What did the north want, and what did the south want?

  The north was strongly against slavery, and the south believed that there should be slavery.  The southerners who wanted slavery were called abolitionists.  The north side won what they wished, and that has changed our country today.

Who was Abraham Lincoln, and what did he do for our country?
