I'm Harriet Beecher Stowe, the author of "Uncle Tom's Cabin," I'm known to have "helped lay the groundwork for the Civil War."
My novel was known to have helped start the Civil War. It is fictional and supports anti-slavery.
My novel helped Christians, mothers, and free states empathize with the slaves.
We can not lose our entire institution! We must work harder to keep slavery!
We need to end slavery! It's wrong and absolutely injustice!
Uncle Tom's Cabin had a negative effect for the South because they didn't support anti-slavery, they depended on slaves for their institution.
Uncle Tom's Cabin had a neutral effect on North. They were a little upset that they hadn't done anything about it sooner. But, it wasn't a negative thing because their institution didn't depend on slavery.
My popular novel that supported anti-slavery, Uncle Tom's Cabin, helped cause the Civil War because it started a huge argument between North and South over slavery.
