Staffordshire (; postal abbreviation Staffs.) is a landlocked ceremonial and historic county in the West Midlands of England. It borders Cheshire to the north-west, Derbyshire and Leicestershire to the east, Warwickshire to the south-east, the West Midlands county and Worcestershire to the south, and Shropshire to the west. The largest settlement is the city of Stoke-on-Trent; the county town is Stafford.
The county has an area of 1,713 square kilometres (661 sq mi) and a population of 1,131,052. After Stoke-on-Trent (258,366), the largest settlements are Tamworth (78,646), Newcastle-under-Lyme (75,082) and Burton upon Trent (72,299); the city of Lichfield has a population of 33,816. For local government purposes Staffordshire comprises a non-metropolitan county, with nine districts, and the unitary authority area of Stoke-on-Trent. The county historically included the north-west of the West Midlands county, including Walsall, West Bromwich, and Wolverhampton.
Staffordshire is hilly to the north and south. The southern end of the Pennines is in the north, containing part of the Peak District National Park, while the Cannock Chase AONB and part of the National Forest are in the south. The River Trent and its tributaries drain most of the county. The river has its source near Biddulph and flows through Staffordshire in a southwesterly direction, meeting the Sow just east of Stafford before turning north-east at its confluence with the River Tame and exiting into Derbyshire immediately after Burton-upon-Trent.
Staffordshire contains a number of Iron Age tumuli and Roman camps, and was settled by the Angles in the sixth century; the oldest Stafford knot, the county's symbol, can be seen on an Anglian cross in the churchyard of Stoke Minster. The county was formed in the early tenth century, when Stafford became the capital of Mercia. The county was relatively settled in the following centuries, and rapidly industrialised during the Industrial Revolution, when the North Staffordshire coalfield was exploited and fuelled the iron and automobilie industries in the south of the county. Pottery is the county's most famous export; a limited amount is still produced in Stoke-on-Trent.
