The practice of selling prisoners of war and enemies as slaves was common in many parts of the world throughout history. It wasn't limited to any one group or region. Different societies and empires engaged in this practice for various reasons, including:
* Economic gain: Slaves were a valuable commodity, providing labor for agriculture, mining, and other industries.
* Punishment: Selling enemies into slavery could be a form of punishment or retribution for defeat in war.
* Social control: Slavery could be a means of controlling conquered populations and ensuring their submission.
The Portuguese were active participants in the transatlantic slave trade, but they were not the only ones involved. Many other European nations, as well as African and Asian kingdoms, played a role in this horrific system.
Here are some specific examples of groups who engaged in this practice:
* The Portuguese themselves: They captured and enslaved people in Africa, particularly in the 15th and 16th centuries.
* African kingdoms: Some African leaders participated in the slave trade, often selling prisoners of war or criminals to European traders.
* Ottoman Empire: The Ottomans captured and enslaved Europeans, especially during wars with Christian powers.
It's crucial to remember that generalizations about entire groups of people can be dangerous and inaccurate. The practice of enslaving prisoners of war and enemies was widespread and complex, involving various actors with diverse motivations.
