“That’s the first time I’ve heard that the American Revolution was motivated by slavery.”
I am not surprised. I am of the understanding that history isn’t taught in public schools much anymore.
If you read the DOI, I think you’ll find what I said is true.
I have read the Declaration of Independence and since neither slavery or property are mentioned then I don't see what supports your claim that the colonists rebelled to defend slavery. If you're referring to the "excited domestic insurrections amongst us" to mean slave rebellions, well, there is a lot to dispute in that.
