I generally ignore responses, but this one was bad enough to justify a reply. The north invaded over taxes as Lincoln said in his first inaugural?
Lincoln doesn’t mention the word taxes once in his first inaugural. He also doesn’t use the terms: fund, levy, or even money. In fact his first inaugural is completely devoid of references to finance and the economy.
As for why the north actually “invaded” (you can’t really invade your own country), that’s because the south attempted to become its own country and in doing so initiated violence by bombarding Fort Sumter.
So the south broke away (over slavery) and then began the hostilities.
But you say this is all about taxes, a word which, again, is missing from the speech you cite as evidence of an invasion based on tax policy. Something Lincoln ACTUALLY said in his first inaugural is:
“You can have no conflict without being yourselves the aggressors.”
Whereupon the south decided to secede and start a war.
