Desire of the railroad companies to build rail lines on a deal of new land that open up to whether it was for the "free" or "slaves" .
The article states "<span>Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas all left the Union by February 1. On February 4, delegates from all these states except Texas met in Montgomery, Alabama, to create and staff a government called the Confederate States of America." so 2 they voted to secede
