Coartación, also known as slavery, is when someone is forced to work for someone else without any choice or compensation. It's like when your mom tells you to clean your room, but imagine if your mom had the power to make you clean her entire house every day and you could never leave or get paid for it. People who are in coartación are treated like property, and they don't have any say in their lives. It's a really bad thing that happened a long time ago, and thankfully today it's illegal in most places.
