The institution of slavery refers to a system where individuals are owned by others and forced to work without compensation. This practice has existed in various forms throughout history, affecting millions of people across different cultures and societies. Slaves were often treated as property, lacking basic rights and freedoms. In many regions, such as the United States before the Civil War, slavery was a legal and economic system that supported industries like agriculture. The abolition of slavery in the 19th century marked a significant shift towards human rights, but its legacy continues to impact societies today.
