caste system

caste system

Explanation:

After the American Revolutionary War, the south consolidated its plantation-based economy. These plantations were mostly of tobacco in the tidewater area, and of cotton in the deep south.

The plantations were worked by African Americans, who were slaves. They did not have civil or political rights, and were considered property. They could not hold property themselves, had no access to any education beyond what they needed to do their job, and could not buy their freedom. Finally, their descendants were also slaves.

In a caste system, people are born into a caste, and never leave it, no matter what they do. The South was a caste system because land-owning whites were born rich and free, and this condition did not change, while African Americans were born poor and enslaved, and would die in the same condition.
