Sheffield is a city and metropolitan borough in South Yorkshire, England. Historically part of the West Riding of Yorkshire, its name derives from the River Sheaf, which runs through the city. With some of its southern suburbs annexed from Derbyshire, the city has grown from its largely industrial roots to encompass a wider economic base. The population of the City of Sheffield is 582,506 (mid-2018 est.) and it is one of the eight largest regional English cities that make up the Core Cities Group. Sheffield is the third-largest English district by population. The metropolitan population of Sheffield is 1,569,000.The city is in the eastern foothills of the Pennines, and the valleys of the River Don and its four tributaries, the Loxley, the Porter Brook, the Rivelin and the Sheaf. Sixty-one per cent of Sheffield's entire area is green space, and a third of the city lies within the Peak District national park. There are more than 250 parks, woodlands and gardens in the city, which is estimated to contain around 4.5 million trees.Sheffield played a crucial role in the Industrial Revolution, with many significant inventions and technologies developed in the city. In the 19th century, the city saw a huge expansion of its traditional cutlery trade, when stainless steel and crucible steel were developed locally, fuelling an almost tenfold increase in the population. Sheffield received its municipal charter in 1843, becoming the City of Sheffield in 1893. International competition in iron and steel caused a decline in these industries in the 1970s and 1980s, coinciding with the collapse of coal mining in the area. The 21st century has seen extensive redevelopment in Sheffield, along with other British cities. Sheffield's gross value added (GVA) has increased by 60% since 1997, standing at £9.2 billion in 2007. The economy has experienced steady growth averaging around 5% annually, greater than that of the broader region of Yorkshire and the Humber.The city has a long sporting heritage, and is home to the world's oldest football club, Sheffield F.C. Games between the two professional clubs, Sheffield United and Sheffield Wednesday, are known as the Steel City derby. The city is also home to the World Snooker Championship and the Sheffield Steelers, the UK's first professional ice hockey team.

Manchester () is a major city and metropolitan borough in Greater Manchester, England, with a population of 545,500 as of 2017 (5th most populous English district). It lies within the United Kingdom's second-most populous urban area, with a population of 2.7 million, and third-most populous metropolitan area, with a population of 3.3 million. It is fringed by the Cheshire Plain to the south, the Pennines to the north and east, and an arc of towns with which it forms a continuous conurbation. The local authority for the city is Manchester City Council. The recorded history of Manchester began with the civilian settlement associated with the Roman fort of Mamucium or Mancunium, which was established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. It is historically a part of Lancashire, although areas of Cheshire south of the River Mersey were incorporated in the 20th century. The first to be included, Wythenshawe, was added to the city in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchester's unplanned urbanisation was brought on by a boom in textile manufacture during the Industrial Revolution, and resulted in it becoming the world's first industrialised city. Manchester achieved city status in 1853. The Manchester Ship Canal opened in 1894, creating the Port of Manchester and directly linking the city to the Irish Sea, 36 miles (58 km) to the west. Its fortune declined after the Second World War, owing to deindustrialisation, but the IRA bombing in 1996 led to extensive investment and regeneration. Following successful redevelopment after the IRA bombing, Manchester was the host city for the 2002 Commonwealth Games. Manchester is the third most visited city in the UK, after London and Edinburgh. It is notable for its architecture, culture, musical exports, media links, scientific and engineering output, social impact, sports clubs and transport connections. A city of notable firsts, Manchester Liverpool Road railway station was the world's first inter-city passenger railway station. The city has also excelled in scientific advancement, as it was at The University of Manchester in 1917 that scientist Ernest Rutherford first split the atom, in 1948 Frederic C. Williams, Tom Kilburn, and Geoff Tootill developed and built the world's first stored-program computer, and in 2004 Andre Geim and Konstantin Novoselov successfully isolated and characterised the first graphene.
