Great Britain is an island in the North Atlantic Ocean off the north-west coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island, and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The island of Ireland, with an area 40 per cent that of Great Britain, is to the west. These islands, along with over 1,000 smaller surrounding islands and named substantial rocks, comprise the British Isles archipelago.

The term "Great Britain" can also refer to the political territory of England, Scotland and Wales, which includes their offshore islands. This territory, together with Northern Ireland, constitutes the United Kingdom.

Connected to mainland Europe until 9,000 years ago by a land bridge now known as Doggerland, the island of Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Honshu in Japan and Java in Indonesia,See Geohive.com Country data ; Japan Census of 2000; United Kingdom Census of 2001. The editors of List of islands by population appear to have used similar data from the relevant statistics bureaux and totalled up the various administrative districts that make up each island, and then done the same for less populous islands.

Terminology

Toponymy

The archipelago has been referred to by a single name for over 2000 years: the term 'British Isles' derives from terms used by classical geographers to describe this island group. By 50 BC, Greek geographers were using equivalents of Prettanikē as a collective name for the British Isles. However, with the Roman conquest of Britain, the Latin term was used for the island of Great Britain, and later Roman-occupied Britain south of Caledonia.4.20 provides a translation describing Caesar's first invasion, using terms which from IV.XX appear in Latin as arriving in "Britannia", the inhabitants being "Britanni", and on p30 "principes Britanniae" (i.e., "chiefs of Britannia") is translated as "chiefs of Britain".

The earliest known name for Great Britain is Albion () or insula Albionum, from either the Latin meaning "white" (possibly referring to the white cliffs of Dover, the first view of Britain from the continent) or the "island of the Albiones". The oldest mention of terms related to Great Britain was by Aristotle (384–322 BC), or possibly by Pseudo-Aristotle, in his text On the Universe, Vol. III. To quote his works, "There are two very large islands in it, called the British Isles, Albion and Ierne"."... ἐν τούτῳ γε μὴν νῆσοι μέγιστοι τυγχάνουσιν οὖσαι δύο, Βρεττανικαὶ λεγόμεναι, Ἀλβίων καὶ Ἰέρνη, ...", transliteration "... en toutôi ge mên nêsoi megistoi tynchanousin ousai dyo, Brettanikai legomenai, Albiôn kai Iernê, ...", Aristotle: On Sophistical Refutations. On Coming-to-be and Passing Away. On the Cosmos., 393b, pages 360–361, Loeb Classical Library No. 400, London William Heinemann LTD, Cambridge, Massachusetts University Press MCMLV

The first known written use of the word Britain was an ancient Greek transliteration of the original Proto-Celtic term in a work on the travels and discoveries of Pytheas that has not survived. The earliest existing records of the word are quotations of the periplus by later authors, such as those within Strabo's Geographica, Pliny's Natural History and Diodorus of Sicily's .Book I.4.2–4, Book II.3.5, Book III.2.11 and 4.4, Book IV.2.1, Book IV.4.1, Book IV.5.5, Book VII.3.1 Pliny the Elder (AD 23–79) in his Natural History records of Great Britain: "Its former name was Albion; but at a later period, all the islands, of which we shall just now briefly make mention, were included under the name of 'Britanniæ.Pliny the Elder's Naturalis Historia Book IV. Chapter XLI Latin text and English translation, numbered Book 4, Chapter 30, at the Perseus Project.

The name Britain descends from the Latin name for Britain, or , the land of the Britons. Old French (whence also Modern French ) and Middle English , . The French form replaced the Old English (also ). Britannia was used by the Romans from the 1st century BC for the British Isles taken together. It is derived from the travel writings of Pytheas around 320 BC, which described various islands in the North Atlantic as far north as Thule (probably Norway).

The peoples of these islands of Prettanike were called the Πρεττανοί, Priteni or Pretani. Priteni is the source of the Welsh language term , Britain, which has the same source as the Goidelic term Cruithne used to refer to the early Brythonic-speaking inhabitants of the Scottish highlands and the north of Scotland. The latter were later called Picts or Caledonians by the Romans. Greek historians Diodorus of Sicily and Strabo preserved variants of Prettanike from the work of Greek explorer Pytheas of Massalia, who travelled from his home in Hellenistic southern Gaul to Britain in the 4th century BC. The term used by Pytheas may derive from a Celtic word meaning "the painted ones" or "the tattooed folk" in reference to body decorations.Cunliffe, Barry (2012). Britain Begins. Oxford, UK: Oxford University Press. p. 4, . According to Strabo, Pytheas referred to Britain as Bretannikē, which is treated a feminine noun.Strabo's Geography Book I. Chapter IV. Section 2 Greek text and English translation at the Perseus Project.Strabo's Geography Book IV. Chapter II. Section 1 Greek text and English translation at the Perseus Project.Strabo's Geography Book IV. Chapter IV. Section 1 Greek text and English translation at the Perseus Project. Marcian of Heraclea, in his Periplus maris exteri, described the island group as (the Prettanic Isles). Greek text and Latin Translation thereof archived at the Internet Archive.

Derivation of Great

The Greco-Egyptian scientist 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). In his later work, Geography (), he gave the islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been the names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Britain, after which Britain became the more commonplace name for the island.

After the Anglo-Saxon period, Britain was used as a historical term only. Geoffrey of Monmouth in his pseudohistorical () refers to the island of Great Britain as Britannia major ("Greater Britain"), to distinguish it from Britannia minor ("Lesser Britain"), the continental region which approximates to modern Brittany and had been settled in the fifth and sixth centuries by Celtic Briton migrants from Great Britain.

The term Great Britain was first used officially in 1474, in the instrument drawing up the proposal for a marriage between Cecily, daughter of Edward IV of England, and James, son of James III of Scotland, which described it as "this Nobill Isle, callit Gret Britanee". The Scottish philosopher and historian, John Major (Mair), published his 'History of Great Britain, both England and Scotland' (Historia majoris Britanniae, tam Angliae quam Scotiae) in 1521. While promoting a possible royal match in 1548, Lord Protector Somerset said that the English and Scots were, "like as twoo brethren of one Islande of great Britaynes again." In 1604, James VI and I styled himself "King of Great Brittaine, France and Ireland".Nicholls, Andrew D., The Jacobean Union: A Reconsideration of British Civil Policies Under the Early Stuarts, 1999. p. 5.

Modern use of the term Great Britain Great Britain refers geographically to the island of Great Britain. Politically, it may refer to the whole of England, Scotland and Wales, including their smaller offshore islands. It is not technically correct to use the term to refer to the whole of the United Kingdom which includes Northern Ireland, though the Oxford English Dictionary states "...the term is also used loosely to refer to the United Kingdom."

Similarly, Britain can refer to the island of Great Britain, to the island of Great Britain together with the other islands of England, Scotland, and Wales, or to the United Kingdom as a whole. There is no clear distinction, even in government documents: the UK government yearbooks have used both Britain and United Kingdom.

GB and GBR are used instead of UK in some international codes to refer to the United Kingdom, including the Universal Postal Union, international sports teams, NATO, and the International Organization for Standardization country codes ISO 3166-2 and ISO 3166-1 alpha-3, whilst the aircraft registration prefix is G.

On the Internet, .uk is the country code top-level domain for the United Kingdom. A .gb top-level domain was used to a limited extent, but is now deprecated. Although existing registrations still exist (mainly by government organisations and email providers), this domain name registrar will not take new registrations.

In the Olympics, Team GB is used by the British Olympic Association to represent the British Olympic team. The Olympic Federation of Ireland represents the whole island of Ireland, and Northern Irish sportspeople may choose to compete for either team,HL Deb 21 October 2004 vol 665 c99WA Hansard most choosing to represent Ireland.

Political definition

Politically, Great Britain refers to the whole of England, Scotland and Wales in combination, but not Northern Ireland; it includes islands, such as the Isle of Wight, Anglesey, the Isles of Scilly, the Hebrides and the island groups of Orkney and Shetland, that are part of England, Wales, or Scotland. It does not include the Isle of Man and the Channel Islands.

The political union which joined the kingdoms of England and Scotland occurred in 1707 when the Acts of Union ratified the 1706 Treaty of Union and merged the parliaments of the two nations, forming the Kingdom of Great Britain, which covered the entire island. Before this, a personal union had existed between these two countries since the 1603 Union of the Crowns when James VI of Scotland inherited the English throne whilst reigning as King of Scotland. Thereafter, he became James I of England, whilst still reigning as James VI in Scotland.

History Prehistoric period

The oldest evidence for archaic humans in Britain are the Happisburgh footprints and associated stone tools found in Norfolk, dating to around 950–850,000 years ago. Prior to 450,000 years ago, Britain formed a peninsular extension of mainland Europe until catastrophic flooding between then and 130,000 years ago resulted in the creation of the English Channel and Britain becoming an island during warm interglacial periods like the Last Interglacial/Eemian (130–115,000 years ago), though it remained connected to mainland Europe during glacial periods when sea levels were low. Archaic humans repeatedly occupied Britain before abandoning the area during cooler periods. Modern humans arrived in Britain about 40,000 years ago, as evidenced by remains found in Kents Cavern in Devon, following the disappearance of Neanderthals. Prior to 9,000 years ago Britain retained a land connection to the continent, with an area of mostly low marshland (Doggerland) joining it to what are now Denmark and the Netherlands.Edwards, Robin & al.
