Slavery is a system where individuals are owned by others and forced to work without pay. Throughout history, many societies have practiced slavery, often targeting specific groups based on race or ethnicity. In the United States, for example, millions of African Americans were enslaved from the 17th to the 19th centuries, enduring harsh conditions and brutal treatment. Racism is the belief that one race is superior to another, leading to discrimination and prejudice. This ideology has often justified the practice of slavery, as enslaved individuals were dehumanized and viewed as inferior. The legacy of slavery and racism continues to impact societies today, contributing to ongoing social and economic inequalities.
