Abraham Lincoln Created out of the Entire Gettysburg Address. Abraham Lincoln is considered by many historians to have been the greatest American president. Lincoln's achievements include guiding his country through the most devastating experience in its national history (The Civil War) and freeing the slaves. His assassination just at the war's end assured his continuing fame. There is very little doubt as to how popular and important Lincoln is to this generation. He is constantly quoted, studied and looked up for inspiration. What is really amazing is that not only was Abraham Lincoln simply one of if not the greatest leader in American History, he also gave the greatest speech in American History.
