Bristol and Liverpool became centres of the Triangular Trade.
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.
Bristol's modern economy is built on the creative media, electronics and aerospace industries, and the city-centre docks have been redeveloped as centres of heritage and culture.
The city has the largest circulating community currency in the U.
Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373, when it became a county of itself.
