it has high economical effect as The British economy was transformed by the Atlantic slave trade. In 1700, 80 per cent of British trade went to Europe from ports on the east and south coasts.
By 1800, 60 per cent of British trade went to Africa and America, sailing from the three main west coast ports - Glasgow, Liverpool and Bristol.
Ports such as London, Bristol and Liverpool prospered as a direct result of involvement in the slave trade. Other ports, such as Glasgow, profited from the tobacco trade. Thousands of jobs were created in Britain supplying goods and services to slave traders.
In a period that saw Britain industrialize, profits could be made by exporting manufactured British goods to Africa and then further profits accrued from imported slave products such as sugar, which became very fashionable with the British people.
The slave trade was important in the development of the wider economy - financial, commercial, legal and insurance institutions all emerged to support the activities of the slave trade. Some merchants became bankers and many new businesses were financed by profits made from slave-trading.
