Here is a list of Secession docs I compiled.

Most people I debate try to use these as proof positive the war was about slavery. If you actually read them, you will see they are nothing more than a list of grievances' the South had against the actions of the Federal government. There is not one sentence in these docs they state we are going to war for slavery.
Read them, get past the word slave.
