I have looked into this topic off and on -- The laws of slavery from the slave-holding States, were absolutely a source of conflict and included in the first shots fired. There were trade issues and disagreement on monetary policy (no single currency yet?).

At that time in US history, multiple large land acquisitions (new states) were in progress after the massive land sale by the French and the repeated defeat of the Spanish in the Far West. Modern Texas had been finalized and the US Presidential Election had regional candidates competing vigorously.

The civil war famously was not very bloody for the first year, with a lot of arguing more than shooting, but neither side stepped back, and the restriction of navigation on land and water led to more battles.
