Slavery refers to a condition in which an individual is treated as property and forced to perform work for another person or entity, usually through physical coercion or legal restrictions. It has been practiced throughout history in various forms, including chattel slavery, where individuals are considered personal property and can be bought and sold; bonded labor, where workers are required to pay off debts with their labor; and forced labor, which involves using force or the threat of force to compel someone to work against their will. Slaves are often treated as inferior and denied basic human rights such as freedom, education, and protection under the law. The abolition of slavery is considered a fundamental human right by many international organizations, including the United Nations.
