Eli Whitney and the Cotton Gin
So I wanted to be able to show my students how slavery spread, especially after the invention of the cotton gin. The map above is what I found. You can change the dates and watch the increase of the slave population even after legal importation of them had stopped. Speaking of Whitney, here is a nice flash image of how the cotton gin works.
