History of slavery

Slavery is a system where people are treated as property and forced to do work they don't want to do. It has been around for a very long time. In the past, some countries used slavery to get more work done, like farming or building things. People were bought and sold like objects, and were often not paid for the work they did. This was very unfair and many people had to suffer because of it. Slavery was eventually abolished, but it still exists in some parts of the world today. In the United States, the first slaves were brought to the colonies in the 1600s, and slavery was officially abolished in the 19th century.
