Why was slavery called a "pecuiliar institution"? How did the institution of slavery function and what was its impact on the slave?

The slavery was a peculiar institution because the slaves used to show in the market as goods where they presented a pen or non-living things in the row.

Explanation:

The expansion and high demand of cotton increased the demand of labor. These workers (salves) were not paid by their owners. Their owners used them as a commodity and not as human being. They used to work for long working hours without any leave or other facility at the work place.
