England (ˈɪŋɡlənd) is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies north west of England, whilst the Celtic Sea lies to the south west. The North Sea to the east and the English Channel to the south separate it from continental Europe. Most of England comprises the central and southern part of the island of Great Britain in the North Atlantic. The country also includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.

The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but it takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in 927 AD, and since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world. The English language, the Anglican Church, and English law - the basis for the common law legal systems of many other countries around the world - developed in England, and the country's parliamentary system of government has been widely adopted by other nations. The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation.

England's terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north (for example, the mountainous Lake District, Pennines, and Yorkshire Dales) and in the south west (for example, Dartmoor and the Cotswolds). The former capital of England was Winchester until replaced by London in 1066. Today London is the largest metropolitan area in the United Kingdom and the largest urban zone in the European Union by most measures. England's population is about 53 million, around 84% of the population of the United Kingdom, and is largely concentrated in London, the South East and conurbations in the Midlands, the North West, the North East and Yorkshire, which each developed as major industrial regions during the 19th century. Meadowlands and pastures are found beyond the major cities.

The Kingdom of England - which after 1284 included Wales - was a sovereign state until 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the new Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922, the Irish Free State was established as a separate dominion, but the Royal and Parliamentary Titles Act 1927 reincorporated into the kingdom six Irish counties to officially create the current United Kingdom of Great Britain and Northern Ireland.

Toponymy

The name "England" is derived from the Old English name Englaland, which means "land of the Angles". The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. According to the Oxford English Dictionary, the first known use of "England" to refer to the southern part of the island of Great Britain occurs in 897, and its modern spelling was first used in 1538.

The earliest attested mention of the name occurs in the 1st century work by Tacitus, Germania, in which the Latin word Anglii is used. The etymology of the tribal name itself is disputed by scholars; it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. How and why a term derived from the name of a tribe that was less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England (Sasunn), and the Welsh use "Saesneg" - a form derived from "Saxon" - to describe the English language.

An alternative name for England is Albion. The name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth. In it are two very large islands called Britannia; these are Albion and Ierne". But modern scholar consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. to later a later Graeco-Roman period. The word Albion (Ἀλβίων) or insula Albionum has two possible origins. It either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover, the only part of Britain visible from the European Continent, or from the phrase the "island of the Albiones in the now lost Massaliote Periplus, that is attested through Avienus' Ora Maritima to which the former presumably served as a source.Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, and made popular by its use in Arthurian legend.
