what greatest concern or emergency was mentioned by lincoln in his speech

The greatest concern or emergency mentioned by Abraham Lincoln in his speech, particularly in the Gettysburg Address, was the survival of democracy and the nation itself amid the ongoing Civil War. Lincoln emphasized that the war was testing whether a nation "conceived in liberty, and dedicated to the proposition that all men are created equal" could endure. He framed the conflict as a crucial test of whether such a government "of the people, by the people, for the people, shall not perish from the earth." The preservation of the Union and the principle of democracy were at the heart of his message, urging dedication to the cause for which the soldiers had given their lives so that the nation might live and democracy might survive
