How did the south Atlantic system affect the British economy

The South Atlantic system tied the entire economy of British colonies in a circular system. The British sold guns to Africans in exchange for slaves. The slaves were sold to the colonies and worked in the sugar and tobacco plantations that brought wealth to entire British economy

The South Atlantic system included the Spanish colonies in South and Central America, the Portuguese colony of Brazil, the sugar-producing islands of the Caribbean, West Africa, and the southern colonies in North America. Its most prominent products were silver, sugar, tobacco, African slaves, and, after 1800, cotton.
