Sugar also played a big role in a less commendable development: the slave trade. Nearly all the sugar Britons consumed was grown on West Indian estates worked by slaves. We have a narrow tendency to associate slavery exclusively with the plantation economy of the southern United States, but in fact plenty of other people got rich from slavery, not least the traders who shipped 3.1 million Africans across the ocean before the United Kingdom abolished the trade in humans in 1807.
