SMALLER PORTS
Ports on the south-west, south-east and north-west coasts of England, along with Glasgow, were also involved.

THE INDUSTRIAL REVOLUTION
Slavery contributed vastly to Britain's rise as an industrial nation. Slavers needed ships; crews needed provisions; traders needed goods to barter for enslaved Africans ? fetters; chains, padlocks, guns, pots, kettles; plantations needed machinery; rum factories needed bottles. Cotton picked by slave labour in New England was manufactured in Lancashire and sold on the colonial market, mostly Africa.

FINANCIAL SERVICES
Investors loaned money to slavers, bankers banked their profits, insurers insured their ships and cargoes. They and wealthy merchants built mansions and country houses; so the effect of the slave trade spread across Britain.
