Abolition is the act of getting rid of something, like the abolition of slavery.
One of the greatest moments in the history of the United States was the abolition of slavery: when we ended slavery as an institution. That’s a dramatic and important case, but abolition can refer to getting rid of any system, practice, or institution. Sports leagues would love to achieve the abolition of performance-enhancing drugs. Everyone would probably like to see the abolition of rats from all cities. When there’s an abolition, something is abolished — it’s gone.
