All these are good reasons, but secession started because of one man got elected to the White House. If Douglas would have won, or Fremont or Edwin Stanton, no threat was made to secede. It was Lincoln and the Republican Party which fueled the fires of secession. The argument over slavery was their motto."If they think it right and we think it wrong should we cast our votes to their veiw?" "I think Not!" To me this means they meant to continue the abolition trail until they won. They won the Presidency and the South seceded, because of tariffs? No. Because Lincoln and his Republicans came to power.

What was the cause of the War for Southern Independence? Abraham Lincoln and the Republican Party.
