Bristol is a city and ceremonial county in England. With a population of 463,400, it is the most populous city in South West England. The wider Bristol Built-Up Area has the 10th-largest population in England. The urban area population of 670,000 is the 11th-largest in the United Kingdom. The city lies between Gloucestershire to the north and Somerset to the south. South Wales lies across the Severn estuary.

History

Archaeological finds, including flint tools believed to be between 300,000 and 126,000 years old made with the Levallois technique, indicate the presence of Neanderthals in the Shirehampton and St Annes areas of Bristol during the Middle Palaeolithic. Iron Age hill forts near the city are at Leigh Woods and Clifton Down, on the side of the Avon Gorge, and on Kings Weston Hill near Henbury. A Roman settlement, Abona, existed at what is now Sea Mills (connected to Bath by a Roman road); another was at the present-day Inns Court. Isolated Roman villas and small forts and settlements were also scattered throughout the area.

Middle Ages

Bristol was founded by 1000; by about 1020, it was a trading centre with a mint producing silver pennies bearing its name. By 1067 Brycgstow was a well-fortified burh, and that year the townsmen beat back a raiding party from Ireland led by three of Harold Godwinson's sons. Under Norman rule, the town had one of the strongest castles in southern England. Bristol was the place of exile for Diarmait Mac Murchada, the Irish king of Leinster, after being overthrown. The Bristol merchants subsequently played a prominent role in funding Richard Strongbow de Clare and the Norman invasion of Ireland.

The port developed in the 11th century around the confluence of the Rivers Frome and Avon, adjacent to Bristol Bridge just outside the town walls. By the 12th century Bristol was an important port, handling much of England's trade with Ireland, including slaves. There was also an important Jewish community in Bristol from the late 12th century through to the late 13th century when all Jews were expelled from England. The stone bridge built in 1247 was replaced by the current bridge during the 1760s. The town incorporated neighbouring suburbs and became a county in 1373, the first town in England to be given this status. During this period, Bristol became a shipbuilding and manufacturing centre. By the 14th century Bristol, York and Norwich were England's largest medieval towns after London. One-third to one-half of the population died in the Black Death of 1348–49, which checked population growth, and its population remained between 10,000 and 12,000 for most of the 15th and 16th centuries.

15th and 16th centuries

During the 15th century Bristol was the second most important port in the country, trading with Ireland, Iceland and Gascony. It was the starting point for many voyages, including Robert Sturmy's (1457–58) unsuccessful attempt to break the Italian monopoly of Eastern Mediterranean trade. New exploration voyages were launched by Venetian John Cabot, who in 1497 made landfall in North America. A 1499 voyage, led by merchant William Weston of Bristol, was the first expedition commanded by an Englishman to North America. During the first decade of the 16th century Bristol's merchants undertook a series of exploration voyages to North America and even founded a commercial organisation, 'The Company Adventurers to the New Found Land', to assist their endeavours. However, they seem to have lost interest in North America after 1509, having incurred great expenses and made little profit.

During the 16th century, Bristol merchants concentrated on developing trade with Spain and its American colonies. This included the smuggling of prohibited goods, such as food and guns, to Iberia during the Anglo-Spanish War (1585–1604). Bristol's illicit trade grew enormously after 1558, becoming integral to its economy.

The original Diocese of Bristol was founded in 1542, when the former Abbey of St. Augustine (founded by Robert Fitzharding four hundred years earlier) became Bristol Cathedral. Bristol also gained city status that year. During the English Civil War in the 1640s the city was occupied by Royalists, who built the Royal Fort House on the site of an earlier Parliamentarian stronghold.

17th and 18th centuries

Fishermen from Bristol, who had fished the Grand Banks of Newfoundland since the 16th century, began settling Newfoundland permanently in larger numbers during the 17th century, establishing colonies at Bristol's Hope and Cuper's Cove. Growth of the city and trade came with the rise of England's American colonies in the 17th century. Bristol's location on the west side of Great Britain gave its ships an advantage in sailing to and from the New World, and the city's merchants made the most of it. Bristol was a major supplier of slaves to South Carolina before 1750.

The 18th century saw an expansion of Bristol's role in the Atlantic trade in Africans taken for slavery to the Americas. Bristol and later Liverpool became centres of the Triangular Trade. Manufactured goods were shipped to West Africa and exchanged for Africans; the enslaved captives were transported across the Atlantic to the Americas in the Middle Passage under brutal conditions. Plantation goods such as sugar, tobacco, rum, rice, cotton and a few slaves (sold to the aristocracy as house servants) returned across the Atlantic to England. Some household slaves were baptised in the hope this would lead them to be freed. The Somersett Case of 1772 clarified that slavery was illegal in England. At the height of the Bristol slave trade from 1700 to 1807, more than 2,000 slave ships carried a conservatively estimated 500,000 people from Africa to slavery in the Americas.

In 1739 John Wesley founded the first Methodist chapel, the New Room, in Bristol. Wesley, along with his brother Charles Wesley and George Whitefield, preached to large congregations in Bristol and the neighbouring village of Kingswood, often in the open air.

Wesley published a pamphlet on slavery, titled Thoughts Upon Slavery, in 1774 and the Society of Friends began lobbying against slavery in Bristol in 1783. The city's scions remained nonetheless strongly anti-abolitionist. Thomas Clarkson came to Bristol to study the slave trade and gained access to the Society of Merchant Venturers records. One of his contacts was the owner of the Seven Stars public house, who boarded sailors Clarkson sought to meet. Through these sailors he was able to observe how slaver captains and first mates "plied and stupefied seamen with drink" to sign them up. Other informants included ship surgeons and seamen seeking redress. When William Wilberforce began his parliamentary abolition campaign on 12 May 1788, he recalled the history of the Irish slave trade from Bristol, which he provocatively claimed continued into the reign of Henry VII. Hannah More, originally from Bristol, and a good friend of both Wilberforce and Clarkson, published "Slavery, A Poem" in 1788, just as Wilberforce began his parliamentary campaign. His major speech on 2 April 1792 likewise described the Bristol slave trade specifically, and led to the arrest, trial and subsequent acquittal of a local slaver captain named Kimber.

19th century

The city was associated with Victorian engineer Isambard Kingdom Brunel, who designed the Great Western Railway between Bristol and London Paddington, two pioneering Bristol-built oceangoing steamships (SS Great Britain and SS Great Western), and the Clifton Suspension Bridge. The new railway replaced the Kennet and Avon Canal, which had fully opened in 1810 as the main route for the transport of goods between Bristol and London. Competition from Liverpool (beginning around 1760), disruptions of maritime commerce due to war with France (1793) and the abolition of the slave trade (1807) contributed to Bristol's failure to keep pace with the newer manufacturing centres of Northern England and the West Midlands. The tidal Avon Gorge, which had secured the port during the Middle Ages, had become a liability. An 1804–09 plan to improve the city's port with a floating harbour designed by William Jessop was a costly error, requiring high harbour fees.

During the 19th century, Samuel Plimsoll, known as "the sailor's friend," campaigned to make the seas safer; shocked by overloaded vessels, he successfully fought for a compulsory load line on ships.

By 1867, ships were getting larger and the meanders in the river Avon prevented boats over 300 feet (90 m) from reaching the harbour, resulting in falling trade. The port facilities were migrating downstream to Avonmouth and new industrial complexes were founded there. Some of the traditional industries including copper and brass manufacture went into decline, but the import and processing of tobacco flourished with the expansion of the W.D. & H.O. Wills business.

Supported by new industry and growing commerce, Bristol's population (66,000 in 1801), quintupled during the 19th century, resulting in the creation of new suburbs such as Clifton and Cotham. These provide architectural examples from the Georgian to the Regency style, with many fine terraces and villas facing the road, and at right angles to it. In the early 19th century, the romantic medieval gothic style appeared, partially as a reaction against the symmetry of Palladianism, and can be seen in buildings such as the Bristol City Museum and Art Gallery, the Royal West of England Academy, and The Victoria Rooms. Riots broke out in 1793 and 1831; the first over the renewal of tolls on Bristol Bridge, and the second against the rejection of the second Reform Bill by the House of Lords. The population by 1841 had reached 140,158.

The Diocese of Bristol had undergone several boundary changes by 1897 when it was "reconstituted" into the configuration which has lasted into the 21st century.

20th century

From a population of about 330,000 in 1901, Bristol grew steadily during the 20th century, peaking at 428,089 in 1971. Its Avonmouth docklands were enlarged during the early 1900s by the Royal Edward Dock. Another new dock, the Royal Portbury Dock, opened across the river from Avonmouth during the 1970s. As air travel grew in the first half of the century, aircraft manufacturers built factories. The unsuccessful Bristol International Exhibition was held on Ashton Meadows in the Bower Ashton area in 1914. After the premature closure of the exhibition the site was used, until 1919, as barracks for the Gloucestershire Regiment during World War I.

Bristol was heavily damaged by Luftwaffe raids during World War II; about 1,300 people living or working in the city were killed and nearly 100,000 buildings were damaged, at least 3,000 beyond repair. The original central shopping area, near the bridge and castle, is now a park containing two bombed churches and fragments of the castle. A third bomb-damaged church nearby, St Nicholas was restored and after a period as a museum has now re-opened as a church. It houses a 1756 William Hogarth triptych painted for the high altar of St Mary Redcliffe. The church also has statues of King Edward I (moved from Arno's Court Triumphal Arch) and King Edward III (taken from Lawfords' Gate in the city walls when they were demolished about 1760), and 13th-century statues of Robert, 1st Earl of Gloucester (builder of Bristol Castle)  and Geoffrey de Montbray (who built the city's walls) from Bristol's Newgate.

The rebuilding of Bristol city centre was characterised by 1960s and 1970s skyscrapers, mid-century modern architecture and road building. Beginning in the 1980s some main roads were closed, the Georgian-era Queen Square and Portland Square were restored, the Broadmead shopping area regenerated, and one of the city centre's tallest mid-century towers was demolished. Bristol's road infrastructure changed dramatically during the 1960s and 1970s with the development of the M4 and M5 motorways, which meet at the Almondsbury Interchange just north of the city and link Bristol with London (M4 eastbound), Swansea (M4 westbound across the Severn Estuary), Exeter (M5 southbound) and Birmingham (M5 northbound). Bristol was bombed twice by the IRA, in 1974 and again in 1978.

The 20th-century relocation of the docks to Avonmouth Docks and Royal Portbury Dock, 7 miles (11 km) downstream from the city centre, has allowed the redevelopment of the old dock area (the Floating Harbour). Although the docks' existence was once in jeopardy (since the area was seen as a derelict industrial site), the inaugural 1996 International Festival of the Sea held in and around the docks affirmed the area as a leisure asset of the city.

21st century

From 2018, there were lively discussions about a new explicative plaque under a commemorative statue of one of the city's major benefactors in the 17th and 18th centuries. The plaque was meant to replace an original which made no reference to Edward Colston's past with the Royal Africa Company and the Bristol Slave Trade. On 7 June 2020 a statue of Colston was pulled down from its plinth by protestors and pushed into Bristol Harbour. The statue was recovered on 11 June and will become a museum exhibit.
