England (pronounced IPA: /ˈɪŋglənd/) (Old English: Englaland, Middle English: Engelond) is the largest and most populous constituent country of the United Kingdom of Great Britain and Northern Ireland. Its inhabitants account for more than 83% of the total population of the United Kingdom, whilst the mainland territory of England occupies most of the southern two-thirds of the island of Great Britain and shares land borders with Scotland to the north and Wales to the west. Elsewhere, it is bordered by the North Sea, Irish Sea, Atlantic Ocean, and English Channel.
England became a unified state during the 10th century and takes its name from the Angles, one of a number of Germanic tribes who settled in the territory during the 5th and 6th centuries. The capital city of England is London, which is the largest city in Great Britain, and the largest city in the European Union by most, but not all, measures.
England ranks amongst the world's most influential and far-reaching centres of cultural development. It is the place of origin of both the English language and the Church of England, and English law forms the basis of the legal systems of many countries: in addition, London, the country's capital, was the centre of the British Empire, and the country was also the birthplace of the Industrial Revolution. England was the first country in the world to become industrialised. England is home to the Royal Society, which laid the foundations of modern experimental science. England was the world's first parliamentary democracy and consequently many constitutional, governmental and legal innovations that had their origin in England have been widely adopted by other nations.
The Kingdom of England was a separate state until 1 May 1707, when the Acts of Union resulted in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. With the Principality of Wales already in the English state. Great Britain is the term in use for the largest island in the British Isles, with the name's origins in the Celtic 'People of the Islands', or Pretani.

Sheffield is a large city and metropolitan borough in South Yorkshire, England. It is so named because of its origins in a field on the River Sheaf that runs through the city.
The city has grown from its largely industrial roots to encompass a wide economic base. The population of the City of Sheffield is estimated at 520,700 people (2005), and it is one of the eight largest English cities outside London, which form the English Core Cities Group. The wider Sheffield Urban Area, which extends beyond the city proper, has a population of 640,720.
Historically part of the West Riding of Yorkshire, Sheffield obtained world-wide recognition during the 19th century for its production of steel. Many innovations in the industry were developed locally, including crucible and stainless steel. This fuelled an almost tenfold increase in the population during the Industrial Revolution. It gained its city charter in 1893 and became officially titled the City of Sheffield. International competition caused a decline in local industry during the 1970s and 1980s, and at the same time the nearby national coal industry collapsed, affecting Sheffield's population.
Sheffield is located at . It lies directly beside Rotherham, from which it is separated by the M1 motorway. Although Barnsley Metropolitan Borough also borders Sheffield to the north, the town itself is a few miles further away. The southern and western borders of the city are shared with Derbyshire; in the first half of the 20th century Sheffield extended its borders south into Derbyshire, annexing a number of villages, including Totley, Dore and the area now known as Mosborough Townships. Directly to the west of the city is the Peak District National Park and the Pennine hill range.
Sheffield is a geographically diverse city. The city nestles in a natural amphitheatre created by several hills[17] and the confluence of five rivers: Don, Sheaf, Rivelin, Loxley and Porter. As such, much of the city is built on hillsides with views into the city centre or out to the countryside. The city's lowest point is just 10 metres (33 ft) above sea level, while some parts of the city are at over 500 metres (1,640 ft). However, 89% of the housing in the city is between 100 and 200 metres (330 & 660 ft) above sea level.
With an estimated total of over two million trees, Sheffield has more trees per person than any other city in Europe. It has over 170 woodlands (covering 28.27 km² / 10.9 mi²), 78 public parks (covering 18.30 km² / 7.1 mi²) and 10 public gardens. Added to the 134.66 km² (52 mi²) of national park and 10.87 km² (4.2 mi²) of water this means that 61% of the city is greenspace.
Sheffield also has a very wide variety of habitat, comparing favourably with any city in the United Kingdom: urban, parkland and woodland, agricultural and arable land, moors, meadows and freshwater-based habitats. Large parts of the city are designated as sites of special scientific interest including several urban areas.
The present city boundaries were set in 1974 (with slight modification in 1994), when the former county borough of Sheffield merged with Stocksbridge Urban District and two parishes from the Wortley Rural District. This area includes a significant part of the countryside surrounding the main urban region. Roughly a third of Sheffield lies in the Peak District National Park (no other English city includes parts of a national park within its boundary), and Sheffield often boasts of being Europe's greenest city, a claim that was reinforced when it won the 2005 Entente Florale competition. This was helped by the fact that Sheffield contains over 150 woodland spaces and 50 public parks.
