Final answer:
The first southern advocacy for secession did not occur after the election of Abraham Lincoln in 1860.
Step-by-step explanation:
False. The first southern advocacy for secession occurred before the election of Abraham Lincoln in 1860.
One example is the secession movement in South Carolina, which began shortly after the election of James Buchanan in 1856. The state believed that a Republican president, like Lincoln, would threaten their interests and rights.
This early advocacy for secession demonstrates the deep-rooted tension between the North and the South that eventually led to the outbreak of the Civil War.
