Secessionists argued that the United States Constitution was a contract among sovereign states that could be abandoned at any time without consultation and that each state had a right to secede. After intense debates and statewide votes, seven Deep South cotton states passed secession ordinances by February 1861 (before Abraham Lincoln took office as president), while secession efforts failed in the other eight slave states. Delegates from those seven formed the CSA in February 1861, selecting Jefferson Davis as the provisional president. Unionist talk of reunion failed and Davis began raising a 100,000 man army.
