Antebellum Slavery

In 19th century America, a major part of society was the presence of slavery. Slaves were the ones who worked the plantations in the south, and did most of the other labor. The economic, social, and political power was mainly controlled by those who owned 20 or more slaves. This was because cotton was becoming a major export of the southern US, especially after the invention of the cotton gin, which increased cotton production. The more cotton that was being produced, the more slaves that were needed. This led to more cotton being produced, which made more money, which allowed for more slaves. This cycle eventually led to slavery becoming economically entrenched in American society. There is an interesting website with graphs showing how as cotton growth expanded in the south, the number of slaves did as well.

A system that becomes so dependent on slavery for not only its economic power, but its social structure greatly affects human dignity. The government begins to classify the slaves by only the color of their skin, and not their skills or intelligence. This has been the way in America ever since Columbus landed in the Caribbean in 1492, he immediately enslaved the native peoples because of their race. The Americas have always been a land where one race thinks that they are better than the other, while overlooking their personal/physical traits.
Human dignity ultimately becomes corrupted by a system such as this. One example of this corruption is even written in the US Constitution, in Article 1, Section 2, Clause 3, where it reads "Representatives and direct Taxes shall be apportioned among the several States which may be included in the Union, according to their respective Numbers, which shall be determined by adding to the Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons." This eventually became know as the "Three-fifths rule" where blacks only counted as three fifths of a person when filing taxes and the number of Representatives in Congress. This showed that the government only classified the slaves based upon their race, and did not give them rights whatsoever.
