I dont see a document but i think i can still answer your question. Slaves were not considered people because they were owned by people and considered property.

We also have plenty of French-inspired cities, such as Baton Rouge, there is also an entire culture called Creole, that blends the culture of the French with Spanish, more Carribean is anything.
