The Daily Citizen has a pretty good article detailing the events surrounding the creation of the Confederate States of America in 1861:
February 4, 1861, fell on a Monday. On that day, delegates from six lower south states congregated at the Capitol in Montgomery, Ala., to form a national government that would be known as the Confederate States of America. Distinguished representatives were in attendance from South Carolina, Georgia, Florida, Alabama, Mississippi and Louisiana. Only Texas was missing from those that had seceded from the United States in the wake of Abraham Lincoln’s election, but the Texas delegates would be along just as soon as that state’s secession vote was confirmed. In the meantime, there was much to do and little time in which to do it.
This new government, everyone agreed, needed to be in operation prior to Lincoln’s March 4 inauguration.
