Essays / African American Slave Trade [3]

I'm new to this forum and I've been looking around. I'm stuck looking for a direction for my thesis on the African American Slave Trade from 1440 to 1640. I was thinking about comparing it to how it affects today's African American society. However, I cannot come up with enough main ideas to make sufficient body paragraphs. If anyone could provide some assistance that would be great, I am just looking for a direction for this paper just to stretch it out to about six pages.

Thank you in advance.
