When Lincoln said the nation wasso conceived and so dedicated and what is he referring to?

When Lincoln referred to the nation as "so conceived and so dedicated," he was speaking about the principles of equality and democracy enshrined in the Declaration of Independence. This phrase emphasizes the idea that the United States was founded on the belief that all men are created equal and that the nation was committed to the ideals of liberty and justice for all. Lincoln's Words, particularly in the context of the Gettysburg Address, highlight the ongoing struggle to uphold these principles, especially during the Civil War.
