Slavery was found in the history of most civilizations. Slavery flourishes where there is a high demand for labor and not enough workers. When the workers are plentiful, slavery dies out because it is unprofitable. That is, it becomes cheaper to free a slave and hire low cost paid labor than to buy and maintain slaves. Typically, when it had almost died out, it was made illegal by the government, as in Brazil. | Slavery was found in the history of most civilizations.
