This is the best prestident in the 19th centry because he kept the Nation together. If Abe Lincoln didn't do anything the United States of America wouldn't even be called the United States of America. We would be like Europe, a buch of contries just living in little space. But it's thanks to this great man that We, (Untied States,) are together. He belived in a Untied Nation, and he risk going to war just to keep that dream alive. We need to do that now. We need to be untied or Our emimes would just destroy us.
