Your wrong. The Civil war was fought because the confederate states of America fired on Fort Sumter, the establishment of the confederacy the freeing of the slaves all of those happened as a consequence or prior to the actual war.

If you want to get that reductive than I am right. The Civil war happened because the Confederate States of America fired on Fort Sumter and everything else was ancillary. Just like WW1 happened because the Archduke Franz Ferdinand got assassinated.

Youre argument is overly reductive and your ignorant of history
