Keeping slavery was not what they were concerned with and the Corwin Amendment simply reaffirmed the existing status quo --- i.e. slavery was constitutional, and the political reality that there was not a sufficient constitutional majority to change that dynamic. It was a meaningless Amendment.
What the Slave Power demanded was expansion of slavery to all states and territories, and on that point, Lincoln refused to budge an inch.
Unless you happened to be a slave. The Corwin Amendment (supported by Lincoln) made slavery PERMANENT.
What the Slave Power demanded was expansion of slavery to all states and territories, and on that point, Lincoln refused to budge an inch.
Contrary to the 7-2 decision of the Supreme Court. Despite decades of several territories being open to slavery, the number of free blacks/slaves was insignificant. There was no demand for slavery to expand.
