Sheffield

Sheffield is a city in South Yorkshire, England, situated 29 miles (47 km) south of Leeds and 32 miles (51 km) east of Manchester. The city is the administrative centre of the City of Sheffield. It is historically part of the West Riding of Yorkshire. It is the largest settlement in South Yorkshire and the third largest of Northern England.

The city is in the eastern foothills of the Pennines and the valleys of the River Don with 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 and is the fifth-largest city in England. 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, developing many significant technologies. In the 19th century, the city saw a huge expansion of its traditional cutlery trade, when processes for high-quality stainless steel and crucible steel were invented. This fuelled 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 Yorkshire ridings became counties in their own right in 1889; the West Riding of Yorkshire county was disbanded in 1974. The city then became part of the county of South Yorkshire; this has been made up of separately governed unitary authorities since 1986. The 21st century has seen extensive redevelopment in Sheffield, consistent with other British cities. Sheffield's gross value added (GVA) has increased by 60% since 1997, standing at £11.3 billion in 2015. The economy has experienced steady growth, averaging around 5% annually, which is greater than that of the broader region of Yorkshire and the Humber.

Sheffield had a population of 556,500 at the 2021 census, making it the second-largest city in the Yorkshire and the Humber region. The Sheffield Built-up Area, of which the Sheffield sub-division is the largest part, had a population of 685,369 also including the town of Rotherham. The district borough, governed from the city, had a population of 582,493 at the mid-2019 estimate, making it the 7th-most-populous district in England. It is one of eleven British cities that make up the Core Cities Group. In 2011, the unparished area had a population of 490,070.

The city has a long sporting heritage and is home both to the world's oldest football club, Sheffield F.C., and the world's oldest football ground, Sandygate. Matches 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.

Sheffield takes its name from the River Sheaf, which runs through the city centre (albeit in underground culverts). The river's name comes from the Old English word scēað, meaning "boundary", possibly because the Sheaf once formed part of the boundary between the kingdoms of Mercia and Northumbria. The second element is Old English feld, meaning "open countryside", and the name thus means "open countryside near the River Sheaf". It first appears in the Domesday Book.

The area now occupied by the City of Sheffield is believed to have been inhabited since at least the late Upper Paleolithic, about 12,800 years ago. The earliest evidence of human occupation in the Sheffield area was found at Creswell Crags to the east of the city. In the Iron Age the area became the southernmost territory of the Pennine tribe called the Brigantes. It is this tribe who are thought to have constructed several hillforts in and around Sheffield.

Following the departure of the Romans, the Sheffield area may have been the southern part of the Brittonic kingdom of Elmet, with the rivers Sheaf and Don forming part of the boundary between this kingdom and the kingdom of Mercia. Gradually, Anglian settlers pushed west from the kingdom of Deira. A Britonnic presence within the Sheffield area is evidenced by two settlements called Wales and Waleswood close to Sheffield. The settlements that grew and merged to form Sheffield, however, date from the second half of the first millennium, and are of Anglo-Saxon and Danish origin. In Anglo-Saxon times, the Sheffield area straddled the border between the kingdoms of Mercia and Northumbria. The Anglo-Saxon Chronicle reports that Eanred of Northumbria submitted to Egbert of Wessex at the hamlet of Dore (now a suburb of Sheffield) in 829, a key event in the unification of the kingdom of England under the House of Wessex.
