Lincoln became president, after getting more votes than Stephan A. Douglas. Lincoln wanted the country to be united, so he said that the country would either be a slave or free state. Once the word got out, some states seceded and joined together as the Confederate states. Of course, Abraham Lincoln was not in favor of this, so a war began for him to get the land back for the Union. After many wars, the confederate states surrendered and the Union was whole again. Unfortunately, Abraham got shot in the back of his head at a play, I believe, that was in the southern territory....
Hope this helps :)
