In the United States, there was a division between slave states in the South and free states in the North. At the start of the American Civil War, there were 34 states in the United States, 15 of which were slave states, all of which had slave codes. The 19 free states did not have slave codes, although they still had laws regarding slavery and enslaved people, covering such issues as how to handle slaves from slave states, whether they were runaways or with their owners.
