When Lincoln was elected President in 1860 South Carolina seceded almost immediately, followed in rapid sequence by Georgia, Alabama, Mississippi, Florida and Louisiana. Texas followed during early 1861, with Governor Sam Houston resisting. Then the waves of secession (then called "disunion") stopped. Lincoln was inaugurated March 4, 1861. Virginia didn't secede till April 17, 1861, after the first shots were fired at Fort Sumter, and Lincoln announced a token muster of Virginia troops. It was a very open question whether Virginia, then considered a Border State, would secede. Indeed a chunk of the state now known as West Virginia, and the part on the Delmarva Peninsula did not join the rest of the state in disuniting from the Union. I happen to believe that had Virginia (followed shortly by other border states such as North Carolina and Tennessee and yes I know Arkansas also seceded late but different situation) not seceded the crisis may well have gone the way of South Carolina's nullification crisis. Virginia was likely pushed to secede by the reality that the remaining Union might have abolished slavery with the Cotton States out of the Senate. The already seceded states, as of the beginning of April 1861 were South Carolina, Georgia, Florida, Louisiana, Mississippi and Texas. All of those states were deeply impoverished. Texas had recently been crippled by massive, independence-era debts. Without the late-seceding states the Confederacy had little ability to fight an actual war. Virginia's going out made them viable for a serious war, though they were likely doomed.
