Explain Lincoln’s central idea in his “ better angels of our nature “ speech on March 4,1861. What did he hope to accomplish

Explanation:

"Plainly, the central idea of secession, is the essence of anarchy." With this statement, Abraham Lincoln tried to show why the attempt of seven states to leave the American union peacefully was, in fact, a total violation of law and order. The Constitution required that the newly elected president of the United States take an oath to "preserve, protect and defend the Constitution of the United States," and so Lincoln explained how he would keep that Union together. Exactly one month before Lincoln delivered his First Inaugural Address on March 4, 1861, a provisional Confederate States of America had already drawn up a constitution and elected officers. Moreover, the departing president, James Buchanan, added to the new president's difficulties. While his December 1860 State of the Union Address argued that secession was not "an inherent constitutional right," Buchanan saw no constitutional provision that empowered the president "to coerce a state into submission."
