What is a good hook and thesis statement about for an essay about the life of a slave?

I have a few examples you could use for a good hook. I would need to see the whole assignment to know about the thesis statement.

1: Anytime we hear the word "slavery", we tend to think of the Southern United States during the Pre-Civil war era.

2: Slavery has always been the most shocking phenomena of our world.

Hope this helps! :)

Nevermore and lenore are some examples.
