with there being no single law for

8600-585: The rest of Ireland.) The British monarch is the head of state of the United Kingdom, while in the Republic of Ireland the head of state is the President of Ireland . Ireland is the only part of the isles that is a member state of the European Union (EU). The UK was a member between 1 January 1973 and 31 January 2020, but the Isle of Man and the Channel Islands were not. Since the partition of Ireland , an informal free-travel area has existed across

8700-668: The rivers and lakes, in particular salmon, trout, perch and pike . Sea fish include dogfish , cod, sole , pollock and bass, as well as mussels, crab and oysters along the coast. There are more than 21,000 species of insects. Few species of reptiles or amphibians are found in Great Britain or Ireland. Only three snakes are native to Great Britain: the adder , the barred grass snake and the smooth snake ; none are native to Ireland. In general, Great Britain has slightly more variation and native wildlife, with weasels, polecats , wildcats, most shrews , moles , water voles , roe deer and common toads also being absent from Ireland. This pattern

8800-685: The same time as the Wolstonian Stage in the British Isles and the Illinoian Stage in North America . In 1910, the name for "Saale glaciation" was given by German geologists Jacob Stoller and Konrad Keilhack . The maximum advance of the ice sheet in North Germany during the Drenthe Stage is described by a line from Düsseldorf via Paderborn , Hamelin , Goslar , Eisleben , Zeitz and Meissen to Görlitz . From

8900-516: The second-busiest international air route in the world. The English Channel and the southern North Sea are the busiest seaways in the world. The Channel Tunnel , opened in 1994, links Great Britain to France and is the second-longest rail tunnel in the world. The idea of building a tunnel under the Irish Sea has been raised since 1895, when it was first investigated. Several potential Irish Sea tunnel projects have been proposed, most recently

9000-436: The start of the Saale complexes is separated by a warmer period (Dömnitz interglacial) from the actual Saale "ice age". The term "Saale Ice Age" or "Saale Glacial" thus has 2 meanings in the literature – it sometimes refers to the phase in which the glacier advanced into North Germany , but can also refer to the whole Saale complex. The terms are frequently interchanged in the literature. The Saale Glaciation occurred at around

9100-533: The term, and its embassy in London discourages its use. "Britain and Ireland" is used as an alternative description, and "Atlantic Archipelago" has also seen limited use in academia. In official documents created jointly by Ireland and the United Kingdom, such as the Good Friday Agreement , the term "these islands" is used. The earliest known references to the islands as a group appeared in

9200-537: The third highest population behind Great Britain and Ireland. The islands are at relatively low altitudes, with central Ireland and southern Great Britain particularly low-lying: the lowest point in the islands is the North Slob in County Wexford , Ireland, with an elevation of −3.0 metres (−9.8 ft). The Scottish Highlands in the northern part of Great Britain are mountainous, with Ben Nevis being

9300-628: The turn of the first millennium AD, and eventually became a feudal possession of Denmark . The relations between the descendants of Vikings in England and counterparts in Normandy , in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066 . The remnants of the Duchy of Normandy , which conquered England, remain associated to the English Crown as

9400-731: The upper part of the Saale complex is subdivided as follows: The Drenthe Stage corresponds to the maximum extent of glaciation during the Saale complex. During the last stage, the Warthe Stage, glaciers only covered northeast Lower Saxony (parts of the Lüneburg Heath ), the Altmark , the Elbe valley downstream of Magdeburg and the region east of it (c.f. Südlicher Landrücken ), so that these areas are geomorphologically younger than

9500-524: The whole of the islands, for example The X Factor , seasons 3, 4 and 7 of which featured auditions in Dublin and were open to Irish voters, whilst the show previously known as Britain's Next Top Model became Britain and Ireland's Next Top Model in 2011.

9600-426: The word British , the Government of Ireland does not use the term British Isles and in documents drawn up jointly between the British and Irish governments, the archipelago is referred to simply as "these islands". British Isles is the most widely accepted term for the archipelago. The British Isles lie at the juncture of several regions with past episodes of tectonic mountain building. These orogenic belts form

9700-657: The writings of seafarers from the ancient Greek colony of Massalia . The original records have been lost; however, later writings, e.g. Avienius 's Ora maritima , that quoted from the Massaliote Periplus (6th century BC) and from Pytheas 's On the Ocean (around 325–320 BC) have survived. In the 1st century BC, Diodorus Siculus has Prettanikē nēsos , "the British Island", and Prettanoi , "the Britons", describes Julius Caesar as having "advanced

9800-459: Was gradually submerged as sea levels rose. However, the Irish Sea was formed before Doggerland was completely covered in water, with Ireland becoming an island roughly 6,000 years before Great Britain did. The first evidence of human activity on the islands dates from 840,000 or 950,000 years ago, based in flint tools found near Happisburgh on the Norfolk coast of Great Britain. In contrast,

9900-614: Was named after the site of Wolston in the English county of Warwickshire where corresponding deposits were first identified. Acheulian flint tools have been found in Wolstonian deposits. Warthe Stage The Saale glaciation or Saale Glaciation , sometimes referred to as the Saalian glaciation , Saale cold period ( German : Saale-Kaltzeit ), Saale complex ( Saale-Komplex ) or Saale glacial stage (called

10000-523: Was not inhabited until after 8000 BC. Great Britain became an island by 7000 BC with the flooding of Doggerland . The Gaels (Ireland), Picts (northern Great Britain) and Britons (southern Great Britain), all speaking Insular Celtic languages , inhabited the islands at the beginning of the 1st millennium BC. Much of Brittonic-occupied Britain was conquered by the Roman Empire from AD 43. The first Anglo-Saxons arrived as Roman power waned in
