Sugar, slavery, and the plantation economy

Sugar plantations dominated Caribbean economies from the eighteenth century into the twentieth, shaping the region's economy for generations. At their regional peak, these plantations produced between 80 and 90 percent of the sugar consumed in Western Europe: a staggering share of one continent's supply chain resting on Caribbean soil and Caribbean labor.

Until abolition, the labor system that sustained sugar production was the enslavement of African people brought by the transatlantic slave trade described in an earlier lesson. After abolition took hold elsewhere in the Caribbean, indentured laborers from India, China, and Portugal were brought to some islands to replace that labor.

The work itself was relentless. Cane had to be cut, then chopped, ground, pressed or soaked, and heated quickly before the sugar spoiled: every stage demanded skilled labor performed under the coercion of slavery, with little margin for delay.

Regional abolition came on its own schedule. Britain's Slave Trade Act of 1807 banned the transatlantic trade within the British empire, and the Emancipation Bill of 1833 freed more than half a million enslaved people in the British Caribbean by 1838, decades ahead of Puerto Rico's own abolition in 1873.

On the island itself, sugar cane came to dominate the economy specifically during the late nineteenth and twentieth centuries, spanning both the last years of Spanish colonial rule and the U.S. rule that followed. Puerto Rico's own 1765 census, with 5,037 enslaved people out of a total of 44,883, shows a notably lower proportion of enslaved population than major sugar colonies like Barbados or Jamaica, where individual plantations and their enslaved populations were on a far larger scale.
