this post is really behind because I missed Nooms' and just found it on my work computer open from last week.
So I'm saging this post but this just really has to be said.>>226472
This entire concept is clearly based on ignorance and I suggest you get the facts. Read this cheap textbook, it will tell you everything and it is 1000% accurate, I wrote papers on much of this stuff from archived primary source materials during the course I had which uses this book.
get the oldest edition, used is fine, it's like $5 so you have absolutely no fucking excuse to continue to believe such mistruths from now on.
International slave trade was ended because of the Brits abolishing it (watch Amistad) but, it far from ended the trade in the US but made it super-lucrative and it boomed until the war ended it.
All the new territories being added were conflicted between slave and free states because the new territories would sway the legislative will of the Congress one way or the other and this created immense pressure for new territories, far more of a factor than Manifest Destiny as to our pressure to expand.
Regardless, slaves became valuable commodity and especially with the addition fo the cotton gin, there was absolutely no limit to how much money could be made from plantation slaves and it went from bad to worse, this is the period in which slaves lost free time entirely.
