Gettysburg Address
19 Nov 1863
Causes: The Confederacy failed to invade DC and the war turned in favor of the Union. Lincoln gave a short speech at the Gettysburg Cemetary in honor of the fallen Union soldiers.
People: Abraham Lincoln
Effects: Lincoln declared that there would be a "new birth of freedom" in the US, meaning that slavery could not continue even once the North + South were reunited. And true to his words, slavery was officially over with the passage of the 13th Amendment after the war.
