The correct answers are B) Abraham Lincoln, a Republican who opposed the expansion of slavery in the federal territories, was elected president in 1860. D) The Georgia Platform included acceptance of the Compromise of 1850 and a warning that Congress must not violate any of its terms.
Those were the two events that increased support for secession among Georgia's leaders.
Georgia played a key role as one of the southern states that were convinced that recently elected President, Abraham Lincoln meant more problems for southerners due to his ideas on slavery and support of abolition.
It was just a matter of time after the election of Abraham Lincoln to start secession. The first state to secede was South Carolina, and then, the other southern states followed it. The American Civil War was close.
