actually the civil war was fought for many other reasons besides slavery...slavery wasnt driving force behind the civil war
True, but JQA had been dead for almost 15 years by the time the civil war came about.
That said, in the strictest sense, the end of slavery in the Northern states did start around the time the American revolution was over (Emancipation in Massachusetts was in 1777) and continued into the early 19th century.
However, the idea behind slavery (ie states rights) was an absolute reason behind the civil war, and in that respect, so was slavery itself.
