What were 3 effects of Lincolns warning to the south?

Lincoln's warning to the South, particularly his assertion in his inaugural address that secession was unlawful, aimed to uphold the Union and deter further rebellion. Firstly, it reinforced the federal government's determination to maintain national unity, signaling to Southern states that their actions would face resistance. Secondly, it rallied support from Unionists in the border states and among Northern citizens who were committed to preserving the Union. Lastly, it intensified tensions, contributing to the outbreak of the Civil War as Southern leaders perceived the warning as a direct threat to their sovereignty and way of life.
