City and unitary authority (pop., 2001: 380,615), southwestern England. Lying at the confluence of the Rivers Avon and Frome, the city received its first charter in 1155. Long a centre of commerce, it was the point of departure in 1497 of John Cabot in his search for a route to Asia. During the 17th–18th centuries it prospered in the triangular trade (rum, molasses, and slaves) between West Africa and the West Indian and American plantation colonies. Though Bristol suffered a decline in trade in the early 19th century, it soon rebounded with the coming of the railway. It suffered severe damage from bombing in World War II but was rebuilt. Today it is an important shipping centre, especially for oil and food products.
