Sugar increased in popularity enormously in the 18th century. Grown and refined across the New World, it was a source of great wealth for plantation owners.

Sugarcane cultivation drove a surge in the use of slaves, and in 1791 abolitionists in Britain organized boycotts of slave-sourced sugar.  This may have been the first time consumers used their purchasing power to confront an ethical issue.
