Observations on the Slavery of Africans and Their Descendents gave the free produce movement its central argument. This movement promoted an embargo of all goods produced by slave labor, which were mainly cotton cloth and cane sugar, in favor of produce from the paid labor of free people. Though the free produce movement was not intended to be a religious response to slavery, most of the free produce stores were Quaker in origin, as with the first such store, that of Benjamin Lundy in Baltimore in 1826.
