I think that our greatest president was Abraham Lincoln. Their are several reasons why he is the best president the world has seen. The first reason is that he was the one that fought against slavery. He was the one that ultimately freed the slaves from their owners. He was the one that gave them opportunities to live a life of freedom without anyone telling them what to do and when to do it. He also won the Civil War against the south. He even made sure the slaves were freed from their owners by sending the army to check up on the farms and make sure there weren't any slaves. He was the first president that actually tried to help the slaves and he was the one that created a bond of trust between them. That ultimately led the north to win the Civil War. Because he couldn't of done it with the help of the slaves that wanted to fight for their freedom. That's why i think Abraham Lincoln is the best president we have seen.
