Bristol, United Kingdom

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, there was an important Jewish community in Bristol which survived 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.

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.

In the 1640s, during the English Civil War, the city was occupied by Royalists, who built the Royal Fort House on the site of an earlier Parliamentarian stronghold.

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 coast 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, with the city becoming one of the two leading outports in all of England by the middle of the 18th century (London being the other), as well as the third biggest city in the country.

The 18th century saw an expansion of Bristol's population (45,000 in 1750) and its role in the Atlantic trade in Africans taken for slavery to the Americas. Bristol and later Liverpool became centres of the Triangular Trade. Between the 1720s and 1740s, Bristol was Britain's primary slave trading port. In 1755, it had the largest number of slave traders in the country with 237, as against London's 147. 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.

Bristol was also a major supplier of slaves to South Carolina before 1750.
