Berkshire (/ˈbɑːrkʃər/ or /ˈbɑːrkʃɪər/, abbreviated Berks) is a county of south east England, located to the west of London. It has also been known as the Royal County of Berkshire since at least the 19th century because of the presence of Windsor Castle and was recognised as such by the Queen in 1957 and letters patent issued in 1974. Berkshire is a county of historic origin and is both a ceremonial county and a non-metropolitan county without a county council. Berkshire County Council was the main county governance from 1889 to 1998 except for the separately administered County Borough of Reading.
In 1974, significant alterations were made to the county's administrative boundaries although the traditional boundaries of Berkshire were not changed. The towns of Abingdon, Didcot and Wantage were transferred to Oxfordshire, Slough was gained from Buckinghamshire and the separate administration of Reading was ended. Since 1998, Berkshire has been governed by the six unitary authorities of Bracknell Forest, Reading, Slough, West Berkshire, Windsor and Maidenhead and Wokingham. It borders the counties of Oxfordshire (to the north), Buckinghamshire (to the north-east), Greater London (to the east), Surrey (to the south-east), Wiltshire (to the west) and Hampshire (to the south).
England i/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 northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers much of the central and southern part of the island of Great Britain, which lies in the North Atlantic; and 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 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 the 10th century, 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.
