Dorset

Dorset (/ˈdɔːrsɪt/ DOR-sit; archaically: Dorsetshire /ˈdɔːrsɪt.ʃɪər, -ʃər/ DOR-sit-sheer, -⁠shər) is a ceremonial county in South West England. It is bordered by Somerset to the north-west, Wiltshire to the north and the north-east, Hampshire to the east, the Isle of Wight across the Solent to the south-east, the English Channel to the south, and Devon to the west. The largest settlement is Bournemouth, and the county town is Dorchester.

The county has an area of 2,653 km² (1,024 sq mi) and a population of 772,268. Around half of the population lives in the South East Dorset conurbation, which contains three of the county's largest settlements: Bournemouth (183,491), Poole (151,500), and Christchurch (31,372). The remainder of the county is largely rural, and its principal towns are Weymouth (53,427) and Dorchester (21,366). Dorset contains two unitary districts: Bournemouth, Christchurch and Poole (BCP) and Dorset. The county did not historically include Bournemouth and Christchurch, which were part of Hampshire.

Dorset has a varied landscape of chalk downs, steep limestone ridges, and low-lying clay valleys. The majority of its coastline is part of the Jurassic Coast World Heritage Site due to its geological and palaeontologic significance, and features notable landforms such as Lulworth Cove, the Isle of Portland, Chesil Beach and Durdle Door. The north of the county contains part of Cranborne Chase, a chalk downland. The highest point in Dorset is Lewesdon Hill (279 m (915 ft)), in the southwest.

There is evidence of Neolithic, Celtic, and Roman settlement in Dorset, and during the Early Middle Ages the region was settled by the Saxons; the county developed in the 7th century. The first recorded Viking raid on the British Isles occurred in Dorset in 789 AD, and the Black Death entered England at Melcombe Regis in 1348. The county has seen much civil unrest: in the English Civil War an uprising of Clubmen vigilantes was crushed by Oliver Cromwell's forces in a pitched battle near Shaftesbury; the doomed Monmouth Rebellion began at Lyme Regis; and the Tolpuddle Martyrs, a group of Dorset farm labourers, were instrumental in the formation of the trade union movement. During the Second World War, Dorset was heavily involved in the preparations for the invasion of Normandy, and the large harbours of Portland and Poole were two of the main embarkation points. Agriculture was historically the major industry of Dorset, but is now in decline in favour of tourism.

Dorset derives its name from the county town of Dorchester. The Romans established the settlement in the 1st century and named it Durnovaria which was a Latinised version of a Common Brittonic word possibly meaning "place with fist-sized pebbles". The Saxons named the town Dornwaraceaster (the suffix -ceaster being the Old English name for a "Roman town"; cf. Exeter and Gloucester) and Dornsæte came into use as the name for the inhabitants of the area from Dorn (a reduced form of Dornwaraceaster) and the Old English word sæte (meaning "people"). The same ending can also be seen in the neighbouring Somerset. It is first mentioned in the Anglo-Saxon Chronicle in AD 845 and in the 10th century the county's archaic name, Dorseteschyre (Dorsetshire), was first recorded.

The first human visitors to Dorset were Mesolithic hunters, from around 8000 BC. The first permanent Neolithic settlers appeared around 3000 BC and were responsible for the creation of the Dorset Cursus, a 10.5-kilometre (6.5 mi) monument for ritual or ceremonial purposes. From 2800 BC onwards Bronze Age farmers cleared Dorset's woodlands for agricultural use and Dorset's high chalk hills provided a location for numerous round barrows. During the Iron Age, the British tribe known as the Durotriges established a series of hill forts across the county—most notably Maiden Castle which is one of the largest in Europe.

The Romans arrived in Dorset during their conquest of Britain in AD 43. Maiden Castle was captured by the Legio II Augusta under the command of Vespasian, and the Roman settlement of Durnovaria was established nearby. Bokerley Dyke, a large defensive ditch built by the county's post-Roman inhabitants near the border with modern-day Hampshire, delayed the advance of the Saxons into Dorset for almost 150 years. It appears to have been re-fortified during this period, with the former Roman Road at Ackling Dyke also being blocked by the Britons, apparently to prevent the West Saxon advance into Dorset.

However, by the end of the 7th century Dorset had fallen under Saxon control and been incorporated into the Kingdom of Wessex. The precise details of this West Saxon conquest and how it took place are not clear, but it appears to have substantially taken place by the start of the reign of Caedwalla in 685. The Saxons established a diocese at Sherborne (later to develop into the Diocese of Salisbury) and Dorset was made a shire—an administrative district of Wessex and predecessor to the English county system—with borders that have changed little since. In 789 the first recorded Viking attack on the British Isles took place in Dorset on the Portland coast, and they continued to raid into the county for the next two centuries.
