Another important group of slaves to mention were the slaves brought over from Africa. The first slaves came over with Christopher Columbus from the very beginning on his earliest voyages. However in the few hundred years, the Atlantic Slave trade would begin delivering slaves, imported by Spain and other colonizers, by the millions. Many of the large scale productions were run by forced slave labor. They were a part of sugar and coffee production, farming (beans, rice, corn, fruit, etc.), Mining, whale oil and multiple other jobs. Slaves were also house workers, servants, military soldiers, and much more. To say the least these people were property and treated as such. Though indigenous slaves existed, they were no match in quantity and lack of quality jobs when compared to the African slave. The slave population was massive compared to the better known slave ownership in the United States. After 1860 Brazil alone had imported over 4 million slaves, which only represented about 35% of the Atlantic slave trade. Despite the large number of slaves in Latin America, there was not as much reproduction of slaves amongst the population. Because most of the slaves then were African-born, they were more subject to rebellion. The United States involvement in the slave trade is well known amongst North America, however it hides a larger and in some ways crueler operation in the south which had a much longer history.
