In America the slaves were African blacks; Indians starved themselves to death rather than live as slaves. From 1500 to 1820, hundreds of thousands of Europeans  were captured in war by Muslims and made slaves.

The last forms of legal slavery were outlawed in 1970 in the Arabian countries, but hidden slavery still exists today in remote parts of Africa such as the [[Sudan]] where Arabs own black slaves.

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.
